What will Earth look like if all its land ice melts? Here's your answer.

Climate change isn't pretty.

A map of the United States post land-ice melt.

Land ice: We got a lot of it. Considering the two largest ice sheets on earth — the one on Antarctica and the one on Greenland — extend more than 6 million square miles combined ... yeah, we're talkin' a lot of ice. But what if it was all just ... gone? Not like gone gone, but melted?

If all of earth's land ice melted, it would be nothing short of disastrous. And that's putting it lightly. This video by Business Insider Science (seen below) depicts exactly what our coastlines would look like if all the land ice melted. And spoiler alert: It isn't great. Lots of European cities like, Brussels and Venice, would be basically underwater.

In Africa and the Middle East? Dakar, Accra, Jeddah — gone.

Millions of people in Asia, in cities like Mumbai, Beijing, and Tokyo, would be uprooted and have to move inland.

South America would say goodbye to cities like Rio de Janeiro and Buenos Aires.

And in the U.S., we'd watch places like Houston, San Francisco, and New York City — not to mention the entire state of Florida — slowly disappear into the sea.

Business Insider based these visuals off National Geographic's estimation that sea levels will rise 216 feet (!) if all of earth's land ice melted into our oceans.

There's even a tool where you can take a detailed look at how your community could be affected by rising seas, for better or worse.

Although ... looking at these maps, it's hard to imagine "for better" is a likely outcome for many of us.

Much of America's most populated regions would be severely affected by rising sea levels, as you'll notice exploring the map, created by Alex Tingle using data provided by NASA.

Take, for instance, the West Coast. (Goodbye, San Fran!)

Or the East Coast. (See ya, Philly!)

And the Gulf Coast. (RIP, Bourbon Street!)

I bring up the topic not just for funsies, of course, but because the maps above are real possibilities.

How? Climate change.

As we continue to burn fossil fuels for energy and emit carbon into our atmosphere, the planet gets warmer and warmer. And that, ladies and gentlemen, means melted ice.

A study published this past September by researchers in the U.S., U.K., and Germany found that if we don't change our ways, there's definitely enough fossil fuel resources available for us to completely melt the Antarctic ice sheet.

Basically, the self-inflicted disaster you see above is certainly within the realm of possibility.

"This would not happen overnight, but the mind-boggling point is that our actions today are changing the face of planet Earth as we know it and will continue to do so for tens of thousands of years to come," said lead author of the study Ricarda Winkelmann, of the Potsdam Institute for Climate Impact Research.

If we want to stop this from happening," she says, "we need to keep coal, gas, and oil in the ground."

The good news? Most of our coastlines are still intact! And they can stay that way, too — if we act now.

World leaders are finallystarting to treat climate change like the global crisis that it is — and you can help get the point across to them, too.

True

When Rachel Heimke was seven, she realized what she wanted to do for the rest of her life. Little did she know a $40,000 BigFuture Scholarship would help her pursue her dreams.

Heimke and her parents were living an unconventional lifestyle, to say the least. The summer after she completed first grade, she and her parents boarded a sailboat and sailed from their hometown in Alaska down the Pacific Coast. The family would spend the next two years traveling on the water, passing Mexico and then sailing across the world to Australia before returning home. It was on the sailboat, watching whales and dolphins breach the water under their boat, that Heimke realized her life’s purpose.

“I was really obsessed with these little porpoises called Vaquitta, who only live in one tiny area of water off the coast of Mexico,” she recalled. “When I learned about them as a kid, there were only 22 left in the wild. Now, there are only ten.” Despite her interest, Heimke was never able to actually see any Vaquitta on her trip, both because of their inherent shyness and because they were so critically endangered due to detrimental fishing policies in the area. “That was my wakeup call,” she says. “I’ll probably never be able to see this porpoise, and I don’t want that to be true of other species.”

Now a young woman of 23, Heimke is realizing her childhood dream of ocean conservation by recently graduating with a Bachelor’s degree in ocean sciences and enrolling in a grad program in Canada to study science communication. Heimke is well on her way to achieving her childhood dream—but she acknowledges that none of this would have been possible without her ocean adventures as a child, the support of her parents, and significant financial support.

At 18, when Heimke was deciding where to study ocean sciences, she stumbled upon an opportunity from BigFuture, College Board's free college and career planning site. The opportunity was the BigFuture Scholarship, which provided students the chance to win a $40,000 scholarship by completing six action items on the website. Heimke was intrigued, since she didn’t need to provide an essay, her GPA, or any test scores to enter. Her eligibility was also not tied to citizenship status or family income, so she decided to give it a shot.

“One of the action items was just going on the BigFuture site and creating a list of colleges I was interested in,” said Heimke. Another item required her to apply for financial aid through FAFSA—something Heimke was planning to do anyway. Every completed action item gave students more chances to win the scholarship, so Heimke completed all six action items quickly.

Months later, Heimke’s parents ushered her over to a call over Zoom, where she met a BigFuture representative who had some surprising news: She was one of 25 students who had won the $40,000 BigFuture college scholarship. Each year she would receive $10,000 in scholarship funding, which would cover her entire tuition bill for all four years of schooling.

“That experience taught me that it’s really important to not give up on your goals and just go for opportunities,” said Heimke. “I never thought I would win anything, but I’ve learned it's worth applying anyway. Even a small scholarship of $1,000 can pay your rent for a month,” she said. “And If you write an essay that takes an hour and you win $5,000, that’s probably the most money per hour you’ll ever make in your life.”

The tuition money made it possible for her to attend college, and for her to apply to graduate school immediately afterward without any financial burdens.

“Now that I’m in graduate school and paying for rent and a phone bill and graduate school tuition, it’s truly a blessing to not have student loan debt on top of that,” Heimke said. Because of the BigFuture scholarship, Heimke doesn’t need to pay for her graduate program either—she’s able to fund her education with the money her parents saved by not having to pay for her undergraduate degree.

One of the biggest blessings, Heimke said, was not needing to delay graduate school to work or find extra funds. With climate change worsening, entering the workforce becomes increasingly important over time.

“I’m not sure exactly what I’ll do with my degrees, but I hope to have a lot of different jobs that ultimately will work toward saving our ocean,” she said.

As a child, witnessing marine life up close and personal was life-changing. Heimke’s goal is for future generations to have that experience, as she did.

Three American tourists enjoying the sights.


One of the most interesting things about traveling the world is noticing how people from your country are a bit different from the place you’re visiting. In America, you’re mostly around fellow countrymen so it’s hard to notice the things that make us stand out.

But when you travel abroad, you quickly notice that no matter how hard you try to blend in, there are a lot of dead giveaways that show people you’re from the States that go way beyond your accent.


A Reddit user named ILoveTallWomen asked the online forum, “Non-Americans of Reddit, what is a dead giveaway that somebody is American?” to see what they think makes us stand out. “I'm not American and am curious about what other foreigners think,” they added.

There was one answer that people in the thread repeated over and over again—Americans are very friendly people.

Countless commenters noted that Americans will approach anyone and start up a conversation. As a person from the U.S., I think that’s a positive stereotype. There’s nothing wrong with being overly friendly.

​People also noted that Americans tend to carry themselves with a lot of confidence and have an abundance of infectious enthusiasm.

On the negative side of things, a lot of people also noted that Americans are loud and have questionable fashion sense. We stand out abroad because we love staying comfortable by wearing white socks and sneakers on just about any occasion.

Maybe we’re happy because our feet don’t hurt?

Here are 17 of the best responses to the dead giveaways that someone is American.

Upworthy Podcast: Dead Giveaways Someone is American

On a recent episode of Upworthy Weekly, hosts Alison Rosen and Tod Perry discuss the internet's hottest, most uplifting and most amusing topics, including dead giveaways a traveler is American.

1.

The most popular poster shared a list:

  • Wearing sneakers with anything
  • Big smiles, firm handshakes
  • Lots of Northface products
  • Renting Segways for sightseeing tours (sometimes using those on cobblestone)
  • Using big adjectives generously ("Wow, your aunt's kidney stones sound awesome!", "This Euroshopper beer tastes great!")
  • Clapping and cheering
  • Telling one's whole life story within 15 minutes of meeting them
  • Loving stories and narratives in general (which makes them fun companions) — [Deleted]

"Apart from the accent? Mostly its the 'prepared for anything' look they have about them (fanny pack, backpack, bottled water, camera pouch) compared to various other tourists - Asians tend to herd together for safety, while Europeans vary between blend-right-in Scandinavian to designer-brands-everywhere French and traffic-laws-are-for-others Italian. But Americans are the only ones who seem to view a perfectly civilised, modern city like some kind of uncharted jungle that doesn't have places to shelter in the rain or buy cheap bottled water." — Yorkshire_Pudden

3.

"Incredibly loud but incredibly friendly." — kevio17

4.

"I asked my wife (Japanese) she said 'In Japan I can spot Americans by the way they dress. Compared to Europeans, Americans tend to lack fashion sense.'" — RegionFree

5.

"When you can hear them before you see them." — C1t!zen_Erased

6.

"'On the streets they are instantly recognizable. They walk in an ugly indifferent manner, usually with their hands in their pockets. Or they're leaning against a pole or wall with a newspaper in their hand and gum in their mouth. According to the people who met them they are more human than the English, for example, whenever someone needs help they do it quicker and better than the English.' — My Grandpa in the Netherlands. In a letter to his sister. June 4th 1945." — MidnightWineRed

7.

"North Face jackets. I went to college in the US (I'm not American) and when I went home for my first winter break wearing my brand new North Face jacket my friend asked me if I was given American citizenship with the purchase." — merbonobo

8.

"I'm English, but I've lived here for 14 years. It's pretty obvious just from your demeanour. Americans generally are more confident in the way they present themselves, most other countries tend to be more reserved. Walk into a room full of different nationalities, I guarantee the American person will be the first to introduce themselves. It's a confidence thing, and I admire it." — zerbey

9.

"When I was visiting Germany in college, a girl said to me, 'Do you know how I know you're an American? You wear white socks.' Needless to say, I haven't worn white socks since." — ars3nal

10.

"We (Americans) describe distances in driving time, as opposed to miles or kilometers. My European relatives always make fun of me for having no clue how far away the next town is, but knowing exactly how long it takes to get there." — hbombs86

11.

"Canadian here...the dead giveaway is when they call me 'honey' or 'sweetie' or 'darling.' I fucking love Americans and I love those terms of endearment!" — AraEnzeru

12.

"Dead giveaway: They're surprised we can drink a beer (or any alcohol) in public in my country." — P1r4nha

13.

"European here ... there's a noticeable trend among Americans to wear jeans, t-shirts, and hooded sweaters when they're abroad. Lots of branded goods too (North Face, A&F, Hollister, Ed Hardy mostly). And in summer, a great percentage of the cargo-shorts-wearers are Americans. But among all that, visible tattoos on otherwise 'normal-looking' people (i.e. not looking like street thugs) are a common indicator too. Americans love tats." — I_AM_A_IDIOT_AMA

14.

"In WWII, my grandpa's company had a problem with German spies. At night the guards could not tell if intruders were returning patrols or enemy soldiers; especially since the spies spoke with flawless American accents. Before opening the gates, they tried asking questions like "What's the capital of Nebraska?" but it didn't always work since the Germans were highly trained and could answer most of the trivia questions. Finally, they stumbled upon a simple but effective test. They would ask them to sing the 4th verse of the Star-Spangled Banner. He told me 'If they start singing, then you shoot 'em. No American knows the 4th verse.' Turns out the whole song had been included in one of the German espionage training manuals." -- [Deleted]

"They ask you what you do." — Askalotl

16.

"They say 'like' a lot and seem to start sentences with 'so' for no apparent reason. Good bunch, though." — [Deleted]

5 ways people with perpetually tidy homes think differently than the rest of us

For some people, these mindsets and habits are intuitive, but they can also be learned.

Tidy people have a different way of looking at things.

Confession: I am not a neat freak, but I've always aspired to be one. I love neat and tidy spaces and envy those who have a natural knack for keeping their homes perpetually guest-ready. Because I live in a normal-messy home, I appreciate it when people say "No one's house is tidy all the time!" but I also know it's not true. There are people with always-tidy houses. I personally know multiple people whose homes never, ever devolve into cluttered chaos, whose kitchen sinks are always free of dishes, whose tables are never cluttered with stuff and whose master bedrooms look like hotel rooms.

Knowing that it is possible, I've spent years observing my naturally neat friends and family to understand what gives them the seemingly superhuman ability to keep their homes clean 24/7. As one might assume, some of it comes down to a fastidiousness and rigid adherence to routines that some of us simply do not possess. Some of it has to do with how often people are home and how much their home actually gets used. However, those things aside, I've figured out handful of "secrets"—minor habits and mindsets—that we messier folks who yearn to be neater can glean from the naturally tidy.

Messy people think of 'cleaning up' as a separate task. Neat people see it as an inherent part of every activity.

Though it's largely unconscious, we all have ways of thinking through completing any activity, from first step to last step. Take eating, for example. For a naturally messier person, "eating" starts with preparing the food and ends with swallowing your last bite. Cleaning up is not an inherent part of the eating process—it's seen as something separate, an activity that has its own beginning and end, its own time frame, its own energy expenditure, etc.

For a naturally neat person, however, eating means preparing the food, eating the food, and then cleaning up whatever mess you made. That's the whole cycle of eating. When you see cleaning up as part of the eating process, eating doesn't "end" until the dishes are finished and the kitchen is clean. Without cleaning up, the eating activity is simply incomplete.

For some people, this sound like a "duh" revelation. For some of us, it's a life-changing mindset shift.

Messy folks tend to overestimate how much time cleanup takes. Neat people don't.

Struggling to accurately estimate how much time a task will take is called "time blindness," and it's a common ADHD trait. But even those of us without ADHD can misjudge how long a task will take and form habits around our erroneous assumptions or perceptions.

For instance, I used to put off unloading the dishwasher because it seemed like a huge chore. All those dishes having to go to all those different cabinets—surely that was something that took a significant chunk of time to do. My brain had it labeled as a "big task" and therefore something I needed to carve out time for.

Then I timed myself doing it one day. Not rushing at all, just casually unloading a full dishwasher. It took less than 3 minutes, which was a fraction of the amount of time my brain had assigned to the task. Did I feel silly having subconsciously made a mountain out of a molehill? Yes. Did finding out it only took 3 minutes change how I viewed that chore and make it so I didn't procrastinate it anymore? Also yes.

Neat people don't put off small cleaning/tidying tasks that they know only take a minute or two. Messy people can utilize timers to help them figure out what those are, because surprisingly, mosts tasks don't take as long as you think they will.

Messy people think of cleaning as all or nothing. Neat people utilize tiny time chunks for mini maintenance.

A messy person will pop something in the microwave for two minutes and then zone out or stare at it while it cooks. A neat person will pop something in the microwave and then use that two minutes to wipe down the counter, unload the dishwasher, or sweep the kitchen floor. They'll fold laundry while watching a show and go put it away during a commercial break. They utilize small snippets of time to do little cleaning tasks, which all add up to maintaining a neat and tidy space without having to take big chunks of time to organize or clean.

Messier folks tend to overlook little messes here and there, so they build up until suddenly there's an overwhelming mess to deal with. It helps to think of cleaning and tidying not as one big chore that is either done or not done, but rather as as a conglomeration of tiny tasks that can be done any time you have a minute or two. Eventually, using tiny time chunks to mini-clean becomes habitual.

Mess makers set things down. Neat people put things back.

"Clean up as you go" is a mantra to internalize if you aspire to have a perpetually neat home. If a neat person is baking, they will take out an ingredient, measure what they need, then put that ingredient back where they got it. They do this every time, so when the baked good gets put in the oven, all that's left to do is clean the dishes they used in prep (which is, of course, seen as an inherent part of the baking task). And this isn't just in the kitchen. They do the same thing with their toiletries in the bathroom, their clothes when choosing an outfit, etc. Everything gets put back rather than put down, preventing a mess from the get go.

person putting peanut butter in a cabinetNeat people put things away instead of putting them down.Photo credit: Canva

If a messy person is baking, they'll take out an ingredient, measure what they need, and then set the ingredient down on the counter. Once the baked good gets put in the oven, there's then a whole counter full of ingredients and dish mess to clean up. And because "cleaning up" is seen as a separate task, there's a gearing up of energy that's required as well as a separate time commitment, which makes procrastination more likely.

The key here is to recognize that putting things back where you got them really doesn't take any more time than setting them down but saves tons of time and work later.

Messy people have more things than places. Neat people have more places than things.

"A place for everything and everything in its place" is a mantra that neat people live by religiously and messy folks may not even realize is possible. If a neat person doesn't have a place for something, they find one or make one by getting rid of something else. If a mess person doesn't have a place for something, it sits on a table or countertop or entryway or some other placeholder for an indeterminate amount of time, often moving from surface to surface before eventually being shoved in a drawer or closet to be dealt with later.

Part of living like a neat person is being honest with yourself about the space you have and embracing inflow and outflow of things that enables you to live comfortably in that space. Messy people almost always have too much stuff for their space and therefore not enough places to put things. (This is true no matter how large or small your home is, sorry to say.) Neat people keep things pared down so that everything can have its own place. Regular purging of excess stuff and not holding onto things "just in case" is a huge key to staying neat and tidy.

I can't say that I perfectly implement all of these things all the time, but I can say that being aware of these mindsets and habits and attempting to live more like my "neat freak" loved ones has made a big difference in my home and how I feel about living in it.

Woman's rare antique turned away from 'Antique Roadshow' for beautiful heart-wrenching reason

"I just love you for bringing it in and thank you so much for making me so sad."

Woman's antique turned away from 'Antique Roadshow'

People come by things in all sorts of ways. Sometimes you find something while at a garage sale and sometimes it's because a family member passed away and it was left to them. After coming into possession of the item, the owner may be tempted to see how much it's worth so it can be documented for insurance purposes or sold.

On a recent episode of BBC One's Antique Roadshow, a woman brought an ivory bracelet to be appraised. Interestingly enough, the expert didn't meet this rare find with excitement, but appeared somber. The antique expert, Ronnie Archer-Morgan carefully explains the purpose of the bracelet in what appears to be a tense emotional exchange.

There would be no appraisal of this antique ivory bracelet adorned with beautiful script around the circumference. Archer-Morgan gives a brief disclaimer that he and the Antique Roadshow disapprove of the trade of ivory, though that was not his reason for refusing the ivory bangle.

"This ivory bangle here is not about trading in ivory, it’s about trading in human life, and it’s probably one of the most difficult things that I’ve ever had to talk about. But talk about it we must," Archer-Morgan says.

Turns out the woman had no idea what she had in her possession as she purchased it from an estate sale over 30 years before. One of the elderly residents she cared for passed away and the woman found the ivory bracelet among the things being sold. Finding the bangle particularly intriguing with the fancy inscription around it, she decided to purchase the unique piece of jewelry.

After explaining that his great-grandmother was once enslaved in Nova Scotia, Canada before being returned to Sierra Leone, Archer-Morgan concluded he could not price the item.

"I just don’t want to value it. I do not want to put a price on something that signifies such an awful business. But the value is in the lessons that this can tell people," he tells the woman.

In the end the woman leaves without knowing the monetary value of the item but with a wealth of knowledge she didn't have before visiting. Now she can continue to share the significance of the antique with others. Watch the full explanation below.

Benedict Cumberbatch reads Kurt Vonnegut's ultra-timely letter to people living in 2088

Cumberbatch's delivery and Vonnegut's words are a match made in literary heaven.

Kurt Vonnegut by Bernard Gotfryd (1965)/Wikipedia, UKinUSA/Wikipedia

Kurt Vonnegut (left), Benedict Cumberbatch right)

Back in 1988, writer Kurt Vonnegut was tasked with writing a letter to the planetary citizens of Earth in 2088 as part of Volkswagen’s TIME magazine ad campaign. And that he did, using his signature blend of dark humor, simple, conversational tone, and a poignant, enduring wisdom that’s almost medicinal—difficult to swallow, but oh so necessary.

In the letter, after quoting Shakespeare, St. John the Divine, and the well known Serenity prayer used in Alcoholic Anonymous groups, Vonnegut then dived into more somber matters—how “violent and heartless nature can be.” He argued that “Nature was no conservationist. It needed no help from us in taking the planet apart and putting it back together some different way, not necessarily improving it from the viewpoint of living things.” Therefore, it is ultimately humanity’s responsibility to ensure our well being remains preserved.

To work with “Nature’s stern but reasonable surrender terms,” Vonnegut advised the following:

1. Reduce and stabilize your population.

2. Stop poisoning the air, the water, and the topsoil.

3. Stop preparing for war and start dealing with your real problems.

4. Teach your kids, and yourselves, too, while you’re at it, how to inhabit a small planet without helping to kill it.

5. Stop thinking science can fix anything if you give it a trillion dollars.

6. Stop thinking your grandchildren will be OK no matter how wasteful or destructive you may be, since they can go to a nice new planet on a spaceship. That is really mean, and stupid.

7. And so on. Or else.

Vonnegut concluded with an eerily accurate depiction not of life 2088, but as we are experiencing it now. “Nobody will have to leave home to go to work or school, or even stop watching television. Everybody will sit around all day punching the keys of computer terminals connected to everything there is.”

If these words feel impactful (not to mention utterly relevant) just reading them now, wait til you hear them delivered by actor Benedict Cumberbatch, who even went the extra mile using an American accent, below:

- YouTubewww.youtube.com

This video was part of the Letters Live series, which often has actors doing live staged reading of interesting, funny, or dramatic letters excavated from libraries, museums and other archives. Cumberbatch, one of the co-producers of Letters Live, is also a regular reader. But there’s about the combo between Vonnegut’s timeless words and Cumberbatch’s impeccable delivery that makes this one particularly special.

Down in the comments, viewers expressed similar sentiments.

“KV’s letter should be broadcast on every corporate media available. His truth holds. Thank you Benedict Cumberbatch for your flawless reading!”

“Kurt Vonnegut, always having the right of it. Benedict Cumberbatch, always reiterating the message perfectly.”

“Touche' very appropriate timing for this much needed reflection! My dear Mr. Cumberbatch, you are an eloquent speaker.”

“Well said, and well read.”

“Wow that completely blew my mind and totally relevant today more than ever!!!! CHEERS!”

“Ok, at the end that got frighteningly accurate.”

Vonnegut always had a gift for biting satire and sharp insight into the darker aspects of humanity. And clearly, considering we are living out so many of his predictions much earlier than 2088, his words bear repeating.

3-step 'old man test' may predict a lot about your lifespan

Can you do this without cheating?

dr.tommymartin/TikTko & tami1231/TikTok

The TikTokers are at it again. This time, they're standing on one foot and trying not to fall over while they put on their socks and shoes. It might seem silly (and it definitely looks silly), but this latest social media challenge could actually reveal a lot about your health. Affectionately dubbed the 'Old Man Test' (or something the 'Old Person Test'), fitness trainer Chris Hinshaw initially developed the idea all the way back in 2021 as a way to test a person's balance, coordination, and biological age. It's been going viral ever since.

What is the 'Old Man Test'? How to try it at home

You've probably heard of similar challenges and tests like the famous sit-stand or sit-rise test, where you're challenged to sit down on the ground and stand back up again without using your hands and arms. Doing so successfully requires good balance, strength, stability, coordination, and even heart-health — making it a good indicator of how long you might expect to live.

There's also the bar-hang test, which posits that if you can dead hang from a pull-up bar for about 30-60 seconds, you're in good shape when it comes to how well you might age.

The Old Man Test is a lot like those, but some might say it's even more challenging. It consists of three-steps, which makes it unique:

Step One: Standing barefoot on one leg, reach down and grab your sock off the floor, then slide it onto the raised foot

Step Two: Still balancing on one foot, reach down and grab your shoe from the floor, and slide it on over the sock

Step Three: Still balancing, tie the shoe completely before lowering your foot back to the floor.

Now, if that wasn't hard enough, repeat for the other leg!

You can search TikTok or any social media for #oldmantest and see dozens of videos over the years of people attempting the challenge. You'll see men, women, young, and old alike doing it with varying levels of success. I even saw one challenge where the whole family, from pre-teen to grandma, all attempted the test at the same time!

Passing the test means your balance, core strength, flexibility, and coordination are looking good. Failing? Well...

@dr.tommymartin

Can you do this? Who remembers the old man test?

Why balance says so much about your health

One of the key similarities between many of the viral "longevity tests" is how good your balance is. Good balance has been correlated with living a longer life again and again in scientific studies. Why is that always the common denominator, and why does it tell us so much about how long we might live?

First, there's the obvious. The older we get, the more likely we are to fall, and the more likely those falls are to seriously hurt us. Having great coordination and balance keeps us safe from those accidental spills.

But the importance of balance goes deeper. It's such a foundational component of our health because it helps us maintain good posture as we get older, keeps our legs and cores strong, and can even help with our cognitive function.

If you have trouble with the sit-rise test or the Old Man Test, don't worry — balance is something that can be trained and improved.

Regular exercise and mobility work can help, as can balance-specific training like working with balance balls or doing one-legged exercises. Even long walks have been shown to improve balance. It could also be related to an issue with vision, the inner ear, or brain function — which, again, is why testing your balance and coordination is such an excellent indicator of overall health.

Also, don't take any viral fitness challenge as gospel. Some people are naturally less mobile and flexible than others due to limitations in their joints and muscles, and their inability to complete these tests may have nothing to do at all with fitness levels or overall health. So no, you aren't doomed to die young if you can't tie your shoe while balancing on one foot.

That doesn't mean it's not fun to give it a try!
