People share useless facts that simply won't leave their heads

Some facts are only useful for trivia contests.

Ah, useless facts. Random knowledge that serves no purpose other than to take up space in our brains, and maybe, just maybe, win a trivia game (yeah right) or kill time at a party.

Leave it to Ask Reddit to resurface all things odd and amusing, though. People shared their own useless facts that live rent free in their heads. And though they might be pointless, they are certainly entertaining.

Without further do:

  Mitochondria is the powerhouse of the cell.

Yep, this useless fact has stayed with us since elementary school. On the bright side, it’s been the source of many a fun meme.

Vending machines are more deadly than sharks.

Think about this next time you go to retrieve a Snickers bar: Between 2002 and 2015, the National Electronic Surveillance System reported that vending machines caused four deaths per year in the U.S. Mostly due to people tipping the machines onto themselves.

Compare that to the shark-related deaths averaging out to just 0.6 deaths per year. Not sure how only about half of a person is considered dead, but math was never my strength.

This statistic might need to be taken with a grain of sea salt, however, given that those in landlocked states have next-to-zero chances of experiencing a shark attack. But there you have it, a useless fact to use when you’re at the beach.

Snails have teeth.

“They’re not big enough teeth to hurt humans. That’s what makes it a useless fact to know. & it won’t leave my head because it’s juuuuuust disturbing enough to make me rethink my entire opinion on snails.” – ghosts-go-boo

But cows do not.

At least, no upper front teeth. Makes chewing—and dentist visits—easier I suppose.

The Sun is about 400 times bigger than the Moon but also about 400 times farther away from Earth. So they look to be about the same size.

Pigeons and doves are in the same bird family.

Columbidae is a subspecies of birds that are stout bodied, with short necks, and primarily feed on seeds, fruits and plants. Though one lives on as a symbol of peace and love, and the other is often considered a flying rat, the names are practically interchangeable.

However, thinking about Stevie Nicks singing, “just like a white-winged pigeon” doesn’t have quite the same ring to it.

The length of a jiffy…

According to ScienceFocus.com, physicists use a “jiffy” to define how long light takes to travel one femtometer (which is a tiny fraction of a millimeter). In layman’s terms, one jiffy equals one-fiftieth of a second.

So next time you say, “be back in a jiffy,” know that you better return really, really, really fast.

Most corn is inedible for humans.

“1% of the corn grown in the USA is sweet corn (the corn you eat as corn). The other 99% is field corn (or dent corn), which is fairly inedible raw and needs to be processed before human consumption. This field corn is also what they use for non-edible corn products, like ethanol, paint, cosmetics, etc. Yes, most corn goes to livestock feed. Ethanol and High Fructose Corn Syrup are up there as well. Yes, if you're driving on a highway and are passing fields of corn, you very likely cannot eat it.” – Kat_lbltko1pl

Infants have flexible bones.

Ever wonder why toddlers seem so much more flexible? This is because a baby’s skeleton is very different from an adult's. Babies are born with about 300 bones (94 more than adults) that are joined together with pliable cartilage to make that whole birth thing possible. As they get older, the bones will fuse together. And suddenly that toe touch is nothing but a distant dream of the past.

Numbers from 1-999 don't have the letter "a" in word form.

Some vowels just don’t get the respect they deserve.

John Wilkes Booth and Lee Harvey Oswald are both known by three names. And each full name is composed of 15 letters.

Actually, this is not entirely correct. Oswald’s full name was not used until after Kennedy’s assassination, due to his habit of adopting false names.

Cockroaches molt.

Unlike a reptile shedding it’s skin, cockroaches molt out of their entire exoskeleton. Out crawls a soft, fleshy, ghostly-white creature that will turn brown over a few hours. You’re welcome for the nightmare fuel.

There you have it. Gems of wisdom no one asked for. They say knowledge is power. But in this case, I’d say knowledge is unnecessary. But still fun!

Optometrists warn people against waterproof mascara due to the risk of unsightly eye damage

It can enter the tear film and get absorbed into the eyelid.

Waterproof mascara is causing eye damage according to optometrists

Eyes are a very sensitive part of the body, they quickly remind people of that when a spec of dust dares to sneak beneath the eyelid. The near microscopic dust particle suddenly feels like a large piece of spiked gravel refusing to dislodge itself no matter how much our eye waters trying to release it. The same goes for pretty much anything that makes its way into your eye.

Your own eyelashes that are supposed to serve as sentries standing guard to keep things out of your eyes sometimes betray you by falling directly into them. Just about anything can cause eye irritation and makeup is no different, especially if you rub your eyes while wearing it. But optometrists are warning against one particular type of eye makeup–waterproof mascara.

Yes, one of the greatest makeup inventions to come out of the twentieth century. Though the first version of waterproof mascara made in 1938 contained turpentine which of course resulted in unpleasant reactions, it was perfected in the 60s. No more worries about looking like a raccoon if you're caught in the rain or worse, have your feelings hurt and begin to cry. The popularity of the cosmetic exploded once the toxic ingredient was removed, yet eye doctors are saying to stay away. Why?

Several optometrists have taken to social media and YouTube over the years to discuss the risk of wearing waterproof mascara and eyeliner.

Dr. Gurleen Dhanoa explains, "it's right there in the name, waterproof mascara. Waterproof meaning it will not breakdown when in contact with water and our tear film is mostly comprised of water," she says before continuing to answer a commenter's question. "So when waterproof makeup enters the eye and tear film, which is inevitable, makeup is going to get into the eye, it doesn't breakdown and then it has nowhere to go but into the structures."

Once the waterproof makeup enters the structures of the eye it can cause a lot of damage, inflammation and irritation. This can cause people a lot of frustration because they may constantly feel like something is in their eyes which means more rubbing of the eyes leading to more irritation.

Ophthalmologist, Dr. Rupa Wong says, "if you do use waterproof makeup just remember to remove it thoroughly, it does take a little bit more work than regular eye makeup but you want to remove your eye makeup every single night. Don't be lazy, this is important because otherwise you can be prone to infections, inflammation, lash mites, none of the stuff that you want."


Several eye doctors have cited studies and their own experience seeing patients experiencing eye irritation as the result of waterproof mascara getting into the tear film of the eye. One doctor shares that his patient hadn't worn mascara in over ten years yet when he looked under her eyelid, the small black specs from that previously worn mascara were speckled throughout her eye's tear film. But how on earth do you get the mascara out of the tear film once its embedded?

Monica M. Dweck, MD, an ophthalmologist at the New York Eye and Ear Infirmary of Mount Sinai tells Ophthalmology Advisor, that improper removal of eye makeup and sleeping in eye makeup can clog the meibomian glands which can lead to meibomian gland dysfunction to which there is no cure. “It can be managed, and it can be controlled, but there’s no cure.”


@doctoreyehealth Did you know!? —> Mascara and other eye makeup products can sometimes get trapped under the eyelid and be absorbed into the eyelid tissue. It’s essential to be cautious when applying eye makeup and to remove it thoroughly using gentle makeup removers specifically designed for the eyes. Additionally, practicing good eye hygiene and avoiding excessive rubbing or touching of the eyes can help reduce the risk of makeup particles getting trapped under the eyelid and absorbed into the eyelid tissue. If you ever experience discomfort or notice makeup residue accumulating under your eyelid, it’s a good idea to consult with an eye care professional for guidance and proper care.

The meibomian glands help produce the oil needed to make tears which are constantly produced by your eyes to keep them from drying out. But when speaking to the Ophthalmology Advisor, Dr. Di Meglio reports that they can die out when makeup is consistently applied to the waterline. "If those glands die out, they can be gone forever… If you’re putting eyeliner along there, you’re giving yourself a little bit more of a chance of having gland dysfunction. If the oil stays stagnant…the glands themselves can atrophy.”

Waterproof mascaras and other eye makeup may be fantastic inventions to help keep things from running down your cheeks on humid or rainy days but the risk of wearing it daily may be too much for some people. Whether you should wear it or not is split amongst the different eye doctors with some saying don't wear it at all and others saying occasional use is fine as long as you remove it properly and avoid ever sleeping in it. It's up to each individual person to decide if they're willing to take the risk.

New research says cold plunges are overrated. Long live hot baths.

If it ain't broke, don't fix it.

It's safe to say that cold plunges, or several-minute-long ice baths, are having a moment. Athletes have been using them forever to recover from workouts and rigorous games (the ancient Greeks even liked it!), but at some point in recent years, cold plunging entered the zeitgeist as an everyday therapy for normal people.

Celebrities like Drake and Justin Bieber can be seen submerging themselves in frigid water on social media. Joe Rogan relentlessly evangelizes the benefits of cold plunging to his listeners. Fitness influencers all over the globe are pushing cold plunging as the key to unlocking better results.

What are the benefits of cold plunging? For starters, it reduces inflammation in muscles, which reduces soreness. It also makes you feel absolutely amazing, as the shock of the cold water causes an intense rush of adrenaline and dopamine in the body, creating a sort of natural high that can last for hours. Some experts claim that cold plunges can reduce anxiety and stress, boost metabolism, and even keep you from getting sick!

All that with very little drawbacks, the main one being that hopping neck-deep into 50 degree water is intensely uncomfortable.

New research out of Ritsumeikan University in Japan is throwing some cold water on the trend. According to the study, a good old fashioned hot bath is a better choice for more people. And more fun, too.

Researchers took a group of 10 men and had them perform high-intensity exercise. Afterwards, one group soaked in a cold tub, one in a hot tub, and one just sat in a normal room as a control.

Not long after their 20-minute soak, the men performed high jumps, and the researchers measured how high they were able to jump.

The three-part study put the men through the rotation several times, so each man had eventually tried the cold tub, hot tub, and control room.

The findings showed that the men who soaked in the hot tub performed the best in the athletic testing afterwards.

Turns out, there's a downside to constricting the blood flow to your muscles and reducing inflammation and soreness. You also block the delivery of key nutrients and rich, oxygenated blood that promotes recovery.

Mamoru Tsuyuki, a master’s student in sports and health science and author of the study, reasoned that cold plunges still have their place when someone's injured or dealing with tremendous soreness. You can see why a Major League pitcher might dunk his arm in ice immediately after a game.

But most normal people don't need to hop into an ice bath after a workout. A hot soak is a lot more comfortable and will probably do a better job of helping those muscles recover quickly. Warmth and better bloodflow will also prioritize building new muscles rather than minimizing soreness.

(It's also worth mentioning that, unlike a hot bath, cold plunging can be pretty dangerous. If the water is too cold, you risk going into shock or hypothermia.)

Overall, the scientific community is skeptical at best of the supposed amazing benefits to cold plunging. So why did it get so popular?

The fitness community has a new cold plunge every few years.

For a while, we were sure that High-Intensity Interval Training was THE answer to all your exercise woes. Then it was foam rollers that were going to unlock all of your flexibility and mobility and send your soreness packing. Same with cupping. Then it was the massage gun, the ultimate workout recovery tool. And on and on with Peloton and Bowflex and those vibrating As Seen on TV ab belts.

The truth we don't want to admit is that everybody's body is different, and what works well for one person may not work for us. That's because it's not an easy idea to sell, it's not profitable. No one wants to buy a $5,000 cold plunge set up unless they're convinced it's going to change their life.

So influencers play up the benefits. It's what they do.

Some people love cold plunging, and they have every right to enjoy it! Others find it miserable, and that's OK, too. Cold plunging has legitimate scientific benefits, but it also has drawbacks, dangers, and a whole lot of pseudo-science behind it. It's absolutely OK if you'd rather take a warm bath or soak in the hot tub after a workout.

Now you have scientific evidence in your corner next time someone tries to pressure you into an ice bath. Just say, "Nah, I'm prioritizing bloodflow and muscle recovery today. But you have fun."

Here’s how one nonprofit org is using Adobe to change the world

Adobe empowers nonprofits to fundraise, advocate, and further their missions.

True

In 2024, it’s practically impossible to function as a nonprofit without the right digital resources. Nonprofits use computer systems and applications for things like education, fundraising, engaging clients, and communicating with donors. However, with limited funding and expertise, it's often difficult to get the digital tools they need to fully support their missions.

The planet needs nonprofit organizations, and nonprofits need better digital tools. For decades, Adobe has provided nonprofits with the tools they need to fulfill their mission—helping them with everything from social media advocacy to educational videos to graphic design. Now, Adobe is offering the pro version of Adobe Acrobat for Nonprofits, the most requested and comprehensive set of document and e-signature tools, for just $15 per user per year, which represents a 94% annual savings off the regular price. This will make it easier than ever for nonprofits to streamline business processes and increase their impact with engaging educational and fundraising assets – from annual reports, contracts and grant submissions to brochures and white papers.

Keep reading to hear more about how Adobe helped one nonprofit improve efficiencies and giveback potential – and how you can start using Adobe tools today for your organization.

A nonprofit success story

Albert Manero, a mechanical engineer and graduate of the University of Central Florida, founded Limbitless Solutions, Inc., as a passion project in a small lab. Today, Limbitless is celebrating its 10-year anniversary and has grown into an interdisciplinary team based at the University of Central Florida in Orlando that includes 50 interns with nine different fields of expertise. Their mission? To inspire and empower underserved communities through creative, accessible technology.

Manero and his team of experts create bionic, 3D-printed arms for children with limb differences. Combining visual storytelling with art and engineering, the Limbitless team wants children with limb differences to feel included and capable, while at the same time, able to express their personal identity more fully. Developing bionic arms covered in flowers or designed like Iron Man’s armor, kids with these bionic limbs can not only grip objects, hold hands and more, but can feel empowered to be themselves.

Using Adobe to make a difference

Limbitless, like many others, has utilized Adobe for Nonprofits offerings, which gives nonprofit organizations access to Adobe programs at a deeply discounted rate, including access programs like Adobe Illustrator, Adobe Express and Adobe Acrobat as well as Adobe’s 3D tools.

Adobe solutions are the oil that keeps organizations running smoothly behind the scenes. For the grant application and reporting processes, employees at Limbitless have credited Adobe Acrobat with helping the team secure funding and communicating clearly with donors and partners. With Acrobat, they’re able to create, edit, and manage PDF documents that look professional and polished. The company has also transitioned most of its internal documentation to digital formats using Acrobat. This includes everything from design blueprints, brand guidelines, intern contracts, and user manuals for bionic limbs.

Better tech for a better future

In addition to helping day-to-day operations run smoothly, Adobe has also helped bring Limbitless’ mission of inclusion and accessibility outside of office walls.

Using Adobe Express, the fast and easy create-anything app, Limbitless has been able to create quick how-to videos for young patients and their families that showcase how to use their bionic limbs, as well as a series of videos promoting STEAM (science, technology, engineering art and math) education. The company’s Operations, Advocacy, and Logistics team utilizes Express as well, developing content and visual assets for their social media accounts. Recently, Limbitless partnered with the Adobe Express’ Animate Characters team to create six unique, limb-different selectable avatar characters for their educational outreach and social media campaigns.

And Adobe is helping Limbitless empower kids with limb differences, too: Limbitless’ comic series, Bionic Kid, was created using Adobe Illustrator and features a superhero with limb differences who uses a Limbitless prosthetic arm. This inspired a fundraising concept initiated from the idea by a Limbitless prosthetic recipient Zachary Pamboukas, which has been used in fundraising efforts for more bionic arms and has already raised over $20,000.

Inside the organization and out, Adobe is enabling people to reach their full potential, contributing to better nonprofit organizations and, overall, a better world.
