How do airplanes fly? An aerospace engineer explains the physics of flight

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/craig-merrett-1509278">Craig Merrett</a>, <a href="https://theconversation.com/institutions/clarkson-university-4276">Clarkson University</a> Airplane flight is one of the most significant technological achievements of the 20th century. The <a href="https://airandspace.si.edu/explore/stories/wright-brothers">invention of the airplane</a> allows people to travel from one side of the planet to the other in less than a day, compared with weeks of travel by boat and train. Understanding precisely why airplanes fly is an ongoing challenge for <a href="https://www.clarkson.edu/people/craig-merrett">aerospace engineers, like me</a>, who study and design airplanes, rockets, satellites, helicopters and space capsules. Our job is to make sure that flying through the air or in space is safe and reliable, by using tools and ideas from science and mathematics, like computer simulations and experiments. Because of that work, flying in an airplane is <a href="https://usafacts.org/articles/is-flying-safer-than-driving/">the safest way to travel</a> – safer than cars, buses, trains or boats. But although aerospace engineers design aircraft that are stunningly sophisticated, you might be surprised to learn there are still some details about the physics of flight that we don’t fully understand. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.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/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=381&fit=crop&dpr=1 600w, https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=381&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=381&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=479&fit=crop&dpr=1 754w, https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=479&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/577439/original/file-20240222-28-v3tjb4.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=479&fit=crop&dpr=3 2262w" alt="A diagram of an airplane that shows the four forces of flight." /></a><figcaption>The forces of weight, thrust, drag and lift act on a plane to keep it aloft and moving. <a class="source" href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/airplane-cruise-balanced-forces/">NASA</a></figcaption></figure> <h2>May the force(s) be with you</h2> There are <a href="https://www.nasa.gov/stem-content/four-forces-of-flight/#:%7E">four forces</a> that aerospace engineers consider when designing an airplane: weight, thrust, drag and lift. Engineers use these forces to help design the shape of the airplane, the size of the wings, and figure out how many passengers the airplane can carry. For example, when an airplane takes off, the thrust must be greater than the drag, and the lift must be greater than the weight. If you watch an airplane take off, you’ll see the wings change shape using flaps from the back of the wings. The flaps help make more lift, but they also make more drag, so a powerful engine is necessary to create more thrust. When the airplane is high enough and is cruising to your destination, lift needs to balance the weight, and the thrust needs to balance the drag. So the pilot pulls the flaps in and can set the engine to produce less power. That said, let’s define what force means. According to <a href="https://ca.pbslearningmedia.org/resource/4079abf0-7a4b-4f49-80ad-c69cd06a80f9/newtons-second-law-of-motion/">Newton’s Second Law</a>, a force is a mass multiplied by an acceleration, or F = ma. A force that everyone encounters every day is <a href="https://spaceplace.nasa.gov/what-is-gravity/en/#:%7E">the force of gravity</a>, which keeps us on the ground. When you get weighed at the doctor’s office, they’re actually measuring the amount of force that your body applies to the scale. When your weight is given in pounds, that is a measure of force. While an airplane is flying, gravity is pulling the airplane down. That force is the weight of the airplane. But its engines push the airplane forward because they create <a href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/what-is-thrust/">a force called thrust</a>. The engines pull in air, which has mass, and quickly push that air out of the back of the engine – so there’s a mass multiplied by an acceleration. According to <a href="https://www.youtube.com/watch?v=a-wh3fJRdjo">Newton’s Third Law</a>, for every action there’s an equal and opposite reaction. When the air rushes out the back of the engines, there is a reaction force that pushes the airplane forward – that’s called thrust. As the airplane flies through the air, the shape of the airplane pushes air out of the way. Again, by Newton’s Third Law, this air pushes back, <a href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/what-is-drag/#:%7E">which leads to drag</a>. You can experience something similar to drag when swimming. Paddle through a pool, and your arms and feet provide thrust. Stop paddling, and you will keep moving forward because you have mass, but you will slow down. The reason that you slow down is that the water is pushing back on you – that’s drag. <h2>Understanding lift</h2> <a href="https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/what-is-lift/">Lift</a> is more complicated than the other forces of weight, thrust and drag. It’s created by the wings of an airplane, and the shape of the wing is critical; that shape is <a href="https://howthingsfly.si.edu/media/airfoil#:%7E">known as an airfoil</a>. Basically it means the top and bottom of the wing are curved, although the shapes of the curves can be different from each other. As air flows around the airfoil, <a href="https://www.youtube.com/watch?v=UO75jDwGCdQ">it creates pressure</a> – a force spread out over a large area. Lower pressure is created on the top of the airfoil compared to the pressure on the bottom. Or to look at it another way, air travels faster over the top of the airfoil than beneath. Understanding why the pressure and speeds are different on the top and the bottom is <a href="https://airandspace.si.edu/multimedia-gallery/lift-and-copjpg">critical to understand lift</a>. By improving our understanding of lift, engineers can design more fuel-efficient airplanes and give passengers more comfortable flights. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.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/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=385&fit=crop&dpr=1 600w, https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=385&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=385&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=484&fit=crop&dpr=1 754w, https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=484&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/579698/original/file-20240304-24-6df49v.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=484&fit=crop&dpr=3 2262w" alt="A diagram that shows how the airfoil of a plane works." /></a><figcaption>Note the airfoil, which is a specific wing shape that helps keep a plane in the air. <a class="source" href="https://www.gettyimages.com/detail/illustration/how-airplanes-fly-royalty-free-illustration/1401215523?phrase=airfoil+diagram&adppopup=true">Dimitrios Karamitros/iStock via Getty Images Plus</a></figcaption></figure> <h2>The conundrum</h2> The reason why air moves at different speeds around an airfoil remains mysterious, and <a href="https://www.scientificamerican.com/video/no-one-can-explain-why-planes-stay-in-the-air/">scientists are still investigating</a> this question. Aerospace engineers have measured these pressures on a wing in both wind tunnel experiments and during flight. We can create models of different wings to predict if they will fly well. We can also change lift by changing a wing’s shape to create airplanes that fly for long distances or fly very fast. Even though we still don’t fully know why lift happens, aerospace engineers work with mathematical equations that recreate the different speeds on the top and bottom of the airfoil. Those equations describe a process <a href="https://howthingsfly.si.edu/media/circulation-theory-lift">known as circulation</a>. Circulation provides aerospace engineers with a way to model what happens around a wing even if we do not completely understand why it happens. In other words, through the use of math and science, we are able to build airplanes that are safe and efficient, even if we don’t completely understand the process behind why it works. Ultimately, if aerospace engineers can figure out why the air flows at different speeds depending on which side of the wing it’s on, we can design airplanes that use less fuel and pollute less.  <a href="https://theconversation.com/profiles/craig-merrett-1509278">Craig Merrett</a>, Professor of Mechanical and Aerospace Engineering, <a href="https://theconversation.com/institutions/clarkson-university-4276">Clarkson University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Tips

The one in-flight activity to avoid to conquer jet lag

While many people love to travel and explore new destinations, there’s no doubt that the worst part of a holiday is often the long-haul flight. With many holidays, especially ones overseas, a drastic change of timezones can mean jet lag is unavoidable, but there are a few things you can do to make life easy when you land. According to one travel expert, how you feel when you disembark often boils down to your in-flight activities. Sarah Built, who has worked up a lifetime of long-haul travel as the Etihad Airways Vice President of Sales for Australasia, told <a href="https://travel.nine.com.au/latest/flight-tips-how-to-avoid-jet-lag/db8fbda1-2318-44c0-b9fe-e14d11dec70c">9Travel</a> that there is one thing she always avoids onboard in order to land at her destination feeling fresh: alcohol. "Whilst the allure of coffee, cocktails and snacks is real (particularly if you're travelling with kids), they can actually contribute to dehydration and worsen jet lag," she says. Instead of that in-flight beer glass of wine, Sarah says to drink water (with lime added for a twist) or herbal tea to boost your hydration and lessen that groggy mid-flight feeling. Drinking water is obviously also the key to staying hydrated, as Sarah says it's important to start drinking extra water the day before your flight, so you're going in prepared. "I carry a reusable water bottle to keep fluids up during the journey (most airports will have water stations for you to refill easily)," she says, which means you won't need to pay for an overpriced bottle at the airport. "Dehydration can cause headaches and fatigue, and you want to be able to hit the ground running on arrival, so always remember to drink plenty of water," she advises. Image credits: Shutterstock

4 things you’re likely doing that are damaging your hearing

Your hearing is a precious gift, so it’s important to take good care of your ears. We’ve got some advice on the things to avoid, and what you can do to protect your hearing. Using cotton tips Though they’re commonly used for the job, cotton tips should never be used to clean out your ears. In fact, no solid object should be put inside your ears. Cotton tips account for around four per cent of all ruptured eardrums. These innocuous-looking objects can also cause bleeding, scratch your ear canal, or trigger an infection. So put them down and step away. Instead, use a commercial ear cleaner, or even just a few drops of mineral oil, baby oil, or glycerine to soften the earwax. Don’t wait and see If your hearing in one or both ears suddenly disappears without cause, you need to go and see your doctor as soon as you can. It could be inflammation, infection, or a decrease in blood supply to the area. If you need treatment, you’ll likely need it immediately to have any hope of restoring your hearing. Using eardrops without advice There are many over-the-counter eardrops available to help with things like swimmer’s ear. But in extreme cases, these products can cause deafness. Before you use anything, including a home remedy, get your doctor to check that you don’t have a ruptured eardrum. Some people may be born that way, or have had surgery as a child, or suffered an injury. If the ingredients in these drops make their way inside your eardrum, it can cause a lot of pain, and permanent deafness. Always protect your ears It’s incredibly important to protect your ears from permanent damage. Tiny hairs inside your ears act as hearing receptors, and these can be broken by extremely loud noises. Once they’re gone, they don’t come back. So things like loud music, fireworks, machinery, and artillery are all risky to be around. The best thing you can do is cover up with earmuffs whenever you’re around these things – especially if it’s on a regular basis. For extra safety, use earplugs as well. Image credits: Shutterstock

Five tips to help you start new hobbies in retirement

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/alison-bishop-1522973">Alison Bishop</a>, <a href="https://theconversation.com/institutions/university-of-east-london-924">University of East London</a> Retirement can be an exciting but also scary prospect for many. How you fill your time is totally up to you, but with so many choices it can be a bit daunting. But it’s important to make sure you keep active, physically and mentally. Hobbies can <a href="https://www.careuk.com/help-advice/why-are-long-lost-hobbies-important-for-older-people">increase wellbeing</a> by boosting brain function, enhancing social skills and improving fine motor skills. <a href="https://www.researchgate.net/publication/366160647_Psychological_benefits_of_hobby_engagement_in_older_age_a_longitudinal_cross-country_analysis_of_93263_older_adults_in_16_countries">A study carried out in 2022</a> found that spending time on hobbies was associated with lower symptoms of depression and a perceived increase in a person’s sense of health, happiness and overall life satisfaction. However, many older people don’t take up hobbies for all sorts of reasons. This might include fears that they are not as good at something in their older age as they were when they were younger. This fear of trying new things can lead to increased feelings of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4338142/">loneliness and isolation</a>. Here are five tips using <a href="https://ppc.sas.upenn.edu/sites/default/files/ppintroarticle.pdf">positive psychology</a> that could help you or someone in your life if they are scared or nervous about picking up a hobby. <h2>1. Broaden your strengths</h2> Our idea of what we are good at is formed at a very young age and often reflects subjects that we were good at in our school days. Positive psychology’s “<a href="https://www.viacharacter.org/character-strengths-and-virtues">theory of strengths</a>” encourages us to think more broadly about what constitutes a strength. For instance, it considers curiosity, kindness and bravery as strengths. When applied to choosing a hobby, it means that if you believe one of your strengths is kindness, you could consider working in outreach or charity as a hobby or spending time speaking with people who are housebound. <h2>2. Find activities you already enjoy</h2> The “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1693418/pdf/15347528.pdf?inf_contact_key=9944754ba1372fa9ce5ee1421d8427bc">broaden and build theory”</a> suggests that when we feel positive emotions such joy or love, we are more likely to engage in new activities, thoughts and behaviours. It follows then, that if you look at times in your life when you experience these emotions this could help you start a new hobby. So, if you enjoy walking in the countryside, then the theory suggests that those feelings would enable you to join a rambling club. <h2>3. Remember moments you’ve lost track of time</h2> Another way to identify an activity that would be good to do is by using “<a href="https://www.medicalnewstoday.com/articles/flow-state#what-it-is">flow theory”</a>. This suggests that when we are doing something that we become completely absorbed in, that our brainwave patterns change and we can lose track of time. For this to happen, we need an activity that is meaningful to us to complete, with just the right amount of challenge so that it is not too easy or too hard. An exercise that reveals your personal flow template involves looking back on your life to find as many times as possible when you’ve been doing something and completely lost track of time. Write these down and see if these moments have anything in common. For example, are they all creative activities or all outdoors and physical? This will reveal something about yourself and the type of activity that is aligned with who you are, and could suggest new hobbies. <h2>4. Be kind to yourself</h2> “<a href="https://self-compassion.org/">Self-compassion theory</a>” teaches us the importance of being as kind to ourselves as we would be to a friend. When we are thinking about what we are good at, we can be unkind to ourselves by comparing ourselves unfavourably to others or to an imagined high standard. Self-compassion theory states that our imperfections make us human, and it is our shared knowledge of this that connects us to others. Where a goal in an activity is kindness with ourselves and those doing the activity with us rather than performance, we can access a new more meaningful reason to take part in something. <h2>5. Imagine your perfect day</h2> The last tip from positive psychology involves creating <a href="https://www.thepositivepsychologypeople.com/reflections-on-a-beautiful-day/">a story of the perfect average day</a> and then planning to actually live it. How do your hobbies fit into this? How does this day tap into your broadened idea of your strengths? How does it include kindness to yourself and others? It also helps to identify goals either for retirement more generally or for participating in a hobby. By picturing the perfect average day you can create more meaning and purpose in life by seeing how all the parts of your life fit together. It also reveals short term goals for example, if you plan to go to an art club but can’t get there, then a goal could be asking for a lift from another club member. When these pieces are in place, hope is ignited, and a vision created of how life can go forward so that you really can live your best retired life. <a href="https://theconversation.com/profiles/alison-bishop-1522973">Alison Bishop</a>, Lecturer in Positive Psychology Coaching, <a href="https://theconversation.com/institutions/university-of-east-london-924">University of East London</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Retirement Life

Here’s what happens to your body during plane turbulence – and how to reduce the discomfort it causes

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> This week has seen another barrage of <a href="https://www.theguardian.com/uk-news/2024/jan/22/uk-weather-storm-jocelyn-to-follow-isha-with-more-strong-winds-and-heavy-rain">unsettled weather</a> sweep across the UK, with many flights delayed or cancelled. Some of those who were fortunate enough to take off found themselves arriving at destinations that weren’t on their boarding passes – such as passengers travelling from Stansted to Newquay who eventually diverted to <a href="https://uk.news.yahoo.com/storm-isha-creates-flight-diversion-142821278.html">Malaga</a>. One thing that was consistently described by passengers was that parts of the flights and the attempted landings were some of the most unnerving they’d ever experienced, due to turbulence. Turbulence results from uneven air movement, which is <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL103814">increasing</a> in frequency. If you turn your hair dryer on at home and hold it still, the air moves at a constant rate, but once you begin drying your hair and moving the hairdryer around, the air movement becomes uneven, that is to say, turbulent. Although turbulence may be unnerving and make you feel unwell, it is important to recognise that it is very common and typically <a href="https://pubmed.ncbi.nlm.nih.gov/18018437/">nothing to worry about</a> if you’re in your seat with your seatbelt fastened. <h2>How the body detects and responds to turbulence</h2> The body recognises itself within any environment. Its relationship with objects in terms of distance and direction is called <a href="https://www.sciencedirect.com/science/article/abs/pii/B9780123750006003414">spatial orientation</a>. When flying, this is typically moving forwards, ascending, some turns and a descent. However, turbulence disrupts this relationship and confuses the sensory information being received by the brain – it makes the body want to respond or recalibrate. Our inner ears play a pivotal role in all this. It consists of complex apparatuses that undertake more than hearing. These include the cochlea, <a href="https://www.ncbi.nlm.nih.gov/books/NBK279394/">three semi-circular canals</a>, <a href="https://radiopaedia.org/articles/utricle-ear?lang=gb">the utricle</a> and <a href="https://radiopaedia.org/articles/saccule-ear-1?lang=gb">the saccule</a>. The cochlea is responsible for hearing. It converts <a href="https://www.ncbi.nlm.nih.gov/books/NBK531483/">sound energy into electrical energy</a> that is then “heard” by the brain. The remaining structures are responsible for the balance and position of the head and body. The semi-circular canals are positioned in a vertical (side to side), horizontal and front-to-back plane, detecting movement in a nodding, shaking and touching ear-to-shoulder direction. Attached to these canals are <a href="https://www.ncbi.nlm.nih.gov/books/NBK532978/">the utricle and saccule</a>, which can detect <a href="https://www.ncbi.nlm.nih.gov/books/NBK10792/">movement</a> and <a href="https://www.cell.com/current-biology/pdf/S0960-9822(05)00837-7.pdf">acceleration</a>. All of these apparatuses use microscopic hair cells in a specialised fluid called <a href="https://www.ncbi.nlm.nih.gov/books/NBK531505/">endolymph</a> that flows with the head to create a sense of movement. When the plane encounters turbulence, this fluid moves around, but unpredictably. It takes <a href="https://www.ncbi.nlm.nih.gov/books/NBK518976/">about ten to 20 seconds</a> for the fluid to recalibrate its position, while the brain struggles to understand what is going on. When the aircraft hits turbulence, the balance apparatus <a href="https://www.frontiersin.org/articles/10.3389/fneur.2023.949227/full">cannot distinguish</a> the movement of the plane from that of the head, so the brain interprets the aircraft movement as that of the head or body. But this doesn’t match the visual information being received, which causes sensory confusion. The reason the inner ear causes so much confusion is because during flights you are devoid of your primary sensory tool relative to the external environment – your sight and the horizon. Eighty per cent of <a href="https://www.ncbi.nlm.nih.gov/books/NBK518976/">spatial information</a> comes from your eyes during flight. However, you only have the seat in front of you or the cabin as a reference point, which means your inner ear becomes the dominant sensory message to the brain during turbulence and disrupts the <a href="https://www.ncbi.nlm.nih.gov/books/NBK545297/">“vestibulo-ocular reflex”</a>. This reflex keeps your vision <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4130651/">aligned</a> with your balance or expected position. Vision is the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6777262/">most valued</a> of the senses and one-third of the brain is attributed to its function, reinforcing its importance in spatial orientation. This sensory mixed messaging often results in things like dizziness and sweating as well as gastrointestinal symptoms, such as <a href="https://www.airmedicaljournal.com/article/S1067-991X(02)70038-2/fulltext">nausea and vomiting</a>. Motion sickness can be triggered by turbulence and although research into specific airsickness is limited, other modes that induce motion sickness suggest that <a href="https://pubmed.ncbi.nlm.nih.gov/16018346/">women</a> are <a href="https://pubmed.ncbi.nlm.nih.gov/26466829/">more susceptible</a> than men, particularly in the <a href="https://pubmed.ncbi.nlm.nih.gov/16235881/">early stages</a> of the menstrual cycle. The turbulence also causes an increase in your heart rate, which is already higher than normal when flying because of a <a href="https://pubmed.ncbi.nlm.nih.gov/15819766/">decrease in oxygen saturation</a>. <h2>What about the pilots?</h2> Commercial pilots accrue thousands of hours at the controls, they are subject to the same forces as the passengers. Over time, they can <a href="https://academic.oup.com/milmed/article/180/11/1135/4160573">adapt to these forces</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/15828634/">experiences</a>, but they also have a couple of additional resources that most passengers don’t. They have the view out of the cockpit windows, so have a horizon to use as a reference point and can see what lies immediately ahead. If it is cloudy or visibility is low, their instruments provide additional visual <a href="https://www.faa.gov/sites/faa.gov/files/regulations_policies/handbooks_manuals/aviation/phak/19_phak_ch17.pdf">reference</a> to the position of the aircraft. This doesn’t mean they are immune to the effects of turbulence, with some studies reporting up to <a href="https://pubmed.ncbi.nlm.nih.gov/26540704/">71% of trainee pilots</a> reporting episodes of airsickness. <h2>How to reduce the discomfort</h2> A window seat can help, or even looking out the window. This gives the brain some sensory information through visual pathways, helping calm the brain in response to the vestibular information it is receiving. If you can get one, a seat towards the front or over the wing reduces the effects of turbulence. Deep or rhythmical breathing can help reduce motion sickness induced by turbulence. Focusing on your breathing <a href="https://pubmed.ncbi.nlm.nih.gov/25945662/">calms the nervous system</a>. Don’t reach for the alcohol. While you may feel it calms your nerves, if you hit turbulence it’s going to interfere with your <a href="https://pubmed.ncbi.nlm.nih.gov/7610847/">visual and auditory processing</a> and increase the likelihood of vomiting. If you suffer from motion sickness and are worried about turbulence while flying, then there are also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6241144/">drugs that can help</a>, including certain <a href="https://www.nhs.uk/medicines/cinnarizine/about-cinnarizine/">antihistamines</a>. Finally, it’s important to remember that although turbulence can be unpleasant, aircraft are designed to withstand the forces it generates and many passengers, even frequent fliers, will rarely encounter the most severe categories of turbulence because pilots actively plan routes to avoid it.<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/221780/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Pilot reveals area with worst turbulence

Pilot and former Bachelor Australia star Jimmy Nicholson has revealed which area in the world has the worst turbulence in a viral video. Nicholson, who has over five years of experience, took to TikTok to explain the areas where pilots can expect the worst turbulence and how he believes that the recent Singapore Airlines <a href="https://www.oversixty.co.nz/travel/travel-trouble/victim-identified-after-plane-hits-deadly-turbulence" target="_blank" rel="noopener">horror flight</a> did not actually experience a "sudden drop". In the clip, he explained that pilots can expect the worst turbulence around the equator in what is called the Intertropical Convergence Zone (ITCZ). “This is where the winds with the northern hemisphere often converge with the winds of the southern hemisphere often causing bad weather and turbulence,” he said. He added that the ITCZ changes throughout the year, with it affecting different areas between January and July. “As you can see here, this is the approximate location of the convergence zone on the 21st of May,” he explained using a graph that showed an area that was “the exact area of where the [Singapore Airlines] incident happened." “As you can see from flightradar, the flight was tracking from Singapore to London and then made a left turn and ended up diverting into Bangkok," he added. <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: 573px; 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%2F7371614320200830226&display_name=tiktok&url=https%3A%2F%2Fwww.tiktok.com%2F%40jimmy_nicholson%2Fvideo%2F7371614320200830226&image=https%3A%2F%2Fp16-sign-sg.tiktokcdn.com%2Fobj%2Ftos-alisg-p-0037%2FowREoIPwwA1lAs31IifkpzBASmJt4iCODZ0sBN%3Fx-expires%3D1716962400%26x-signature%3D%252BkhZRFhuPeWTiEKTMAFYLK0EcTU%253D&key=5b465a7e134d4f09b4e6901220de11f0&type=text%2Fhtml&schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> He said that the 6000 foot drop was not a "sudden" drop as a result of severe turbulence, but a controlled descent. “The plane descended from 37000 feet at six minutes past the hour, down to 31000 feet at 12 minutes past the hour,” he said. “This is not a sudden drop due to turbulence, this is a controlled descent likely because the plane needed to divert into Bangkok, or because they were descending out of the turbulence. “This is a very sad and very rare event,” he continued. “But it is important to remember that these things don’t happen very often." He added that pilots do their best to avoid turbulence, but sometimes it does happen unexpectedly. “This is why pilots always say on the PA when you’re seated make sure you seatbelt is fastened in case we experience an unexpected turbulence.” Image: TikTok

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

Travel Tips

Everything you need to know about tipping in the US

There are few social customs in the US more confusing to travellers than tipping. To most Americans, gratuities are normal, like adding sales tax at the register. To foreign visitors, though, the very idea can induce anxiety or panic. We're notoriously poor tippers. Partly this is accidental ignorance, but partly it is self-righteous rejection of an institution many of us see as unfair. I once had a meal in New York with a woman from Brisbane who refused to tip "on principle." I nodded in agreement ... and then tipped for both of us. The truth is, federal minimum wage for adults in the US is just US$7.25 an hour. In industries where tipping is routine, employers are legally allowed to pay wages as low as US$2.13 an hour. So while travellers may stage a quiet rebellion, refusing to tip, the bereaved party is never going to be the restaurant owners (who earns their profit through the itemised bill), but the poor waiters. Until the US government raises minimum wages to Australian levels (something that will probably never happen), tipping is here to stay. Which means travellers need to accept it, then learn the rules. First rule: After clearing immigration get your hands on a stack of "singles" (US$1 bills). You're going to need them. Getting around In theory, tips should only go to people who are helpful; the more helpful, the more bountiful their reward. In reality, tips are par for the course, and to "stiff" somebody is tantamount to slapping them in the face. If a airport porter helps you with your bags, give them US$1-2 per bag. If they meet you at the gate with a wheelchair, give them US$3-5. For most travellers, the first real test comes with transports away from the airport. If you're lucky enough to have a hotel worker collect you from Arrivals, give them US$10-15 for the effort. If you take a taxi, a little more thought will be required. Many taxis now have seat-back displays that offer "default tipping" amounts at the end of a journey: in New York, 20, 25, and 30 per cent. You should only really tip 30 per cent if the taxi turns out to be the Batmobile, getting you to your destination in record time. Even 20 per cent can sometimes feels a little high. Tipping is subjective: I often manually override the default, leaving 15-20 per cent, or a few extra dollars if I'm paying in cash. If you hire a car and take advantage of valet (all but mandatory in Los Angeles), be prepared to tip the worker US$3-5 upon pick-up, depending on how ritzy the establishment is. A quick rule of thumb: more ritz equals more tip. Hotels If you arrive at the hotel and somebody opens the door for you, that's on the house. If they carry your bags, that is not on the house. Give them US$2-3 a bag. If the hotel has a concierge, their friendliness isn't contingent on your generosity. But if they perform a service for you - book a trip, hire a car, charter a private jet to the Bahamas - acknowledge this effort with US$10-20 at the end of your stay, presented with a handshake. One case where tipping can have a direct impact on the quality of service you receive is housekeeping. Each morning, leave US$2-5 on your pillow with a thank you note. This ensures different cleaners get their due, and it also means cleaners will be extra diligent for the rest of your stay. If you think this is a little rich, keep in mind that these people are picking up your dirty towels, so spare change for a cup of coffee is the least you can do. One point of confusion with hotel tipping is the in-room dining. Some hotels include a default tip on their dining bills; some include a "service charge," which goes to the hotel, and should not be treated as a tip. If there's no obvious tip included on the bill, slip the server 15-20 per cent when they knock on your door. Dining and drinking Nobody can force you to tip in a restaurant, though they can try to counteract your miserliness by stating on the menu that tips are automatically added to the final charge. This is increasingly common in areas catering to large numbers of foreign travellers; it's also pretty standard when your table has more than six people. If tips have been added by the time you come to hand over your card, no further gratuity is needed. If no tip has been included, you might need to leave some money on the table. How much exactly depends on what kind of table it is. If it is a fast food table, no tip. If it is a table at a restaurant ranging from modest diner to upmarket eatery, 15-20 per cent for the waiter is standard (err on the high side in major cities like New York and San Francisco). If you leave less than 15 per cent, staff will assume you weren't happy with their service. If you leave two pennies on top of the bill - a code - they will know you were very unhappy, and feel bad even as they silently loathe you for being a Scrooge. It is almost never okay to withhold a tip; if you're considering doing that, you should also be considering complaining to the manager. If it is a very fancy restaurant, perhaps one with Michelin stars, prepare to hand over 25 per cent of the bill (before tax) to the waiter, who will divide it up among his or her support staff. You should also tip the sommelier if they suggest wine, and perhaps the maitre'd, if they gave you a fabulous table. Always, without exception, tip a bartender a dollar for every drink; bigger tips can mean stronger second cocktails in my experience. As for coffee shops, despite the increasing prevalence of tip jars, and "suggested tips" when paying with a card, this is cheekiness and should only be taken seriously if the barista goes out of their way, like the man who once drew Darth Vader in my cappuccino crema. Everything else This guide covers the most common situations a traveller will have to contend when in the US, though the list is not exhaustive. For example, do you tip a massage therapist? Yes, 10-20 per cent. A hairdresser? Same. Tour guide or hiking leader? 15-20 per cent of the total charge, depending on their performance. That Elvis impersonator who officiated your wedding in a Las Vegas chapel? Same. Tip anyone, in fact, that provides you with a service: 15 per cent is a good default to keep in mind. Just remember, nobody is affronted by the offer of a gratuity, so you shouldn't feel bashful about giving one. Written by Lance Richardson.

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

Catriona Rowntree shares her Europe travel hacks she picked up from locals

After decades of hosting Getaway, Catriona Rowntree has learned a thing or two about travelling. Along the way, the 52-year-old has picked up some must-know secrets from locals that every traveller should know before heading to Europe. While in Mallorca in Spain, Rowntree quizzed locals on how to make the most out of her experience, and what faux pas to avoid. She was given advice on the best way to start a day at the markets, told why you should never rent an Airbnb or buy seafood on a Monday, why takeaway coffee is a bad idea and the secret to a longer, healthy life. The TV host shared a little known secret when it comes to buying fresh fish, and said travellers should not buy fish on Monday, because fishermen don’t fish on Sundays, meaning fish purchases on Mondays won’t be fresh. “The life expectancy of a Spaniard is 84, they're a healthy lot, loving a Mediterranean diet, a dollop of sun and a good climate,” she added. The presenter also discovered that all the locals she has spoken to don't like Airbnb accommodation and prefer for tourists to stay in hotels. “All the locals I've spoken to say that's what's pushing them out of their apartments as the town centres are slowly gentrified,” she said. “The average wage is low, most locals rent, sadly landlords prefer the higher fee of an Airbnb. Not cool!” Catriona's final tip is not to get your coffee takeaway, but rather sit down in a cafe, enjoy your coffee and take it slow. “People sit down to enjoy their coffee, they don't get a takeaway: 'If you can't sit for five minutes and talk to a person what's wrong with you!',” she said. Catriona said she was told by a local that the best way to start your day is to explore the markets by getting a hot chocolate and some churros. “Not every day as you'll be round, but market day for sure," she said.

How to avoid 6 common tourist scams

Often when people are on holidays their focus is on relaxing or seeing the sights of the area. But if you don’t keep your wits about you, it’s possible you might end up losing everything to scammers who will do anything to get their hands on your belongings. Here we have six common scams to look out for while you are travelling abroad. Scam 1: You are in a busy bar in a tourist friendly area when some locals ask where you’re from and offer to buy you a drink. Without thinking, you accept the drink and then find yourself waking up hours later without any of your belongings as you’ve had your drink spiked. Solution: If people seem too friendly, be aware that they may be scammers. Don’t accept drinks from people you don’t know, and don’t leave your drink unattended to use the bathroom. Scam 2: You are about to put your handbag and computer on the conveyer belt to go through the scanner. The people in front of you walk through the metal detector and while one goes through, the other sets off the alarms. They step back into where you are standing and take their time removing wallets and coins from their pockets. While you are waiting for your turn to walk through the metal detector, the other person has taken your belongings and is long gone. Solution: Don’t place your items on the conveyer belt until there is no one else waiting in front of you to go through the metal detector. Scam 3: In a busy area such as after a concert or a busy night like New Year’s Eve it can be impossible to get public transport or a taxi back to your hotel. A friendly looking guy comes by and offers you a lift for a reasonable fee using his private car. The scam itself can then range from being charged an exorbitant amount when you arrive at your hotel – or you could even find yourself robbed and dropped by the side of the road with no way home. Solution: However tempting it is, never get in the car with an unlicensed taxi driver. This is even more important to note if you are travelling alone. Scam 4: While you are waiting with your luggage for a train or bus, a passer-by appears to drop their wallet and walk off without noticing. You might try to do the right thing by grabbing the wallet and running after the person to return it. By the time you get back, your luggage is missing. Solution: When travelling alone, never leave your items unattended even if it means you don’t help someone when you normally would. This is especially true in airports where baggage will quickly be confiscated if left alone. Scam 5: You’re taking in the sights when a couple of men dressed as policemen approach you. They demand to see your wallet and let you know that counterfeit money has been given to tourists in the area. When your wallet is returned it has had much of the contents removed. Solution: Police would never demand to see your wallet. If something doesn’t feel right, suggest that you continue the discussion at the nearest police station as you don’t feel comfortable. Most likely they will not push their luck. Scam 6: You receive a phone call in your hotel room late at night from someone claiming to be from the front desk. They apologise for the late call but request that you just confirm your credit card details as their system is playing up. You read out the numbers and hang up. Before too long your credit card has rung up a huge bill as this was a scammer calling you, not a staff member. Solution: Organise payment in person by letting the caller know that you will come down to the front desk to discuss it. Image credits: Getty Images

Julie Goodwin shares her top tips for perfect potatoes every time

Who doesn't love a good, hearty, delicious serving of fluffy and decadent potatoes? Original MasterChef Australia champion Julie Goodwin has shared her ultimate hacks for cooking the perfect potatoes every time, whether they’re mashed, roasted or baked. According to Julie, there are three key things every home cook needs to keep in mind the next time potatoes are on the menu. Make sure you have the right potatoes Depending on whether you want baked, mashed, roasted, or any other way you want to prepare your potatoes, it all starts in the supermarket. "I find that for things like mashed potatoes and gnocchi and rostis you want a floury potato, so the general rule is dirty potatoes for those things," Julie told <a href="https://kitchen.nine.com.au/latest/julie-goodwin-top-three-tips-to-cook-potatoes-robertson-potato-festival/4d16ba12-bf14-4af2-990e-dcf0e89c30ee">9Honey</a>. "And then for stuff like potato salads, boiled baby potatoes, and potato bake, it's better to have a waxy potato because they hold their substance better. And those are the ones that are sold clean, so things like the Pontiac and Desiree with the pink skin or the washed potatoes with the white skin." "If you want to use them in an Irish stew to break down and thicken the sauce you've got to use a floury potato," she says. "So tend to your dirty ones." She says that if you're buying a clean, waxy potato, you won't have to peel them since the skin is supposed to be edible. However, if you're buying a dirty, floury potato, then you're going to want to peel the dirt off first and then wash off the residue. Get those crispy edges As every home cook knows, the key to the perfect roasted potato is for the inside to be soft and fluffy while the outside stays crispy. It can be a tricky balance to master, but Goodwin says there's a simple way to get it right every time. "I like to par boil them before I roast them. Just so that they go a bit fluffy around the edges," she explains. "What happens is those bits go really crispy and lovely." Let the flavour flow When it comes to seasoning your potatoes, it's hard to know what flavours will suit your dish best. According to Goodwin, more is less when you season potatoes, so it's best to close the spice cabinet. "Salt is absolutely the number one, pepper's beautiful [but] it depends on what the meal is," she says. "So if you're doing a bit of a Portuguese or Spanish inspired meal you might put some paprika on there.” "But I really love rosemary and that's beautiful if you pound that up with your salt and put it on the potatoes that makes it really nice."

Aussie cruising fanatics share their top cruise tips

An Aussie couple who are dedicated to cruising have shared their top tips to keep in mind before setting sail. Marty and Jessica Ansen are about to set off on their 130th cruise and have made headlines around the world for their devotion to spending most of their lives at sea. Together they have sailed roughly 770,000 nautical miles over more than 2,300 days on board, which equates to more than six years spent at sea. The Brisbane grandparents, both 77, have just headed off on their tenth trip around the globe, which is also their 52nd consecutive cruise adventure. During all their time spent at seas, the Ansens have learned a thing or two about life onboard, and have shared their top ten tips to make time on a cruise ship as smooth sailing as possible. Their number one tip for cruise travellers is to take a backup credit or debit card, as Marty told <a href="https://travel.nine.com.au/cruising/cruise-tips-couple-princess-cruises-marty-and-jessica-ansen-australia/c61281dd-c47a-41bf-b166-608b581eccdf" target="_blank" rel="noopener">9Travel</a>, "Replacing a lost or stolen card while overseas is not for the fainthearted." The Ansens recommend making a clear and legible copy of your passport, as consulates find it a lot easier if you can provide a copy ready to go when you disembark. After all their years at sea, Marty and Jessica are pro-packers, and recommend wearing all your heaviest clothing when you check in to better adhere to a strict weight limit. "Jessica and I have one piece of luggage, usually under 20kg," Marty said. "We also each have one bag of hand luggage. Going on board, regardless of weather, I wear my heaviest clothing." When it comes to packing, they also advise leaving your toiletries at home. "Leave consumables like shampoo, conditioner, toothpaste and any creams and potions at home as Princess (cruise line) provides basic toiletries and anything you do need can be bought at the first port," Marty said. Marty and Jessica also recommend packing all your essentials in your hand luggage, as it can often take a while for your checked bags to arrive in your cruise ship cabin. "Place all jewellery, passports, visas, medication money and credit/debit cards in your hand luggage for easy retrieval," Marty said. Marty said one thing every traveller must check before setting sail is what electrical connection is used onboard. "Check what electrical connection is used onboard and have the right adapter ready to charge your devices,' Marty said. Many ships have American and European plug points, while newer ones may have USB connections too. When it comes to bringing medications, the Ansens said you should always bring extras, as well as the required paperwork. "As an extra precaution carry copies of scripts so that if you do run out or lose your medications it will be easier to prove what you need to overseas pharmacies or doctors," Marty said. Lastly, like any overseas adventure, the Ansens said it is important to always have travel insurance, and to make copies of your policy. Image credits: X (Twitter)

For instance, <a href="https://www.22seven.com/">22Seven</a> has gained popularity in South Africa due to its compatibility with several financial institutions, including the country’s big five banks. Similarly, <a href="https://www.the-star.co.ke/business/kenya/2021-01-25-budgeting-using-mint-app/">Mint</a> is a popular budgeting tool that is used in Kenya and Nigeria. If you prefer to put pen to paper, some online templates come with <a href="https://www.wonga.co.za/blog/free-budget-template">free printable budgets</a>. Creating your own <a href="https://create.microsoft.com/en-us/learn/articles/how-to-make-excel-budget">Excel spreadsheet</a> is an equally good approach. What matters most is using a tool that you can commit to. <h2>2. Itemising your income and expenses</h2> A budget essentially shows how much you’re spending in relation to how much you’re earning. So once you have selected your budgeting tool, you need to fill in your income and itemise how much you’re spending on each expense in a month. A budget can be considered a cashflow statement because it allows you to track money coming in (income) and money going out (expenses). If you are living within your means, your budget should indicate a surplus – more cash inflows than cash outflows. So budgeting provides an accurate account of your short-term financial position. <h2>3. A realistic account of expenses</h2> When you look at your financial statements, fill your expenses into your budget honestly and accurately. Don’t cheat! Since everyone’s financial situation is different, your budget will also be unique. Even though there is no one-size-fits-all approach to budgeting, it should still consider all of your expenses (both regular and intermittent). A general rule of thumb is that if it’s deducted from your account then you should treat it as an expense. This includes payments for housing, medical insurance, fuel, dining out, credit card repayments and even bank fees. <h2>4. Save first, spend later</h2> Now you’ve seen how much you’re spending. Either it’s too much – and you can plan where to cut back – or you have savings at the end of the month. When compiling your budget it’s important to demarcate how much will be in the form of savings. What’s more important is getting into the habit of saving before you spend instead of saving after spending. If you spend first then you’ve deprived yourself of the opportunity to save for a rainy day. Furthermore, <a href="https://eprints.hud.ac.uk/id/eprint/10231/1/Microsoft_Word_-_submitted_version_3rd_June_201.pdf">research</a> has shown that getting into the habit of saving has a transgenerational effect: it can be considered a cultural value that is passed on from one generation to another. So think of saving as paying yourself first. Once you have done so, you won’t feel guilty for treating yourself because you’ve already done the financially responsible thing by putting your savings aside. <h2>5. Considering assets and liabilities</h2> Once you’ve become comfortable with consistently budgeting, you can take it up a notch by including your assets (everything you own with an economic value) and liabilities (everything you owe) to determine your overall financial position. You can get a clearer picture of your overall financial wellbeing by compiling a list of all your assets, for example your savings and <a href="https://www.investopedia.com/terms/h/home_equity.asp">home equity</a>, in relation to liabilities (such as bank loans). Knowing your long-term financial position can indicate how financially resilient or vulnerable you are. In the event of a financial emergency, you will know which resources you can draw upon to meet an unexpected expense. By creating a budget (and sticking to it), you can protect yourself and your household from financial shocks. Consider the alternative. Imagine you haven’t budgeted and set savings aside. If a financial emergency were to arise, your next best bet would be to borrow the funds you need. You’d have to come up with a plan to repay what you’d borrowed while also building your savings. <h2>A healthy habit</h2> Getting into the habit of budgeting isn’t easy, especially if you haven’t done it before or you’re intimidated by the process. But, as the expression goes, “a journey of a thousand miles begins with a single step”. Think of budgeting as taking a small but important step towards reclaiming control over your finances and improving your financial well-being.<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/214861/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/bomikazi-zeka-680577">Bomikazi Zeka</a>, Assistant Professor in Finance and Financial Planning, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Not good enough": Karl takes aim at airline cancellation

Karl Stefanovic has ripped into Aussie airline Bonza, who cancelled all their flights at the last minute and left people stranded all across the country. One of the travellers who were left abandoned was Tracy Hilbert, who was due to fly out of Melbourne on Tuesday morning to see her family after her father suddenly died on Monday night. However, instead of being with her mother and brother, she instead spent the day stuck inside the airport after a fellow passenger informed her their flight had been cancelled with no warning. Tracy spoke to Karl Stefanovic and Sarah Abo on Today to share how let down she felt by the airline, as they failed to communicate the cancellation with their customers. “I text my husband. He said, ‘yes, it’s been cancelled’ and sent me all the details,” Ms Hilbert told Today. “Then the crew came in and about a 5.45am they said that it’s been cancelled.” Ms Hilbert fought back tears as she told Karl and Sarah the heartbreaking reason why she was so desperate to make her flight. “I’ve actually had my father pass away last night, so I needed to get up there because my brother text me and said that he’s not in a good way.” Ms Hilbert’s husband quickly booked her a flight with the budget airline last night, not realising that as of this morning, services will be “temporarily suspended”. “I’ve never had this problem with them before,” Ms Hilbert said. “It’s only a two-hour flight but now it’s going to take me all day to get up there.” Thankfully for Ms Hilbert, along with thousands of other stranded passengers, Virgin and Jetstar said those who were affected by the cancellation would be assisted to get to their destination. “We are aware of the temporary suspension of Bonza flights,” Virgin posted on X. “We will immediately support any passengers stranded mid-journey by offering complimentary seats on Virgin Australia-operated flights to the airport nearest to their final planned Bonza destination.” While wondering if she would receive a refund for her cancelled flight, Ms Hilbert said she was frustrated with the lack of communication with Bonza, saying, "You can’t talk to anybody, it’s all through emails.” Ms Hilbert said it’s all been “very hard” as she should have been with her mother, brother and other family now. “Oh, sweetheart. Hey, Tracy, we’ll let you go,” Karl quickly responded as Ms Hilbert continued to break down in tears. “Obviously there’s going to be a lot of people who are inconvenienced. You’re inconvenienced in a whole lot more emotional away. And it’s such a big thing for you to be handling right now. And we’re so sorry for your loss.” Karl hit out at the airline saying the very least they can do is communicate with travellers who have been left in the lurch. “It’s not good enough just to say something is cancelled. They might be going through the most, you know, horrible business morning of their lives, but that shouldn’t stop you from communicating with people." “It’s just a basic human necessity. And especially for people like Tracy.” On Tuesday, Bonza CEO Tim Jordan said services will be “temporarily suspended” while discussions surrounding the “viability of the business” take place.

Travel Trouble

As you travel, pause and take a look at airport chapels

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/wendy-cadge-343734">Wendy Cadge</a>, <a href="https://theconversation.com/institutions/brandeis-university-1308">Brandeis University</a> Flying home? It is very likely there is a chapel or meditation room tucked away somewhere in one of the airports you’ll pass through. <a href="http://www.pewresearch.org/fact-tank/2015/07/06/most-of-the-busiest-u-s-airports-have-dedicated-chapels/">Sixteen of the country’s 20 largest airports</a> have chapels, as do many more around the world. I am a <a href="http://www.wendycadge.com/">sociologist</a> of contemporary American religion and have written <a href="http://www.wendycadge.com/publications/airport-chapels-and-chaplains/">two recent articles</a> about airport chaplains and chapels. My interest in airport chapels started as simple curiosity – why do airports have chapels and who uses them? After visiting a few – including the chapel at Logan, my home airport here in Boston – I have concluded that they reflect broader changing norms around American religion. <h2>How airports came to have chapels</h2> The country’s first airport chapels were intended for staff rather than passengers and were established by Catholic leaders in the 1950s and 1960s to make sure their parishioners could attend mass. The first one in the U.S., Our Lady of the Airways, was built by Boston Archbishop Richard J. Cushing at Logan airport in 1951 and it was explicitly meant for people working at the <a href="https://doi.org/10.1093/socrel/srx025">airport</a>. A neon light pointed to the chapel and souvenir cards handed out at the dedication read, “We fly to thy patronage, O Holy Mother of God; despise not our petitions in our necessities, but deliver us away from all dangers, O glorious and blessed virgin.” Our Lady of the Airways inspired the building of the country’s second airport chapel, Our Lady of the Skies at what was then Idlewild – and is today John F. Kennedy airport in New York City. Protestant chapels came later. The first was in New York – again at JFK. It was designed in the shape of a Latin cross and was joined by a Jewish synagogue in the 1960s. These chapels were located at a distance from the terminals: Passengers wishing to visit them had to go outside. They were <a href="https://books.google.com/books/about/Exploring_Interfaith_Space.html?id=on5YNwAACAA">later razed</a> and rebuilt in different area of JFK. In the 1970s and 1980s, Protestant chapels opened in Atlanta, and in several terminals of the Dallas airport in Texas. <h2>Becoming more inclusive</h2> By the 1990s and 2000s, single faith chapels had become a <a href="http://www.tciarchive.org/4534.article">“dying breed.”</a> Most started to welcome people from all religions. And many were transformed into spaces for reflection, or meditation for weary travelers. The chapel at San Francisco International Airport, for example, known as the <a href="https://www.flysfo.com/content/berman-reflection-room-0">Berman Reflection Room</a> for Jewish philanthropist Henry Berman who was a former president of the San Francisco Airport Commission, looks like a quiet waiting room filled with plants and lines of connected chairs. A small enclosed space without any religious symbols or obvious connections to things religious or spiritual is available for services. The scene at the <a href="http://www.atlchapel.org/">Atlanta</a> airport chapel is similar, with only a few chairs and clear glass entrances, to provide space for quiet reflection. Some airports, such as JFK, continue with their “Our Lady” names, indicating their faith-based origins. Others include religious symbols and objects from a range of religious traditions. The chapel in <a href="https://cltairportchapel.org/">Charlotte</a>, North Carolina, for example, has multiple religious texts alongside prayer rugs, rosary beads and artistically rendered quotes from the world’s major religions. Pamphlets on topics ranging from grief to forgiveness are available for visitors to take with them at the Charlotte airport. <h2>Different airports, different rules</h2> As these examples show, <a href="https://doi.org/10.1093/socrel/srx025">no two airports</a> have negotiated chapel space in the same way. What is permissible in one city is often not in another. Often, it is local, historical and demographic factors, including the religious composition of the region, that influence decisions. These could even be based on who started the chapel, or how much interreligious cooperation there is in a city. Certain airports such as Chicago’s <a href="http://www.airportchapels.org/">O'Hare</a> have strict rules regarding impromptu religious gatherings whether inside the chapel or out. Some use their public address systems to announce religious services. Others prohibit such announcements and do not even allow airport chaplains to put out any signs that could indicate a religious space. If they are included in airport maps, chapels tend to be designated by the symbol of a person bent in prayer. But even then, they can be difficult to spot. About half of the existing chapels are on the pre-security side of the airport and the other half accessible only after passengers pass through security. <a href="https://doi.org/10.1093/socrel/srx025">Only four large American airports</a> – Las Vegas, Los Angeles, Philadelphia and New York’s LaGuardia – do not have chapel spaces, although opening such a space is under consideration. In the interim, at LaGuardia, a Catholic chaplain holds mass in a conference room. <h2>What’s the future?</h2> The reasons for these spaces and their variations are idiosyncratic and intensely local. These chapels reveal a range of approaches to contemporary American religion and spirituality. So on your travels, keep an eye out for these chapels. Note their similarities and differences and recognize how important local histories are to how church-state issues are resolved – at airports and beyond.<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/87578/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/wendy-cadge-343734">Wendy Cadge</a>, Professor of Sociology and Women's, Gender and Sexuality Studies, <a href="https://theconversation.com/institutions/brandeis-university-1308">Brandeis University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Tips

Does hosting the Olympics, the World Cup or other major sports events really pay off?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/ivan-savin-678930">Ivan Savin</a>, <a href="https://theconversation.com/institutions/escp-business-school-813">ESCP Business School</a> After a long battle, <a href="https://www.france24.com/en/europe/20240213-paris-booksellers-stay-olympics-macron-bouquiniste-france">Paris’s beloved bouquinistes will be staying put</a> this summer. The decision, announced on 13 February by the French government, came after considerable public backlash to the police prefecture’s original plan to move part of the iconic Seine booksellers elsewhere for the inauguration of the Olympics Games on 26 July. Meanwhile, less than six months away from the event, Parisians continue to grumble over a <a href="https://www.ouest-france.fr/jeux-olympiques/cest-aberrant-ce-maire-vient-dapprendre-que-sa-ville-accueillera-les-jeux-de-paris-ab1fa968-cfd1-11ee-89c0-6cefac77e04a">lack of consultations</a> with locals, warnings of <a href="https://www.rfi.fr/en/france/20231130-paris-vehicle-traffic-to-be-heavily-restricted-during-2024-olympic-games">gridlocked traffic</a>, closed metro stations, extensive video surveillance and other grievances. So for host countries, what was the point of the Olympics, again? In academia, the debate about the potential positive and negative effects of large-scale sporting events is ongoing. Although these events are often associated with substantial economic losses, the long-term benefits are the main argument in favour of hosting them. These include the development of material and soft infrastructure such as hotels, restaurants or parks. Big games can also help put the host region on the map as an attractive place for sports and cultural events, and inspire a better entrepreneurial climate. <h2>The pros and the cons of big sporting events?</h2> The cost of these benefits, as the Parisians have realised, is steep. Host countries appear to suffer from increased tax burdens, low returns on public investments, high construction costs, and onerous running cost of facilities after the event. Communities can also be blighted by noise, pollution, and damage to the environment, while increased criminal activity and potential conflicts between locals and visitors can take a toll on their quality of life. As a result, in the recent past several major cities, including Rome and Hamburg, <a href="https://www.dw.com/en/6-cities-that-rejected-the-olympics/a-46289852">withdrew their bids to host the games</a>. A common feature of the economics of large-scale sporting events is that our expectations of them are more optimistic than what we make of them once they have taken place. Typically, expenditure tends to tip over the original budget, while the revenue-side indicators (such as the number of visitors) are rarely achieved. When analysing the effect of hosting large-scale sporting events on tourist visits, it is important to take into consideration both the positive and negative components of the overall effect. While positive effects may be associated with visitors, negative effects may arise when “regular” tourists refuse to visit the location due to the event. This might be because of overloaded infrastructure, sharp increases in accommodation costs, and inconveniences associated with overcrowding or raucous or/and violent visitors. On top of that, reports of poverty or crime in the global media can actually undermine the location’s attractiveness. <h2>When big sporting events crowd out regular tourists</h2> In an <a href="https://doi.org/10.1177/1527002523120639">article published in the Journal of Sports Economics</a> with Igor Drapkin and Ilya Zverev, I assess the effects of hosting large-scale sporting events, such as Winter and Summer Olympics plus FIFA World Cups, on international tourist visits. We utilise a comprehensive dataset on flow of tourists covering the world’s largest destination and origin countries between 1995 and 2019. As a first step, we built an econometric model that effectively predicts the flow of tourists between any pair of countries in our data. Subsequently we compared the predicted tourist inflow in a hypothetical scenario where no large-scale sporting event would have taken place with the actual figures. If the actual figures exceed the predicted ones, we consider the event to have a net positive impact. Otherwise, we consider that it had a “crowding out” effect on “regular” tourists. While conducting this analysis, we distinguished between short-term (i.e., focusing just on the year of the event) and mid-term (year of the event plus three subsequent years). Our results show that the effects of large-scale sporting events vary a lot across host countries: The World Cup in Japan and South Korea 2002 and South Africa 2010 were associated with a distinct increase in tourist arrivals, whereas all other World Cups were either neutral or negative. Among the Summer Olympics, China in 2008 is the only case with a significant positive effect on tourist inflows. The effects of the other four events (Australia 2000, Greece 2004, Great Britain 2012, and Brazil 2016) were found to be negative in the short- and medium-term. As for the Winter Olympics, the only positive case is Russia in 2014. The remaining five events had a negative impact except the one-year neutral effect for Japan 1998. Following large-scale sporting events, host countries are therefore typically less visited by tourists. Out of the 18 hosting countries studied, 11 saw tourist numbers decline over four years, and three did not experience a significant change. <h2>The case for cautious optimism</h2> Our research indicates that the positive effect of hosting large-scale sporting events on tourist inflows is, at best, moderate. While many tourists are attracted by FIFA World Cups and Olympic games, the crowding-out effect of “regular” tourists is strong and often underestimated. This implies that tourists visiting for an event like the Olympics typically dissuade those who would have come for other reasons. Thus, efforts to attract new visitors should be accompanied by efforts to retain the already existing ones. Large-scale sporting events should be considered as part of a long-term policy for promoting a territory to tourists rather than a standalone solution. Revealingly, our results indicate that it is easier to get a net increase in tourist inflows in countries that are less frequent destinations for tourists – for example, those in Asia or Africa. By contrast, the United States and Europe, both of which are traditionally popular with tourists, have no single case of a net positive effect. Put differently, the large-scale sporting events in Asia and Africa helped promote their host countries as tourist destinations, making the case for the initial investment. In the US and Europe, however, those in the last few decades brought little return, at least in terms of tourist inflow.<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/222118/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ivan-savin-678930">Ivan Savin</a>, Associate professor of quantitative analytics, research fellow at ICTA-UAB, <a href="https://theconversation.com/institutions/escp-business-school-813">ESCP Business School</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

5 tips to keep your dog happy when indoors

The cooler months are well and truly here and the dreary weather is enough to make anyone a little sad, including our furry friends. According to a study by veterinary charity People’s Dispensary for Sick Animals, one in three dogs experience a downturn in mood during winter months. If the rain is preventing you getting out and about, here are five tips to keep your pooch happy and healthy when indoors. 1. Stair work/treadmill/indoor pool Use what you have in your home. If you live in a multi-storey place, playing fetch up or down the stairs is a fun way for your pooch to get a workout. Alternatively, if you have a treadmill at home, use it to walk your dog on a rainy day. Swimming is also a great physical activity, particularly if dogs have joint problems. 2. Obedience training Dust off the training books and work with your pooch to improve their obedience skills. It will keep your furry friend mentally active and dispel any boredom. 3. Hide and seek Dogs need their senses stimulated – it’s why when they’re outside they will listen, sniff and dig out anything that’s out of the ordinary. Keep your furry friend entertained with a game of hide and seek. Place healthy treats around the house to get your pooch curious and exploring old surrounds. 4. Rotation diet Rotating proteins (meats, fish, and poultry) and mixing in different forms of food (wet, dry and raw) will keep your dog interested in food and eating. Consult your vet about the type of diet your dog should be on for optimal health. 5. Play time Interactive toys are a great way to pass time, stimulate and entertain your pooch inside. Puzzle toys, Kong balls with treats stuffed inside or just some one-on-one indoor play time will keep your four-legged friend happy. Image credits: Getty Images

The unique travel hack that is guaranteed to help beat jet lag

Experts have revealed how to beat jet lag on your next overseas holiday, and it all comes down to your modes of transport. Sleep researchers said it's good news for cruise lovers, as exposure to sea air and bright natural light improves sleep to cure the annoying condition quickly. Some experts say to avoid travelling by plane all together, and always opt for cruising holidays instead. However, if you have to travel to your cruise by plane, being on board is a great way to tackle the dreadful feeling, compared with holidaying on land, Panache Cruises said. Dr Lindsay Browning, expert at Trouble Sleeping said exposing yourself to bright lights at the right time after a long-haul flight is one of the most powerful things we can do to boost and help shift circadian rhythm, and being on a ship is the perfect place for that. "As a general rule, you want to get lots of bright light exposure during the daytime and avoid light at night," Browning said. "When travelling on a cruise ship, you will naturally get a lot of bright light exposure during the day, helping your circadian rhythm.” "Further, when travelling by ship you will have a cabin with a proper bed and curtain, enabling you to sleep at night when you want to." The company claimed research showed how prolonged exposure to sea air can improve blood oxygen levels, boost vitamin D, and improve breathing leading to higher-quality sleep, helping to rid travellers of pesky jet lag so they can enjoy their holidays.
