How one widow has changed how women solo travel

After Yvonne Vickers' husband passed away in 2014, she thought her opportunities to travel and see the world had slipped away. Yvonne had always been a keen traveller and went on trips with her married friends after becoming a widow, but she "got over being the third wheel", she admitted to <a href="https://travel.nine.com.au/latest/cruising-solo-female-older-passengers/9553953c-84e8-418a-9c2b-8c9b847b9ba4" target="_blank" rel="noopener">9Travel</a>. Still wanting to see the world on her own terms, Yvonne took to Facebook where she created a group seeking like-minded women who share her passion for adventure. Now, the Find A Female Cruise or Travel Buddy is an ever-growing group that has connected thousands of women looking for travel companions. Whether they're single, widowed, or just married to someone who doesn't want to travel, the group is open to women across the globe to join. Thanks to her newfound community, Yvonne has taken 41 cruises and dozens of land trips since her husband's death, all while making friends for life, and the rest of the group's members are in the same boat. "It's wonderful to get feedback from ladies saying that it's helped to change their life," Yvonne said. "That's the rewarding part of it for me." Members can make a post in the group, detailing a cruise sailing or trip that they have their eye on booking, to see if anyone else would like to join them. "We have a lot of widows in our group who are cashed up and want to travel but don't have anyone to travel with or share their experiences with," Yvonne said. "The group gives them the opportunity to be able to do that." "There are also a lot of ladies who are married but their husbands don't want to travel. It gives them the opportunity to be able to travel." Yvonne says that cruising is a perfect way for older females to travel, especially if they're on their own. "It's a really safe way to travel as a solo female," she says, also noting that it's an easy way to get around and see places. Recently, she did a 35-day trip around Hawaii with a group of women from the group. For the Find A Female Cruise or Travel Buddy group, there's even more fun trips on the horizon. Yvonne just came back from a trip to Japan with 14 group members, and is heading to Bali in August with a friend she made through the group. Image credits: Nine News \ Facebook

Do red bags get loaded onto a plane first? Travel hack goes viral

One TikTok user has racked up over 75 million views for their hack which warns travellers against buying red suitcases. The reason behind it? He claims that red suitcases are always loaded onto a plane first - meaning that they will be the last ones to come out at the baggage carousel. The <a href="https://www.tiktok.com/@airportlife_/video/7359248989134327072" target="_blank" rel="noopener">viral video</a> showed a plane's cargo being loaded, with all the red bags being loaded first. Many commenters have shared their theories on why this might be the case. "If the red are at the back then they are less likely to get left behind when unloading," one wrote. "So that it's easier to check if there is any bag left at end corner of loading area and prevent missing out black bags at dark corners, maybe," another added. However, a spokesperson for KLM Royal Dutch Airlines has debunked this theory and claimed that the video is "nonsense" and "was made purposefully to mislead or provide false information". They also said that there was simply not enough time for their baggage handlers to sort suitcases out by colour. The question of "Do red bags get loaded onto a plane first?" also made its way to Reddit, after the video went viral, and one user who claimed to be a ramp worker denied the theory. "If we had taken the time and brain power to load bags based on colour I'd still be loading flights from 2015." Image: TikTok

Nat Barr quizzes Jim Chalmers over one major budget flaw

Nat Barr has quizzed treasurer Jim Chalmers over one major flaw in the federal budget. On Tuesday night, Chalmers <a href="https://oversixty.com.au/finance/money-banking/biggest-winners-and-losers-of-the-2024-25-federal-budget" target="_blank" rel="noopener">handed down</a> his third federal budget that prioritised cost-of-living relief, with one major initiative saving Aussies big on their next energy bills. All Australian families will get $300 off their annual electricity bill, while small businesses will also get a $325 rebate for their bills. Chalmers joined Nat Barr on Sunrise on Wednesday morning to discuss the initiative further, as the host pointed out one major flaw in the government's plan. “If you’re earning a million dollars, why do you need a $300 power rebate?” Barr asked. But Chalmers said wealthier Australians weren’t the focus of the rebate, as everyday Aussies struggling with the rising cost of living were sure to benefit. “It is primarily for people doing it tough — you know, millions and millions of Australians are under cost-of-living pressure,” he said. “We’re trying to help. So more help is on the way for millions of people under the pump. Whether it is a tax cut for every taxpayer or energy bill relief for every household.” Barr asked Chalmers if people earning $1 million were “under pressure”, but the treasurer said offering specifically targeted assistance was logistically impossible. “Once you go beyond (pensioners), you have to design a whole new system because the energy retailers that we use to provide this help, they don’t have income information for people,” he said. “We deliver this relief via energy bills, via the retailers. There’s not a system that allows you to slice and dice that beyond providing it either to people on pensions and payments.” Barr's comments were echoed online, with many slamming the logistics of the rebate on social media. "I'm sure Gina Rinehart is stoked she's getting $300 back on her energy bills," one person commented. Another added, "If this stupid government gives me $300 off my energy bills it goes straight to charity. Join me if you can afford it." A third wrote, "Feel like there should be an exemption in the $300 energy rebate for anyone who has ever slept under a doona with the aircon on." Image credits: Sunrise

Tallinn International Airport – Estonia This international airport is fast gaining a reputation as a good place to catch some sleep, but it’s advised that you make sure you sleep near other travellers. The website says, “Make sure they are actual travellers and not homeless people – it is sometimes hard to tell in certain airports.” 7. Tokyo Haneda International Airport – Japan Due partly to its proximity to the rest of town, Tokyo Haneda International Airport is a very popular airport to sleep at, to the point where the site says, “If you are staying at a busy airport overnight, you'll have to get there early if you want a good spot, especially during the summer season.” 6. Porto Francisco Sá Carneiro Airport – Portugal While this airport provides a great option for travellers looking to catch up on a little bit of shut-eye, they still have to be creative.

10 tips for a better night’s sleep in a hotel room

From noisy neighbours to unbearable bedding, a good night’s sleep in a hotel room can be hard to come by. Here are 10 tips to help you get decent shut eye. 1. Book a room midway down a hallway This is generally the quietest part of the floor, way from ice and wending machines, laundry facilities, exits, closets and any other places where sudden noises might occur. 2. Try to avoid rooms facing a pool While the view is something to admire, pools can also be the sight of noise generating late-night gathering and any sounds generally echo loudly off the water. 3. Inquire at the front desk about pillow options If the wrong pillow gives you back or neck pain have a chat to the front desk when checking in. Most hotels stock pillows of varying firmness, and can offer a better fit. 4. Pack earplugs and eyeshades When you’re struggling to get to sleep the tiniest noise or ray of light can end up being a huge distraction. Nip this in the bud by packing earplugs and eyeshades. 5. Turn your mobile phone off Mobile notifications can be a huge distraction (particularly when they’re coming from friends and family in different time zones). Turn your phone off, and enjoy the bliss. 6. Make use of your ‘do not disturb’ sign If you’re planning to sleep in make sure you put your ‘do not disturb’ sign on the outside doorknob, otherwise you might get a rude awakening from a housekeeper. 7. Report any noises immediately Sometimes a quick pound of the wall will quiet down a noisy neighbour, but this doesn’t always work. If the people in the room next to you won’t keep quiet, make sure you let the front desk know and they can take the necessary actions. 8. Adjust the room temperature Most people sleep better in a cooler room, so make sure you adjust the temperature to whatever is the best fit for you to get sleep. Even just opening the window a tiny little crack can make a big difference in terms of your overall comfort levels. 9. Ask the front desk about blackout shades Particularly if you’re staying in a city that’s full of lights, noises and distractions, blackout shades can provide you with a level of peace and comfort that will help you sleep. 10. Consider bringing your own sheets Particularly if you’ve got skin sensitives, it’s generally a good idea to bring your own sheets (if you’ve got enough space). The familiar scent and feel will really help you sleep. Image credits: Shutterstock

Photos are everywhere. What makes a good one?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/t-j-thomson-503845">T.J. Thomson</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> We upload some <a href="https://theconversation.com/3-2-billion-images-and-720-000-hours-of-video-are-shared-online-daily-can-you-sort-real-from-fake-148630">3 billion images online each day</a>. We make <a href="https://www.tandfonline.com/doi/full/10.1080/1051144X.2023.2281163">most of these photos on smartphones</a> and use these devices to document everything from gym progress and our loved ones to a memorable meal. But what makes a “quality” photo? Many people, even those who make images for work, struggle to answer. They often say something along the lines of “I know it when I see it”. But knowing some dimensions of a quality photograph can help make your images stand out and make you a <a href="https://medialiteracy.org.au/media-literacy-framework/">more literate</a> media maker and consumer. Quality can be relative, but knowing the various dimensions at play can help you draw on those that are most relevant for your particular audience, context and purpose. I identified <a href="https://doi.org/10.1177/14648849241253136">six dimensions</a> which will impact the quality of photographs. Here’s what I learnt – and what you can apply to your own photographs. <h2>1. Production and presentation</h2> Think of the factors <a href="https://journals.sagepub.com/doi/full/10.1177/1522637918823261">in front of and behind the lens</a>. If you know you’re being recorded, this can affect your behaviour compared to a candid depiction. You might be more or less comfortable posing for a friend or family member than for a stranger. This comfort, or its lack, can lead to more stiff and awkward poses, or ones that look more natural and confident. Presentation circumstances, like the viewing size and context, also matter. A group shot can make a nice statement piece above a fireplace, but it wouldn’t have the same effect as a profile photo. Be aware of how “busy” your image is, and whether the viewing conditions are well-suited for the nature of your photo. Images with lots of elements, fine textures or other details need to be viewed large to be fully appreciated. Images with fewer, larger and simpler elements can usually be appreciated at smaller sizes. <h2>2. Technical aspects</h2> Technical aspects include proper exposure – meaning the image isn’t too dark or too bright – adequate focus, and appropriate camera settings. Some of these camera settings, like shutter speed, affect whether motion is seen as frozen or blurred. If the image is too blurry, too pixelated, or too light or dark, these technical aspects will negatively impact the photograph’s quality. But some motion blur, as distinct from camera shake, can make more dynamic an otherwise static composition. <h2>3. Who or what is shown</h2> Who or what is shown in the photographs we see is affected, in part, by access and novelty. That’s why we often make more photos during our holidays compared to documenting familiar settings. Some people or locations can be <a href="https://journals.sagepub.com/doi/full/10.1177/1329878X221094374">under-represented</a> and photographing them can lead to more visibility, and, depending on the context, a more empowering framing. Consider in your photography if you’re including people who are typically under-represented, such as older individuals, people of colour, people living with disabilities and queer people. Also consider whether you’re representing them in stereotypical or disempowering ways. As examples, <a href="https://www.tandfonline.com/doi/abs/10.1080/22041451.2022.2137237">when photographing older people</a>, consider whether you’re showing them as lonely, isolated, passive, or in need of mobility aids. <h2>4. Composition</h2> Composition includes positioning of elements in the frame, the balance between positive and negative space, and depth, among others. Generally, images that centre the subject of interest aren’t as visually engaging as images that offset the subject of interest. This is what’s known as the <a href="https://www.adobe.com/au/creativecloud/photography/discover/rule-of-thirds.html">rule-of-thirds</a> approach. Likewise, images that have no depth are generally not as interesting as images with a clear foreground, midground and background. “Seeing through things” with your compositions can help increase the visual depth of your photos alongside their visual appeal. <h2>5. The psycho-physiological</h2> The psycho-physiological concerns how the viewer reacts to what is shown. This includes the <a href="https://psycnet.apa.org/record/2011-07236-024">biological reaction</a> we have to seeing certain colours, for example the way the colour red can increase our heart rate. It also can include the feeling we have when seeing a photo of someone we know. The most powerful photos use colour and other elements of visual language strategically for a specific effect. Looking at these images might evoke a specific emotion, such as empathy or fear, and influence how the viewer responds. <h2>6. Narrative</h2> Narrative concerns the storytelling quality of the image. Images can show something in a literal way (think a photograph from a real estate listing) or they can tell a bigger story about the content represented or about the human condition (think about some of the iconic photos that emerged during Australia’s <a href="https://journals.sagepub.com/doi/abs/10.1177/1329878X211008181">black summer bushfire season</a>). Literal photos help us see what something or someone looks like but they might not have as much of an impact as iconic photos. For example, the well-known photo of three-year-old Syrian boy Aylan Kurdi’s lifeless body on a beach in Turkey <a href="https://www.reuters.com/article/idUSKBN14V2MG/">boosted fundraising for refugees</a> 100-fold. <h2>A more thoughtful process</h2> Next time you pull out your smartphone to make an image, don’t just “<a href="https://www.digitalphotomentor.com/do-you-wait-for-the-decisive-moment-or-do-you-spray-and-pray/">spray and pray</a>”. Try to pre-visualise the story you want to tell and wait for the elements to line up into place. Being aware of aesthetic and ethical considerations alongisde technical ones and emotional resonance can all help engage viewers and lead to more standout imagery. To challenge yourself further, consider taking your phone off full-auto mode and play with camera settings to see how they impact the resulting photos.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/229011/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/t-j-thomson-503845">T.J.

Sleep wrinkles are real. Here’s how they leave their mark

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/yousuf-mohammed-858232">Yousuf Mohammed</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>; <a href="https://theconversation.com/profiles/khanh-phan-1489820">Khanh Phan</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>, and <a href="https://theconversation.com/profiles/vania-rodrigues-leite-e-silva-1497208">Vania Rodrigues Leite E. Silva</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> You wake up, stagger to the bathroom and gaze into the mirror. No, you’re not imagining it. You’ve developed face wrinkles overnight. They’re sleep wrinkles. Sleep wrinkles are temporary. But as your skin loses its elasticity as you age, they can set in. Here’s what you can do to minimise the chance of them forming in the first place. <h2>How side-sleeping affects your face</h2> Your skin wrinkles for a number of reasons, including ageing, sun damage, smoking, poor hydration, habitual facial expressions (such as grinning, pouting, frowning, squinting) and sleeping positions. When you sleep on your side or stomach, your face skin is <a href="https://academic.oup.com/asj/article/36/8/931/2613967">squeezed and crushed</a> a lot more than if you sleep on your back. When you sleep on your side or stomach, gravity presses your face against the pillow. Your face skin is distorted as your skin is stretched, compressed and pulled in all directions as you move about in your sleep. You can reduce these external forces acting on the face by sleeping on your back or changing positions frequently. <h2>Doctors can tell which side you sleep on by looking at your face</h2> In a young face, sleep wrinkles are transient and disappear after waking. Temporary sleep wrinkles can become persistent with time and repetition. As we <a href="https://pubmed.ncbi.nlm.nih.gov/19624425/">age</a>, our skin <a href="https://pubmed.ncbi.nlm.nih.gov/22233477/">loses elasticity</a> (recoil) and extensibility (stretch), creating <a href="https://pubmed.ncbi.nlm.nih.gov/27329660/">ideal conditions</a> for sleep wrinkles or lines to set in and last longer. The time spent in each sleeping position, the magnitude of external forces applied to each area of the face, as well as the surface area of contact with the pillow surface, also <a href="https://pubmed.ncbi.nlm.nih.gov/27329660/">affects</a> the pattern and rate of sleep wrinkle formation. Skin specialists can often recognise this. People who favour sleeping on one side of their body tend to have a flatter face on their sleeping side and more visible sleep lines. <h2>Can a night skincare routine avoid sleep wrinkles?</h2> Collagen and elastin are two primary components of the dermis (inner layer) of skin. They form the skin structure and maintain the elasticity of skin. <figure class="align-center "><img src="https://images.theconversation.com/files/593034/original/file-20240509-16-hz2ha3.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/593034/original/file-20240509-16-hz2ha3.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=395&fit=crop&dpr=1 600w, https://images.theconversation.com/files/593034/original/file-20240509-16-hz2ha3.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=395&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/593034/original/file-20240509-16-hz2ha3.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=395&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/593034/original/file-20240509-16-hz2ha3.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=496&fit=crop&dpr=1 754w, https://images.theconversation.com/files/593034/original/file-20240509-16-hz2ha3.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=496&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/593034/original/file-20240509-16-hz2ha3.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=496&fit=crop&dpr=3 2262w" alt="Skin structure" /><figcaption>The dermis is the inner layer of skin. <a class="source" href="https://www.shutterstock.com/image-vector/skin-structure-old-young-1707589036">mermaid3/Shutterstock</a></figcaption></figure> Supplementing collagen through skincare routines to enhance skin elasticity can <a href="https://pubmed.ncbi.nlm.nih.gov/32799362/">help reduce</a> wrinkle formation. <a href="https://pubmed.ncbi.nlm.nih.gov/30287361/">Hyaluronic</a> acid is a naturally occurring molecule in human bodies. It holds our skin’s collagen and elastin in a proper configuration, stimulates the production of <a href="https://www.mdpi.com/1420-3049/26/15/4429">collagen</a> and adds hydration, which can help slow down wrinkle formation. Hyaluronic acid is one of the most common <a href="https://pubmed.ncbi.nlm.nih.gov/30287361/">active ingredients</a> in skincare creams, gels and lotions. Moisturisers can hydrate the skin in <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1473-2165.2009.00421.x">different ways</a>. “Occlusive” substances produce a thin layer of oil on the skin that prevents water loss due to evaporation. “Humectants” attract and hold water in the skin, and they can differ in their capacity to bind with water, which influences the degree of skin hydration. <h2>Do silk pillowcases actually make a difference?</h2> Silk pillowcases can make a difference in wrinkle formation, if they let your skin glide and move, rather than adding friction and pressure on a single spot. If you can, use silk sheets and silk pillows. Studies have also <a href="https://academic.oup.com/asj/article/36/8/931/2613967">shown</a> pillows designed to reduce mechanical stress during sleep can prevent skin deformations. Such a pillow <a href="https://www.scirp.org/journal/paperinformation?paperid=67035#:%7E:text=Introduction-,The%20duration%20of%20sleep%20and%20the%20position%20of%20the%20face,permanent%20sleep%20lines%20with%20time.">could be useful</a> in slowing down and preventing the formation of certain facial wrinkles. Sleeping on your back can reduce the risk of sleep lines, as can a nighttime routine of moisturising before sleep. Otherwise, lifestyle choices and habits, such quitting smoking, drinking plenty of water, a healthy diet (eating enough vegetables, <a href="https://www.tandfonline.com/doi/full/10.1080/07315724.2001.10719017?casa_token=uD1flbkLyKUAAAAA%3AsMTWPmxzO3fGHAI41o80B_bWrGrOrvQFeJwF2FtIEnkd73Qmjvyhxr1-GO2kU8_Yc2LYgZp56DqHVg">fruits</a>, nuts, seeds, healthy fats, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5452251/pdf/nutrients-09-00521.pdf">yogurt and other fermented foods</a>) and regular use of sunscreens can help improve the appearance of the skin on our face.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/217380/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/yousuf-mohammed-858232">Yousuf Mohammed</a>, Dermatology researcher, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>; <a href="https://theconversation.com/profiles/khanh-phan-1489820">Khanh Phan</a>, Postdoctoral Research Fellow, Frazer Institute, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>, and <a href="https://theconversation.com/profiles/vania-rodrigues-leite-e-silva-1497208">Vania Rodrigues Leite E.

Terminal lucidity: why do loved ones with dementia sometimes ‘come back’ before death?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/yen-ying-lim-355185">Yen Ying Lim</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/diny-thomson-1519736">Diny Thomson</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Dementia is often described as “the long goodbye”. Although the person is still alive, dementia slowly and irreversibly chips away at their memories and the qualities that make someone “them”. Dementia eventually takes away the person’s ability to communicate, eat and drink on their own, understand where they are, and recognise family members. Since as early as the <a href="https://pubmed.ncbi.nlm.nih.gov/21764150/">19th century</a>, stories from loved ones, caregivers and health-care workers have described some people with dementia suddenly becoming lucid. They have described the person engaging in meaningful conversation, sharing memories that were assumed to have been lost, making jokes, and even requesting meals. It is estimated <a href="https://pubmed.ncbi.nlm.nih.gov/20010032/">43% of people</a> who experience this brief lucidity die within 24 hours, and 84% within a week. Why does this happen? <h2>Terminal lucidity or paradoxical lucidity?</h2> In 2009, researchers Michael Nahm and Bruce Greyson coined the term “<a href="https://pubmed.ncbi.nlm.nih.gov/21764150/">terminal lucidity</a>”, since these lucid episodes often occurred shortly before death. But not all lucid episodes indicate death is imminent. <a href="https://alz-journals.onlinelibrary.wiley.com/doi/10.1002/alz.13667">One study</a> found many people with advanced dementia will show brief glimmers of their old selves more than six months before death. Lucidity has also been <a href="https://www.sciencedirect.com/science/article/pii/S0167494311001865?via%3Dihub">reported</a> in other conditions that affect the brain or thinking skills, such as meningitis, schizophrenia, and in people with brain tumours or who have sustained a brain injury. Moments of lucidity that do not necessarily indicate death are sometimes called <a href="https://alz-journals.onlinelibrary.wiley.com/doi/10.1002/alz.12579">paradoxical lucidity</a>. It is considered paradoxical as it defies the expected course of neurodegenerative diseases such as dementia. But it’s important to note these episodes of lucidity are temporary and sadly do not represent a reversal of neurodegenerative disease. <h2>Why does terminal lucidity happen?</h2> Scientists have struggled to explain why terminal lucidity happens. Some episodes of lucidity have been reported to occur in the presence of loved ones. Others have reported that <a href="https://psywb.springeropen.com/articles/10.1186/s13612-014-0024-5">music can sometimes improve lucidity</a>. But many episodes of lucidity do not have a distinct trigger. <a href="https://www.sciencedirect.com/science/article/pii/S0300957223002162">A research team from New York University</a> speculated that changes in brain activity before death may cause terminal lucidity. But this doesn’t fully explain why people suddenly recover abilities that were assumed to be lost. Paradoxical and terminal lucidity are also very difficult to study. Not everyone with advanced dementia will experience episodes of lucidity before death. Lucid episodes are also unpredictable and typically occur without a particular trigger. And as terminal lucidity can be a joyous time for those who witness the episode, it would be unethical for scientists to use that time to conduct their research. At the time of death, it’s also difficult for scientists to interview caregivers about any lucid moments that may have occurred. Explanations for terminal lucidity extend beyond science. These moments of mental clarity may be a way for the dying person to say final goodbyes, gain closure before death, and reconnect with family and friends. Some believe episodes of terminal lucidity are representative of the person connecting with an afterlife. <h2>Why is it important to know about terminal lucidity?</h2> People can have a variety of reactions to seeing terminal lucidity in a person with advanced dementia. While some will experience it as being peaceful and bittersweet, others may find it deeply confusing and upsetting. There may also be an urge to modify care plans and request lifesaving measures for the dying person. Being aware of terminal lucidity can help loved ones understand it is part of the dying process, acknowledge the person with dementia will not recover, and allow them to make the most of the time they have with the lucid person. For those who witness it, terminal lucidity can be a final, precious opportunity to reconnect with the person that existed before dementia took hold and the “long goodbye” began.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/202342/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/yen-ying-lim-355185">Yen Ying Lim</a>, Associate Professor, Turner Institute for Brain and Mental Health, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/diny-thomson-1519736">Diny Thomson</a>, PhD (Clinical Neuropsychology) Candidate and Provisional Psychologist, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

A tax on sugary drinks can make us healthier. It’s time for Australia to introduce one

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/peter-breadon-1348098">Peter Breadon</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> and <a href="https://theconversation.com/profiles/jessica-geraghty-1530733">Jessica Geraghty</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> Sugary drinks cause weight gain and <a href="https://www.nature.com/articles/s41574-021-00627-6">increase the risk</a> of a range of diseases, including diabetes. The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2792842">evidence shows</a> that well-designed taxes can reduce sugary drink sales, cause people to choose healthier options and get manufacturers to reduce the sugar in their drinks. And although these taxes haven’t been around long, there are already signs that they are making people healthier. It’s time for Australia to catch up to the rest of the world and introduce a tax on sugary drinks. As our new Grattan Institute <a href="https://grattan.edu.au/report/sickly-sweet/">report</a> shows, doing so could mean the average Australian drinks almost 700 grams less sugar each year. <h2>Sugary drinks are making us sick</h2> The share of adults in Australia who are obese has tripled since 1980, from <a href="https://theconversation.com/mapping-australias-collective-weight-gain-7816">10%</a> to more than <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/waist-circumference-and-bmi/latest-release">30%</a>, and diabetes is our <a href="https://www.diabetesaustralia.com.au/about-diabetes/diabetes-in-australia/">fastest-growing</a> chronic condition. The costs for the health system and economy are measured in the billions of dollars each year. But the biggest costs are borne by individuals and their families in the form of illness, suffering and early death. Sugary drinks are a big part of the problem. The more of them we drink, the greater our risk of <a href="https://www.nature.com/articles/s41574-021-00627-6">gaining weight</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2963518/">developing type 2 diabetes</a>, and suffering <a href="https://academic.oup.com/eurpub/article/31/1/122/5896049?login=false">poor oral health</a>. These drinks have no real nutrients, but they do have a lot of sugar. The average Australian consumes <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/apparent-consumption-selected-foodstuffs-australia/latest-release">1.3</a> times the maximum recommended amount of sugar each day. Sugary drinks are responsible for more than one-quarter of our daily sugar intake, more than any other major type of food. You might be shocked by how much sugar you’re drinking. Many 375ml cans of soft drink contain eight to 12 teaspoons of sugar, nearly the entire daily recommended limit for an adult. Many 600ml bottles blow our entire daily sugar budget, and then some. The picture is even worse for disadvantaged Australians, who are more likely to have <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/diabetes/latest-release">diabetes</a> and <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/waist-circumference-and-bmi/latest-release">obesity</a>, and who also consume the most sugary drinks. <h2>Sugary drink taxes work</h2> Fortunately, there’s a proven way to reduce the damage sugary drinks cause. More than <a href="https://ssbtax.worldbank.org/">100 countries</a> have a sugary drinks tax, covering most of the world’s population. <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2792842">Research</a> shows these taxes lead to higher prices and fewer purchases. Some taxes are specifically designed to encourage manufacturers to change their recipes and cut the sugar in their drinks. Under these “tiered taxes”, there is no tax on drinks with a small amount of sugar, but the tax steps up two or three times as the amount of sugar rises. That gives manufacturers a strong incentive to add less sugar, so they reduce their exposure to the tax or avoid paying it altogether. This is the best result from a sugary drinks tax. It means drinks get healthier, while the tax is kept to a minimum. In countries with tiered taxes, manufacturers have slashed the sugar in their drinks. In the United Kingdom, the share of products above the tax threshold <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1003025">decreased dramatically</a>. In 2015, more than half (52%) of products in the UK were above the tax threshold of 5 grams of sugar per 100ml. Four years later, when the tax was in place, that share had plunged to 15%. The number of products with the most sugar – more than 8 grams per 100ml – declined the most, falling from 38% to just 7%. The Australian drinks market today looks similar to the UK’s before the tax was introduced. Health benefits take longer to appear, but there are already promising signs that the taxes are working. Obesity among primary school-age girls has fallen in <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1004160">the UK</a> and <a href="https://jamanetwork.com/journals/jamapediatrics/fullarticle/2786784">Mexico</a>. Oral health has also improved, with studies reporting fewer children going to hospital to get their teeth removed in <a href="https://nutrition.bmj.com/content/6/2/243">the UK</a>, and reduced dental decay <a href="https://pubmed.ncbi.nlm.nih.gov/33853058/">in Mexico</a> and <a href="https://www.ajpmonline.org/article/S0749-3797(23)00069-7/abstract">Philadelphia</a>. One <a href="https://www.ajpmonline.org/article/S0749-3797(23)00158-7/fulltext">study from the United States</a> found big reductions in gestational diabetes in cities with a sugary drinks tax. <h2>The tax Australia should introduce</h2> Like successful taxes overseas, Australia should introduce a sugary drink tax that targets drinks with the most sugar: <ul> <li>drinks with 8 grams or more of sugar per 100ml should face a $0.60 per litre tax</li> <li>drinks with 5–8 grams should be taxed at $0.40 per litre</li> <li>drinks with less than 5 grams of sugar should be tax-free.</li> </ul> This means a 250ml Coke, which has nearly 11 grams of sugar per 100ml, would cost $0.15 more. But of course consumers could avoid the tax by choosing a sugar-free soft drink, or a bottle of water. Grattan Institute <a href="https://grattan.edu.au/report/sickly-sweet/">modelling</a> shows that under this tiered tax, Australians would drink about 275 million litres fewer sugary drinks each year, or the volume of 110 Olympic swimming pools. The tax is about health, but government budgets also benefit. If it was introduced today, it would raise about half a billion dollars in the first year. Vested interests such as the beverages industry have fiercely resisted sugary drink taxes around the world, issuing disingenuous warnings about the risks to poor people, the sugar industry and drinks manufacturers. But our new report shows sugary drink taxes have been introduced smoothly overseas, and none of these concerns should hold Australia back. We certainly can’t rely on industry pledges to voluntarily reduce sugar. They have been <a href="https://www.cambridge.org/core/journals/public-health-nutrition/article/trends-in-sugar-content-of-nonalcoholic-beverages-in-australia-between-2015-and-2019-during-the-operation-of-a-voluntary-industry-pledge-to-reduce-sugar-content/EE662DE7552670ED532F6650C9D56939">weak</a> and misleading, and <a href="https://www.theguardian.com/australia-news/2024/apr/10/sugar-increase-in-fanta-and-sprite-prompts-calls-for-new-tax-on-australia-food-and-drinks-industry">failed to stick</a>. It will take many policies and interventions to turn back the tide of obesity and chronic disease in Australia, but a sugary drinks tax should be part of the solution. It’s a policy that works, it’s easy to implement, and most Australians <a href="https://bmjopen.bmj.com/content/9/6/e027962">support it</a>. The federal government should show it’s serious about tackling Australia’s biggest health problems and take this small step towards a healthier future.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/228906/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/peter-breadon-1348098">Peter Breadon</a>, Program Director, Health and Aged Care, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> and <a href="https://theconversation.com/profiles/jessica-geraghty-1530733">Jessica Geraghty</a>, Senior Associate, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Jock Zonfrillo honoured one year after passing

Jock Zonfrillo has been remembered by his wife, Lauren Fried, and friend, Jimmy Barnes, a year after the MasterChef judge's tragic death. Fried organised a moving piper memorial for her late husband, which friends and family attended. His wife took to Instagram to share a montage of images from their life together with the caption: "One year. We watched the sunrise today in true Scottish style - wind, pouring rain, and Jock's beloved bagpipes as our soundtrack." "A day for us to try to accept that he's not coming home, that this is forever, that we were lucky he was ours," she added. "Forever their Papa and Dad. Forever My Love." <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/C6aIKvmvRsj/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/C6aIKvmvRsj/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Jock Zonfrillo (posts by Loz) (@zonfrillo)</a> </div> </blockquote> Jimmy Barnes shared a video of the poignant bagpipe-led tribute held at dawn in Bondi Beach on Wednesday, as the rocker, Zonfrillo's family and friends watched on. “On the beach before dawn, a lone piper playing in memory of our dear friend Jock Zonfrillo who left us one year ago,” the rocker posted with a video of the piper playing. “It was a true Scottish morning, cold, wet, windy, sand blowing onto our faces.

MasterChef Australia also paid tribute to the fallen judge on the first anniversary of his passing, with a wooden bench featuring a plaque dedicated to the late chef in the MasterChef gardens at the show's Melbourne headquarters. “In memory of Jock, one year on. ‘In life, you give back more than you take,’” the post read. Fans took to the comments to share their tributes to the late judge. "Beautiful. Still difficult not to see him on MasterChef anymore," one wrote. "Fatherhood looked so good on him. I can’t believe a year has passed so quickly and yet so slowly at the same time…." another said. "I can't believe it's been a year. My heart is with the MC family today. I shed some tears with the opening show of this season. He is surely missed," a third wrote. Image: Instagram

Caring

Better sleep is a protective factor against dementia

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/andree-ann-baril-1494268">Andrée-Ann Baril</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a> and <a href="https://theconversation.com/profiles/matthew-pase-1494296">Matthew Pase</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Dementia is a progressive loss of cognitive abilities, such as memory, that is significant enough to have an impact on a person’s daily activities. It can be caused by a number of different diseases, including <a href="https://alzheimer.ca/en/about-dementia/what-alzheimers-disease">Alzheimer’s</a>, which is the most common form. Dementia is caused by a loss of neurons over a long period of time. Since, by the time symptoms appear, many changes in the brain have already occurred, many scientists are focusing on studying the risk and protective factors for dementia. A risk factor, or conversely, a protective factor, is a condition or behaviour that increases or reduces the risk of developing a disease, but does not guarantee either outcome. Some risk factors for Alzheimer’s disease and dementia, such as age or genetics, are not modifiable, but there are several other factors we can influence, <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">specifically lifestyle habits and their impact on our overall health</a>. These risk factors include depression, lack of physical activity, social isolation, high blood pressure, obesity, diabetes, excessive alcohol consumption and smoking, as well as poor sleep. We have been focusing our research on the question of sleep for over 10 years, particularly in the context of the <a href="https://www.nhlbi.nih.gov/science/framingham-heart-study-fhs">Framingham Heart Study</a>. In this large community-based cohort study, ongoing since the 1940s, the health of surviving participants has been monitored to the present day. As researchers in sleep medicine and epidemiology, we have expertise in researching the role of sleep and sleep disorders in cognitive and psychiatric brain aging. As part of our research, we monitored and analyzed the sleep of people aged 60 and over to see who did — or did not — develop dementia. <h2>Sleep as a risk or protective factor against dementia</h2> Sleep appears to play an essential role in a number of brain functions, such as memory. Good quality sleep <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2793873">could therefore play a vital role in preventing dementia</a>. Sleep is important for maintaining <a href="https://www.science.org/doi/10.1126/science.1241224">good connections in the brain</a>. Recently, research has revealed that sleep seems to have a function similar to that of a garbage truck for the brain: <a href="https://doi.org/10.1016/j.mad.2023.111899">deep sleep could be crucial for eliminating metabolic waste from the brain</a>, including clearing certain proteins, such as those known to accumulate in the brains of people with Alzheimer’s disease. However, the links between deep sleep and dementia still have to be clarified. <h2>What is deep sleep?</h2> During a night’s sleep, we go through several <a href="http://ceams-carsm.ca/en/a-propos-du-sommeil/">sleep stages</a> that succeed one another and are repeated. NREM sleep (non-rapid eye movement sleep) is divided into light NREM sleep (NREM1 stage), NREM sleep (NREM2 stage) and deep NREM sleep, also called slow-wave sleep (NREM3 stage). The latter is associated with several restorative functions. Next, REM sleep (rapid eye movement sleep) is the stage generally associated with the most vivid dreams. An adult generally spends around 15 to 20 per cent of each night in deep sleep, if we add up all the periods of NREM3 sleep. Several sleep changes are common in adults, such as going to bed and waking up earlier, sleeping for shorter periods of time and less deeply, and waking up more frequently during the night. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=279&fit=crop&dpr=1 600w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=279&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=279&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=350&fit=crop&dpr=1 754w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=350&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=350&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Sleep stages, and the role of deep sleep for brain health. (Andrée-Ann Baril)</figcaption></figure> <h2>Loss of deep sleep linked to dementia</h2> Participants in the <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2810957">Framingham Heart Study</a> were assessed using a sleep recording — known as polysomnography — on two occasions, approximately five years apart, in 1995-1998 and again in 2001-2003. Many people showed a reduction in their deep slow-wave sleep over the years, as is to be expected with aging. Conversely, the amount of deep sleep in some people remained stable or even increased. Our team of researchers from the Framingham Heart Study followed 346 participants aged 60 and over for a further 17 years to observe who developed dementia and who did not. Progressive loss of deep sleep over time was associated with an increased risk of dementia, whatever the cause, and particularly Alzheimer’s type dementia. These results were independent of many other risk factors for dementia. Although our results do not prove that loss of deep sleep causes dementia, they do suggest that it could be a risk factor in the elderly. Other aspects of sleep may also be important, such as its duration and quality. <h2>Strategies to improve deep sleep</h2> Knowing the impact of a lack of deep sleep on cognitive health, what strategies can be used to improve it? First and foremost, if you’re experiencing sleep problems, it’s worth talking to your doctor. Many sleep disorders are underdiagnosed and treatable, particularly through behavioural (i.e. non-medicinal) approaches. Adopting good sleep habits can help, such as going to bed and getting up at consistent times or avoiding bright or blue light in bed, like that of screens. You can also avoid caffeine, limit your alcohol intake, maintain a healthy weight, be physically active during the day, and sleep in a comfortable, dark and quiet environment. The role of deep sleep in preventing dementia remains to be explored and studied. Encouraging sleep with good lifestyle habits could have the potential to help us age in a healthier way.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/222854/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/andree-ann-baril-1494268">Andrée-Ann Baril</a>, Professeure-chercheure adjointe au Département de médecine, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a> and <a href="https://theconversation.com/profiles/matthew-pase-1494296">Matthew Pase</a>, Associate Professor of Neurology and Epidemiology, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Could not getting enough sleep increase your risk of type 2 diabetes?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> Not getting enough sleep is a common affliction in the modern age. If you don’t always get as many hours of shut-eye as you’d like, perhaps you were concerned by news of a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">recent study</a> that found people who sleep less than six hours a night are at higher risk of type 2 diabetes. So what can we make of these findings? It turns out the relationship between sleep and diabetes is complex. <h2>The study</h2> Researchers analysed data from the <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a>, a large biomedical database which serves as a global resource for health and medical research. They looked at information from 247,867 adults, following their health outcomes for more than a decade. The researchers wanted to understand the associations between sleep duration and type 2 diabetes, and whether a healthy diet reduced the effects of short sleep on diabetes risk. As part of their involvement in the UK Biobank, participants had been asked roughly how much sleep they get in 24 hours. Seven to eight hours was the average and considered normal sleep. Short sleep duration was broken up into three categories: mild (six hours), moderate (five hours) and extreme (three to four hours). The researchers analysed sleep data alongside information about people’s diets. Some 3.2% of participants were diagnosed with type 2 diabetes during the follow-up period. Although healthy eating habits were associated with a lower overall risk of diabetes, when people ate healthily but slept less than six hours a day, their risk of type 2 diabetes increased compared to people in the normal sleep category. The researchers found sleep duration of five hours was linked with a 16% higher risk of developing type 2 diabetes, while the risk for people who slept three to four hours was 41% higher, compared to people who slept seven to eight hours. One limitation is the study defined a healthy diet based on the number of servings of fruit, vegetables, red meat and fish a person consumed over a day or a week. In doing so, it didn’t consider how dietary patterns such as time-restricted eating or the Mediterranean diet may modify the risk of diabetes among those who slept less. Also, information on participants’ sleep quantity and diet was only captured at recruitment and may have changed over the course of the study. The authors acknowledge these limitations. <h2>Why might short sleep increase diabetes risk?</h2> In people with <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">type 2 diabetes</a>, the body becomes resistant to the effects of a hormone called insulin, and slowly loses the capacity to produce enough of it in the pancreas. Insulin is important because it regulates glucose (sugar) in our blood that comes from the food we eat by helping move it to cells throughout the body. We don’t know the precise reasons why people who sleep less may be at higher risk of type 2 diabetes. But <a href="https://doi.org/10.7759/cureus.23501">previous research</a> has shown sleep-deprived people often have increased <a href="https://doi.org/10.1186/1476-511X-9-125">inflammatory markers</a> and <a href="https://doi.org/10.1007/s00125-015-3500-4">free fatty acids</a> in their blood, which <a href="https://doi.org/10.1007/s11892-018-1055-8">impair insulin sensitivity</a>, leading to <a href="https://doi.org/10.7759/cureus.23501">insulin resistance</a>. This means the body struggles to use insulin properly to regulate blood glucose levels, and therefore increases the risk of type 2 diabetes. Further, people who don’t sleep enough, as well as people who sleep in irregular patterns (such as shift workers), experience disruptions to their body’s natural rhythm, known as the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5995632/">circadian rhythm</a>. This can interfere with the release of hormones like <a href="https://doi.org/10.1210/edrv.18.5.0317">cortisol, glucagon and growth hormones</a>. These hormones are released through the day to meet the body’s changing energy needs, and normally keep blood glucose levels nicely balanced. If they’re compromised, this may reduce the body’s ability to handle glucose as the day progresses. These factors, and <a href="https://www.science.org/doi/10.1126/sciadv.aar8590">others</a>, may contribute to the increased risk of type 2 diabetes seen among people sleeping less than six hours. While this study primarily focused on people who sleep eight hours or less, it’s possible longer sleepers may also face an increased risk of type 2 diabetes. Research has previously shown a U-shaped correlation between sleep duration and type 2 diabetes risk. A <a href="https://doi.org/10.2337/dc14-2073">review</a> of multiple studies found getting between seven to eight hours of sleep daily was associated with the lowest risk. When people got less than seven hours sleep, or more than eight hours, the risk began to increase. The reason sleeping longer is associated with increased risk of type 2 diabetes may be linked to <a href="https://doi.org/10.2337/dc15-0186">weight gain</a>, which is also correlated with longer sleep. Likewise, people who don’t sleep enough are more likely to be <a href="https://doi.org/10.1016/j.sleh.2017.07.013">overweight or obese</a>. <h2>Good sleep, healthy diet</h2> Getting enough sleep is an important part of a healthy lifestyle and may reduce the risk of type 2 diabetes. Based on this study and other evidence, it seems that when it comes to diabetes risk, seven to eight hours of sleep may be the sweet spot. However, other factors could influence the relationship between sleep duration and diabetes risk, such as individual differences in sleep quality and lifestyle. While this study’s findings question whether a healthy diet can mitigate the effects of a lack of sleep on diabetes risk, a wide range of evidence points to the benefits of <a href="https://www.who.int/initiatives/behealthy/healthy-diet">healthy eating</a> for overall health. The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">authors of the study</a> acknowledge it’s not always possible to get enough sleep, and suggest doing <a href="https://pubmed.ncbi.nlm.nih.gov/33137489/">high-intensity interval exercise</a> during the day may offset some of the potential effects of short sleep on diabetes risk. In fact, exercise <a href="https://doi.org/10.1016/j.jshs.2023.03.001">at any intensity</a> can improve blood glucose levels.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225179/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, Casual Academic, Faculty of Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, Senior Lecturer, School of Public Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Australia outraged over one woman's callous Bondi remarks

A conservative commentator has caused widespread outrage for her "disgraceful" comments over the recent stabbing in Bondi Junction Westfield, which resulted in the deaths of six people. On Thursday, the shopping centre held a <a href="https://oversixty.com.au/health/caring/bondi-junction-westfield-reopens-after-stabbing-tragedy" target="_blank" rel="noopener">community reflection day</a> in which locals were invited to attend the reopening of the shopping centre and pay their respects to this impacted by the tragedy. Shops remained closed for the occasion, while Westfield operator Scentre Group's Chief executive Elliott Rusanow said the day of reflection was intended to help people feel comfortable returning to the site. Despite hundreds of people showing up for the emotional day, commentator Kobie Thatcher shared her wildly unpopular opinions on the matter, saying the day of reflection was "woke virtue signalling", adding that those affected by the tragedy have "had days to mourn". "Bondi Junction will reopen tomorrow for a 'Community Reflection Day'," Ms Thatcher wrote in a post on social media on Wednesday. "No retail trade. What kind of woke nonsense is this?" "Surely the last few days when the shopping centre was closed and people were leaving flowers were enough time for reflection. Let businesses reopen.'" The post was met with a furious wave of backlash, with former Lord Mayor of Sydney Lucy Turnbull saying the day had nothing to do with wokeness. "Nope. It is respectful and empathetic," Ms Turnbull said. Another called on Ms Thatcher to "have some compassion" for those affected, with one person writing, "You weren't there. You weren't directly affected by what happened." "Let those who were there decide what is the best method to deal with the trauma that they faced on the day." Further commenters also defended the day of reflection, saying it was an important step in healing. "Is it letting businesses reopen or forcing workers to return to a massacre site when they're still concerned for their health and well-being?" "So, Kobie, business is more important than the loss of innocent human lives and some time to mourn for them." Another simply said, "Kobie is disgraceful." Image credits: Facebook / Getty Images

"Big one for shenanigans": Aussie larrikin paddles a giant pumpkin down a river

In potentially the most Aussie story ever and a suspected world first, one bloke has pinched his mate's award-winning pumpkin to turn into a paddle boat and sail down the Tumut River. The enormous pumpkin was grown by farmer Mark Peacock, who grew the vegetable to a whopping 407kg and would regularly post updates on the gourd's growing progress on Facebook. The pumpkin even earned a fitting name, Tormund after a character in Game of Thrones, and was used to feed his livestock. After the pumpkin had served its purpose, Peacock's friend and local canoe club commodore Adam Farquharson saw a once in a lifetime opportunity. Sporting a sailor hat and pipe, he navigated the hollowed-out pumpkin, dubbed ‘Cinderella’, down the Tumut River in New South Wales’ Riverina region, much to the amusement of bystanders. “Barry Humphries said that he’s a big fan of the unnecessary, and I am too. I’m a big one for shenanigans,” he told <a title="www.abc.net.au" href="https://www.abc.net.au/news/2024-04-16/man-turns-mammoth-400kg-pumpkin-into-a-canoe/103708438">ABC Riverena</a><a title="www.abc.net.au" href="https://www.abc.net.au/news/2024-04-16/man-turns-mammoth-400kg-pumpkin-into-a-canoe/103708438">.</a> While initially surprised by Farquharson’s antics, Mr Peacock acknowledged that it was characteristic of his friend’s sense of humour to do something out of the ordinary to make people smile. “He’s really hilarious. But he’s random, occasionally,” he said. “I intentionally grew this as a family project and then started doing Facebook updates every week.” For Mr Farquharson, the voyage was simply about enjoying himself and giving locals an opportunity for a laugh. Farquharson joked about potential future exploits but remained grounded about his brief moment of fame as “Popeye the Pumpkin Man.” “I think the worldwide fame will wear off pretty soon. I won’t end up like Taylor Swift. I’ll just get back to life as normal,” he said. Reflecting on the unusual journey, Mr Farquharson humorously considered preserving the pumpkin as a national curiosity by placing it on a pedestal among Australian sporting royalty. “It was a sad moment. I did jokingly say to my wife that I should petition the prime minister to have it preserved and put next to Phar Lap’s heart at the National Museum,” he told the ABC. “She thought I was an idiot.” Image credits: Facebook

There are new flu vaccines on offer for 2024. Should I get one? What do I need to know?

<a href="https://theconversation.com/profiles/allen-cheng-94997">Allen Cheng</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Influenza is a common respiratory infection. Although most cases are relatively mild, flu can cause more severe illness in young children and older people. Influenza virtually <a href="https://pubmed.ncbi.nlm.nih.gov/33243355/">disappeared</a> from Australia during the first years of the COVID-19 pandemic when public health restrictions reduced contact between people. Since 2022, it has returned to a seasonal pattern, although the flu season has started and peaked a few months earlier than before 2020. It’s difficult to predict the intensity of the flu season at this point in the year, but we can sometimes get clues from the northern hemisphere. There, the season <a href="https://www.who.int/tools/flunet">started</a> <a href="https://gis.cdc.gov/grasp/fluview/flu_by_age_virus.html">earlier</a> than usual for the third year running (peaking in early January rather than late February/March), with a similar number of reported cases and hospitalisations to the previous year. Influenza vaccines are recommended annually, but there are now an increasing number of different vaccine types. Here’s what to know about this year’s shots, available from <a href="https://www.health.gov.au/topics/immunisation/vaccines/influenza-flu-vaccine">this month</a>. <h2>What goes into a flu vaccine?</h2> Like other vaccines, influenza vaccines work by “training” the immune system on a harmless component of the influenza virus (known as an antigen), so it can respond appropriately when the body encounters the real virus. Influenza strains are constantly changing due to genetic mutation, with the pace of genetic change <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10421855">much higher</a> than for SARS-CoV-2 (the virus that causes COVID). The strains that go into the vaccine are <a href="https://www.who.int/teams/global-influenza-programme/vaccines/who-recommendations">reviewed</a> twice each year by the World Health Organization (WHO), which selects vaccine strains to match the next season’s predicted circulating strains. All current influenza vaccines in <a href="https://www.tga.gov.au/resources/publication/meeting-statements/aivc-recommendations-composition-influenza-vaccines-australia-2024">Australia</a> contain four different strains (known as quadrivalent vaccines). One of the strains appeared to <a href="https://www.nejm.org/doi/full/10.1056/NEJMp2314801">disappear</a> during the COVID pandemic, and the WHO has recently <a href="https://cdn.who.int/media/docs/default-source/influenza/who-influenza-recommendations/vcm-southern-hemisphere-recommendation-2024/202309_qanda_recommendation.pdf?sfvrsn=7a6906d1_5">recommended</a> dropping this strain from the vaccine. It’s expected trivalent (three strain) vaccines will become available in the near future. <h2>What’s different about new flu vaccines?</h2> There are eight brands of flu vaccines <a href="https://www.health.gov.au/resources/publications/atagi-statement-on-the-administration-of-seasonal-influenza-vaccines-in-2024?language=en">available</a> in Australia in 2024. These include egg-based vaccines (Vaxigrip Tetra, Fluarix Tetra, Afluria Quad, FluQuadri and Influvac Tetra), cell-based vaccines (Flucelvax Quad), adjuvanted vaccines (Fluad Quad) and high-dose vaccines (Fluzone High-Dose Quad). Until recently, the process of manufacturing flu vaccines has remained similar. Since the development of the influenza vaccine in the <a href="https://www.who.int/news-room/spotlight/history-of-vaccination/history-of-influenza-vaccination">1940s</a>, influenza viruses were grown in chicken eggs, then extracted, inactivated, purified and processed to make up the egg-based vaccines that are still used widely. However, there have been several enhancements to influenza vaccines in recent years. Older people’s immune systems tend not to respond as strongly to vaccines. In some flu vaccines, adjuvants (components that stimulate the immune system) are included with the influenza antigens. For example, an adjuvant is used in the Fluad Quad vaccine, recommended for over 65s. Studies <a href="https://ncirs.org.au/sites/default/files/2021-02/Adjuvanted%20influenza%20vaccine%20vs%20standard%20dose%20influenza%20vaccine%20SoF%20EP%20E2D%20tables_26%20Feb%202021_Final.pdf">suggest</a> adjuvanted influenza vaccines are slightly better than standard egg-based vaccines without adjuvant in older people. An alternative approach to improving the immune response is to use higher doses of the vaccine strains. An example is Fluzone High-Dose Quad – another option for older adults – which contains the equivalent of four doses of a standard influenza vaccine. Studies <a href="https://ncirs.org.au/sites/default/files/2022-05/HD%20vs%20sIV%20SoF%20EP%20E2D_March%202022_Final.pdf">suggest</a> the high dose vaccine is better than the standard dose vaccine (without an adjuvant) in preventing hospitalisation and complications in older people. Other manufacturers have updated the manufacturing process. Cell-based vaccines, such as Flucelvax Quad, use cells instead of eggs in the manufacturing process. Other vaccines that are <a href="https://www.cdc.gov/flu/prevent/advances.htm">not yet available</a> also use different technologies. In the past, <a href="https://pubmed.ncbi.nlm.nih.gov/31151913/">manufacturing issues</a> with egg-based vaccines have reduced their effectiveness. Using an alternative method of production provides some degree of insurance against this in the future. <h2>What should I do this year?</h2> Given indications this year’s flu season may be earlier than usual, it’s probably safest to get your vaccine early. This is particularly <a href="https://www.health.gov.au/resources/publications/atagi-statement-on-the-administration-of-seasonal-influenza-vaccines-in-2024?language=en">important</a> for those at highest risk of severe illness, including older adults (65 years and over), those with chronic medical conditions, young children (six months to five years) and Aboriginal and Torres Strait Islander people. Influenza vaccines are also recommended in pregnancy to protect both the mother and the baby for the first months of life. Influenza vaccines are widely available, including at GP clinics and pharmacies, while many workplaces have occupational programs. For high-risk groups, <a href="https://www.health.gov.au/topics/immunisation/vaccines/influenza-flu-vaccine">four of the vaccines</a> are subsidised by the Australian government through the <a href="https://www.health.gov.au/our-work/national-immunisation-program">National Immunisation Program</a>. In older people, a number of vaccines are now recommended: <a href="https://www.health.gov.au/sites/default/files/2024-03/atagi-statement-on-the-administration-of-covid-19-vaccines-in-2024.pdf">COVID</a> and influenza, as well as one-off courses of <a href="https://www.health.gov.au/sites/default/files/documents/2020/06/national-immunisation-program-pneumococcal-vaccination-schedule-from-1-july-2020-clinical-advice-for-vaccination-providers.pdf">pneumococcal</a> and <a href="https://www.health.gov.au/topics/immunisation/vaccines/shingles-herpes-zoster-immunisation-service">shingles</a> vaccines. In general, most vaccines can be given in the same visit, but talk to your doctor about which ones you need. <h2>Are there side effects?</h2> All influenza vaccines can <a href="https://www.health.gov.au/topics/immunisation/vaccines/influenza-flu-vaccine">cause</a> a sore arm and sometimes more generalised symptoms such as fever and tiredness. These are expected and reflect the immune system reacting appropriately to the vaccine, and are mostly mild and short-term. These side effects are slightly more common in <a href="https://ncirs.org.au/sites/default/files/2021-02/Adjuvanted%20influenza%20vaccine%20vs%20standard%20dose%20influenza%20vaccine%20SoF%20EP%20E2D%20tables_26%20Feb%202021_Final.pdf">adjuvanted</a> and <a href="https://ncirs.org.au/sites/default/files/2022-05/HD%20vs%20sIV%20SoF%20EP%20E2D_March%202022_Final.pdf">high dose</a> vaccines. As with all medications and vaccines, allergic reactions such as anaphylaxis can occur after the flu vaccine. All vaccine providers are trained to recognise and respond to anaphylaxis. People with egg allergies should discuss this with their doctor, but in general, <a href="https://www.allergy.org.au/patients/food-allergy/egg-allergy-flu-vaccine">studies suggest</a> they can safely receive any (including egg-based) influenza vaccines. Serious side effects from the influenza vaccine, such as Guillain-Barré syndrome, a neurological complication, are very rare (one case per million people vaccinated). They are <a href="https://pubmed.ncbi.nlm.nih.gov/23810252/">thought</a> to be less common after influenza vaccination than after infection with influenza.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/226623/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/allen-cheng-94997">Allen Cheng</a>, Professor of Infectious Diseases, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to fall asleep without sleeping pills: 7 natural sleep aids that actually work

It’s 3am and you’re suddenly wide awake. Try these seven science-backed strategies to fall back to sleep fast. Give meditation a try As a mindfulness coach, I’m very aware of the day-to-day anxieties and worries that can interfere with a good night’s sleep. One of the most effective natural sleep aids is a quick meditation session to ease yourself out of those stresses. If you’ve never meditated before, you’ll likely find the meditation interrupted by thoughts flashing through your mind. It’s important for you to know that this isn’t a failure on your part, and that you aren’t doing anything wrong. Thinking is just what the brain does, as naturally as lungs take in air. The point is to be non-judgmental yet aware of your thoughts, bodily experiences and breath, moment by moment. Sleep better, feel better! <a href="https://gaiam.innovations.com.au/p/gaiam-wellness/rollers-resistance/27-72435-gaiam-strengthen-stretch-kit?affiliate=GAIAM6O" target="_blank" rel="noopener">This Blackout Sleep Mask from Gaiam</a> will help you feel well rested and renewed. Stop wanting to fall asleep It’s counterintuitive, isn’t it? Sometimes trying too hard to do something is the very thing that prevents us from achieving it – and that’s never more true than when it comes to falling asleep. Desperately wanting to sleep will only stoke anxieties that will further stress your brain, essentially feeding it the message that it’s not safe to sleep. Throw in those worries about your to-do list at work the following day, and the whole thing can snowball into a panic attack. Try letting go of that feeling that you absolutely must sleep now, and observe your own anxieties for what they are without judgment. When you stop looking at sleep as a goal, you’ll find it easier to fall asleep. Before you climb into bed, set aside 10-15 minutes to help relax your body and mind, with <a href="https://gaiam.innovations.com.au/p/gaiam-wellness/restore-massage/27-73353-gaiam-wellness-acupressure-neck-back-pillow?affiliate=GAIAM60" target="_blank" rel="noopener">this wellness acupressure neck and back pillow from Gaiam</a>. Start a journal If you find yourself struggling to fall asleep, pick up a pen and paper (not your phone!), and start writing: simply scribble down an account of what’s going on inside your head. Although there’s no “right” way to journal, you might start by listing the events of your day, and from there, how those events and encounters made you feel. Building this structured picture of your thoughts may help you see that the problem that’s keeping you up at night, and is likely less overwhelming than you thought. Why my insistence on a pen and paper? First off, studies show the simple motor action that’s involved in the act of handwriting has a calming effect. Secondly, the light emitted by laptops and phones isn’t conducive to falling asleep. Find yourself a "3am friend" Some of us are lucky to have a ‘3am friend’, that close confidant you can call up in the wee hours knowing that they won’t hold it against you in the morning. Although it’s great to have someone to talk to when you want to fall asleep, it’s important that the conversation doesn’t just rehash the anxieties that are preventing you from catching shut-eye in the first place. Rather than using the call to seek solutions for those issues, talk about things that calm your nerves, or even have them assist you in deep breathing. It may sound silly, but doing a series of deep, relaxing breaths can help you let go of the troubles that are keeping you wide awake. Take a warm shower Taking a warm shower not only relaxes your muscles and soothes minor aches and pains, but it also raises your core body temperature. As soon as you step out of the shower, your body starts working at lowering that temperature, which is something that normally happens when you’re falling asleep naturally. (That’s why we always feel the need for a blanket when we sleep, no matter how warm it is!) By kick-starting that temperature-lowering process, you’re tricking your body into falling asleep fast. Stretch yourself to sleep Anxiety keeping you up? Research suggests mild stretching can help take the edge off and relax muscles that have become stiff and sore after a long day. We’re not talking intricate yoga poses or acrobatics here, either: Simple stretches like an overhead arm stretch and bending over to touch your toes should do the trick. Ramp up the relaxation potential with a soundtrack of ambient noise at a volume that’s just barely audible. There are plenty of white noise apps that are free to download, but soft music can work as well (so long as there are no lyrics). Just remember, if you’re using an electronic device to play these sleep-promoting sounds, make sure it’s placed screen-down so you’re not distracted by the light it emits. Stretching is healing, and this <a href="https://gaiam.innovations.com.au/p/gaiam-wellness/rollers-resistance/27-72435-gaiam-strengthen-stretch-kit?affiliate=GAIAM60" target="_blank" rel="noopener">Strengthen and Stretch Kit from Gaiam</a> is a great way to start. An on-line workout is also included to get you started. Read (or listen!) to something new When you’re struggling with insomnia, it might be tempting to pull an old favourite off the bookshelf. In reality, it’s better to read or listen to an audio book that covers a topic on which you know absolutely nothing. New information, while taking attention away from the stressors that are keeping you up at night, gives your brain enough of a workout to make it tire more quickly than when it’s engaged with familiar subjects and concepts. Again, if it’s an audio book or podcast you’re listening to, make sure the light-emitting side of the device is face down to keep the room as dark as possible. Darkness and warmth play an essential part in the production and maintenance of melatonin, the hormone that plays the central role falling asleep.

Why do airlines charge so much for checked bags? This obscure rule helps explain why

<a href="https://theconversation.com/profiles/jay-l-zagorsky-152952">Jay L. Zagorsky</a>, <a href="https://theconversation.com/institutions/boston-university-898">Boston University</a> Five out of the six <a href="https://www.oag.com/blog/biggest-airlines-in-the-us">biggest U.S. airlines</a> have <a href="https://www.cnbc.com/2024/03/05/delta-is-the-latest-airline-to-raise-its-checked-bag-fee.html">raised their checked bag fees</a> since January 2024. Take American Airlines. In 2023, it cost US$30 to check a standard bag in with the airline; <a href="https://www.usatoday.com/story/travel/airline-news/2024/02/20/american-airlines-bag-fees-mileage-earning/72669245007/">today, as of March 2024, it costs $40</a> at a U.S. airport – a whopping 33% increase. As a <a href="https://www.bu.edu/questrom/">business school</a> <a href="https://www.bu.edu/questrom/profile/jay-zagorsky/">professor who studies travel</a>, I’m often asked why airlines alienate their customers with baggage fees instead of bundling all charges together. <a href="https://www.vox.com/2015/4/16/8431465/airlines-carry-on-bags">There are</a> <a href="https://www.usatoday.com/story/travel/columnist/2023/06/21/bag-fees-will-stay-a-while-cruising-altitude/70338849007/">many reasons</a>, but an important, often overlooked cause is buried in the U.S. tax code. <h2>A tax-law loophole</h2> Airlines pay the federal government <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D">7.5% of the ticket price</a> when <a href="https://www.pwc.com/us/en/services/tax/library/aircraft-club-nov-2023-air-transport-excise-tax-rates-for-2024.html">flying people domestically, alongside other fees</a>. The airlines dislike these charges, with their <a href="https://www.airlines.org/dataset/government-imposed-taxes-on-air-transportation/">trade association arguing</a> that they boost the cost to the consumer of a typical air ticket by around one-fifth. However, the U.S. Code of Federal Regulations <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D/section-49.4261-8">specifically excludes baggage</a> from the 7.5% transportation tax as long as “the charge is separable from the payment for the transportation of a person and is shown in the exact amount.” This means if an airline charges a combined $300 to fly you and a bag round-trip within the U.S., it owes $22.50 in tax. If the airline charges $220 to fly you plus separately charges $40 each way for the bag, then your total cost is the same — but the airline only owes the government $16.50 in taxes. Splitting out baggage charges saves the airline $6. Now $6 might not seem like much, but it can add up. Last year, passengers took <a href="https://www.transtats.bts.gov/Data_Elements.aspx?Data=1">more than 800 million trips on major airlines</a>. Even if only a fraction of them check their bags, that means large savings for the industry. How large? The government has <a href="https://www.bts.dot.gov/topics/airlines-and-airports/baggage-fees-airline-2023">tracked revenue from bag fees</a> for decades. In 2002, airlines charged passengers a total of $180 million to check bags, which worked out to around 33 cents per passenger. Today, as any flyer can attest, bag fees are a lot higher. Airlines collected over 40 times more money in bag fees last year than they did in 2002. When the full data is in for 2023, <a href="https://www.bts.dot.gov/baggage-fees">total bag fees</a> will likely top $7 billion, which is about $9 for the average domestic passenger. <a href="https://viewfromthewing.com/the-real-reason-airlines-charge-checked-bag-fees-and-its-not-what-you-think">By splitting out the cost of bags</a>, airlines avoided paying about half a billion dollars in taxes just last year. In the two decades since 2002, flyers paid a total of about $70 billion in bag fees. This means separately charging for bags saved airlines about $5 billion in taxes. <iframe id="88MYD" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/88MYD/2/" width="100%" height="400px" frameborder="0"></iframe> It seems clear to me that tax savings are one driver of the unbundling of baggage fees because of a quirk in the law. The U.S. government doesn’t apply the 7.5% tax to <a href="https://www.ecfr.gov/current/title-26/chapter-I/subchapter-D/part-49/subpart-D/section-49.4261-3">international flights that go more than 225 miles</a> beyond the nation’s borders. Instead, there are fixed <a href="https://www.airlines.org/dataset/government-imposed-taxes-on-air-transportation">international departure and arrival taxes</a>. This is why major airlines charge $35 to $40 <a href="https://www.aa.com/i18n/travel-info/baggage/checked-baggage-policy.jsp">for bags if you’re flying domestically</a>, but don’t charge a bag fee when you’re flying to Europe or Asia. <h2>Do travelers get anything for that money?</h2> This system raises an interesting question: Do baggage fees force airlines to be more careful with bags, since customers who pay more expect better service? To find out, I checked with the Bureau of Transportation Statistics, which has been <a href="https://www.bts.gov/content/mishandled-baggage-reports-filed-passengers-largest-us-air-carriersa">tracking lost luggage for decades</a>. For many years, it calculated the number of mishandled-baggage reports per thousand airline passengers. The government’s data showed mishandled bags peaked in 2007 with about seven reports of lost or damaged luggage for every thousand passengers. That means you could expect your luggage to go on a different trip than the one you are taking about once every 140 or so flights. By 2018, that estimate had fallen to once every 350 flights. In 2019, the government <a href="https://www.bts.gov/topics/airlines-and-airports/number-30a-technical-directive-mishandled-baggage-amended-effective-jan">changed how it tracks</a> mishandled bags, calculating figures based on the total number of bags checked, rather than the total number of passengers. The new data show about six bags per thousand checked get lost or damaged, which is less than 1% of checked bags. Unfortunately, the data doesn’t show improvement since 2019. Is there anything that you can do about higher bag fees? Complaining to politicians probably won’t help. In 2010, two senators <a href="https://www.nj.com/business/2010/04/us_senators_present_bill_to_ba.html">tried to ban bag fees</a>, and their bill went nowhere. Given that congressional action failed, there’s a simple way to avoid higher bag fees: <a href="https://www.cnn.com/travel/article/packing-expert-travel-world-handbag/index.html">travel light</a> and <a href="https://www.nytimes.com/2023/07/08/opinion/carry-on-packing-airlines-lost-luggage.html">don’t check any luggage</a>. It may sound tough not to have all your belongings when traveling, but it might be the best option as bag fees take off.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225857/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jay-l-zagorsky-152952">Jay L.

Why a one-cent stamp is set to sell for millions

An extremely rare stamp that was once bought for a measly one cent is set to sell for millions of dollars, breaking records at a US auction house. While to the untrained eye, the blue stamp seems like any old stamp, the 1868 one-cent Z-grill is actually the rarest stamp in America due to its unique history and rarity. On June 14th, the one-cent Z-grill will be put up for sale by Robert A. Siegel Auction Galleries, marking the first time the rare stamp has been on auction since 1998. Experts from the New York auction house say it could fetch $6 million to $7.5 million (AUD), which would make it the single most expensive US stamp ever sold. The reason for the extraordinary price comes down to the fact that out of the two known Z-grill stamp copies, the one up for auction is the only copy available for private purchase by collectors, while other historic copy is held at the New York Public Library. The Z-grill is unique due to its signature embossed paper, which was introduced to the US postal service after the Civil War to prevent stamps from being reused. Since 2005, the coveted stamp has belonged to billionaire investor and “bond king” Bill Gross. “It’s considered the trophy of collecting United States stamps,” said Charles Shreve, who has managed and built Gross’ extensive stamp collection for years and serves as director of international auctions at Robert A. Siegel Auction Galleries. “There’s only one. If you want to brag, that’s the stamp.” Mr Gross' entire collection is estimated to be worth $22.6 million to $30 million AUD. The top 100 stamps from the collection will be auctioned off on June 14th, while the remaining stamps will be sold on June 15th. “There’s multiple stamps that’ll bring $500,000 or $750,000 (USD) but the (one-cent) Z-grill is the star of the show,” Shreve said. “I just know some people who are lusting for it, and we want to try to get as many people interested in it as possible.” Image credits: Robert A.

Princess of Wales and King Charles: one in two people develop cancer during their lives – the diseases and treatments explained

<a href="https://theconversation.com/profiles/gavin-metcalf-1340598">Gavin Metcalf</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> The Princess of Wales released a <a href="https://x.com/KensingtonRoyal/status/1771235267837321694?s=20">moving video message</a> on March 22 to address speculation about her health. In it, the future queen disclosed that she’d been <a href="https://www.bbc.co.uk/news/health-68641710">diagnosed with cancer</a> following tests conducted after she underwent major abdominal surgery at a clinic in London in January. Catherine explained that she was undergoing “preventative chemotherapy” – but emphasised that her surgery had been successful, and that she was “well” and “getting stronger every day”. The message was the <a href="https://www.theguardian.com/uk-news/2024/mar/22/princess-kate-cancer-royal-family-health-annus-horribilis">second announcement</a> of a royal family cancer diagnosis in recent weeks. On February 5, Buckingham Palace <a href="https://www.royal.uk/a-statement-from-buckingham-palace-5Feb24">published a statement</a> that King Charles III had been diagnosed with an undisclosed form of <a href="https://www.bbc.co.uk/news/uk-68208157">cancer, unrelated</a> to the treatment he had been receiving for an enlarged prostate. <figure><iframe src="https://www.youtube.com/embed/3xzKooCaRXU?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> The statement said that he had begun “regular treatments”. The king postponed all public-facing duties during his treatment, but <a href="https://www.bbc.co.uk/news/uk-68213383">reportedly continued</a> with his “constitutional role as head of state, including completing paperwork and holding private meetings”. Cancer is the <a href="https://www.who.int/news-room/fact-sheets/detail/cancer">leading cause of death</a> worldwide. <a href="https://www.nhs.uk/conditions/cancer/#:%7E:text=The%20cancerous%20cells%20can%20invade,of%20cancer%20during%20their%20lifetime.">One in two</a> people will develop some form of cancer in their lifetime – so the condition will affect almost every family. However, many cancers can be cured if, as appears to be the case with the king, the condition is <a href="https://www.bbc.co.uk/news/uk-68213383">detected early</a> and treated effectively. <h2>What is cancer?</h2> Our bodies are made up of more than 100 billion cells, and cancer typically starts with changes in a small group of cells – or even a single one. We have different cell types depending upon where in the body they are and the function that the cell has. The size, amount and function of each of these cells is normally tightly regulated by genes – groups of codes held within our DNA – that instruct cells how to grow and divide. However, changes (mutations) to DNA can alter the way cells grow and multiply – often forming a lump, or solid tumour. Cancers can also develop in blood cells, such as white blood cell cancer which is known as leukaemia. This type of cancer does not form solid tumours; instead, the cancer builds up in the blood or sometimes the marrow in the core of bones, where blood cells are produced. In all, there are <a href="https://www.cancerresearchuk.org/about-cancer/what-is-cancer/how-cancer-starts/types-of-cancer#:%7E:text=For%20example%2C%20nerves%20and%20muscles,of%20cell%20they%20start%20in.">more than 200</a> types of cancer, but all start with mutations in the DNA contained within each and every cell. <h2>What exactly are mutations?</h2> Think of your DNA as a big recipe book, and your genes as individual recipes for making different dishes. Mutations are smudges or missing words from this recipe that can result in key ingredients not being added into the mix. <figure><iframe src="https://www.youtube.com/embed/8BJ8_5Gyhg8?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Regardless of the type of cancer or the cells from which it develops, mutations in our genes can result in a cell no longer understanding its instructions. These mutations can happen by chance when dividing, but can also be the result of lifestyle choices such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6141049/">smoking</a>, <a href="https://www.ndph.ox.ac.uk/news/new-genetic-study-confirms-that-alcohol-is-a-direct-cause-of-cancer#:%7E:text=These%20mutations%20both%20disrupt%20the,aldehyde%20dehydrogenase%202%20(ALDH2).">drinking</a>, and <a href="https://www.cancer.gov/about-cancer/causes-prevention/risk/obesity/physical-activity-fact-sheet">inactivity</a>. Research has found that in order for a normal cell to turn into a cancerous cell, anywhere from <a href="https://www.sanger.ac.uk/news_item/1-10-mutations-are-needed-drive-cancer-scientists-find/">one to ten different mutations</a> are normally required. <h2>How is cancer treated?</h2> Treatment options for cancer depend on a variety of factors, including where your cancer is, how large it is, and whether it has spread to other parts of the body. The main treatments for cancer include surgery, chemotherapy, and radiotherapy. Chemotherapy uses drugs to target and kill cells that are rapidly dividing in our bodies. This approach is effective at targeting fast-growing cells in various cancers – but also has negative side effects. It also targets healthy cells that rapidly divide, such as hair and the cells lining our digestive system. This can lead to commonly reported <a href="https://www.nhs.uk/conditions/chemotherapy/side-effects/">side-effects</a> such as hair loss, nausea and diarrhoea. <a href="https://www.cancerresearchuk.org/about-cancer/treatment/chemotherapy?gad_source=1&gclid=Cj0KCQjw-_mvBhDwARIsAA-Q0Q6tyQxTuBzU7vVD7SHjQ5dF-fRdqnL7S74-k5LXyTqODydsrPfJVsoaAkgyEALw_wcB&gclsrc=aw.ds">Chemotherapy</a> can be used both preventatively – as in the case of the princess – and therapeutically. <figure><iframe src="https://www.youtube.com/embed/FkZn5u3MIiY?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Preventative chemotherapy, also known as <a href="https://www.cancer.gov/publications/dictionaries/cancer-terms/def/adjuvant-therapy">adjuvant chemotherapy</a>, is given after surgery or other primary treatments to eliminate any remaining cancer cells in the body. It aims to reduce the risk of the cancer returning (known as recurrence). Therapeutic chemotherapy is used as a treatment option for cancer that has spread or is well established, such as advanced-stage cancers. <a href="https://www.cancerresearchuk.org/about-cancer/treatment/surgery/about">Surgery</a> involves the physical removal of cancerous tissues as well as nearby lymph nodes – small glands which act as filters in your body that cancers can spread through – to eliminate the tumour. Surgery is often used to remove localised cancers that haven’t spread throughout the body. <a href="https://www.cancerresearchuk.org/about-cancer/treatment/radiotherapy">Radiotherapy</a> uses high-energy radiation beams that are able to target specific areas where tumour cells are located to destroy or shrink the tumour. Radiotherapy can be applied externally or internally. Chemotherapy, surgery, and radiotherapy are often combined in cancer treatment to improve outcomes for patients. Thanks to developments in cancer research over the last 50 years, survival rates have improved greatly – although the rate of improvement has <a href="https://news.cancerresearchuk.org/2024/02/02/world-cancer-day-2024/#:%7E:text=Improvements%20in%20cancer%20survival%20have%20slowed%20in%20recent%20years&text=Survival%20increased%20three%20to%20five,consistently%20lags%20behind%20comparable%20countries.">slowed recently</a>. Cancer survival depends on various factors such as age – people under 40 have a <a href="https://www.cancer.gov/about-cancer/causes-prevention/risk/age">greater chance</a> of survival – overall health and fitness, as well as family history. <h2>What you should do</h2> Particular changes in your body or warning symptoms could indicate the presence of cancer.
