People in the world’s ‘blue zones’ live longer – their diet could hold the key to why

<a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Ageing is an inevitable part of life, which may explain our <a href="https://time.com/4672969/why-do-people-want-to-live-so-long/">strong fascination</a> with the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2726954">quest for longevity</a>. The allure of <a href="https://pubmed.ncbi.nlm.nih.gov/26566891/">eternal youth</a> drives a <a href="https://www.alliedmarketresearch.com/longevity-and-anti-senescence-therapy-market-A14010">multi-billion pound industry</a> ranging from anti-ageing products, supplements and <a href="https://www.everydayhealth.com/diet-nutrition/longevity-diet">diets</a> for those hoping to extend their lifespan. f you look back to the turn of the 20th century, average life expectancy in the UK was around 46 years. Today, it’s closer to <a href="https://population.un.org/wpp/">82 years</a>. We are in fact <a href="https://pubmed.ncbi.nlm.nih.gov/27706136/">living longer than ever before</a>, possibly due to medical advancements and improved <a href="https://www.health.org.uk/publications/reports/mortality-and-life-expectancy-trends-in-the-uk">living and working conditions</a>. But living longer has also come at a price. We’re now seeing higher rates of <a href="https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/ghe-leading-causes-of-death">chronic and degenerative diseases</a> – with heart disease consistently topping the list. So while we’re fascinated by what may help us live longer, maybe we should be more interested in being healthier for longer. Improving our “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4632858/">healthy life expectancy</a>” remains a global challenge. Interestingly, certain locations around the world have been discovered where there are a high proportion of centenarians who display remarkable physical and mental health. The <a href="https://pubmed.ncbi.nlm.nih.gov/15489066/">AKEA study of Sardinia, Italy</a>, as example, identified a “blue zone” (named because it was marked with blue pen), where there was a higher number of locals living in the central-eastern mountainous areas who had reached their 100th birthday compared with the wider Sardinian community. This longevity hotspot has since been expanded, and now includes several other areas around the world which also have greater numbers of longer-living, healthy people. Alongside Sardinia, these blue zones are now <a href="https://www.netflix.com/gb/title/81214929">popularly recognised</a> as: Ikaria, Greece; Okinawa, Japan; Nicoya, Costa Rica; and Loma Linda, California. Other than their long lifespans, people living in these zones also appear to share certain other commonalities, which centre around being <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3874460">part of a community</a>, having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224996/">life purpose</a>, eating <a href="https://pubmed.ncbi.nlm.nih.gov/33514872/">nutritious, healthy foods</a>, keeping <a href="https://www.nature.com/articles/s41398-021-01735-7">stress levels</a> low and undertaking purposeful daily <a href="https://pubmed.ncbi.nlm.nih.gov/30202288/">exercise or physical tasks</a>. Their longevity could also relate to their <a href="https://pubmed.ncbi.nlm.nih.gov/9010380/">environment</a>, being mostly rural (or less polluted), or because of <a href="https://pubmed.ncbi.nlm.nih.gov/22253498/">specific longevity genes</a>. However, studies indicate genetics may only account for <a href="https://pubmed.ncbi.nlm.nih.gov/8786073">around 20-25% of longevity</a> – meaning a person’s lifespan is a complex interaction between lifestyle and genetic factors, which contribute to a long and healthy life. <h2>Is the secret in our diet?</h2> When it comes to diet, each blue zone has its own approach – so one specific food or nutrient does not explain the remarkable longevity observed. But interestingly, a diet rich in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662288">plant foods</a> (such as locally-grown vegetables, fruits and legumes) does appear to be reasonably consistent across these zones. For instance, the Seventh-day Adventists of Loma Linda are <a href="https://pubmed.ncbi.nlm.nih.gov/10641813/">predominately vegetarian</a>. For centenarians in Okinawa, <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">high intakes of flavonoids</a> (a chemical compound typically found in plants) from purple sweet potatoes, soy and vegetables, have been linked with <a href="https://pubmed.ncbi.nlm.nih.gov/11710359/">better cardiovascular health</a> – including lower cholesterol levels and lower incidences of stroke and heart disease. In Nicoya, consumption of locally produced rice and beans has been associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34444746/">longer telomere length</a>. Telomeres are the structural part at the end of our chromosomes which protect our genetic material. Our telomeres get shorter each time a cell divides – so get progressively shorter as we age. Certain <a href="https://pubmed.ncbi.nlm.nih.gov/21102320/">lifestyle factors</a> (such as smoking and poor diet) can also shorten telomere length. It’s thought that telomere length acts as a <a href="https://pubmed.ncbi.nlm.nih.gov/31728493/">biomarker of ageing</a> – so having longer telomeres could, in part, be linked with longevity. But a plant-based diet isn’t the only secret. In Sardinia, for example, meat and fish is consumed in moderation in addition to locally grown vegetables and <a href="https://journalofethnicfoods.biomedcentral.com/articles/10.1186/s42779-022-00152-5">traditional foods</a> such as acorn breads, pane carasau (a sourdough flatbread), honey and soft cheeses. Also observed in several blue zone areas is the inclusion of <a href="https://www.jacc.org/doi/10.1016/j.jacc.2021.10.041">olive oil</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/33669360/">wine</a> (in moderation – around 1-2 glasses a day), as well as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830687/">tea</a>. All of these contain powerful antioxidants which may help <a href="https://ncbi.nlm.nih.gov/pmc/articles/PMC10049696/">protect our cells</a> from damage <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6273542/">as we age</a>. Perhaps then, it’s a combination of the protective effects of various nutrients in the diets of these centenarians, which explains their exceptional longevity. Another striking observation from these longevity hot spots is that meals are typically <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7232892">freshly prepared at home</a>. Traditional blue zone diets also don’t appear to contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6538973/">ultra-processed foods</a>, fast foods or sugary drinks which may <a href="https://pubmed.ncbi.nlm.nih.gov/32330232/">accelerate ageing</a>. So maybe it’s just as important to consider what these longer-living populations are not doing, as much as what they are doing. There also appears to be a pattern of eating until 80% full (in other words partial <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9036399/">caloric reduction</a>. This could be important in also supporting how our cells deal with damage as we age, which could mean a longer life. Many of the factors making up these blue zone diets – primarily plant-based and natural whole foods – are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/35706591/">lower risk of chronic diseases</a> such as <a href="https://pubmed.ncbi.nlm.nih.gov/28728684/">heart disease</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/37589638/">cancer</a>. Not only could such diets contribute to a <a href="https://pubmed.ncbi.nlm.nih.gov/37836577/">longer, healthier life</a>, but could support a more <a href="https://pubmed.ncbi.nlm.nih.gov/33397404/">diverse gut microbiome</a>, which is also associated with healthy ageing. Perhaps then we can learn something from these remarkable centenarians. While diet is only one part of the bigger picture when it comes to longevity, it’s an area we can do something about. In fact, it might just be at the heart of improving not only the quality of our health, but the quality of how we age.<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/221463/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, Professor of Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, PhD Candidate in Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, Senior Lecturer in Public Health and Nutrition, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The key decision that led to cruise passengers being abandoned by ship

A group of travellers, including two Australians, have been left stranded in Africa after their cruise ship allegedly refused to let them board the ship after a day trip. Eight passengers were among the many cruisers who disembarked the Norwegian Dawn at São Tomé and Príncipe, an island nation of 220,000 people off the west coast of Africa in the Gulf of Guinea, last Wednesday. The group of eight passengers took off on a private day tour, that reportedly wasn't organised through the cruise company. Things turned sour when the group were delayed on their day trip, with their tour operator allegedly connecting with the captain to tell the cruise the eight passengers would arrive later than their 3pm curfew. When the group arrived to the port, the ship was still anchored, but American couple Jill and Jay Campbell said the captain allegedly refused to let them on board. According to cruise ship lawyer Spencer Aonfeld, the group's big mistake was not booking the tour through the cruise company, as private tours come with a huge risk. Weighing into the drama on TikTok, Mr Aonfeld said, “Eight passengers were left behind when their cruise ship left them because they were delayed in an excursion apparently conducted without buying it directly through Norwegian." “These passengers include elderly passengers, one apparently a paraplegic, one has a heart condition, they don't have their medication, money, passports, cell phones and other things — they’re just left behind." “That unfortunately, according to Norwegian and me is, one of the consequences you pay when you buy your excursions from someone other than the cruise line." “Now they’re left there having to come up with the means to travel back to the next port or home and forfeit the remaining potion of their cruise. Imagine trying to do that in Africa without a passport, money or medication — we wish them the very best.” In order to rejoin the cruise and be reunited with their valuables, the group is now trekking to a port in Senegal, where the cruise is set to dock on Tuesday. In a statement, Norwegian Cruise Lines said it was “in communication with the guests,” and was providing them with “additional information” to rejoin the cruise. “While this is a very unfortunate situation, guests are responsible for ensuring they return to the ship at the published time, which is communicated broadly over the ship’s intercom, in the daily communication and posted just before exiting the vessel,” NCL said in a statement. The company said it was “working closely with the local authorities” on how the guests might re-join the ship. Image credits: Getty Images / WRAL North Carolina

Iconic Victorian Sphinx Hotel up for sale

The iconic Sphinx hotel is in Geelong, Victoria is up for sale for the first time in over 50 years. The Ramia family, who built a 14m-high replica sphinx on the roof of their pub, are looking to sell their property after 53 years of ownership. “We’ve got to the stage where we all want to do our own thing and it’s quite a large family,” George Ramia, the owner of the hotel said. “We’re up to nearly 53 years here and I think we’re getting a bit tired. “I started work here when I was about 14. I recall those days I wasn’t allowed in the pub but I used to do all the beer lines. “Johnny O’Keeffe used to play a lot and he always asked me to play pool, and I was a pretty good player because it’s all I was allowed to do.” Ramia who started working at the former Golf View Hotel when he was 14, saw the venue change throughout the decades from a home for live music to a bistro and recently renovated sports bar. He also saw the venue grow in popularity, after a period of financial difficulties, when the pub was remodelled with the 14m-high Sphinx on the roof, completed with Egyptian-style motifs including hieroglyphics and even a mock gold pharaoh’s tomb in the 1990s. The pub continues to host live bands and events, including the Geelong Elvis Festival. The Sphinx Hotel is positioned on a 15,000sq m freehold land parcel, with 16-rooms of various configurations, with approvals in place to develop a further 24 rooms. It also features 67 electronic gambling machines, multiple bar areas and function rooms, an outdoor beer garden, a TAB and a recently renovated sports bar. The sale of the property also include the drive-through bottle shop and a licence capacity for 1010 patrons. The hotel is available as either a new long-term lease or a freehold going concern, which is currently being managed by CBRE Hotels’ senior director Scott Callow. “Geelong’s Sphinx Hotel presents a compelling investment opportunity in the thriving gaming and entertainment industry,” the CBRE Hotels’ senior director said. “We anticipate strong interest from a range of investment segments seeking to gain a significant foothold in Victoria’s tightly held gaming market.” Images: Sphinx Hotel / Facebook

The secret witness who could be the key to the Madeleine McCann case

A secret witness to a disturbing comment made by the main suspect in the Madeleine McCann case could be the key to seeing him charged. Madeleine McCann was three years old when she went missing on a family trip to Portugal in 2007, and has not been seen since. Christian Brueckner, a convicted rapist and paedophile, has long been named the prime suspect in Maddie's abduction, and is set to stand trial on Friday for a series of charges, none of while relate to the McCann case. Now, almost seventeen years since her disappearance, a secret witness has come forward about a disturbing comment Brueckner a year after Maddie's abduction. Helge Busching, a former friend of Brueckner, has revealed a chilling conversation he had with his former friend after they ran into each other at a music festival. Busching, who is currently in police protection, claims Brueckner told him Madeleine was taken without anyone noticing because she didn't make a sound. "He said she didn't scream. 'She didn't scream', that is what Brueckner said and then I looked at Mr Brueckner and thought 'what are you telling me now?'" said Busching on <a href="https://9now.nine.com.au/60-minutes/the-secret-witness-who-could-break-open-the-madeleine-mccann-case/3a383ca7-758a-4b46-a288-8f911ee942e5" target="_blank" rel="noopener">60 Minutes</a>. <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/C3NDFgEPudr/?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/C3NDFgEPudr/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by 60 Minutes Australia (@60minutes9)</a> </div> </blockquote> In the wake of Busching's comments, the police prosecutor in Brueckner's case remains adamant he is behind the high-profile disappearance of Maddie. "We have evidence and we come to the conclusion that Madeleine McCann is dead and Christian B murdered her," says Hans Christian Wolters. With the 46-year-old currently in jail and facing convictions for several counts of rape and sexual assault, Wolters has the luxury of time to pursue all leads, no matter how small, to build a watertight case against the suspect. He said, "We have only one chance and we want to go to court with the best result we could get. So we decided to investigate as much as we can and if it takes much more time than normal investigations, it's the price for the best result." Image credits: Getty Images / 60 Minutes

Should we still be using RATs to test for COVID? 4 key questions answered

<a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> We’re currently navigating <a href="https://www.thenewdaily.com.au/life/health/2023/11/15/covid-australia-eighth-wave">an eighth wave</a> of <a href="https://theconversation.com/were-in-a-new-covid-wave-what-can-we-expect-this-time-216820">COVID infections</a> in Australia. However the threat COVID poses to us is significantly less than it has ever been, thanks to immunity we’ve acquired through <a href="https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(22)00801-5/fulltext">a combination</a> of prior infection and vaccination. That said, COVID is by no means behind us. The threat of severe illness remains higher for many people, and we’re all potentially at risk of developing <a href="https://www.health.gov.au/topics/covid-19/long-covid">long COVID</a>. While many people appear to be doing fewer rapid antigen tests (RATs) than they used to – if any at all – with rising cases, and as we head towards the festive season, testing continues to be important. So what do you need to know about testing in this wave? Here are four key questions answered. <h2>1. When should I do a RAT?</h2> There are a few situations where determining your COVID status is important to inform your actions, particularly during an uptick in infections. With more circulating virus, your index of suspicion that you have COVID if you’re experiencing cold-like symptoms should be higher. RATs work best when they’re used to confirm whether you have COVID when you <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/how-testing-works-covid-19">have respiratory symptoms</a> and are infectious. So the primary use of RATs should be to determine your COVID status when you’re sick. A positive test should prompt you to isolate, and if you’re eligible, to seek antivirals. Testing might also be worthwhile if you’ve come into contact with someone with COVID but you haven’t developed symptoms. If you find you have in fact contracted the virus, you can take steps to avoid spreading it to other people (you can infect others even <a href="https://www.healthline.com/health/what-is-asymptomatic-covid#prevalence">when you’re asymptomatic</a>). This is especially important if you’re going to be socialising in large groups or in contact with people who are vulnerable. Another situation in which to consider testing, particularly at this time of year, is before attending large social gatherings. While the reliability of a RAT is never perfect, do the test as close to the event as possible, because your disease status <a href="https://www.businessinsider.com/omicron-rapid-test-hour-before-party-not-day-before-expert-2021-12">can change quickly</a>. <h2>2. Should I test multiple times?</h2> Yes. RATs are not as sensitive as PCR tests, which is the trade-off we make for being able to do this test at home and <a href="https://www.wsj.com/articles/public-health-officials-pursue-covid-19-tests-that-trade-precision-for-speed-11599562800">getting a rapid result</a>. This means that while if you test positive with a RAT you can be very confident you have COVID, if you test negative, you cannot be as confident that you don’t have COVID. That is, the test may give you a false negative result. Although RATs from different manufacturers have different accuracies, all RATs approved by Australia’s Therapeutic Goods Administration must have a sensitivity of <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/covid-19-rapid-antigen-self-tests-home-use/covid-19-rapid-antigen-self-tests-are-approved-australia#:%7E:text=For%20rapid%20antigen%20tests%2C%20this,specificity%20of%20at%20least%2098%25.">at least 80%</a>. The way to increase your confidence in a negative result is to do multiple RATs serially – each negative test increases the confidence you can have that you don’t have COVID. If you have symptoms and have tested negative after your first RAT, <a href="https://www.fda.gov/medical-devices/safety-communications/home-covid-19-antigen-tests-take-steps-reduce-your-risk-false-negative-results-fda-safety">the advice</a> is to repeat the test after 48 hours, and potentially a third time after another 48 hours if the second test is also negative. <h2>3. Do RATs detect the latest variants?</h2> Since RATs <a href="https://www.healthdirect.gov.au/covid-19/testing#:%7E:text=Rapid%20antigen%20tests%2C%20or%20RATs,of%20proteins%20of%20the%20virus.">detect particular surface proteins</a> on SARS-CoV-2 (the virus that causes COVID), it’s theoretically possible that as the virus evolves, the reliability of these tests may be affected. However, RATs were designed to detect a part of the virus that is not as likely to mutate, so the hope is these tests <a href="https://www.health.com/do-covid-tests-work-new-variants-7967102">will continue to hold up</a> as SARS-CoV-2 evolves. The performance of RATs is continually being assessed by manufacturers. So far, there’s been no change reported in the ability of these tests to <a href="https://www.ama.com.au/articles/tga-updated-advice-rats-nearing-expiry-and-rats-efficacy-current-strains#:%7E:text=The%20TGA%20has%20received%20evidence,19%20RAT%20post%2Dmarket%20review.">detect the latest variants</a>. <h2>4. Can I rely on expired RATs?</h2> At this point in the pandemic, you might have a few expired tests at the back of your cupboard. Technically the most appropriate advice is to say you should never use a diagnostic test <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/covid-19-rapid-antigen-self-tests-home-use/covid-19-rapid-antigen-self-tests-are-approved-australia">past its expiry date</a>. As a general principle the performance of a test cannot be guaranteed beyond this date. The risk is that over time the components of the RAT degrade and if you use a test that’s not working optimally, it’s more likely to indicate <a href="https://www.health.com/can-you-use-expired-covid-test-6827970">you don’t have COVID</a> when you actually do, which may have consequences. However, as for all things COVID, the answer is not so black and white. Since these tests were new when they were introduced earlier in the pandemic, manufacturers didn’t have specific data on their performance over time, and so the expiry dates given were necessarily conservative. It’s likely these tests will work beyond the expiry dates on the packet, but just how long and how well they work is a bit of an unknown, so we need to be cautious. The other thing to consider is ensuring you store RATs correctly. Storage instructions should be found on the packet, but the key issue is making sure they’re not exposed to extreme temperatures. In particular, <a href="https://7news.com.au/lifestyle/health-wellbeing/how-to-properly-store-your-at-home-covid-19-rapid-antigen-tests-c-5465412">high temperatures</a> may damage the chemicals in the test which may reduce its sensitivity. <h2>The path from here</h2> Regular upticks in COVID cases are something we’re going to have to get used to. At these times, we should all be a bit more cautious about looking after ourselves and others as we go about our lives. What this looks like will vary for different people depending on their personal circumstances. However, being up to date with <a href="https://theconversation.com/what-are-the-new-covid-booster-vaccines-can-i-get-one-do-they-work-are-they-safe-217804">booster vaccinations</a>, having a plan for <a href="https://www.health.gov.au/topics/covid-19/oral-treatments">accessing antivirals</a> if you’re eligible, <a href="https://theconversation.com/with-covid-surging-should-i-wear-a-mask-217902">wearing masks</a> in high-risk settings and testing all continue to play an important role in responding to COVID.<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/218016/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, Associate Professor, Epidemiology, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

“Bed of the future” baffles travellers

People usually don't get confused about how to use a bed, but Virgin Hotel's latest addition has gone viral for just that. The Richard Branson bed, has been named the "hotel bed of the future" and it looks like any other bed, aside from the seat-like nooks attached to the corners. "We're very confused by this thing on the edge of my bed," TikTok user Danielle said in the viral video, which has racked up over 3 million views. "It's not a chair, and it doesn't swivel out," she explained. Danielle then proceeds to come up with a few theories about the feature's function. "It's so you don't bump your knee when you're getting up or going back to bed after going to the bathroom," she said. "Or, we're wondering if it's so you can sit and chat with your friends." Other users were quick to comment and here are a few of their hilarious responses: "That's where you stack your laundry when you don't feel like putting it away," one person wrote. "I thought this was so your dog could have a comfy spot to lay," another commented. "Without getting too graphic … the possibilities are endless," added a third. <div class="embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; color: #323338; font-family: Figtree, Roboto, 'Noto Sans Hebrew', 'Noto Kufi Arabic', 'Noto Sans JP', sans-serif; background-color: #ffffff; outline: none !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border-width: 0px; border-style: initial; vertical-align: baseline; width: 580px; max-width: 100%; outline: none !important;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7296702849298337066&display_name=tiktok&url=https%3A%2F%2Fwww.tiktok.com%2F%40danielle_carolan%2Fvideo%2F7296702849298337066%3Fis_from_webapp%3D1%26sender_device%3Dpc%26web_id%3D7142332295764346370&image=https%3A%2F%2Fp19-sign.tiktokcdn-us.com%2Ftos-useast5-p-0068-tx%2F53b6a23d5bbd4af1a1907e2073c2b818_1698896032%7Etplv-dmt-logom%3Atos-useast5-i-0068-tx%2Fo4IRiSlAxEom0dpDDDEQQQFBJAAC3gffEGEA6J.image%3Fx-expires%3D1699570800%26x-signature%3DIMlG9WO44PlRm5CNyVIyayR4AxM%253D&key=59e3ae3acaa649a5a98672932445e203&type=text%2Fhtml&schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> One commenter came to the rescue with the answers everyone was looking for, and confirmed that Danielle's second guess was right, and told her to look up the "Richard Branson lounge bed". The bed itself was patented by Virgin Hotels and features two "cubby holes" which allow three people to sit comfortably on the bed and socialise or do their own thing. "Everybody has a cubby hole where they can sit and talk and still work with devices," Virgin Hotels CEO Raul Leal explained when the bed was first introduced in 2015. Images: TikTok

"This is insane": Woman's intense hotel safety routine divides audiences

A woman has gone viral for the elaborate routine she undergoes every time she checks into a new hotel room. Victoria posted a TikTok of her intense seven-step routine that she undertakes when staying in a hotel, with the video quickly racking up over 14 million views. In the now-viral clip, Victoria starts off by putting the “Do Not Disturb” sign on the doorknob and locking it from the inside. Then, she blocks the peephole with a tissue, jams a washcloth into the deadbolt to "close the gap" and rolls up a bath towel behind the handle to stop anyone opening the door. She also positioned an ironing board against the door to stop it from being able to open, and then used a clothes hanger to clip everything together. After going through the seven step routine, Victoria's comment section was flooded with messages as the video prompted a mixed response. "By the time I do all that, it's morning again," one user wrote, while another simply said, "This is insane." While many of the comments were quick to judge how extensive the safety routine is, others shared their own different security preferences. "I take two portable locks, and a mini camera that links to my phone for when I'm out," one said. However, one person pointed out that Victoria's set-up was a bit of a hazard, saying, "And now imagine trying to get out of that in the dark in a fire in the middle of the night." Another said they had "never stayed in hotels where I felt so unsafe," adding, "Is it an American thing? I am genuinely curious." Image credits: TikTok

Eight key questions about lab-grown meat

<div class="copy"> It’s been around for a decade now — but <a href="https://cosmosmagazine.com/podcast/lab-grown-meat/" target="_blank" rel="noreferrer noopener">cultured meat</a> still faces some huge hurdles. On 5 August, it will be ten years since the world was introduced to <a href="https://www.bbc.com/news/science-environment-23576143" target="_blank" rel="noreferrer noopener">the first lab-grown burger</a>. A decade after its arrival, biotechnologist Professor Paul Wood answers eight key questions about cultured meat. <h2>What is lab-grown meat?</h2> Cultured meat, also colloquially referred to as lab-grown meat, is <a href="https://academic.oup.com/af/article/13/2/68/7123477" target="_blank" rel="noreferrer noopener">the concept</a> of taking a biopsy from a living animal, selecting an individual cell type and growing these cells in large scale <a href="https://journals.physiology.org/doi/abs/10.1152/ajpcell.00408.2022" target="_blank" rel="noreferrer noopener">bioreactors</a>. Technically, it’s a viable alternative to growing an animal to maturity before harvesting meat from its carcass. Multiple cell types can be used from animals, such as muscle, fat or <a href="https://www.genome.gov/genetics-glossary/Fibroblast" target="_blank" rel="noreferrer noopener">fibroblasts</a>. The initial stage of cell selection requires the <a href="https://www.sciencedirect.com/science/article/pii/B9780123745538002537" target="_blank" rel="noreferrer noopener">creation of a cell line</a> which will grow continuously in a selective culture medium. <h2>How long has it been around?</h2> The technology for the culture of cells in laboratories has been used for many decades to produce drugs like <a href="https://www.cancer.gov/about-cancer/treatment/types/immunotherapy/monoclonal-antibodies" target="_blank" rel="noreferrer noopener">monoclonal antibodies</a> or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7161866/" target="_blank" rel="noreferrer noopener">viral vaccines</a>. The difference with cultured meat is the cells themselves are used to produce edible products rather than used as production systems for monoclonals or viral antigens. Cultured meat was first introduced back in 2013 with <a href="https://www.bbc.com/news/science-environment-23576143" target="_blank" rel="noreferrer noopener">the unveiling of the world’s first lab-grown burger</a>, which cost a whopping USD$330,000 to produce. The first commercial cultured meat product was <a href="https://www.bbc.com/news/business-55155741" target="_blank" rel="noreferrer noopener">a chicken nugget licensed in Singapore</a> in 2020. <a href="https://www.scientificamerican.com/article/lab-grown-meat-approved-for-sale-what-you-need-to-know/" target="_blank" rel="noreferrer noopener">In June 2023</a>, the US Department of Agriculture granted two companies — Upside Foods and Good Meat — licences to sell chicken-based products. Significant excitement ensued in the food industry with <a href="https://www.liebertpub.com/doi/abs/10.1089/ind.2021.29240.ctu?journalCode=ind" target="_blank" rel="noreferrer noopener">predictions</a> that cultured meat will transform the meat industry by 2030. <h2>Is lab-grown meat commercially viable?</h2> Currently <a href="https://gfi.org/resource/cultivated-meat-eggs-and-dairy-state-of-the-industry-report/" target="_blank" rel="noreferrer noopener">around USD$3 billion</a> has been invested in over 150 companies working on beef, chicken, pork, lamb and exotic cell-based products. <a href="https://www.theatlantic.com/health/archive/2023/03/woolly-mammoth-meatball-stunt-food-marketing/673578/" target="_blank" rel="noreferrer noopener">Woolly mammoth meatball</a> anyone? Upside Foods has launched its <a href="https://edition.cnn.com/2023/07/01/business/lab-grown-chicken-san-francisco/index.html" target="_blank" rel="noreferrer noopener">new cell-based chicken product in a Michelin star restaurant</a>, but it is only available one night a month and the price has not been disclosed. Commercial success will require significant scaling in production, <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/bit.27848" target="_blank" rel="noreferrer noopener">cost reductions</a> and consumer acceptance, or these products will be confined to niche markets for wealthy consumers. Cultured meat is unlikely to be the solution for the <a href="https://www.mdpi.com/2304-8158/6/7/53" target="_blank" rel="noreferrer noopener">increasing protein needs of developing nations</a>. The <a href="https://academic.oup.com/af/article/13/2/68/7123477" target="_blank" rel="noreferrer noopener">technical challenges</a> involve scaling up cell growth in over 10,000 litre fermentation vessels, while significantly reducing the cost of cell-culture media, the capital cost of equipment and the operating cost of high-quality sterile biocontainment facilities. It has been estimated that the cost of production of cultured meat <a href="https://cedelft.eu/publications/tea-of-cultivated-meat/" target="_blank" rel="noreferrer noopener">must be reduced by over 1,000-fold</a> to match that of conventional meat production. Proponents of cultured meat like to quote the concept of <a href="https://ourworldindata.org/moores-law" target="_blank" rel="noreferrer noopener">Moore’s law</a> that predicts that the cost of all new technology will be significantly reduced with time. However this law has never been applied to a biological system that has innate growth limits. <h2>Is it good for you — and does it taste okay?</h2> Currently <a href="https://www.nature.com/articles/s41467-020-20061-y" target="_blank" rel="noreferrer noopener">all cultured meats are hybrid or blended products</a>, in which the harvested cell paste — the meat component — is combined with plant-based materials, plus vitamins and minerals to produce burgers, meatballs, sausages and dumplings. Yes, you have to add the vitamins in, and no, you can’t make a steak with it yet. From a commercial perspective this is important, as cultured meat products will compete in the commodity meat market. Cultured meat does not produce a three-dimensional steak with multiple cell types and complex taste and texture. However, <a href="https://www.forbes.com/sites/lanabandoim/2021/02/12/worlds-first-3d-bioprinted-and-cultivated-ribeye-steak-is-revealed/?sh=4b6baf0a4781" target="_blank" rel="noreferrer noopener">there are companies</a> aiming to develop whole cuts of meat using 3D printing and bioengineering technology. <h2>What is the motivation to produce cell-cultured meat?</h2> The drivers for cultured meat are that <a href="https://www.abc.net.au/news/rural/2018-05-06/vegan-alternative-plant-based-meat-grown-in-lab/9726436" target="_blank" rel="noreferrer noopener">animals are not slaughtered</a>, there can be less land and water usage and less greenhouse gases are produced than conventional meat production, particularly from ruminants like cattle and sheep. A lower manufacturing footprint is a terrific plus. And not killing animals is something a lot of people advocate for, but until cultured meat has been scaled significantly, it won’t be known if it’s really better for the planet or for humans. The <a href="https://www.foodnavigator-usa.com/Article/2022/04/21/cultivated-meat-upside-foods-closes-400m-series-c-round-to-support-commercial-scale-plant-with-production-capacity-of-tens-of-millions-of-pounds" target="_blank" rel="noreferrer noopener">largest facility built so far</a> is a pilot plant in the USA that aims to produce around 1,000 pounds (approximately 450 kilograms) of product per week, which is equivalent to the dressed weight of three carcasses — what a single suburban butcher processes in one day. <h2>Will it be expensive to buy?</h2> The taste and texture of food is critical to consumers — but so is value for money. So, it’s not surprising <a href="https://www.visualcapitalist.com/cp/mapped-meat-consumption-by-country-and-type/" target="_blank" rel="noreferrer noopener">chicken is the dominant choice of meat</a> currently. With high-end lab-grown meat products, both taste and texture can most likely be matched, and with supplementation with vitamins like B12 it should be possible to make cultured meat nutritionally equivalent to its traditional counterpart too. However, cost will be a major challenge and sales data indicated that <a href="https://www.freshplaza.com/oceania/article/9535792/consumers-are-not-willing-to-pay-more-for-sustainability/" target="_blank" rel="noreferrer noopener">consumers will not pay any significant premium for slaughter-free or more sustainable products</a>. <h2>Who wants to eat meat grown in a factory?</h2> There are also questions around who the consumers will be for cultured meat. Vegans avoid animal products, vegetarians often reject the taste of meat and this new group of <a href="https://www.sciencedirect.com/science/article/pii/S0924224421003952" target="_blank" rel="noreferrer noopener">flexitarians</a>, while interested in trying new products, are seldom converted to <a href="https://www.foodnavigator.com/Article/2021/11/16/What-do-flexitarian-consumers-want-Plant-based-innovation-opportunities-revealed" target="_blank" rel="noreferrer noopener">regular customers</a>. In the US at least, this is one of the reasons that the many plant-based meat products have only captured <a href="https://gfi.org/marketresearch/#plant-based-meat" target="_blank" rel="noreferrer noopener">1.3 percent of the meat market</a>. It is also likely that plant-based products will be a <a href="https://www.mckinsey.com/industries/agriculture/our-insights/alternative-proteins-the-race-for-market-share-is-on" target="_blank" rel="noreferrer noopener">major competitor</a> to these new cultured meat products. <h2>Who will be next to approve cell-cultured meat?</h2> While the first cultured meat products have been licensed in Singapore and the US, it is expected more will follow from other regions. Even though <a href="https://www.fao.org/food-safety/scientific-advice/crosscutting-and-emerging-issues/cell-based-food/en/" target="_blank" rel="noreferrer noopener">a recent FAO report</a> identified over 50 potential health risks with cultured meat, it concluded that the overall risk was not greater than that seen with conventional meat products. There could be delays in Europe due to the conservative regulatory approach taken in the EU. In Australia, products are <a href="https://www.abc.net.au/news/rural/2023-06-27/cultured-lab-meat-to-sell-in-australia-to-rival-plant-based-meat/102527330" target="_blank" rel="noreferrer noopener">expected to be approved in 2024</a>. For now though? Well, the message to Aussie meat producers is … don’t sell the farm.

Gratitude amplified: Unlocking the key to happiness and deep connections

In today's fast-paced world, filled with negative news, challenging experiences, and personal losses, finding joy and gratitude can often be a difficult task. As we naturally tend to focus on the negative aspects of life, it becomes essential to pause and cultivate gratitude, which can have a profound impact on our lives and the lives of those around us. What is gratitude? Gratitude involves showing appreciation for the things in life that are important to you, and taking a moment to notice and acknowledge these moments have proven benefits of lifting mood and helping you feel more positive throughout the day. Have you ever stopped to notice that there is something to be grateful for every day if we just take stock? It could be a person who kindly let you merge into traffic, a refreshing breeze on a scorching day, a beautiful rainbow after a heavy downpour, or a thoughtful call or text from a friend. Gratitude is strongly and consistently associated with greater happiness. Gratitude helps people feel more positive emotions, relish good experiences, improve their health, deal with adversity, and build strong relationships. We also know that Gratitude begets gratitude, meaning that any kind act is likely to bring kindness back, in spades! Practice Gratitude – Write down 3 things per day <a href="https://theresilienceproject.com.au/">The Resilience Project</a> changed my life by introducing a simple practice: at the end of each day, we take five minutes to write down three things we are grateful for that happened that day. It could be as simple as a walk in the sun, a phone call from a friend, a stroll with your dog, or even a comforting cup of tea. Engaging in this exercise helps you articulate your gratitude and realise the abundance of things to be grateful for in our everyday lives. I personally experienced the transformative power of gratitude during the two years of COVID lockdown in Victoria while working full-time and home schooling my two boys, aged 8 and 10. Our family embraced this practice each night, which not only changed our outlook on life but also sparked positive conversations during dinner. Surprisingly, it was often the simplest things we were all grateful for, like homemade meals or cherished moments of togetherness. I distinctly remember preparing a hot meal and passing it over our neighbour's fence when their family was unwell with COVID. To our surprise, a few weeks later, they reciprocated with a homecooked meal. In those challenging times, a sense of community became such a source of positivity, and we were immensely grateful for the love that went into that dinner. So why not take the time to stop and smell the roses and practice gratitude? Who knows, over time, you may start to notice your stress levels decreasing, your relationships improving, and be blessed with a strengthened sense of community.

Friends are key to keeping fit

Find yourself losing motivation with your workouts? An exercise buddy can be the best way to kick-start your fitness program and put the fun back into workouts. Here’s why you need an exercise buddy. Get motivated A partner can provide the motivation you need to get out and get active. When you’re tempted to stay in bed or flop on the couch, the influence of an exercise buddy will encourage you to change your mind – even if it’s just so you don’t disappoint them. Numerous studies have shown that having a partner increases the likelihood that you will stick to a fitness routine. Monitor your progress Sometimes it can be hard to see how far you’ve come if you’re exercising alone. Often it takes an independent party to see when you’ve gained strength or flexibility, toned up or increased your stamina. A buddy will help you recognise your achievements and celebrate them. Try new things It can be intimidating to go into a new fitness class or activity on your own. You might feel self conscious in front of others or not want to try that new machine without a bit of moral support. An exercise buddy takes the pressure off and brings a social element to the experience, so you can laugh at your mistakes or ask for help without judgment. Be competitive We’re not suggesting that your workouts need to be fights to the death, but having a buddy will inspire you to run that little bit further or push that little bit harder. You can both keep track of your progress against the other and work harder to keep improving. Because no one likes to fall behind. Safety first Exercising à deux is safer for everyone. It can be hard to listen to your own body and you might not be able to tell when something isn’t right. A buddy gives you a spotter when you’re lifting weights, someone to tell you if a pose looks like it’s placing too much strain in one area or just someone to help you home if you twist your ankle on a run. Another set of eyes helps prevent you exercising with bad form and makes sure you’re getting the most out of it. Laugh a little Above all, an exercise buddy makes working out more fun. You can catch up on gossip while walking, laugh at your novice yoga moves or grab a juice after swimming a few laps. And when something is fun you’re more likely to keep doing it. So buddy up!

This eating habit is key to losing weight

New research has found the time of day you eat is key to losing weight. The findings reveal that your best efforts to cut back may prove ineffective if you’re not timing your meals correctly. A study found that mice lost weight when they were given a reduced calorie diet and only ate during the day. Rodents who consumed the same diet but ate at night did not reap the same results. Lead author of the study, Dr Joseph Takahashi, said, “Translated into human behaviour, these studies suggest that dieting will only be effective if calories are consumed during the daytime when we are awake and active.” Dr Takahashi added, “They further suggest that eating at the wrong time at night will not lead to weight loss even when dieting.” Scientists from the University of Texas Southwestern Medical Center also believe the timing of meals is important as it also affects circadian rhythms, the body’s 24-hour clock. They have highlighted how the research may explain how dietary habits impact lifespan. The study observed this by testing the day/night cycles of mice under different feeding schedules. Two groups of mice were fed at the wrong time during their normal cycle. One group was given 30 per cent less calories and the other group had unlimited food, but both groups were more active at night. Various research has associated sleep problems with an increased risk of obesity. “'It has been known for decades that calorie restriction prolongs lifespan in animals, but these types of studies are very difficult to conduct because they required manual feeding of subjects over many years," Dr Takahashi said “This automated system, which can be scaled up for large and very long longevity studies, provides the means to address open questions about what mechanisms extend lifespan in mammals.” Image credit: Shutterstock The research was published in the journal Cell Metabolism.

"Is it even legal?": Outrage over pub's "sneaky" surcharge

A Sydney hotel has come under fire online after one customer exposed the popular venue for an unexpected - and apparently undeclared - “late night surcharge”. And after taking to Reddit, that same customer found a wave of support from users who agreed the additional fee was ridiculous, with some even questioning the legalities of it. And while they hadn’t initially revealed the name of the sneaky establishment, after a number of requests from fellow Redditors for a “name and shame”, they eventually disclosed that it had been Sydney’s iconic Oxford Hotel. They began their tale by sharing that they’d just been out with a friend, and had been buying “jugs of beer as rounds”. The first was “purchased at 9:18pm for $24.36”, and wasn’t an issue for the two friends. However, trouble arose at 10:37pm when the poster’s next round came about, and the total came in at $33.50. “I paid for it not looking at the price but Apple Pay has notifications when you pay for things,” they explained, “and I noticed the price difference in the notifications. “When I asked the same staff member who served me he said there was a ‘late night surcharge after 10pm’.” They went on to note that they’d never even heard of a late night surcharge before, and were dismayed by the “30% increase! Not exactly a small increase.” “There’s no signage to notify anyone of the fee after 10pm. I’ve never even heard of this practice in Australia,” they said, before asking whether anyone else had had a similar experience before, and “is it even legal?” When someone noted that “surcharges and semi-forced gratuities are becoming commonplace now unfortunately”, they suggested checking out menus beforehand to determine whether or not a particular establishment would be issuing additional fees. But as one user pointed out, the hotel in question didn’t list the late night charges anywhere on their website. Someone else said that while “late charge surcharging is nothing new”, what the customer had paid “seems somewhat excessive”. “Every time I go out in Sydney these days the whole experience just leaves a bad feeling because I feel like I've just been had by someone,” another said. “Ahh, the reverse happy hour. A sad hour, if you will,” one offered. “So sick of this. It needs to stop. Australian Culture is being killed before our eyes by these greedy establishments not willing to pay their staff living wages,” someone else lamented. And as one bartender added, “so many bars will bump their booze prices up at 10pm and midnight to ‘help pay for staff loading’, but won't actually pay their staff penalty rates. just a little bit of extra money for the big wigs”.

Hotel guest wakes to find his toes in the manager’s mouth

A Hilton guest in Nashville has experienced the stuff of nightmares during his overnight stay, having woken in the middle of the night to find the hotel’s manager sucking on his toes. The now-former employee allegedly crept into Peter Brennan’s room using a ‘ghost key card’, according to Brennan’s lawyer, and a warrant has been placed for the arrest of the 52-year-old culprit, David Neal. Brennan is also looking to sue the Hilton Hotel where the incident occurred, WSMV have reported. “I woke up at about 5am,” Brennan explained, “and I was being sexually assaulted by a man who had broken into my room.” Metro police reported that Neal was the night manager at the establishment, and attorney Michael Fisher has claimed that Neal had access to hotel keys despite a criminal past. As court documents note, Neal was previously indicted by the Wilson County Grand Jury in 1996 for second-degree murder in relation to his roommate’s death. In 1997, a jury had found him guilty of manslaughter, while Neal claimed self-defence. And as WKRN have reported, for his 2023 toe sucking offence, Neal allegedly told investigators that he had gone into Brennan’s room without permission using a duplicate key because he could smell smoke and had wanted to check in on its occupant. Brennan, upon waking to find Neal there, confronted his assaulter immediately. He also recognised him as someone who had entered his room the previous day, alongside another hotel employee, to check out a TV issue with the room. "[I] instantly jumped up and was screaming,” he told News Channel 5. “Went into sort of fact-finding mode. ‘Who are you? Why are you in my room? What are you doing here?’ "I could see he was wearing a uniform, he had his name tag on. He was talking to me but not giving me any substantive answers." A spokesperson for the hotel directed the station to the hotel’s local manager for comment, though they refused to comment, telling them that “the safety and security of our guests and team members is our highest priority. We are working closely with the Metropolitan Nashville Police Department, and, as part of company policy, we do not comment on ongoing investigations." Which can’t have come as much comfort to Brennan, who was trying to come to terms with what he’d been through, and noted that he was “having problems sleeping frankly, I’m going through some PTSD, talking to a therapist. "I still don’t really feel safe in my own home." Images: Getty

10 shocking examples of bad hotel etiquette

Travel website Expedia has released an exhaustive study on hotel etiquette, asking thousands of travellers around the world to rank the 10 types of hotel behaviour that aggravate them the most. Some of these examples left us scratching our heads! 10. The elevator chatterbox The 10th most annoying hotel-etiquette-gripe for travellers cited by Expedia is hotel guests with a tendency to be a little too chatting on elevators. While you can’t fault anyone for wanting to have a chat, the confined nature of an elevator can make the conversation a little bit awkward. 9. The boozer at the hotel bar Watching this guy drink his way through his per diem is a sight to behold, and not in a good way. You might just want to have a quiet drink at the hotel bar in peace, but because this guy is hell-bent on turning his business trip into the last days of Rome odds are you’re going to be rudely interrupted. 8. The couple canoodling in the hot tub The one thing we can take solace in here is the fact that a lot of the germs won’t be able to withstand the hot tub temperatures. But the thought of jumping into the biological soup formed by a couple canoodling in the hot tub is one that definitely makes our stomachs turn! 7. The loudly amorous couple Coming in at number seven on the list is the couple that are having the romantic escape of a lifetime, which you have unfortunately had to listen to every minute of. It’s in moments like this many travellers have whispered a silent prayer of thanks that earplugs exist. 6. The group partying by the pool There’s nothing like a relaxing dip in the hotel pool, but when this group is hanging out it’s hard to get a foot in the water! The only thing that seems to be greater than their obnoxious behaviour is their omnipresence outside of the pool everywhere – don’t they have rooms to stay in? 5. The bickering couple Hey, will someone let these two know that they’re on holidays? Whether it’s a very uncivil discussion as to whether they should have a spa or massage tomorrow, or a fire-breathing fight concerning whether they should go to a café or have the breakfast buffet, these two need to calm down a bit. 4. The in-room revellers These people seem to be intent on achieving two things in life – partying all night and inhibiting your ability to get some much needed shut eye as they do so. No amount of pleading (or banging on the hotel walls) will seem to get these people to quieten down and show some respect. 3. The excessive complainers Some people are so intent on complaining you’d think that’s half the reason they went away at the first place. When these people aren’t at the hotel bar questioning the amount of bitters in their lemon lime and bitters at, they’re at the concierge desk making all sorts of ridiculous requests. 2. The hallway hellraisers Often mistaken for a stampede of wild horses (at least by the amount of sound they’re making as they move through the hotel, hallway hellraisers get from the lobby to their hotel room with the grace and finesses of an elephant walking around in platform heels two sizes too small. 1. Inattentive parents Children bring joy into this world, but not when they’re wreaking havoc in hotel lobbies. The only thing worse is the inattentive parents who are too engrossed in their own world’s to control their kids, which is why travellers ranked this as the most aggravating example of poor hotel etiquette. The study also revealed some hidden habits of people staying at hotels, mainly: <ul> <li>26 per cent have hoarded toiletries to take home with them;</li> <li>9 per cent have invited multiple people into their room overnight without telling the hotel;</li> <li>8 per cent have secretly taken items from their hotel room;</li> <li>6 per cent sneak down to the pool first thing in the morning to “reserve” a spot by placing towels on chairs;</li> <li>5 per cent have smoked in a non-smoking room;</li> <li>2 per cent have deliberately eavesdropped on guests in a neighbouring room.</li> </ul> Image credits: Getty Images

Federal Budget 2023: How to make the most of the key promises

Treasurer Jim Charles has handed down his first budget for 2023/24, offering a series of measures aimed at tackling the cost-of-living crisis. Millions of Australians will receive a boost from the federal government medical care, bills and welfare payments, amid the forecast that the budget will be be in the black with a surplus of $4bn. Here’s what it means for you: Bill help Those who are on the pension, a seniors card holder or a recipient of family tax benefits A and B will be eligible to get help with energy bills thanks to a deal between the states and Commonwealth that’s worth $1.5bn. That means over five million eligible households and one million eligible small businesses will benefit from the scheme. The relief will come in the form of credits that apply directly to their power bills rather than cash, and the amount they receive will depend on the state they live in. Medicare Relief The incentives paid to GPs who bulk bill 11.6m eligible Australians including children under 16, pensioners and other concession card holders will increase. GPs will be able to claim the incentives for in-person consultations over six minutes long and certain telehealth consultations. GPs who bulk bill patients in the city will be paid a new incentive of $20.65 compared to the previous rate of $6.60, while regional GPs will receive a $31.40 incentive, up from $10.05. Welfare recipients Over 1.1 million vulnerable Australians will benefit from a $40 fortnightly boost from September, if parliament agrees. The increased base rate will apply to people receiving JobSeeker, Youth Allowance, Parenting Payment (partnered), ABSTUDY, Disability Support Pension (Youth) and Special Benefit. Rental assistance For many renters, this budget means that rent is forecasted to increase over the next year as the market tightens. However, for those currently receiving the maximum Commonwealth Rent Assistance allowance their payments will increase by 15 per cent. Here’s what the Federal Budget will look like at a glance: <ul> <li dir="ltr"> Budget deficit of $13.9 billion in 2023/24 </li> <li dir="ltr"> Commonwealth net debt to rise to $574.9 billion (22.3 per cent of GDP) in 2023/24 </li> <li dir="ltr"> Economic growth to fall to 1.5 per cent in 2023/24 </li> <li dir="ltr"> Unemployment rate to rise to 4.25 per cent in 2023/24 </li> <li dir="ltr"> Inflation as measured by CPI to be 3.25 per cent in 2023/24 </li> <li dir="ltr"> Wages to rise by four per cent in 2023/24 </li> </ul> And here are the key measures the federal budget has promised: <ul> <li dir="ltr"> Energy bill relief for five million households and one million businesses </li> <li dir="ltr"> Triple bulk-billing incentives and more funding for urgent care clinics </li> <li dir="ltr"> Base rate of JobSeeker and other payments to be raised for 1.1 million households </li> <li dir="ltr"> Commonwealth Rent Assistant rise for 1.1 million households </li> <li dir="ltr"> Housing boost including tax breaks for build-to-rent investors </li> <li dir="ltr"> $4 billion extra for renewable energy </li> <li dir="ltr"> Tax breaks for small business to write-off assets and reduce energy costs </li> <li dir="ltr"> Targeted help for jobless aged over 55 </li> <li dir="ltr"> Cut to cost of medicines </li> </ul> Image: Getty Images/ Martin Ollman / Stringer

12 things you should always do before you leave your hotel room

Check under the bed and dresser “I always get down on my hands and knees and look under the bed and under the dresser,” says Suzanne Markham-Bagnera, a former general manager at hotels. Young kids especially like to hide things, and then forget about them. “You get the frantic phone call that a child has left their Lovey, their stuffed animal, or their toy and they realised once they get in their car and start driving, but they’re not able to come right back to the hotel,” she adds. Pull the bed linens back Markham-Bagnera typically removes the bedding to both help out the housekeeper and make sure she hasn’t forgotten anything. “That’s my way of securing: I’ve done the clean sweep of the bed. I’m good,” she says. Guest aren’t expected to strip the bed, but should you decide to, make sure to leave the comforter on a chair or in the closet, not on the floor. And don’t ball the bed linens up with the blanket, keep them separate. Leave the used towels in the tub Markham-Bagnera puts all the towels on the bathtub, especially if they’re still wet. That way they’re out of the way and all together in the pile. And the room attendant only has to pick up one pile of dirty linen. “It makes it a lot faster to pick up,” Markham-Bagnera says. Take the food you want to keep If you’ve used the refrigerator, make sure that you take out the items that you want. “The ones that you don’t want, throw away,” she says. Some guests leave alcohol as a tip for the housekeeper, but policies vary from hotel to hotel on whether they can accept it or not. Stack overflow takeaway boxes next to a waste bin Hotel waste bin are pretty small, and the remnants of last night’s dinner may not fit. If you’ve got overflow, pile the boxes next to the waste bin instead of leaving them scattered all around the room. “The messier you leave the room, the harder it is for the room attendant to clean that room,” Markham-Bagnera says. Check between the mattress and box spring When a room doesn’t have a safe, hotel guests will sometimes hide items they don’t want to leave around the room between the mattress and the box spring. Housekeepers have recovered weapons and sex toys there, Markham-Bagnera says. Move the furniture back If hotel guests are travelling with children, they sometimes move one of the beds against the wall so there’s less opportunity for a child to fall out of the bed. That’s fine, but the courtesy is to move the furniture back where you found it before you leave. Take your medications and supplies with you Forgetting your medication can be dangerous for you, but leaving supplies like needles in your room could also be hazardous to your housekeeper. Also, if you gashed yourself shaving and used a towel to stop the blood flow, separate the towel out from the rest. “Hotels will have protocols for how to clean it or for how they have to bag it and have a company come and dispose of it. Because they can’t just put that in the regular trash and be done with it in a hotel,” Markham-Bagnera says. Make sure you have your charger! “If I had a dollar for every charger that I found, I could take my whole family on vacation,” says hotel manager, Adam Sperling. These days, it’s bad news if your phone dies, so take that last look around. “It’s things that get left behind that can often cause you stress at the end of your journey,” he says. Think about a tip Room attendants are typically paid hourly, so their position is different from a bellhop or a server that might make less per hour with the expectation that they will make more in gratuities, Markham-Bagnera says. That said, room attendants work incredibly hard and tipping is appreciated. Things to consider? The quality of the hotel, whether you’re staying one night or multiple nights, and how messy you’re leaving the room. “If you’ve got a lot of people staying in the room and you’ve got a pullout sofa or a cot, and you’ve used a lot more towels, it certainly is nicer to leave a little extra,” Markham-Bagnera says. Call down to the front desk for transportation Mornings can be hectic at hotels, with out-of-town guests rushing to make meetings and flights in cities they don’t know. You can save yourself some of the hassle by doing a little prep before you leave the hotel room. “Call down and say, ‘hey, I’m leaving at 7.30 tomorrow, can my car be waiting for me?’” Sperling suggests. “That helps everybody. Your car’s waiting for you and we’re not scrambling to go get it at 7.25 when you need it at 7.30.” Book your next stay If you really liked your room and are planning to be back in the area, before you leave your hotel is a great time to rebook, Sperling says. He recommends you ask for the front desk manager for face-to-face treatment that can trump the savings online. “You’re likely to get a great rate, and you’re likely to get upgraded,” he says.

“It tastes like rich”: Hotel sells $32 coffee with gold sprinkles

At the Emirates Palace in Abu Dhabi, you can treat yourself to a cappuccino for a whopping $32AUD, although you’re not really paying for the coffee alone. The cappuccino, which is found at the hotel’s Le Cafe by the Fountain comes with 23-karat gold sprinkled on top and it has been named the Emirates Palace Golden Cappuccino. The pricey cap is not the only item on the menu that is embellished with gold, with the hotel advertising a camel milk vanilla or chocolate ice cream with a 23-karat gold leaf for $29. In the mood for a cold drink? The Emirates Palace has got you covered with their Hawaiian Candy Colada, a mocktail topped with 23-karat gold flakes for $26. Tourists have shared videos on social media, with one showing a barista shaking a can of gold flakes over a row of cappuccinos, much like one would with the average cocoa powder topping. Another video posted by a worker shows her adding gold flakes with a spoon. One TikToker who got to try the luxurious coffee wrote, “The gold cappuccino was 8/10 but the vibes were 100/10.” One user wrote, “It tastes like rich.” Another agreed, writing “It tastes expensive.” A Canadian coffee content creator, Brodie Vissers, better known as The Nomad Barista online reviewed the hotel’s cappuccino on YouTube. “Our drinks have arrived, I’m a little bit nervous. It used to be 24-karat, now they’ve reduced it to 23-karat but it is still gold sprinkled on this coffee,” he said. “I don’t even know what to expect from this drink,” he said before trying the luxurious drink. “It’s actually not bad. Of course the foam on the latte is not like a perfect flat white or anything. It’s actually not as sweet as I expected. It’s got a nice balance to it. It’s an interesting drink. “We cannot forget about the dates. Having dates with coffee is a very traditional thing here in the Middle East. “Let’s see how that pairs with the latte. Wow, that is so good. I recommend it if you’re around. It’s a kind of unique opportunity here in (Emirates) Palace. What better place to drink coffee with gold on top.” Image credit: Instagram

Why study is the key to keeping your brain healthy as you age

Two Over60 community members talk about studying later in life, how it keeps their mind healthy and why they keep going back for more. The word study for many people conjures up memories of restless school days, strict teachers and homework you had to force yourself to complete. However, education isn’t just limited to schools – if you think about our everyday lives, we are constantly learning new things. Whether it’s trying out a new recipe, learning about historic events through a film or attempting to remember algebra so we can help our grandkids, it’s clear learning is a lifelong process. Research consistently shows that keeping your mind active has many health benefits. For over-60s, it helps to keep your mind stimulated and mental faculties in top condition as well as improving your overall wellbeing. It is why there are increasingly more seniors who are seeking to study later in life – and they’re finding they not only love it, but that it’s rewarding in so many ways. For Bernard Macdougall, 73, from Maryborough, Queensland, taking courses and learning new things has been crucial in keeping his mind astute. It was after searching online that Bernard stumbled across the free Open2Study courses. “A couple of year ago I was starting to get a bit anxious about whether I had any brain damage. I had a bit of numbness on the right side of my body and I felt I had a slight impediment in my speech,” he reveals, continuing, “but when I found I could get high marks in these courses I thought well I don’t have to worry, my brain is working, there hasn’t been any deterioration.” Bernard found there was a great variety in courses offered and the option of short one-month timeframes could be easily managed. He ended up taking three courses through Open2Study and another online course through Charles Darwin University. It was a similar case for Peter Keyes, 78, from Albion Park Rail, New South Wales, who has completed four courses through Open2Study. Peter has worked in education all his life so when retirement came around he wasn’t about to stop learning. “You can’t sit around in retirement and twiddle your thumbs,” he laughs, adding, “I live in a retirement village and I encourage all of [the residents] to do some study rather than sit around and watch TV all day! It keeps the brain kicking.” As well as keeping him busy, Peter also found the courses were helpful and informative. “During my career in education I ended up being an administrator looking after buildings so I was interested in one of the courses ‘Project Management’. It gave me a further insight into the processes that I used in setting up the buildings of school buildings,” he explains, continuing, “In [my] retirement village, management occasionally ask me to go into planning meetings and talk about what things [to consider] in terms of buildings and older people.” Studying is not only about learning new things but as Bernard found, it can be personally fulfilling too. “Back in the 70s, I did an arts degree with major studies in anthropology. I saw that Open2Study had a course called ‘<a href="https://www.open2study.com/courses/becoming-human-anthropology-090913%20" target="_blank" rel="noopener">Becoming Human</a>’. I thought, ‘Right I will have a go at that’,” explains Bernard. He soon found he was not only learning about new theories but about what it means to become human. “I was very emotionally involved as it was about human evolution,” he says. Both Bernard and Peter found the online courses easy to manage – all that was needed was a computer and an internet connection to access the course that you could do in the convenience and comfort of your own home. Lectures were presented through short videos, which Peter found convenient: “You can stop it at any time, make a note and then catch up,” he explains. And for those who are worried that studying means taking exams or doing assessments again, Peter advises you not to worry. “When people hear that they’ve got exams or test or assessment to do, they get a bit frightened. But you teach them there’s nothing to it, you can always stop and go back and have another read,” says Peter. While there are assessments – mainly multiple choice – throughout most courses, it’s not about being competitive but having a barometer for your individual progress. It is simply there so you know how much knowledge you have learnt during the course. Bernard found that although he felt apprehensive sometimes, there was a greatly fulfilling feeling of not only accomplishing the assessment but gaining some high marks. “I put a lot of work into study and when you have to press the final submit button, sometimes I was extremely apprehensive because I was anxious to get good marks,” Bernard explains, adding, “I think one has to devote time to it but it’s time I’m happy to spend.” Both Peter and Bernard are quick to reveal that they are not going to stop studying anytime soon. Peter has just signed up to Open2Study’s ‘Innovation for Powerful Outcomes’ course while Bernard is still half way through the ‘User Experience for the Web’ course. “The course is self-paced so I can start again and there’s no deadline for me, thank goodness,” Bernard smiles. After each completing a number of courses, they can’t speak highly enough about how beneficial studying has been for them. “It keeps the little grey cells going,” states Peter, because as he know only too well, “the pool of knowledge, skill, understanding and wisdom is enormous” in the over-60 community. “For me it is very, very important to keep learning as you age. Partly so that I know my brain is still good and not fading away,” Bernard chuckles, continuing, “it is also just a matter of curiosity. I’m just interested in learning new topics.” Images: Getty
