Traveller divides opinion on how early you should arrive at the airport

<p dir="ltr">A plane passenger has shocked even the most organised travellers after admitting that he gets to the airport six hours before his flight departs. </p> <p dir="ltr">Self-described anxious traveller Tim Murray slammed those who have a laxed attitude to an airport arrival time, boldly stating it's their own fault if they miss their flight.</p> <p dir="ltr">“It's not my fault you're late to your flight, so if you're behind me in the security line being like: ‘I gotta get past you I'm late’ you need to manage your time better”' he declared in a short clip posted to TikTok.</p> <p dir="ltr">“I get to the airport six-and-a-half hours before my flight,” he stated, admitting his “extreme anxiety” does play a role in getting there early. </p> <p dir="ltr">“And I wanna sit here and vibe at the airport Chili's with a waitress named Debra who has the most amazing smoker's voice you've ever heard and stories that will last six-and-a-half hours,” he joked.</p> <p dir="ltr">In a comment, Tim admitted that he may have over-exaggerated the six hours, but still saying he gets to the airport several hours early. </p> <p dir="ltr">While Tim seemed smug in bragging about his early arrival, many users pointed out that there are external factors that play into people's travel plans.</p> <p dir="ltr">“People need to remember it's not always the person's fault. If my plane is late that could cause me to miss my connection, no matter how early I was. This has happened to me a few times,” one person pointed out.</p> <p dir="ltr">“Have mercy on us international flyers who need to do immigration baggage claim and run to connecting flight after our first flight was delayed,” another complained.</p> <p dir="ltr">“Dude some people are connections because their flight was late, or stuck in a long customs lines… so many other reasons than being just late,” they pointed out. </p> <p dir="ltr"><em>Image credits: TikTok / Shutterstock </em></p>

10 things you should never do on a cruise balcony

<p>While many cruise ship passengers may think they can abide by their own rules in the comfort of their cabins, there are still many cruise ship etiquette rules to follow.</p> <p>Even though some passengers may have private balconies in their rooms, that doesn't mean you can act as if no one is watching. It's important to follow these rules while in your rooms and on your balcony to ensure you'll never be forced to cop the consequences of bad behaviour. </p> <p><strong>1. Smoke</strong></p> <p>Smoking on cruise balconies is a real no-no. Not only is the wafting smoke an unpleasant smell, but a half-burning cigarette blown back aboard can potentially be a fire hazard.</p> <p><strong>2. Make too much noise</strong></p> <p>One think that’s often forgotten is the fact that when we’re standing on our cruise ship balconies we’re well within earshot of our neighbours, so keep the volume down.</p> <p><strong>3. Go nude</strong></p> <p>The thing people sun bathing in one their cruise ship balcony in their birthday suit don’t realise is many balconies are tiered, so you may actually be in view of others.</p> <p><strong>4. Stand or climb on railings</strong></p> <p>Now this should be obvious, but you should never stand on the railings or the verandah furniture can significantly increase your risk of being thrown overboard.</p> <p><strong>5. Throw items overboard</strong></p> <p>It might be tempting to toss a message in a beer bottle overseas, but there are strict regulations. Not only is this dangerous, it’s also not environmentally friendly.</p> <p><strong>6. Dry clothes  </strong></p> <p>It can be quite difficult to dry your swimmers when you’re off a cruise, but one strong gust of wind could mean you could go the rest of your cruise without bathers.</p> <p><strong>7. Leave the balcony door open</strong></p> <p>On a hot and humid day, leaving the balcony door ajar might seem like a good idea, but the gusty sea breeze can wreak havoc with any loose items in your cabin.</p> <p><strong>8. Light a candle</strong></p> <p>It might seem like it’s a good way to enhance the mood, but any open flame on a cruise ship is a fire hazard, and lighting a candle is almost always against regulations.</p> <p><strong>9. Leave the balcony light on</strong></p> <p>If your cruise balcony has outdoor lighting, make sure you turn if off when you’re not actually using it, to save electricity and not disturb your neighbours.</p> <p><strong>10. Amorous behaviour</strong></p> <p>Cruises are inherently romantic holidays, but you might need to avoid overt displays of affection. As mentioned above, balconies are not be as private as you think.</p> <p><em>Image credits: Shutterstock</em></p>

I’m iron deficient. Which supplements will work best for me and how should I take them?

<p><em><a href="https://theconversation.com/profiles/alannah-mckay-1548258">Alannah McKay</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p>Iron deficiency is common and can be debilitating. It mainly affects women. One in three premenopausal women <a href="https://static1.squarespace.com/static/57bfc0498419c24a01318ae2/t/607fc2e06ace2f22d5ca9a43/1618985699483/20210421+-+IDC+-+economic+impact+of+iron+deficiency+-+FINAL.pdf">are low in iron</a> compared to just 5% of Australian men. Iron deficiency particularly affects teenage girls, women who do a lot of exercise and those who are pregnant.</p> <p>The <a href="https://pubmed.ncbi.nlm.nih.gov/11160590/">body needs iron</a> to make new red blood cells, and to support energy production, the immune system and cognitive function. If you’re low, you may experience a range of symptoms including fatigue, weakness, shortness of breath, headache, irregular heartbeat and reduced concentration.</p> <p>If a blood test shows you’re iron deficient, your doctor may recommend you start taking an oral iron supplement. But should you take a tablet or a liquid? With food or not? And when is the best time of day?</p> <p>Here are some tips to help you work out how, when and what iron supplement to take.</p> <h2>How do I pick the right iron supplement?</h2> <p>The iron in your body is called “elemental iron”. Choosing the right oral supplement and dose will depend on how much elemental iron it has – your doctor will advise exactly how much you need.</p> <p>The sweet spot is between <a href="https://www.sciencedirect.com/science/article/pii/S0098299720300364?via%3Dihub">60-120 mg of elemental iron</a>. Any less and the supplement won’t be effective in topping up your iron levels. Any higher and you risk gastrointestinal symptoms such as diarrhoea, cramping and stomach pain.</p> <p>In Australia, iron salts are the most common oral supplements because they are cheap, effective and come in different delivery methods (tablets, capsules, liquid formulas). <a href="https://www.ncbi.nlm.nih.gov/books/NBK557376/">The iron salts</a> you are most likely to find in your local chemist are ferrous sulfate (~20% elemental iron), ferrous gluconate (~12%) and ferrous fumarate (~33%).</p> <p>These formulations <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3867244/">all work similarly</a>, so your choice should come down to dose and cost.</p> <p>Many multivitamins may look like an iron supplement, but it’s important to note they usually have too little iron – usually less than 20 mg – to correct an iron deficiency.</p> <h2>Should I take tablets or liquid formulas?</h2> <p>Iron contained within a tablet is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3867244/">just as well absorbed</a> as iron found in a liquid supplement. Choosing the right one usually comes down to personal preference.</p> <p>The main difference is that liquid formulas tend to contain less iron than tablets. That means you might need to take more of the product to get the right dose, so using a liquid supplement could work out to be more expensive in the long term.</p> <h2>What should I eat with my iron supplement?</h2> <p>Research <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajh.26987">has shown</a> you will absorb more of the iron in your supplement if you take it on an empty stomach. But this can cause more gastrointestinal issues, so might not be practical for everyone.</p> <p>If you do take your supplement with meals, it’s important to think about what types of food will boost – rather than limit – iron absorption. For example, taking the supplement alongside vitamin C improves your body’s ability to absorb it.</p> <p>Some supplements already contain vitamin C. Otherwise you could take the supplement along with a glass of orange juice, or other <a href="https://ods.od.nih.gov/factsheets/VitaminC-HealthProfessional/">vitamin C-rich foods</a>.</p> <p>On the other hand, tea, coffee and calcium all <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajh.26987">decrease the body’s ability to absorb iron</a>. So you should try to limit these close to the time you take your supplement.</p> <h2>Should I take my supplement in the morning or evening?</h2> <p>The best time of day to take your supplement is in the morning. The body can <a href="https://journals.lww.com/acsm-msse/fulltext/2019/10000/the_impact_of_morning_versus_afternoon_exercise_on.20.aspx">absorb significantly more</a> iron earlier in the day, when concentrations of hepcidin (the main hormone that regulates iron) are at their lowest.</p> <p>Exercise also affects the hormone that regulates iron. That means taking your iron supplement after exercising can <a href="https://journals.humankinetics.com/view/journals/ijsnem/32/5/article-p359.xml">limit your ability to absorb it</a>. Taking your supplement in the hours following exercise will mean significantly poorer absorption, especially if you take it between two and five hours after you stop.</p> <p><a href="https://journals.lww.com/acsm-msse/fulltext/2024/01000/iron_absorption_in_highly_trained_male_runners_.14.aspx">Our research</a> has shown if you exercise every day, the best time to take your supplement is in the morning before training, or immediately after (within 30 minutes).</p> <h2>My supplements are upsetting my stomach. What should I do?</h2> <p>If you experience gastrointestinal side effects such as diarrhoea or cramps when you take iron supplements, you may want to consider taking your supplement every second day, rather than daily.</p> <p>Taking a supplement every day is still the fastest way to restore your iron levels. But a recent study <a href="https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(23)00463-7/fulltext#%20">has shown</a> taking the same total dose can be just as effective when it’s taken on alternate days. For example, taking a supplement every day for three months works as well as every second day for six months. This results in fewer side effects.</p> <p>Oral iron supplements can be a cheap and easy way to correct an iron deficiency. But ensuring you are taking the right product, under the right conditions, is crucial for their success.</p> <p>It’s also important to check your iron levels prior to commencing iron supplementation and do so only under medical advice. In large amounts, <a href="https://www.ncbi.nlm.nih.gov/books/NBK430862/">iron can be toxic</a>, so you don’t want to be consuming additional iron if your body doesn’t need it.</p> <p>If you think you may be low on iron, talk to your GP to find out your best options.<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/235315/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/alannah-mckay-1548258">Alannah McKay</a>, Postdoctoral Research Fellow, Sports Nutrition, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

I’ve recovered from a cold but I still have a hoarse voice. What should I do?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/yeptain-leung-1563747">Yeptain Leung</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>Cold, flu, COVID and <a href="https://theconversation.com/rsv-is-everywhere-right-now-what-parents-need-to-know-about-respiratory-syncytial-virus-208855">RSV</a> have been <a href="https://www.abc.net.au/news/2024-06-21/flu-whooping-cough-rsv-cases-up-as-covid-cases-unkown/104002964">circulating across Australia this winter</a>. Many of us have caught and recovered from <a href="https://theconversation.com/i-feel-sick-how-do-i-know-if-i-have-the-flu-covid-rsv-or-something-else-234266">one of these</a> common upper respiratory tract infections.</p> <p>But for some people their impact is ongoing. Even if your throat isn’t <a href="https://theconversation.com/sore-throats-suck-do-throat-lozenges-help-at-all-184454">sore</a> anymore, your voice may still be hoarse or croaky.</p> <p>So what happens to the voice when we get a virus? And what happens after?</p> <p>Here’s what you should know if your voice is still hoarse for days – or even weeks – after your other symptoms have resolved.</p> <h2>Why does my voice get croaky during a cold?</h2> <p>A healthy voice is normally clear and strong. It’s powered by the lungs, which push air past the vocal cords to make them vibrate. These vibrations are amplified in the throat and mouth, creating the voice we hear.</p> <p>The vocal cords are two elastic muscles situated in your throat, around the level of your laryngeal prominence, or Adam’s apple. (Although everyone has one, it tends to be more pronounced in males.) The vocal cords are small and delicate – around the size of your fingernail. Any small change in their structure will affect how the voice sounds.</p> <p>When the vocal cords become inflamed – known as laryngitis – your voice will sound different. Laryngitis is a common part of upper respiratory tract infections, but can also be caused through misuse.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=366&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=366&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=366&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=460&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=460&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=460&amp;fit=crop&amp;dpr=3 2262w" alt="Two drawn circles comparing normal vocal cords with inflamed, red vocal cords." /><figcaption><span class="caption">Viruses such as the common cold can inflame the vocal cords.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/dry-sore-loss-cough-virus-viral-1821458117">Pepermpron/Shutterstock</a></span></figcaption></figure> <p>Catching a virus triggers the body’s defence mechanisms. White blood cells are recruited to kill the virus and heal the tissues in the vocal cords. They become inflamed, but also stiffer. It’s harder for them to vibrate, so the voice comes out hoarse and croaky.</p> <p>In some instances, you may find it hard to speak in a loud voice or have a reduced pitch range, meaning you can’t go as high or loud as normal. You may even “lose” your voice altogether.</p> <p>Coughing can also make things worse. It is the body’s way of trying to clear the airways of irritation, including your own mucus dripping onto your throat (<a href="https://www.health.harvard.edu/staying-healthy/treatments-for-post-nasal-drip">post-nasal drip</a>). But coughing slams the vocal cords together with force.</p> <p>Chronic coughing can lead to persistent inflammation and even thicken the vocal cords. This thickening is the body trying to protect itself, similar to developing a callus when a pair of new shoes rubs.</p> <p>Thickening on your vocal cords can lead to physical changes in the vocal cords – such as developing a growth or “nodule” – and further deterioration of your voice quality.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=376&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=376&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=376&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=473&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=473&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=473&amp;fit=crop&amp;dpr=3 2262w" alt="Diagram compares healthy vocal cords with cords that have nodules, two small bumps." /><figcaption><span class="caption">Coughing and exertion can cause inflamed vocal cords to thicken and develop nodules.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/dry-sore-loss-cough-virus-viral-1821458126">Pepermpron/Shutterstock</a></span></figcaption></figure> <h2>How can you care for your voice during infection?</h2> <p>People who use their voices a lot professionally – such as teachers, call centre workers and singers – are often desperate to resume their vocal activities. They are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7478078/">more at risk</a> of forcing their voice before it’s ready.</p> <p>The good news is most viral infections resolve themselves. Your voice is usually restored within five to ten days of recovering from a cold.</p> <p>Occasionally, your pharmacist or doctor may prescribe cough suppressants to limit additional damage to the vocal cords (among other reasons) or mucolytics, which break down mucus. But the most effective treatments for viral upper respiratory tract infections are hydration and rest.</p> <p>Drink plenty of water, avoid alcohol and exposure to cigarette smoke. <a href="https://www.healthdirect.gov.au/laryngitis#:%7E:text=You%20can%20help%20your%20voice%20recover%20by%3A%201,avoid%20nasal%20decongestants%20%28these%20make%20your%20throat%20drier%29">Inhaling steam</a> by making yourself a cup of hot water will also help clear blocked noses and hydrate your vocal cords.</p> <p>Rest your voice by talking as little as possible. If you do need to talk, don’t whisper – this <a href="https://www.sciencedirect.com/science/article/abs/pii/S0892199704001730">strains the muscles</a>.</p> <p>Instead, consider using “<a href="https://www.instagram.com/reel/C0d-oNIMM1y/">confidential voice</a>”. This is a soft voice – not a whisper – that gently vibrates your vocal cords but puts less strain on your voice than normal speech. Think of the voice you use when communicating with someone close by.</p> <p>During the first five to ten days of your infection, it is important not to push through. Exerting the voice by talking a lot or loudly will only exacerbate the situation. Once you’ve recovered from your cold, you can speak as you would normally.</p> <h2>What should you do if your voice is still hoarse after recovery?</h2> <p>If your voice hasn’t returned to normal after <a href="https://www.healthdirect.gov.au/laryngitis">two to three weeks</a>, you should seek medical attention from your doctor, who may refer you to an ear nose and throat specialist.</p> <p>If you’ve developed a nodule, the specialist would likely refer you to a speech pathologist who will show you how to take care of your voice. Many nodules can be <a href="https://britishvoiceassociation.org.uk/voicecare_vocal-nodules.htm">treated</a> with voice therapy and don’t require surgery.</p> <p>You may have also developed a habit of straining your vocal cords, if you forced yourself to speak or sing while they were inflamed. This can be a reason why some people continue to have a hoarse voice even when they’ve recovered from the cold.</p> <p>In those cases, a speech pathologist may play a valuable role. They may teach you to exercises that make voicing more efficient. For example, <a href="https://www.youtube.com/watch?v=fwNPp-RS4IY">lip trills</a> (blowing raspberries) are a fun and easy way you can learn to relax the voice. This can help break the habit of straining your voice you may have developed during infection.<!-- Below is The Conversation's page counter tag.

Cruise worker shares what you should always take into a lifeboat

<p dir="ltr">A cruise ship worker has shared the six essentials you should always take if you ever need to get into the lifeboat on a cruise. </p> <p dir="ltr">Lucy Southerton, who has worked on cruise ships for nine years, regularly shares cruising advice on social media to help travellers get the most out of their voyage. </p> <p dir="ltr">In her most recent video, Lucy shared invaluable advice on what items you should take on a lifeboat in the event of an emergency. </p> <p dir="ltr">While many people would instinctively leave all their belongings behind in an emergency, Lucy said there are six things you should always take. </p> <p dir="ltr">The first thing to bring in the event of an emergency is your documentation, such as a form of ID, such as a passport, driving licence or even a visa.</p> <p dir="ltr">The second thing may surprise some people, as Southerton recommends always having lip balm in case of emergencies. </p> <p dir="ltr">The cruise worker said, “[In a life-threatening situation] the body prioritises the distribution of water to essential organs such as the liver and the brain.” </p> <p dir="ltr">“Because of this, the lips receive no water so they are going to dehydrate faster, meaning they could crack. If you are in a lifeboat for a long period of time, your lips are going to be one of the first things that suffer so you should protect them at all costs.”</p> <p dir="ltr">Thirdly, Lucy recommends you should always have sunscreen, as you never know how long you will be exposed to the elements for. </p> <p dir="ltr">She said, “If you are sitting directly under the hatch or where they take the roof off to let the breeze in, you're going to want a hat or sun cream to protect yourself from the beating sun.”</p> <p dir="ltr">“This is not as much of a priority as lip balm, but if you can get hold of some sun cream before entering a lifeboat then you should.”</p> <p dir="ltr">Next up, the veteran cruise-ship worker said you should always take layers of clothes that you can easily take on and off in changing weather.</p> <p dir="ltr">Lucy's penultimate item that passengers should always take on a lifeboat might seem obvious but she warned that it is essential for those who take medication on a regular basis to bring it with them. </p> <p dir="ltr">However, she added, “What they don't tell you to take is stuff like paracetamol, ibuprofen, aspirin, Sudocrem and ointments.” </p> <p dir="ltr">“'While you may not need these types of medication, somebody else on your lifeboat might - it's better to have it and not need it than the reverse scenario. Just shove them in your pocket just in case.”</p> <p dir="ltr">Last but not least, Lucy said you should - as obvious and essential as it may seem - never forget to take water on board a lifeboat. </p> <p dir="ltr">She stressed that “there is only so much water you can fit in a lifeboat, so the water is going to be rationed out”. </p> <p dir="ltr">Lucy continued, “If you can take extra water on board with you, do it, even if it's just in the form of an extra water bottle. [Humans] cannot last long without water so make sure you grab some if you are able to.”</p> <p dir="ltr">Finishing up the video, Lucy reassured passengers that “getting into a lifeboat is the absolute last resort”, adding that it is more likely that anyone on board the ship is taken to an assembly station while emergency services on board attempt to fix any issues that could arise. </p> <p dir="ltr"><em>Image credits: Instagram / Shutterstock </em></p>

"We should give back": Bill Gates' ex-wife on giving away her $16bn fortune

<p>Melinda French Gates has opened up on her decision to give away her fortune after leaving the Bill &amp; Melinda Gates Foundation in June. </p> <p>Melinda, who is reportedly worth $16.8 billion, said that she will stick with her decision to give away her fortune on <em>The Late Show with Stephen Colbert, </em> as it's "the right thing to do for society". </p> <p>"If we grew up in the United States, anybody who has grown up in this country has been really lucky and I don't care who you are," she explained.</p> <p>"To be able to go to a decent school, grow up and pursue your career, and if so you are a billionaire, my gosh, you have benefited from this country, right?</p> <p>"So we should give back."</p> <p>She also feels there is "a responsibility and to do it in a way that's incredibly thoughtful".</p> <p>Melinda, who divorced the Microsoft founder Bill Gates back in 2021, has announced her plans to focus on her organisation Pivotal Ventures, which she founded in 2015.</p> <p>The organisation's aim is to "advance social progress by removing barriers that hold people back."</p> <p>She said that she is  determined to ensure that "women's rights are not only on the agenda, but that women are setting the agenda" – especially after watching women's rights be rolled back internationally over the last few years."</p> <p>"What I saw, part of why our women's rights got rolled back in the United States is that those organisations were starved for funding, and they were playing defense," she explained. </p> <p>Melinda has pledged to donate $1 billion to this end over the next two years. </p> <p><em>Image: Julien De Rosa/EPA/ Shutterstock Editorial</em></p>

So when should you book that flight? The truth on airline prices

<p><em><a href="https://theconversation.com/profiles/yuriy-gorodnichenko-144556">Yuriy Gorodnichenko</a>, <a href="https://theconversation.com/institutions/university-of-california-berkeley-754">University of California, Berkeley</a> and <a href="https://theconversation.com/profiles/volodymyr-bilotkach-145437">Volodymyr Bilotkach</a>, <a href="https://theconversation.com/institutions/newcastle-university-906"><em>Newcastle University</em></a></em></p> <p>How airlines price tickets is a source of many <a href="http://airtravel.about.com/od/travelindustrynews/a/mythticket.htm">myths</a> and urban legends. These include tips about the best day of the week to buy a ticket, last-minute discounts offered by the airlines, and the conspiracy theories suggesting that the carriers use cookies to increase prices for their passengers. None of these three statements is entirely true.</p> <p>Studies have suggested that prices can be higher or lower on a given day of the week – yet, there is no clear consensus on which day that is. Offered prices can in fact drop at any time before the flight, yet they are much more likely to increase than decrease over the last several weeks before the flight’s departure. Further, the airlines prefer to wait for the last-minute business traveler who’s likely to pay full fare rather than sell the seat prematurely to a price conscious traveler. And no, the airlines do not use cookies to manipulate fare quotes – adjusting their inventory for specific customers appears to be beyond their technical capabilities.</p> <p>What is true about pricing in the airline industry is that carriers use complex and sophisticated pricing systems. The airline’s per passenger cost is the lowest when the flight is full, so carriers have incentive to sell as many seats as possible. This is a race against time for an airline and, of course, no company wants to discount its product more than it has to. Hence, the airlines face two somewhat contradictory goals: to maximize revenue by flying full planes and to sell as many full-fare seats as possible. This a process known in the industry as yield or revenue management.</p> <h2>Airlines and their bucket lists</h2> <p>Here is how <a href="http://commons.erau.edu/cgi/viewcontent.cgi?article=1522&amp;context=jaaer">yield management</a> works. For each flight or route (if we are talking about multi-segment itineraries), the airline has a set of available price levels – from the most expensive fully refundable fare to the cheapest deeply discounted non-refundable price. The industry jargon for these prices is “buckets.” Then, seats can be interpreted as balls that are allocated among these buckets.</p> <p>Initial allocation of seats between the price buckets is determined by historical data indicating how well a certain flight sells. For example, fewer deeply discounted seats will be offered on a flight on Thanksgiving week than on the same flight during the third week of February. As the seats on a flight sell, yield managers monitor and adjust the seat allocation. If, for instance, the sales are slower than expected, some of the seats might be moved to lower-priced buckets – this shows up as a price drop. As noted above, such price drops can occur at any time before the flight. However, the general trend of price quotes is upward starting from about two to three weeks before the flight departure date.</p> <p>Of course, an average traveler wants to know when he or she should buy the tickets for the next trip. Another important question is where to buy this ticket. Airlines distribute their inventory on their own websites and on several computer distribution systems, meaning that prices can sometimes differ depending on where one looks. We are not entirely sure what precipitates this phenomenon – likely explanations include differences in contracts between the airlines and the distribution systems/travel agents, implying that different travel agents may not have access to the airline’s entire inventory of available prices.</p> <h2>When to book</h2> <p>The airlines’ yield managers start looking at flight bookings about two months before the departure date. This implies that it generally does not pay to book more than two months in advance: studies show that initially the airlines leave the cheapest price buckets empty, and yield managers may move some seats into those buckets if a couple of months before the departure date the flight is emptier than expected. Between two months and about two to three weeks before the flight date, the fare quotes remain mostly flat, with a slight upward trend. However, and perhaps paradoxically, there is a good chance of a price drop during this period. We tend to monitor prices for several days – sometimes up to a week – hoping for a potentially lower quote. It does not always pay off, but sometimes we do manage to save a considerable amount of money.</p> <p>Two to three weeks before the flight date, the price quotes start increasing. This is the time when business travelers start booking. While price drops are still possible, a chance of a price increase is much higher if you wait to book within this time period. This is also the time when one can find significant differences between price quotes, depending on where one looks and what contract they have with the airlines.</p> <p>Thus, if we book a trip earlier than three weeks before the flight date, we tend not to delay the purchase. At the same time, we check quotes from multiple travel agents, or go directly to a site that allows for a quick comparison of prices (such as <a href="https://www.kayak.com">kayak.com</a> or <a href="http://www.skyscanner.net">skyscanner.net</a>). Or check the airline itself.</p> <p>As for answering the original question we posed, here are some simple tips. First, if you have to travel during a peak period, such as Thanksgiving week, it is generally best not to delay buying that ticket. Otherwise, it might pay to monitor the offered prices for some time before committing. The best strategy for booking within the last couple of weeks before the flight, however, is not to delay the purchase, but to try getting quotes from several agents, which is easy to do in the internet 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/34033/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/yuriy-gorodnichenko-144556"><em>Yuriy Gorodnichenko</em></a><em>, Associate Professor of Economics, <a href="https://theconversation.com/institutions/university-of-california-berkeley-754">University of California, Berkeley</a> and <a href="https://theconversation.com/profiles/volodymyr-bilotkach-145437">Volodymyr Bilotkach</a>, Senior Lecturer in Economics, <a href="https://theconversation.com/institutions/newcastle-university-906">Newcastle University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How often should you really weigh yourself?

<p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Few topics are more debated in health than the value of the humble bathroom scale. Some experts advocate daily self-weigh-ins to promote accountability for weight management, particularly when we’re following a diet and exercise program to lose weight.</p> <p>Others suggest ditching self-weigh-ins altogether, arguing they can trigger negative <a href="https://link.springer.com/article/10.1007/s13679-015-0142-2">psychological responses and unhealthy behaviours</a> when we don’t like, or understand, the number we see on the scale.</p> <p>Many, like me, recommend using scales to weigh yourself weekly, even when we’re not trying to lose weight. Here’s why.</p> <h2>1. Weighing weekly helps you manage your weight</h2> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2588640/?tool=pmcentrez&amp;report=abstract">Research</a> confirms regular self-weighing is an effective weight loss and management strategy, primarily because it helps increase awareness of our current weight and any changes.</p> <p>A <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2588640/?tool=pmcentrez&amp;report=abstract">systematic review of 12 studies</a> found participants who weighed themselves weekly or daily over several months lost 1–3 BMI (body mass index) units more and regained less weight than participants who didn’t weight themselves frequently. The weight-loss benefit was evident with weekly weighing; there was no added benefit with daily weighing.</p> <p>Self-weigh-ins are an essential tool for weight management as we age. Adults <a href="https://pubmed.ncbi.nlm.nih.gov/23638485/">tend to gain weight</a> progressively <a href="https://pubmed.ncbi.nlm.nih.gov/8363190/">through middle age</a>. While the average weight gain is typically between <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031938414001528">0.5–1kg per year</a>, this modest accumulation of weight can lead to obesity over time. Weekly weighing and keeping track of the results helps avoid unnecessary weight gain.</p> <p>Tracking our weight can also help identify medical issues early. Dramatic changes in weight can be an early sign of some conditions, including problems with our thyroid, digestion and diabetes.</p> <h2>2. Weekly weighing accounts for normal fluctuations</h2> <p>Our body weight can fluctuate within a single day and across the days of the week. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7192384/">Studies</a> show body weight fluctuates by 0.35% within the week and it’s typically higher after the weekend.</p> <p>Daily and day-to-day body weight fluctuations have several causes, many linked to our body’s water content. The more common causes include:</p> <p><strong>The type of food we’ve consumed</strong></p> <p>When we’ve eaten a dinner higher in carbohydrates, we’ll weigh more the next day. This change is a result of our bodies temporarily carrying more water. We <a href="https://pubmed.ncbi.nlm.nih.gov/25911631/">retain 3–4 grams of water</a> per gram of carbohydrate consumed to store the energy we take from carbs.</p> <p>Our water content also increases when we consume <a href="https://www.ncbi.nlm.nih.gov/books/NBK50952/">foods higher in salt</a>. Our bodies try to maintain a balance of sodium and water. When the concentration of salt in our bloodstream increases, a mechanism is triggered to restore balance by retaining water to dilute the excess salt.</p> <p><strong>Our food intake</strong></p> <p>Whether it’s 30 grams of nuts or 65 grams of lean meat, everything we eat and drink has weight, which increases our body weight temporarily while we digest and metabolise what we’ve consumed.</p> <p>Our weight also tends to be lower first thing in the morning after our food intake has been restricted overnight and higher in the evening after our daily intake of food and drinks.</p> <p><strong>Exercise</strong></p> <p>If we weigh ourselves at the gym after a workout, there’s a good chance we’ll weigh less due to sweat-induced fluid loss. The amount of water lost varies depending on things like our workout intensity and duration, the temperature and humidity, along with our sweat rate and hydration level. On average, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4993146/">we lose 1 litre of sweat</a> during an hour of <a href="https://link.springer.com/article/10.1007/BF00421168">moderate-intensity exercise</a>.</p> <p><strong>Hormonal changes</strong></p> <p><a href="https://theconversation.com/from-energy-levels-to-metabolism-understanding-your-menstrual-cycle-can-be-key-to-achieving-exercise-goals-131561">Fluctuations in hormones</a> within your menstrual cycle can also affect fluid balance. Women may experience <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3154522/">fluid retention</a> and temporarily gain 0.5–2kg of weight at this time. Specifically, the luteal phase, which represents the second half of a woman’s cycle, results in a shift of fluid from your blood plasma to your cells, and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3154522/">bloating</a>.</p> <p><strong>Bowel movements</strong></p> <p>Going to the bathroom can lead to small but immediate weight loss as waste is eliminated from the body. While the amount lost will vary, we generally eliminate <a href="https://pubmed.ncbi.nlm.nih.gov/1333426/">around 100 grams of weight</a> through our daily bowel movements.</p> <p>All of these fluctuations are normal, and they’re not indicative of significant changes in our body fat or muscle mass. However, seeing these fluctuations can lead to unnecessary stress and a fixation with our weight.</p> <h2>3. Weekly weighing avoids scale obsession and weight-loss sabotage</h2> <p>Weighing too frequently can create an obsession with the number on the scales and do more harm than good.</p> <p>Often, our reaction when we see this number not moving in the direction we want or expect is to further restrict our food intake or embark on fad dieting. Along with not being enjoyable or sustainable, fad diets also ultimately increase our weight gain rather than reversing it.</p> <p>This was confirmed in a <a href="https://pubmed.ncbi.nlm.nih.gov/21829159/">long-term study</a> comparing intentional weight loss among more than 4,000 twins. The researchers found the likelihood of becoming overweight by the age of 25 was significantly greater for a twin who dieted to lose 5kg or more. This suggests frequent dieting makes us more susceptible to weight gain and prone to future weight gain.</p> <h2>So what should you do?</h2> <p>Weighing ourselves weekly gives a more accurate measure of our weight trends over time.</p> <p>Aim to weigh yourself on the same day, at the same time and in the same environment each week – for example, first thing every Friday morning when you’re getting ready to take a shower, after you’ve gone to the bathroom, but before you’ve drunk or eaten anything.</p> <p>Use the best quality scales you can afford. Change the batteries regularly and check their accuracy by using a “known” weight – for example, a 10kg weight plate. Place the “known” weight on the scale and check the measurement aligns with the “known” weight.</p> <p>Remember, the number on the scale is just one part of health and weight management. Focusing solely on it can overshadow other indicators, such as <a href="https://theconversation.com/can-you-be-overweight-and-healthy-182219">how your clothes fit</a>. It’s also essential to pay equal attention to how we’re feeling, physically and emotionally.</p> <p>Stop weighing yourself – at any time interval – if it’s triggering anxiety or stress, and get in touch with a health-care professional to discuss this.</p> <hr /> <p><em>At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss.

These vary from a nationwide tax in Iceland to various towns across the US. Some have been in place for a long time (France was the <a href="https://www.impots.gouv.fr/taxe-de-sejour">first in 1910</a>), but most were introduced during the last decade or two.</p> <p>Before the pandemic really struck (and tourism was put on hold), 2020 was described by one newspaper as the <a href="https://www.telegraph.co.uk/travel/news/tourist-tax-amsterdam-venice/">“year of the tourist tax”</a>, as Amsterdam joined an ever-growing list of destinations, which includes Paris, Malta and Cancun, to charge visitors for simply visiting.</p> <p>Introducing these tourist taxes has often been controversial, with industry bodies <a href="https://www.bbc.co.uk/news/uk-wales-62707152">voicing concerns</a> about the potential impacts on the tourist trade.</p> <p>And it appears that the link between such levies and visitor numbers is not simple, with several studies reaching different conclusions. For example, some have suggested that tourism levies have hindered <a href="https://www-sciencedirect-com.bangor.idm.oclc.org/science/article/pii/S0261517704000238">international tourism in the Balearics</a> and <a href="https://journals-sagepub-com.bangor.idm.oclc.org/doi/pdf/10.1177/00472875211053658">the Maldives</a>, and that they may dissuade people from participating in <a href="https://eprints.bournemouth.ac.uk/35087/1/ADEDOYIN%2C%20Festus%20Fatai_Ph.D._2020.pdf">domestic tourism</a>.</p> <p>Yet in one of the world’s most popular tourism spots with a levy, Barcelona, visitor numbers have <a href="https://groupnao.com/wp-content/uploads/2020/11/TOURISM-TAXES-BY-DESIGN-NOV12-2020_rettet-compressed-2.pdf">consistently risen</a>, with hotel guests increasing from 7.1 million in 2013 to 9.5 million in 2019.</p> <p>In fact, the relationship between a visitor levy and tourist flow is so complex that there is no unified view, even within the same country. Italy has been one of the most studied, and results <a href="https://crenos.unica.it/crenosterritorio/sites/default/files/allegati-pubblicazioni-tes/Indagine_Villasimius_Quaderno_Crenos_ISBN.pdf">are inconsistent</a> <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/jtr.2123">there too</a>.</p> <p>Another study, looking at three neighbouring Italian seaside spots finds that only in one destination has the visitor levy <a href="https://www.rivisteweb.it/doi/10.1429/77318">reduced tourist flow</a>. And a study on the Italian cities of Rome, Florence and Padua shows that these cities <a href="https://link-springer-com.bangor.idm.oclc.org/chapter/10.1007/978-3-030-61274-0_23">have not experienced any negative effects</a> either in terms of domestic or international demand.</p> <p>So the impact of tourism taxes on visitor numbers is inconclusive.</p> <p>But what about other effects, such as the potential benefits of spending the revenues raised? As part of an ongoing research project, we looked at seven different destinations in which tourist taxes are levied to look at how the money raised is then spent.</p> <p>For most places, tourism tax revenues were being used to fund marketing and branding – so invested directly into promoting more tourism. The income was also commonly used to fund tourism infrastructure, from public toilets and walking or cycling paths to a multi-billion dollar <a href="https://www.occc.net/About-Us-Media-Relations-Press-Releases/ArticleID/569/Orange%20County%20Board%20Votes%20to%20Approve%20Convention%20Center%20Completion%20with%20Tourist%20Development%20Tax%20Revenues">convention centre</a> in Orange County, Florida.</p> <p>In <a href="https://www.caib.es/sites/impostturisme/en/l/projects/?mcont=95762">the Balearics</a>, revenues tend to go to projects that mitigate the negative impacts of tourism on the environment, culture and society of the islands.

Why you should be wary of charging your phone in an airport

<p dir="ltr">While charging stations at airports can often be life-savings before boarding a flight, it turns out these handy outlets can be leaving you vulnerable. </p> <p dir="ltr">Many people have fought over a spot to charge up your devices at the last minute before embarking on a holiday, but next time you leave home with your phone or laptop needing some more juice, think again. </p> <p dir="ltr">Emily Stallings, co-founder of tech retailer <em><a href="https://www.getcasely.com/">Casely</a></em>, says that by plugging your phone into a power outlet at a public USB charging station, you're at risk of data breaches and malware infection.</p> <p dir="ltr">"If a device gets infected, it could end up leaking sensitive information or even stop working properly," she told <em><a href="https://travel.nine.com.au/latest/charging-phone-at-the-airport-danger-expert/57d141df-33ba-4a50-89e5-26f6f2a0c18d">9Travel</a></em>.</p> <p dir="ltr">These public USB ports have often been compromised by cybercriminals, who then use these unsecured ports to steal sensitive information transmitted between devices.</p> <p dir="ltr">"From personal emails to financial data, the information intercepted through these compromised ports could lead to identity theft, financial loss, and other serious consequences," explains Stallings.</p> <p dir="ltr">The best way to get around this threat, without letting your phone run out of battery, is to pack a portable charging device in your carry-on bag every time you travel.</p> <p dir="ltr">With your own cord and power bank, it's far less likely that any sneaky hackers will be able to access your device's data.</p> <p dir="ltr">Stallings says you can also enable security features such as USB Restricted Mode on your device, for those moments when you're desperate for a charger and have to rely on public ports. </p> <p dir="ltr">"This adds an extra layer of protection against potential data breaches and malware infections when charging from public USB ports."</p> <p dir="ltr">"By activating USB Restricted Mode or similar security features, you restrict data transfer over USB connections, effectively preventing unauthorised access to your device's data while charging in public spaces."</p> <p dir="ltr"><em>Image credits: Shutterstock </em></p>

What you should know before you start chasing bargains at the EOFY sales

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/park-thaichon-175182">Park Thaichon</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a></em></p> <p>What cost-of-living crisis? Millions of Australians are expected to spend <a href="https://www.roymorgan.com/findings/9592-ara-roy-morgan-media-release-eofy-mid-year-sales-2024">A$10.1 billion</a> during the end of financial year (EOFY) sales.</p> <p>Many products, from cars and holiday packages to clothing and white goods will be available at marked down prices over the next few weeks.</p> <p>Clothing and accessories will attract the biggest spend, followed by electronics and technology, household items and decorations and then appliances and white goods.</p> <p>To put the estimated $10.1 billion EOFY spend in perspective, in 2023 Australians spent <a href="https://ecommerce-report.auspost.com.au/">$361 billion on retail goods</a>, with $63.6 billion of that spent online.</p> <p>With such high spending, consumers need to make informed decisions to maximise their savings and avoid pitfalls.</p> <h2>Buyer beware</h2> <p>It is important to understand the return and exchange policies of the different retail stores.</p> <p>Most retailers allow shoppers who change their mind up to 30 days to return and receive a refund or exchange the product. Some may have shorter return periods or may not accept returns on sale items.</p> <p>These items are sometimes referred to as final sales, non-refundable purchases, last-chance deals, no-return sales and clearance items. This means if a customer bought something on sale and later doesn’t want it, they can’t return or exchange it.</p> <p>Some retailers have specific conditions about where items can be returned. For example, in Melbourne <a href="https://www.davidjones.com/return-options">David Jones</a> requires boutique brands to be returned to specific branch locations. For example, items purchased instore from Chanel can only be returned at Elizabeth Street and Bourke Street Mall branches.</p> <p>Other conditions might include <a href="https://www.myer.com.au/content/returns-exchanges">no refunds/no exchanges</a> on large electrical items, furniture or mattresses unless faulty or damaged. Or retailers may only offer instore credit or charge a <a href="https://www.davidjones.com/return-options">25% restocking fee</a> when a customer cancels an order for a large or bulky item.</p> <p>Many retailers, such as streetwear brand <a href="https://www.culturekings.com.au/pages/shipping-returns">Culture Kings</a>, also require a payment if the return process involves shipping.</p> <p>As well as these conditions, retailers require any returned items to be in their original condition and sometimes, their original packaging. Being aware of these policies can help customers make more informed decisions and avoid being stuck with items they don’t want.</p> <h2>What to buy and where to get it</h2> <p>Certain items, such as off-season clothing, electronics and furniture are often discounted during EOFY sales, making it a good time to get them at reduced cost.</p> <p>However, some items, like the latest Playstation or newest smart phone, may not be as heavily discounted and might be better bought at other times of the year.</p> <p>Shoppers should also avoid buying items they are unlikely to use or consume before they expire including perishable goods like food, cosmetics and vitamins.</p> <hr /> <p><iframe id="dnC1Y" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/dnC1Y/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>It’s also important to consider the value of the item and whether the discount offered during sales justifies the purchase, especially for big-ticket items that may require significant storage space or maintenance.</p> <p>Customers should also consider where to buy their items. Online retailers often have competitive prices and a wide selection, but some customers may prefer to see the item before they purchase instore.</p> <p><a href="https://journals.sagepub.com/doi/full/10.1177/14413582231167664">Multi-channel shopping</a> is a combination of both instore and online shopping. It gives customers the flexibility to choose how and where they want to browse and purchase.</p> <p>For example, some customers prefer to touch, feel and try a product instore but then make the purchase online for convenience, taking advantage of any free shipping offers and online discount.</p> <h2>Pressure tactics</h2> <p>It is important to be wary any deceptive tactics to persuade you to buy unwanted products.</p> <p>For example, some stores might use misleading advertising or pressure tactics to convince customers to make purchases with the feeling of fear of missing out (FOMO).</p> <p><a href="https://onlinelibrary.wiley.com/doi/full/10.1111/ijcs.12649?casa_token=271MN72XdP8AAAAA%3AfhYF_2yUJtM7KGv5jvFdXn5UsXQLkMcIM_F6hffYa30QaSdRivjf2mhFX-cr5C7ttCuLl1-e2OFYXBA">Our research found</a> FOMO played a role in panic buying.</p> <p>During the EOFY sales, businesses may try to create a sense of urgency by claiming that items are selling out quickly or prices will increase soon.</p> <p>For example, online sites might state a product is “low in stock”, “151 items have been sold today” or “25 people are watching this item”.</p> <p>By being aware these tactics are intended to lock them into buying, customers can take their time to consider purchases carefully and avoid being swayed into buying things they do not really want or need.</p> <p>Ultimately, the best approach for customers is to plan ahead, research prices and shop around to find the best deals for their needs.</p> <h2>Why we have EOFY sales</h2> <p>The original purpose of the EOFY is to mark the end of a 12-month accounting period for businesses and individuals. EOFY sales help businesses clear out last year’s stock and make way for new.</p> <p>Moving stock also helps to improve the bottom line by converting unsold goods into revenue.</p> <p>If consumers are savvy, they can find ways to make savings while also putting money back into the economy.<!-- Below is The Conversation's page counter tag.

Why you should never take nutrition advice from a centenarian

<p><em><a href="https://theconversation.com/profiles/bradley-elliott-1014864">Bradley Elliott</a>, <a href="https://theconversation.com/institutions/university-of-westminster-916">University of Westminster</a></em></p> <p>It’s a cliche of reporting on people who reach 100 years of age, or even 110, to ask them some variation of the question: “What did you do to live this long?”</p> <p>Inevitably, some interesting and unexpected answer is highlighted. <a href="https://www.theguardian.com/society/2024/apr/05/briton-says-becoming-worlds-oldest-man-at-111-is-pure-luck">Fish and chips</a> every Friday. Drinking a glass of <a href="https://news.sky.com/story/worlds-oldest-man-juan-vicente-perez-dies-aged-114-13107627">strong liquor</a> every day. <a href="https://www.businessinsider.com/susannah-mushatt-jones-loves-bacon-2015-10">Bacon</a> for breakfast every morning. <a href="https://apnews.com/article/health-france-nursing-homes-795c8273f66b61669e93103cc9c25cd0">Wine and chocolate</a>.</p> <p>While a popular news story, this is a relatively meaningless question that doesn’t help us understand why certain people have lived so long. Let me try to explain why, via beautiful buildings, fighter pilots and statistics.</p> <p>In the second world war, Allied statisticians were applying their skills to minimising the number of bombers being shot down by enemy fire. By studying the damage patterns of bombers returning from action, maps could be drawn up of the most frequently damaged parts of aeroplanes so that expensive, heavy armour could be added to these areas.</p> <p>Simple enough, right? Then, along comes statistician Abraham Wald who argues for the exact <a href="https://www.jstor.org/stable/2287454?origin=crossref">opposite point</a>. The planes that they’re studying are all those that did return from combat with extensive damage, but what about those that didn’t return?</p> <p>Wald argues that armour should be added to those places that are undamaged on all the returning planes, as any plane hit in these undamaged areas was shot down, never making it back to be surveyed.</p> <h2>Survivorship bias</h2> <p>This phenomenon is known as survivorship bias, or the cognitive and statistical bias introduced by only counting those that are around to count but ignoring those that haven’t “survived”.</p> <p>You can take these examples to the absurd. Imagine a group of 100 people, all of whom have smoked their entire life. As a group, the smokers would die earlier of cancers, lung disease or heart disease, but one or two might defy the odds and live to 100 years of age. Now imagine the intrepid journalist interviewing the lucky soul on their 100th birthday with that classic question: “What do you attribute your successful ageing to?”</p> <p>“Smoking a pack a day,” says the newly minted centenarian.</p> <p>It seems obvious but survivorship bias is everywhere in society. We can all think of that one famous actor or entrepreneur who succeeded despite adversity, who worked hard, believed in themselves and one day made it. But we never read about or hear about the countless examples of people who tried, gave it their all and never quite made it.</p> <p>That’s not a good media story. But this creates a bias, we primarily hear the successes, never the failures. This bias applies to our perceptions of architecture (mostly great buildings from a given period “survive”), to finances (we often hear examples of people who have succeeded in risky investments, those who fail don’t sell books or self-help plans) and to career plans (“If you work hard, and drop out of college now, you can be a successful athlete like me,” say those who have succeeded).</p> <p>I work with a variety of older people and often include extreme outliers who have lived to extreme ages. We’re currently studying over 65-year-olds who have maintained unusually high levels of exercise into older age and have maintained excellent health.</p> <p>They’re phenomenal examples of older humans, many of them are faster, fitter and stronger than me by many of the measures we perform in the lab, despite being almost twice my age.</p> <p>While we know that their lifelong exercise is associated with their unusually good health into older age, we can’t directly say one causes the other yet. It could be that highly active people are protected against chronic diseases such as cancers, diabetes and heart disease. But it also could be that these people are still active into older age as they’ve not been afflicted by cancers, diabetes or heart disease earlier in their lives.</p> <p>Conversely, there could be some unknown third factor that we’ve not yet identified about these people that both keeps them healthy and separately keeps them exercising.</p> <p>For clarity, there are things that scientists like me will say in carefully caveated, scientific language that will probably help you to live longer. Being very physically active, not eating too much and not smoking are all on that list, along with generally having a positive outlook in life, and of course, picking the right parents and grandparents.</p> <p>Correlation does not equal causation. That point is hammered home relentlessly to students in science degrees. It’s how our brain works, we see a pattern between two variables, and assume they’re linked in some way. But often, like in survivorship bias, we’re not looking at all the data, and so finding patterns where there are none.<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/229159/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/bradley-elliott-1014864">Bradley Elliott</a>, Senior Lecturer in Physiology, <a href="https://theconversation.com/institutions/university-of-westminster-916">University of Westminster</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How risky is turbulence on a plane? How worried should I be?

<p><em><a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>The Singapore Airlines <a href="https://www.abc.net.au/news/2024-05-21/singapore-london-flight-makes-emergency-landing/103876370">turbulence incident</a> that has sadly left one person dead and others hospitalised has made many of us think about the risks of air travel.</p> <p>We’ll hear more in coming days about how the aircraft came to drop so suddenly on its route from London to Singapore earlier this week, injuring passengers and crew, before making an emergency landing in Thailand.</p> <p>But thankfully, these types of incidents <a href="https://www.atsb.gov.au/publications/2014/in-flight-turbulence">are rare</a>, and much <a href="https://www.aihw.gov.au/reports/injury/transport-accidents">less-common</a> than injuries from other types of transport.</p> <p>So why do we sometimes think the risk of getting injured while travelling by plane is higher than it really is?</p> <h2>How common are turbulence injuries?</h2> <p><a href="https://theconversation.com/what-is-air-turbulence-196872">Turbulence</a> <a href="https://www.atsb.gov.au/publications/2014/in-flight-turbulence">is caused by</a> the irregular movement of air, leading to passengers and crew experiencing abrupt sideways and vertical jolts.</p> <p>In the case of the Singapore Airlines flight, this type of turbulence is thought to be a severe example of “<a href="https://www.theguardian.com/business/article/2024/may/21/what-causes-air-turbulence-and-how-worried-should-passengers-be">clear-air turbulence</a>”, which can occur without warning. There are several other types.</p> <p>About 25 in-flight turbulence injuries <a href="https://www.atsb.gov.au/publications/2014/in-flight-turbulence">are reported</a> to the Australian Transport Safety Bureau each year, although it is thought many more are un-reported. Some of these reported injuries are serious, including broken bones and head injuries. Passengers being thrown up and out of their seat during turbulence is one of the most common type of head injury on a plane.</p> <p>Other injuries from turbulence are caused by contact with flying laptops, or other unsecured items.</p> <p>In <a href="https://www.atsb.gov.au/sites/default/files/2023-04/AR-2008-034%20Turbulence%20FactSheet_v2.pdf">one example</a> of clear-air turbulence that came without warning, cabin crew, passengers and meal trolleys hit the ceiling, and landed heavily back on the floor. Serious injuries included bone fractures, lacerations, neck and back strains, a dislocated shoulder and shattered teeth. Almost all of those seriously injured did not have their seat belts fastened.</p> <p>But we need to put this into perspective. In the year to January 2024, there were <a href="https://www.bitre.gov.au/statistics/aviation/international">more than 36 million</a> passengers on international flights to Australia. In the year to February 2024, there were <a href="https://www.bitre.gov.au/statistics/aviation/domestic">more than 58 million</a> passengers on domestic flights.</p> <p>So while such incidents grab the headlines, they are exceedingly rare.</p> <h2>Why do we think flying is riskier than it is?</h2> <p>When we hear about this recent Singapore Airlines incident, it’s entirely natural to have a strong emotional reaction. We might have imagined the terror we might feel if we were on the aircraft at the time.</p> <p>But our emotional response <a href="https://psycnet.apa.org/record/2001-16969-005">alters our perception</a> of the risk and leads us to think these rare incidents are more common than they really are.</p> <p>There is a vast body of literature addressing the <a href="https://theconversation.com/explainer-how-our-understanding-of-risk-is-changing-79501">numerous factors</a> that influence how individuals perceive risk and the cognitive biases we are all subject to that mislead us.</p> <p>Nobel Prize-winning economist <a href="https://www.nobelprize.org/prizes/economic-sciences/2002/kahneman/facts/">Daniel Kahneman</a> covers them in his bestselling book <a href="https://www.penguin.com.au/books/thinking-fast-and-slow-9780141033570">Thinking, Fast and Slow</a>.</p> <p>He describes the way we respond to risks is not rational, but driven by emotion. Kahneman also highlights the fact that our brains are not wired to make sense of extremely small risks. So these types of risks – such as the chance of serious injury or death from in-flight turbulence – are hard for us to make sense of.</p> <p>The more unusual an event is, and this was a very unusual event, Kahneman says the more impact it makes on our psyche and the more likely we are to overestimate the risk.</p> <p>Of course, the more unusual the event, the <a href="https://psycnet.apa.org/record/1999-02435-000">more likely</a> it is for it to be in the media, amplifying this effect.</p> <p>Similarly, the easier it is to <a href="https://www.sciencedirect.com/science/article/abs/pii/0010028573900339">imagine an event</a>, the more it affects our perception and the more likely we are to respond to an event as if it were much more likely to occur.</p> <h2>How can we make sense of the risk?</h2> <p>One way to make sense of activities with small, hard-to-understand risks is by comparing their risks to the risks of more familiar activities.</p> <p>If we do this, the data shows very clearly that it is much <a href="https://www.aihw.gov.au/reports/injury/transport-accidents">more risky</a> to drive a car or ride a motorbike than to travel by plane.</p> <p>While events such as the Singapore Airlines incident are devastating and stir up lots of emotions, it’s important to recognise how our emotions can mislead us to over-estimate the risk of this happening again, or to us.</p> <p>Apart from the stress and anxiety this provokes, overestimating the risks of particular activities may lead us to make bad decisions that actually put us at greater risk of harm.<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/230665/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><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></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How much time should you spend sitting versus standing? New research reveals the perfect mix for optimal health

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/christian-brakenridge-1295221">Christian Brakenridge</a>, <a href="https://theconversation.com/institutions/baker-heart-and-diabetes-institute-974">Baker Heart and Diabetes Institute</a></em></p> <p>People have a pretty intuitive sense of what is healthy – standing is better than sitting, exercise is great for overall health and getting <a href="https://theconversation.com/could-not-getting-enough-sleep-increase-your-risk-of-type-2-diabetes-225179">good sleep is imperative</a>.</p> <p>However, if exercise in the evening may disrupt our sleep, or make us feel the need to be more sedentary to recover, a key question emerges – what is the best way to balance our 24 hours to optimise our health?</p> <p><a href="https://link.springer.com/article/10.1007/s00125-024-06145-0">Our research</a> attempted to answer this for risk factors for heart disease, stroke and diabetes. We found the optimal amount of sleep was 8.3 hours, while for light activity and moderate to vigorous activity, it was best to get 2.2 hours each.</p> <p><iframe id="dw4bx" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/dw4bx/" width="100%" height="400px" frameborder="0"></iframe></p> <h2>Finding the right balance</h2> <p>Current health guidelines recommend you stick to a <a href="https://www.health.gov.au/topics/physical-activity-and-exercise/physical-activity-and-exercise-guidelines-for-all-australians/for-adults-18-to-64-years">sensible regime</a> of moderate-to vigorous-intensity physical activity 2.5–5 hours per week.</p> <p>However <a href="https://doi.org/10.1016/j.jacc.2019.02.031">mounting evidence</a> now <a href="https://doi.org/10.2337/dc14-2073">suggests</a> how you spend your day can have meaningful ramifications for your health. In addition to moderate-to vigorous-intensity physical activity, this means the time you spend sitting, standing, doing light physical activity (such as walking around your house or office) and sleeping.</p> <p>Our research looked at more than 2,000 adults who wore body sensors that could interpret their physical behaviours, for seven days. This gave us a sense of how they spent their average 24 hours.</p> <p>At the start of the study participants had their waist circumference, blood sugar and insulin sensitivity measured. The body sensor and assessment data was matched and analysed then tested against health risk markers — such as a heart disease and stroke risk score — to create a model.</p> <p>Using this model, we fed through thousands of permutations of 24 hours and found the ones with the estimated lowest associations with heart disease risk and blood-glucose levels. This created many optimal mixes of sitting, standing, light and moderate intensity activity.</p> <p>When we looked at waist circumference, blood sugar, insulin sensitivity and a heart disease and stroke risk score, we noted differing optimal time zones. Where those zones mutually overlapped was ascribed the optimal zone for heart disease and diabetes risk.</p> <h2>You’re doing more physical activity than you think</h2> <p>We found light-intensity physical activity (defined as walking less than 100 steps per minute) – such as walking to the water cooler, the bathroom, or strolling casually with friends – had strong associations with glucose control, and especially in people with type 2 diabetes. This light-intensity physical activity is likely accumulated intermittently throughout the day rather than being a purposeful bout of light exercise.</p> <p>Our experimental evidence shows that <a href="https://diabetesjournals.org/care/article/39/6/964/29532/Benefits-for-Type-2-Diabetes-of-Interrupting">interrupting our sitting</a> regularly with light-physical activity (such as taking a 3–5 minute walk every hour) can improve our metabolism, especially so after lunch.</p> <p>While the moderate-to-vigorous physical activity time might seem a quite high, at more than 2 hours a day, we defined it as more than 100 steps per minute. This equates to a brisk walk.</p> <p>It should be noted that these findings are preliminary. This is the first study of heart disease and diabetes risk and the “optimal” 24 hours, and the results will need further confirmation with longer prospective studies.</p> <p>The data is also cross-sectional. This means that the estimates of time use are correlated with the disease risk factors, meaning it’s unclear whether how participants spent their time influences their risk factors or whether those risk factors influence how someone spends their time.</p> <h2>Australia’s adult physical activity guidelines need updating</h2> <p>Australia’s <a href="https://www.health.gov.au/topics/physical-activity-and-exercise/physical-activity-and-exercise-guidelines-for-all-australians/for-adults-18-to-64-years">physical activity guidelines</a> currently only recommend exercise intensity and time. A <a href="https://www.uow.edu.au/media/2023/why-adults-need-to-move-more-stop-sitting-and-sleep-better-.php">new set of guidelines</a> are being developed to incorporate 24-hour movement. Soon Australians will be able to use these guidelines to examine their 24 hours and understand where they can make improvements.</p> <p>While our new research can inform the upcoming guidelines, we should keep in mind that the recommendations are like a north star: something to head towards to improve your health. In principle this means reducing sitting time where possible, increasing standing and light-intensity physical activity, increasing more vigorous intensity physical activity, and aiming for a healthy sleep of 7.5–9 hours per night.</p> <p>Beneficial changes could come in the form of reducing screen time in the evening or opting for an active commute over driving commute, or prioritising an earlier bed time over watching television in the evening.</p> <p>It’s also important to acknowledge these are recommendations for an able adult. We all have different considerations, and above all, movement should be fun.<!-- Below is The Conversation's page counter tag.

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

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

Announcing Kate Middleton’s cancer diagnosis should have been simple. But the palace let it get out of hand

<p><em><a href="https://theconversation.com/profiles/victoria-fielding-236389">Victoria Fielding</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/saira-ali-1522239">Saira Ali</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p>The British royal family is famous for its carefully curated media image. That’s why it was a surprise to see them lose control of the narrative in the wake of what we now know is a serious health crisis befalling Catherine, Princess of Wales (or Kate Middleton as she’s popularly known).</p> <p>It is clear the nearly 1,000-year-old institution of the monarchy and its tradition of “<a href="https://news.northeastern.edu/2024/03/14/kate-middleton-photo-pr-crisis/">never complain, never explain</a>” is being tested by social media and its power to spread rumours and misinformation. The palace’s public relations team has underestimated how difficult it is to manage relationships with social media audiences. Their reactive attempts to rein in speculation has turned Catherine’s health challenge into a PR disaster.</p> <p>Social media, with its lax regulations and freer environment, offers a more open forum for users to say whatever they like about the royals. It’s served as a hotbed for Catherine conspiracies, particularly on TikTok. These theories are as wild as they are ridiculous, from Catherine being a prisoner in the palace to her hiding in <a href="https://www.prdaily.com/kate-middleton-stanley-alabama-retail/">Taylor Swift’s London home</a>.</p> <p>What should have been a simple announcement to a sympathetic public about a popular royal having cancer turned into a spider’s web of competing conspiracy theories across social media. How did it all go so terribly wrong?</p> <h2>I’ve lost track, what happened?</h2> <p>All was well with the Prince and Princess of Wales when they were filmed attending church on Christmas Day. As usual when royals are out in public, the scene was picture perfect with everyone dutifully smiling for the cameras in “<a href="https://www.harpersbazaar.com/celebrity/latest/a46227698/kate-middleton-royal-blue-christmas-day-church-service-prince-william-kids/">co-ordinated</a>” outfits.</p> <p>Two weeks later, Kensington Palace announced Catherine had undergone planned abdominal surgery, with <a href="https://abcnews.go.com/GMA/Culture/princess-kate-hospitalized-after-planned-abdominal-surgery-palace/story?id=106441561">palace sources</a> telling media the surgery had been “successful” and she would need two weeks to recover.</p> <p>On January 29, the palace announced Catherine had returned home to recuperate. <a href="https://www.townandcountrymag.com/society/tradition/a46569739/king-charles-discharged-from-hospital/">Unlike King Charles</a> when he released news of his cancer diagnosis on February 5, Catherine was not photographed leaving hospital. This was the first PR misstep. She had appeared outside hospital soon after giving birth to her three children, but this time she remained uncharacteristically out of the public eye.</p> <p>Almost a month later, when Prince William <a href="https://au.lifestyle.yahoo.com/prince-william-pulls-memorial-godfather-211406977.html?amp;guce_referrer=aHR0cHM6Ly93d3cuZ29vZ2xlLmNvbS8&amp;guce_referrer_sig=AQAAAG6tOzuXsqZXP6G2nLLd-lnWzZhYKHVJ5TJ-w5XCCfgMjerRrR8v1R8unjtcoQTbvPDsVt3mtTcZ_g0os6zwOuEFfMKCh0kfEExvz-dB2FG0uqcy6-GoryjvG99TEhMli66hNZLjLENmMhq1mwoV7GmM0AYezMDsZtZVtONH9C1b&amp;guccounter=2">unexpectedly withdrew</a> from his godfather’s memorial citing “personal reasons”, social media users started asking “Where is Princess Kate?”.</p> <p>Used to a steady stream of content about the royal family, the public were unsurprisingly questioning if there was more to Catherine’s abdominal surgery than they were being told.</p> <p>In a rare reactive move, the palace tried to quell questions about Catherine’s whereabouts by releasing a <a href="https://people.com/palace-responds-kate-middleton-conspiracy-theories-online-surgery-recovery-rare-statement-8602191">statement</a> reiterating that she would not be returning to public duties until Easter.</p> <p>On March 4, US outlet <a href="https://www.tmz.com/2024/03/04/kate-middleton-seen-spotted-public-first-time-mystery-hospitalization/">TMZ published</a> a paparazzi photo of Catherine driving with her mother. Social media audiences asked if it really was Catherine.</p> <p>Over the next week, conspiracy theories about Catherine’s absence reached frenzied levels. To show everything was fine, Kensington Palace released a <a href="https://twitter.com/KensingtonRoyal/status/1766750995445387393?s=20">Mother’s Day photo</a> of Catherine and her children on their social media accounts. Social media users spotted apparently edited flaws and global news agencies announced “<a href="https://apnews.com/article/kate-princess-photo-surgery-ca91acf667c87c6c70a7838347d6d4fb">kill orders</a>”, saying the image had been manipulated. The next day, Catherine <a href="https://twitter.com/KensingtonRoyal/status/1767135566645092616">apologised</a> on social media for editing the photo.</p> <p>Although royals have been <a href="https://www.townandcountrymag.com/society/tradition/a60191061/royal-photoshop-history/">editing their pictures</a> for centuries, it seems particularly digitally naive of the palace’s PR team to release such an obviously edited image into an already cynical social media environment, creating fodder for more conspiracy theories.</p> <p>Mainstream news outlets then joined social media users in asking questions about Catherine’s absence. Although this media attention did not legitimise wild conspiracies, in some ways it fuelled them.</p> <p>Days later, TMZ <a href="https://www.youtube.com/watch?v=erWJNmbrECs">published footage</a> of Catherine and William shopping. At this point in the media chaos, many social media users claimed it was fake.</p> <p>This intense public speculation finally ended on March 23, when Catherine <a href="https://twitter.com/KensingtonRoyal/status/1771235267837321694?s=20">released a video</a> explaining her extended absence after abdominal surgery was caused by the surgeons discovering cancer.</p> <p>During a crisis, the public crave transparency, authenticity, honesty and reassurance. These elements were missing in the royal PR team’s carefully worded statements made directly to mainstream media along with reactive, overly curated social media posts.</p> <p>By providing scant details, the palace seemed to believe they could control public perception. But public image is increasingly difficult to control.</p> <h2>The double-edged sword of social media</h2> <p>After Princess Diana’s death in a paparazzi-chase car accident, privacy laws and <a href="https://time.com/4914324/princess-diana-anniversary-paparazzi-tabloid-media/">media regulations</a> forbade the most invasive breaches of the royal family’s privacy, particularly for her children, princes William and Harry. However, tabloid appetite for uncontrolled access soon returned once the princes became adults.</p> <p>Recently, Harry and his wife Meghan have been involved in <a href="https://www.reuters.com/world/uk/prince-harry-his-many-lawsuits-against-press-2023-12-15/">several lawsuits</a> against media companies over breaches of privacy, including phone hacking.</p> <p>The rise of social media has typically been viewed as a tool that gives royals more control over their image through the curation of their own personal content. Previously, the fact Catherine was the one <a href="https://www.businessinsider.com/kate-middleton-cutest-family-photos-2018-5">taking photos</a> of her children was seen as a sign of authenticity and being down to earth (as much as a princess could be).</p> <p>Yet, social media is both a blessing and a curse for the management of public reputations.</p> <p>The perpetuation of contested facts and theories on social media in the wake of Princess Catherine’s unexplained absence shows how difficult it is to curate a controlled image using social media. Lack of verified information in mainstream media helps fuel speculative flames.</p> <p>While <a href="https://www.thedrum.com/news/2024/03/22/where-the-palace-lost-the-plot-and-what-we-can-learn-about-pr-and-empathy-kategate">PR experts</a> believe it is understandable and appropriate for Catherine and her family to have privacy during this time, more timely, direct and honest communication would have gone a long way to prevent relentless gossip.</p> <p>Once rumours and conspiracies gained momentum, the palace perhaps thought the less information provided, the better. However, silence during a crisis just fuels more speculation because the lack of information makes it look like there is something to hide.</p> <p>Catherine’s personal video announcing her cancer diagnosis helped end the social media frenzy. This shows a simple, clear statement posted by Kensington Palace to social media weeks ago would likely have avoided the PR disaster and provided Catherine the privacy she so clearly needs.</p> <p>The palace is now <a href="https://www.sheknows.com/entertainment/articles/2986509/kate-middleton-cancer-pr-disaster/">being criticised</a> for complicating a situation that was relatively simple in retrospect. Many social media users are also upset Catherine took public blame for the photoshopping incident.</p> <p>Any organisation that deals with the media to maintain positive reputations, including the British monarchy, has no choice but to adapt to all kinds of media, including social media. The long-time practice of keeping calm and carrying on amid controversy and the 24-hour gossip cycle doesn’t work in the era of TikTok, X and YouTube.</p> <p>In the absence of trusted information, social media will do what it does best: take mostly innocuous online chatter and amplify it until it goes viral.<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/226490/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/victoria-fielding-236389">Victoria Fielding</a>, Lecturer, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/saira-ali-1522239">Saira Ali</a>, Senior Lecturer in Media, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

<p><em><a href="https://theconversation.com/profiles/katie-lee-228942">Katie Lee</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/rachel-neale-891731">Rachel Neale</a>, <a href="https://theconversation.com/institutions/qimr-berghofer-medical-research-institute-1811">QIMR Berghofer Medical Research Institute</a></em></p> <p>As we slide of out summer, you might be wondering how careful you need to be about sun exposure. Excessive exposure causes <a href="https://www.cancer.org.au/about-us/policy-and-advocacy/prevention-policy/national-cancer-prevention-policy/skin-cancer-statistics-and-issues/uv-radiation">skin cancer</a>, but sun exposure also has <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">benefits</a>. How do you balance the two?</p> <p>A new <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">position statement</a> from cancer, bone health and other experts <a href="https://www.assc.org.au/wp-content/uploads/2023/01/Sun-Exposure-Summit-PositionStatement_V1.9.pdf">aims to help</a> Australians balance the good and bad effects of sun exposure by taking into account their skin colour, risk of skin cancer, and where they live.</p> <h2>What are the benefits of sunlight?</h2> <p>Ultraviolet (UV) radiation (the wavelengths in sunlight that cause skin cancer) also leads to vitamin D production. <a href="https://dermnetnz.org/topics/vitamin-d">Vitamin D</a> is very important for maintaining strong bones, and is likely to have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">multiple other health benefits</a>.</p> <p>But vitamin D probably isn’t the whole story. Sunshine, including UV radiation, is thought to affect health in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">other ways</a> such as improving our mood and reducing the risk of autoimmune diseases and infections. So for many people, avoiding the sun and taking a vitamin D supplement may not be the best approach.</p> <h2>How much time does it take to make vitamin D?</h2> <p>It’s complicated, but for most people and most of the year across most of Australia, it’s a lot less than you think.</p> <p>The <a href="https://onlinelibrary.wiley.com/doi/10.1111/php.13854">amount of time needed</a> depends on the amount of skin covered by clothing and the intensity of UV radiation (indicated by the UV index). More skin exposed and higher UV index equate to less time needed.</p> <p>Both the UV index and the amount of the year that UV radiation is high increase as you get closer to the equator. In summer, all of Australia is bathed in sunshine. But in winter, opposite ends of the country have <a href="https://onlinelibrary.wiley.com/doi/10.1111/php.13854">very different exposures</a>.</p> <p>In summer, everybody except those with deeply pigmented skin can make enough vitamin D in <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">just five minutes</a> between 9am and 3pm, anywhere in Australia, provided they are wearing shorts and a T-shirt.</p> <p>In winter it’s a different story. In <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">Darwin and Brisbane</a>, 5–10 minutes between 10am and 3pm will do the trick, but in <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">Hobart</a>, factoring in winter clothing, it will take nearly an hour in the middle of the day.</p> <p>Hover your mouse over the lines below to see the length of exposure needed at specific times of day.</p> <p><iframe id="X5szQ" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/X5szQ/" width="100%" height="400px" frameborder="0"></iframe></p> <p>Staying out for longer than needed doesn’t necessarily make more vitamin D, but it <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub#bib25">does cause skin damage</a>.</p> <h2>Hang on, what about those with darker skin?</h2> <p>People with deeply pigmented, brown to black skin accumulate both vitamin D and DNA damage at a much slower rate than people with lighter skin tones.</p> <p>When UV radiation hits a DNA strand, it causes the DNA to become distorted. If the distortion isn’t fixed, it will cause a mistake when the DNA is copied for a new cell, causing a permanent mutation that sometimes leads to cancer.</p> <p>Melanin, the brown pigment in the skin, absorbs UV photons before that can happen, and the high melanin content in the darkest skin tones provides <a href="https://faseb.onlinelibrary.wiley.com/doi/full/10.1096/fj.201701472R">60 times</a> as much UV protection as the small amount in very fair skin.</p> <p>The flip side is the risk of vitamin D deficiency is much higher than the risk of skin cancer.</p> <p>The new statement accounts for this by putting people into <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">three groups</a> based on their risk of skin cancer, with specialised advice for each group.</p> <h2>Highest skin cancer risk</h2> <p>This includes people with very pale skin that burns easily and tans minimally, but also people with darker white or olive skin who can tan easily but have extra skin cancer risk factors because they:</p> <ul> <li>have had <strong>skin cancer</strong> before</li> <li>have a <strong>family history</strong> of melanomas</li> <li>have many <strong>moles</strong></li> <li>are taking <strong>immunosuppressant</strong> medications.</li> </ul> <p>For these people, the harms of sun exposure almost certainly <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">outweigh the benefits</a>.</p> <p>These people should wear sunscreen every day the <a href="https://www.arpansa.gov.au/our-services/monitoring/ultraviolet-radiation-monitoring/ultraviolet-radiation-index">UV index</a> is forecast to get to <a href="https://www.assc.org.au/peak-health-bodies-recommend-new-approach-to-sunscreen-use/">three or more</a>, and use the <a href="https://www.cancer.org.au/cancer-information/causes-and-prevention/sun-safety/be-sunsmart">five sunsmart steps</a> whenever the UV index is above three:</p> <ul> <li><strong>slip</strong> on clothing covering as much of the body as possible</li> <li><strong>slop</strong> on SPF30+ sunscreen on areas that can’t be covered up</li> <li><strong>slap</strong> on a hat</li> <li><strong>seek</strong> shade</li> <li><strong>slide</strong> on sunglasses.</li> </ul> <p>They shouldn’t spend time outdoors deliberately to make vitamin D, but should discuss vitamin D supplements with their doctor.</p> <h2>Intermediate skin cancer risk</h2> <p>This means people with dark white/olive skin that sometimes burns but tans easily, and who don’t have other skin cancer risk factors.</p> <p>These people should still apply sunscreen as part of their usual routine on all days when the UV index is forecast to get to <a href="https://www.assc.org.au/peak-health-bodies-recommend-new-approach-to-sunscreen-use/">three or more</a>, but they can spend enough time outdoors to get a “dose” of vitamin D on most days of the week.</p> <p>Once the time needed for their vitamin D dose is up, they should also use the <a href="https://www.cancer.org.au/cancer-information/causes-and-prevention/sun-safety/be-sunsmart">slip-slop-slap-seek-slide</a> steps to avoid accumulating DNA damage.</p> <p>If they’re unable to do this because of health or lifestyle factors, like being housebound, working night shifts, or always covering up with clothing, they should see their doctor about whether they need vitamin D supplements.</p> <h2>Lowest skin cancer risk</h2> <p>This covers people with deeply pigmented brown to black skin that rarely or never burns.</p> <p>These people can <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub#bib14">safely spend enough time outdoors</a> to make vitamin D and get the other benefits of sunshine. But because more time is needed, it can be difficult, particularly when the weather is cold. Vitamin D supplements might be needed.</p> <p>They don’t need to routinely protect their skin, but might need to <a href="https://www.cancer.org.au/cancer-information/causes-and-prevention/sun-safety/be-sunsmart">slip-slop-slap-seek-slide</a> if they are outdoors for more than two hours.</p> <h2>How do I get the feel-good effects of sunshine?</h2> <p>Spending time outdoors in the early morning is the best way to get the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">feel-good effects</a> of sunshine. An early morning walk is a great idea for all of us, but it won’t make vitamin D.<!-- Below is The Conversation's page counter tag.

Should you be concerned about flying on Boeing planes?

<p><em><a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p>The American aerospace giant Boeing has been synonymous with safe air travel for decades. Since the 1990s, Boeing and its European competitor Airbus have dominated the market for large passenger jets.</p> <p>But this year, Boeing has been in the news for all the wrong reasons. In January, an emergency door plug <a href="https://www.seattletimes.com/business/boeing-aerospace/alaska-airlines-let-boeing-max-fly-despite-warning-signals">blew off a Boeing 737 MAX</a> in mid flight, triggering an investigation from United States federal regulators.</p> <p>More recently, we have seen a Boeing plane lose a tyre while taking off, another flight turned back as the plane was leaking fluid, an apparent engine fire, a landing gear collapse, a stuck rudder pedal, and a plane “dropping” in flight and <a href="https://theconversation.com/latam-flight-800-just-dropped-in-mid-flight-injuring-dozens-an-expert-explores-what-happened-and-how-to-keep-yourself-safe-225554">injuring dozens of passengers</a>. A Boeing engineer who had raised concerns regarding quality control during the manufacturing process on the company’s 787 and 737 MAX planes also <a href="https://www.bbc.com/news/business-68534703">died earlier this week</a>, apparently of a self-inflicted gunshot wound.</p> <p>As members of the travelling public, should we be concerned? Well, yes and no.</p> <h2>Many problems, but not all can be blamed on Boeing</h2> <p>The recent parade of events has certainly been dramatic – but not all of them can be blamed on Boeing. Five incidents occurred on aircraft owned and operated by United Airlines and were related to factors outside the manufacturer’s control, like maintenance issues, potential foreign object debris, and possible human error.</p> <p>A <a href="https://www.independent.co.uk/travel/news-and-advice/united-airlines-plane-tire-blowout-boeing-b2509241.html">United Airlines 777</a> flying from San Francisco to Japan lost a tyre on takeoff, a maintenance issue not related to Boeing. The aircraft landed safely in Los Angeles.</p> <p>A <a href="https://www.mercurynews.com/2024/03/12/united-airlines-reports-fifth-flight-incident-in-a-week-as-jet-turns-back-due-to-maintenance-issue/">United Airlines flight from Sydney</a> to Los Angeles had to return to Sydney due to a “maintenance issue” after a fluid was seen leaking from the aircraft on departure.</p> <p>A <a href="https://www.nbcnews.com/news/us-news/passenger-video-shows-flames-shoot-united-airlines-engine-midflight-rcna142217">United Airlines 737-900</a> flying from Texas to Florida ended up with some plastic bubble wrap in the engine, causing a suspected <a href="https://skybrary.aero/articles/compressor-stall#:%7E:text=Compressor%20stalls%20cause%20the%20air,dirty%20or%20contaminated%20compressor%20components">compressor stall</a>. This is a disruption of air flow to an operating engine, making it “backfire” and emit flames.</p> <p>A <a href="https://simpleflying.com/united-boeing-737-max-houston-runway-incident/">United Airlines 737 Max</a> flying from Tennessee to Texas suffered a gear collapse after a normal landing. The pilot continued to the end of the runway before exiting onto a taxiway – possibly at too high a speed – and the aircraft ended up in the grass and the left main landing gear collapsed.</p> <p>The fifth event occurred on a <a href="https://www.nbcnews.com/news/us-news/another-boeing-max-mishap-ntsb-probes-stuck-rudder-pedals-united-airli-rcna142286">United Airlines 737-8</a> flight from the Bahamas to New Jersey. The pilots reported that the rudder pedals, which control the left and right movement of the aircraft in flight, were stuck in the neutral position during landing.</p> <h2>Manufacturing quality concerns</h2> <p>The <a href="https://www.seattletimes.com/business/boeing-aerospace/alaska-airlines-let-boeing-max-fly-despite-warning-signals">exit door plug failure in January</a> occurred on an Alaska Airlines flight. US regulators are currently investigating Boeing’s <a href="https://www.vox.com/money/24052245/boeing-corporate-culture-737-airplane-safety-door-plug">manufacturing quality assurance</a> as a result.</p> <p>The door plug was installed by a Boeing subcontractor called Spirit AeroSystem. The door plug bolts were not properly secured and the plug door fell off in flight. The same aircraft had a series of pressurisation alarms on two previous flights, and was scheduled for a maintenance inspection at the completion of the flight.</p> <p>Spirit got its start after Boeing shut down its own manufacturing operations in Kansas and Oklahoma, and Boeing is now in the process of <a href="https://www.cnbc.com/2024/03/01/spirit-aerosystems-boeing.html">buying the company</a> to improve quality oversight. Spirit currently works with Airbus, as well, though that may change.</p> <h2>What changed at Boeing</h2> <p>Critics say the <a href="https://www.washingtonpost.com/business/2024/03/12/boeing-whistleblower-death-plane-issues/">culture at Boeing has changed</a> since Airbus became a major competitor in the early 2000s. The company has been accused of shifting its focus to profit at the expense of quality engineering.</p> <p>Former staff have raised concerns over tight production schedules, which increased the pressure on employees to finish the aircraft. This caused many engineers to question the process, and the US Federal Aviation Administration (FAA) to fine Boeing for lapses in quality oversight after tools and debris were found on aircraft being inspected.</p> <p>Several employees have testified before US Congress on the production issues regarding quality control. Based on the congressional findings, the FAA began to inspect Boeing’s processes more closely.</p> <p>Several Boeing employees noted there was a high staff turnover rate during the COVID pandemic. This is not unique to Boeing, as all manufacturing processes and airline maintenance facilities around the globe were also hit with high turnover.</p> <p>As a result, there is an acute shortage of qualified maintenance engineers, as well as pilots. These shortages have created several issues with the airline industry successfully returning to the <a href="https://www.aviationbusinessnews.com/mro/critical-shortage-of-engineers-means-looming-crisis-for-aviation-warns-aeroprofessional/">pre-pandemic levels</a> of 2019. Airlines and maintenance training centres around the globe are working hard to train replacements, but this takes time as one cannot become a qualified engineer or airline pilot overnight.</p> <p>So, is it still safe to fly on Boeing planes? Yes it is. Despite dramatic incidents in the news and social media posts <a href="https://twitter.com/DaveMcNamee3000/status/1767636549288824990">poking fun at the company</a>, air travel is still extremely safe, and that includes Boeing.</p> <p>We can expect these issues with Boeing planes now will be corrected. The financial impact has been significant – so even a profit-driven company will demand change.<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/225675/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, Professor/Head of Aviation, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Trouble

Why you should travel solo this summer

<p><em><a href="https://theconversation.com/profiles/claire-mccamley-446927">Claire McCamley</a>, <a href="https://theconversation.com/institutions/university-of-huddersfield-1226">University of Huddersfield</a></em></p> <p>When you think about booking a summer holiday, you might think of trips with partners, friends or family. The idea of going on holiday alone can be daunting, or even unappealing. It raises all kinds of questions – who will you talk to? Who will you eat with? Will you be safe?</p> <p>There has long been a <a href="https://www.tandfonline.com/doi/abs/10.1080/0267257X.2015.1073170?journalCode=rjmm20">stigma against solo consumption</a>. Societal norms encourage us to be with someone – leisure experiences are billed as something to <a href="https://www.emerald.com/insight/content/doi/10.1108/IJCHM-06-2019-0584/full/pdf?title=dining-alone-improving-the-experience-of-solo-restaurant-goers">share with others</a>. There may also be a level of guilt or self-indulgence associated with solo travel, feeling as if you are shirking responsibility or abandoning time with family.</p> <p>An increase in <a href="https://www.euromonitor.com/article/single-person-households-to-record-128-percent-growth-by-2030">single-person households</a>, however, means the hospitality industry is now serving solo consumers in addition to families and couples. The continuously <a href="https://www.forbes.com/sites/adigaskell/2020/05/11/is-a-blurred-work-life-balance-the-new-normal/?sh=5c9db6341813">blurred line</a> between work and play, particularly for Millennials and younger generations, makes it easier to work remotely or travel as part of our jobs. We are more transient than ever, and have more opportunities to work and travel alone without feeling completely disconnected from the rest of our lives.</p> <p>In recent years, people have been <a href="https://www.telegraph.co.uk/travel/comment/whats-behind-the-rise-in-solo-travel/">increasingly</a> travelling alone – including younger vacationers. They also share their experiences to a large audience on social media – the hashtag #SoloTravel has over 7 million posts associated with it on Instagram. Solo travellers are taking part in the growing <a href="https://www.futuresplatform.com/blog/solo-economy-new-consumption-patterns">solo economy</a> – new products and services targeting the lone consumer.</p> <p>Hotels, <a href="https://www.ncl.com/uk/en/freestyle-cruise/solo-cruising">cruises</a>, restaurants, tourism <a href="https://www.flashpack.com/">companies</a> and festivals are showing how design, staff and technology can be tailored to accommodate – and even encourage – solo consumption in travel. <a href="https://journals.sagepub.com/doi/10.1177/14705931211017184">Our research</a> into the experience of solo consumers in coffee shops offers insight into how solo consumption can be as pleasurable and fulfilling as going with a partner or friend. Through <a href="https://www.research.ucsb.edu/sites/default/files/RD/docs/FREEWRITING-by-Peter-Elbow.pdf">freewriting</a> exercises, these consumers shared their own experiences. Their words offer some reasons you should try it too.</p> <h2>Be together, alone</h2> <p>Our research participants highlighted key factors that help them enjoy their solo experience – high seats and window views allowing them to sit back and observe others’ lives without any direct interaction or connection. You don’t need to arrive with others to feel part of a social environment. Alone in a crowded square or on a busy beach, the proximity of other people and their conversations can be a source of comfort, distraction or even entertainment.</p> <blockquote> <p>The seat is important -– I like the window especially a stool and “shelf” table facing out … I see people, imagine their lives, see cars and life pass by. I watch other customers, I watch the street out the window, the cliché of “watching the world pass by”. The setting, context and environment of the café are important to that moment of pause.</p> </blockquote> <h2>Take time for yourself</h2> <p>Being alone can be a <a href="https://journals.sagepub.com/doi/pdf/10.1177/14705931211017184">therapeutic experience</a>, a time to process thoughts, feelings and emotions and leave you ready to tackle the world again. Perhaps take time to write, draw or practice another creative activity in your own time. Bask in your own thoughts without feeling pressure to please anyone else or force a conversation.</p> <blockquote> <p>Sitting alone with my thoughts can be a comforting experience; picking a seat, getting comfy…I can find silence with my thoughts and don’t feel any pressure to act for anybody or involve myself in a conversation that doesn’t interest me.</p> </blockquote> <h2>Get out of your comfort zone</h2> <p>Being able to do your own thing, without needing to consider others can be relaxing and can also give you the opportunity to do something you’ve never done before, free of judgement. You might want to go to some sort of class, shop or have a complete chill-out day.</p> <p>Findings from our research indicate that time spent doing things alone can relieve some of the pressures that companions can bring. Alone time gives you the space to experience things in your own time and take in your surroundings without distraction. In doing this, you may find yourself in new situations, away from your comfort zone – an energising and enthralling experience.</p> <h2>Embrace solo traveller culture</h2> <p>Solo travellers have their <a href="https://www.sciencedirect.com/science/article/pii/S0278431921002516">own way of doing things</a>, they have a shared behaviour and process and often become a collective in themselves. They acknowledge the process of travelling alone and respect others doing the same, and may even seek out spaces to be alone, together. Solo travellers can engage in a shared experience and dialogue while maintaining their own individualism – helping each other when needed, but also leave one another alone.</p> <blockquote> <p>We search for places where we feel we fit … We are happy to smile at one another. We don’t need to chat to engage. We are happy on our own with a coffee. I am amongst my tribe.<!-- Below is The Conversation's page counter tag.
