11 Insane Features of Normal Human Anatomy

Sure, we’ve wowed you with medical oddities, but why should abnormal bodies get all the attention? The truth about the normal human body can be stranger than fiction. To prove it, here are 11 weird facts about the body you thought you knew.

1. Your Tongue

What does your tongue have in common with an octopus’ tentacle and an elephant’s trunk? All three are examples of a unique structure called the “muscular hydrostat,” a bundle of muscles that work without the assistance of bones. Like anything made mostly of water, the hydrostat has a constant volume, so when certain cells contract, the whole thing has to expand somewhere else. The result is a body part that is both strong and flexible. If your tongue were as big as an elephant’s trunk, it could uproot trees too.

2. Your Hyoid Bone

This wee, horseshoe-shaped bone will never appear in the song by James Weldon Johnson, as it’s connected to...no bones at all, in a meaningful sense; its job is independent of the rest of the skeleton. Also known as the lingual bone, the hyoid bone sits atop the larynx, providing an anchor for the muscles on the floor of the mouth, the tongue. Don’t worry: you’re not likely to break this bone, unless someone starts choking you to death. At that point, you’ve got bigger problems.

3. Your Philtrum

No, that little indent under your nose isn’t there to make it difficult to apply lipstick in the dark, but it doesn’t serve any other purpose either. The indent, called the philtrum, is just a residual reminder of your time in the womb: in utero, the two sides of your face develop independent of one another, then join at the middle. When the two sides fail to fuse properly, the result is a cleft palate, which occurs in about 1 of every 750 births. Ancient Romans found the philtrum erotic, and named that lipstick-thwarting dip in the upper lip “Cupid’s Bow.” In fact, the word philtrum comes from a Greek term meaning “love potion.”

4. Your Hair

People love tossing around hair facts. That old wives tale about it growing after you’re dead? A fun fallacy. After you die, your hair and nails don’t continue growing, but the skin retreats as it dehydrates, causing that creepy illusion of ghoulish growth.

In truth, hair is a weird combination of living and dead. The living hair follicle pushes out the hair, which is made up of different kinds of non-living yet protective cells made of keratin — the same keratin that's on your top (dead) layer of skin, and in your nails. When your hair turns grey, it means your pigment cells are dying. Yet another hairy reminder of your own mortality.

5. Your Nails

Ever notice how your toenails grow more slowly than your fingernails? That’s because there’s an evolutionary correlation between the length of your “terminal phalanges” (the outer-most bones in your toes and finger-tips) and the rate at which your nails grow. The tips of your toes are shorter than your fingertips, so your toenails don't grow as fast. In the same way, the nail on your middle finger will grow faster than the nail on your pinky. The seemingly random correlation has to do with the lessening necessity of claws through human evolution. If your fingernails are thick and grow quickly, ask yourself the question: “Should I be digging more?”

6. Your Bioluminescence

Fireflies and jellyfish glow, but humans? Believe it. The phenomenon is a natural byproduct of the metabolic process, and scientists have long been aware of the presence of bioluminescence in most living creatures. But it wasn’t until 2009, when a team of Japanese researchers developed a camera 1000 times more sensitive than the human eye, that human bioluminescence was captured on film. The light show apparently works on a 24-hour cycle — brightest in the late afternoon and on the cheeks, forehead and neck. Next time someone tells you “you’re glowing,” you can take it literally.

7. Your Walking Proteins

Of the microscopic menagerie that is your cell biology, the most bizarre member is perhaps the kinesin protein, a “motor” protein whose job it is to deliver important molecules to their necessary cellular destinations. What’s most remarkable is the kinesin’s mode of transportation: It “walks” along its micro-pathway using two structures at its base commonly referred to as “feet.” Though scientists disagree as to exactly how these feet were “made for walking,” there’s no denying that the mode of transportation closely resembles that of the humans they assist.

8. Your Sonic Hedgehog

What’s more complex than cell biology? Cell biology in your infinitely complex brain. In 1993, scientists discovered a protein in the hippocampus instrumental in developing a variety of neural traits. Isolated in fruit flies, the protein causes spines to grow on the back, so the scientists named it “Sonic” after the spiny Sega Genesis character. Similar proteins are named desert hedgehog and Indian hedgehog. Who says scientists don’t have fun?

9. Your Liver

The lumpy, lobey, unwieldy liver gets a bad rap, but if you didn’t have it in there cleaning out your system, you’d be looking pretty bad yourself. Lucky for you, the liver is perhaps the most resilient of the major organs: it can regenerate from only 25% of its tissue mass. You wouldn’t vote it the cutest kid in school, but “Most Likely to Succeed”? Maybe.

10. Your Vomeronasal Organ

There are important organs, and there are ones just along for the ride. As far as useless leftover body parts, you’ve probably heard about the tailbone, the appendix, even the little toe (wee wee wee all the way home). But you may not have heard of the “vomeronasal organ,” located unglamorously inside the nose.

Back in the day, the little guy used to aid in detecting subtle airborne information, most importantly, pheromones from a member of the opposite sex. In the age of modern man, the vomeronasal organ doesn’t appear to be doing much -- it doesn’t even have nerves connecting it to the brain. Still, scientists continue to argue about the potential chemical messages it might be sending, titillating that part of us that is still animal.

11. Your Sexy Bits

And speaking of pheromones and vestigial organs...

Men and women have more in common “down there” than you might think. Because the sex organs of a fetus don’t develop until about five months into development, males and females have remnants of the opposite sexual organs — and some are more useful than others. While the penis is basically an enlarged version of a lady’s clitoris, the male remnant of the lower vagina is less useful. Called the prostatic utricle (Latin for “pouch of the prostate”), the little-discussed fleshy sac just kind of hangs out near the prostate gland, leading nowhere. In the 1800s, the structure was more commonly called the vagina masculina, which requires no translation.

11 Ridiculously Overdue Library Books (That Were Finally Returned)
Original image

Last week, Massachusetts's Attleboro Public Library received a big surprise when one of its regular patrons returned a copy of T.S. Arthur's The Young Lady at Home ... more than 78 years after it had been checked out. 

The man, whose name was not revealed, was reportedly helping a friend clean out his basement when he came across the tome. He recognized the library's stamp, then noticed its original due date: November 21, 1938. “We were amazed,” said Amy Rhilinger, the library’s assistant director. “I’ve worked here for 15 years, and I’ve never seen anything like this before.”

Because the library charges $.10 per day for overdue books, the total bill for this dusty read would come to about $2800—but the library isn't planning to cash in. “We’re not the library police," Rhilinger said. "We’re not tracking everyone’s things. Everyone returns things a few [days] late, and it’s one thing we joke about here.”

Though it's rare, the decades-overdue book's return is not unprecedented. Here are 11 more tardy returns.

1. The Versatile Grain and the Elegant Bean: A Celebration of the World’s Most Healthful Foods by Sheryl and Mel London

LOANED FROM: The Lawrence Public Library in Lawrence, Kansas
YEARS OVERDUE: 21

In 2014, someone anonymously returned this fitness-friendly cookbook, which had been missing since September 24, 1992. The volume, published that April, contains over 300 recipes—and it’s probably safe to assume that the culprit had plenty of time to try out every single one of them.

2. The Real Book About Snakes by Jane Sherman

LOANED FROM: The Champaign County Library in Urbana, Ohio 
YEARS OVERDUE: 41

Like the previous entry, whoever turned in this musty old field guide declined to reveal his name. But lest anyone question the man’s honesty, he also left the following note: “Sorry I’ve kept this book so long, but I’m a really slow reader! I’ve enclosed my fine of $299.30 (41 years, 2 cents a day). Once again, my apologies!”

3. Days and Deeds: A Book of Verse for Children’s Reading and Speaking compiled by Burton and Elizabeth Stevenson

LOANED FROM: The Kewanee Public Library in Kewanee, Illinois
YEARS OVERDUE: 47

According to Guinness World Records, the $345.14 fee paid by the borrower of this lyrical compilation stands as the highest library fine ever paid.

4. The Fire of Francis Xavier by Arthur R. McGratty

LOANED FROM: The New York Public Library, Fort Washington Branch, in New York, New York
YEARS OVERDUE: 55

In 2013, this one was discreetly mailed in and the perpetrator was never brought to justice (be on guard, Big Apple bibliophiles).

5. The Adventures of Pinocchio by Carlo Collodi

LOANED FROM: The Rugby Library in Warwick, England 
YEARS OVERDUE: 63

The item found its way home during an eight-day “fines amnesty period,” which shielded the guilty patron from a £4000 penalty. “It’s amazing to think how much the library has changed since that book was taken out in 1950,” said librarian Joanna Girdle. 

6. The Picture of Dorian Gray by Oscar Wilde

LOANED FROM: The Chicago Public Library in Chicago, Illinois 
YEARS OVERDUE: 78

Harlean Hoffman Vision found a rare edition of this novel nestled amongst her late mother’s personal effects and vowed to set things right. “She kept saying, ‘You’re not going to arrest me?’” recalled marketing director Ruth Lednicer, “and we said, ‘No, we’re so happy you brought it back.’”

7. Master of Men by E. Phillips Oppenheim

Amazon, Public Domain

LOANED FROM: The Leicester County Library in Leicester, England
YEARS OVERDUE: 79

Oppenheim was born in the surrounding region and, hence, the Leicestershire County Council was thrilled to reclaim this piece of their literary heritage after it turned up in a nearby house—even though the library branch it originally belonged to had shut down decades earlier.

8. Facts I Ought to Know About the Government of My Country by William H. Bartlett

Amazon, Public Domain

LOANED FROM: The New Bedford Public Library in New Bedford, Massachusetts
YEARS OVERDUE: 99

Stanley Dudek of Mansfield, Massachusetts claims that his mother—a Polish immigrant—decided to brush up on American politics by borrowing this volume from the New Bedford Library in 1910. “For a person who was just becoming a citizen, it was the perfect book for her,” says Dudek.

9. Insectivorous Plants by Charles Darwin

LOANED FROM: The Camden School of Arts Lending Library in Sydney, Australia
YEARS OVERDUE: 122

An Australian copy of Darwin’s treatise on bug-eating flora was borrowed in 1889. After two World Wars, Neil Armstrong’s moon landing, and the birth of the internet, it was finally returned on July 22, 2011.

10. The Ancient History of the Egyptians, Carthaginians, Assyrians, Babylonians, Medes and Persians, Macedonians, and Grecians (volume II) by Charles Rollin

LOANED FROM: The Grace Doherty Library in Danville, Kentucky
YEARS OVERDUE: 150 (approximately)

In 2013, this tome was discovered at a neighboring school for the deaf, where it had presumably been stored since 1854 (as evidenced by a note written inside dating to that year). The library owns no records from this period, so exactly how long it was gone is anybody’s guess, but, said librarian Stan Campbell, “It’s been out of the library for at least 150 years."

11. The Law of Nations by Emmerich de Vattel

LOANED FROM: The New York Society Library in New York City
YEARS OVERDUE: 221

Five months into his first presidential term, George Washington borrowed this legal manifesto from the historic New York Society Library. For the next 221 years, it remained stowed away at his Virginia home, and organization officials wondered if they’d ever see it again. “We’re not actively pursuing overdue fines,” joked head librarian Mark Bartlett. “But we would be very happy to see the book returned.” His wish was granted when Mount Vernon staff finally sent it back in 2010 (luckily, they dodged a whopping $300,000 late fee).

11 Popular Quotes Commonly Misattributed to F. Scott Fitzgerald
Original image
Hulton Archive/Getty Images

F. Scott Fitzgerald wrote a lot of famous lines, from musings on failure in Tender is the Night to “so we beat on, boats against the current” from The Great Gatsby. Yet even with a seemingly never-ending well of words and beautiful quotations, many popular idioms and phrases are wrongly attributed to the famous Jazz Age author, who was born on this day in 1896. Here are 11 popular phrases that are often misattributed to Fitzgerald. (You may need to update your Pinterest boards.)

1. “WRITE DRUNK, EDIT SOBER.”

This quote is often attributed to either Fitzgerald or his contemporary, Ernest Hemingway, who died in 1961. There is no evidence in the collected works of either writer to support that attribution; the idea was first associated with Fitzgerald in a 1996 Associated Press story, and later in Stephen Fry’s memoir More Fool Me. In actuality, humorist Peter De Vries coined an early version of the phrase in a 1964 novel titled Reuben, Reuben.

2. “FOR WHAT IT’S WORTH: IT’S NEVER TOO LATE OR, IN MY CASE, TOO EARLY TO BE WHOEVER YOU WANT TO BE.”

It’s easy to see where the mistake could be made regarding this quote: Fitzgerald wrote the short story “The Curious Case of Benjamin Button” in 1922 for Collier's Magazine, and it was adapted into a movie of the same name, directed by David Fincher and starring Brad Pitt and Cate Blanchett, in 2008. Eric Roth wrote the screenplay, in which that quotation appears.

3. “OUR LIVES ARE DEFINED BY OPPORTUNITIES, EVEN THE ONES WE MISS.”

This is a similar case to the previous quotation; this quote is attributed to Benjamin Button’s character in the film adaptation. It’s found in the script, but not in the original short story.

4. “YOU’LL UNDERSTAND WHY STORMS ARE NAMED AFTER PEOPLE.”

There is no evidence that Fitzgerald penned this line in any of his known works. In this Pinterest pin, it is attributed to his novel The Beautiful and Damned. However, nothing like that appears in the book; additionally, according to the National Atmospheric and Oceanic Association, although there were a few storms named after saints, and an Australian meteorologist was giving storms names in the 19th century, the practice didn’t become widespread until after 1941. Fitzgerald died in 1940.

5. “A SENTIMENTAL PERSON THINKS THINGS WILL LAST. A ROMANTIC PERSON HAS A DESPERATE CONFIDENCE THAT THEY WON’T.”

This exact quote does not appear in Fitzgerald’s work—though a version of it does, in his 1920 novel This Side of Paradise:

“No, I’m romantic—a sentimental person thinks things will last—a romantic person hopes against hope that they won’t. Sentiment is emotional.” The incorrect version is widely circulated and requoted.

6. “IT’S A FUNNY THING ABOUT COMING HOME. NOTHING CHANGES. EVERYTHING LOOKS THE SAME, FEELS THE SAME, EVEN SMELLS THE SAME. YOU REALIZE WHAT’S CHANGED IS YOU.”

This quote also appears in the 2008 The Curious Case of Benjamin Button script, but not in the original short story.

7. “GREAT BOOKS WRITE THEMSELVES; ONLY BAD BOOKS HAVE TO BE WRITTEN.”

There is no evidence of this quote in any of Fitzgerald’s writings; it mostly seems to circulate on websites like qotd.org, quotefancy.com and azquotes.com with no clarification as to where it originated.

8. “SHE WAS BEAUTIFUL, BUT NOT LIKE THOSE GIRLS IN THE MAGAZINES. SHE WAS BEAUTIFUL FOR THE WAY SHE THOUGHT. SHE WAS BEAUTIFUL FOR THE SPARKLE IN HER EYES WHEN SHE TALKED ABOUT SOMETHING SHE LOVED. SHE WAS BEAUTIFUL FOR HER ABILITY TO MAKE OTHER PEOPLE SMILE, EVEN IF SHE WAS SAD. NO, SHE WASN’T BEAUTIFUL FOR SOMETHING AS TEMPORARY AS HER LOOKS. SHE WAS BEAUTIFUL, DEEP DOWN TO HER SOUL.”

This quote may have originated in a memoir/advice book published in 2011 by Natalie Newman titled Butterflies and Bullshit, where it appears in its entirety. It was attributed to Fitzgerald in a January 2015 Thought Catalog article, and was quoted as written by an unknown source in Hello, Beauty Full: Seeing Yourself as God Sees You by Elisa Morgan, published in September 2015. However, there’s no evidence that Fitzgerald said or wrote anything like it.

9. “AND IN THE END, WE WERE ALL JUST HUMANS, DRUNK ON THE IDEA THAT LOVE, ONLY LOVE, COULD HEAL OUR BROKENNESS.”

Christopher Poindexter, the successful Instagram poet, wrote this as part of a cycle of poems called “the blooming of madness” in 2013. After a Twitter account called @SirJayGatsby tweeted the phrase with no attribution, it went viral as being attributed to Fitzgerald. Poindexter has addressed its origin on several occasions.

10. “YOU NEED CHAOS IN YOUR SOUL TO GIVE BIRTH TO A DANCING STAR.”

This poetic phrase is actually derived from the work of philosopher Friedrich Nietzsche, who died in 1900, just four years after Fitzgerald was born in 1896. In his book Thus Spake ZarathustraNietzsche wrote the phrase, “One must have chaos within to enable one to give birth to a dancing star.” Over time, it’s been truncated and modernized into the currently popular version, which was included in the 2009 book You Majored in What?: Designing Your Path from College to Career by Katharine Brooks.

11. “FOR THE GIRLS WITH MESSY HAIR AND THIRSTY HEARTS.”

This quote is the dedication in Jodi Lynn Anderson’s book Tiger Lily, a reimagining of the classic story of Peter Pan. While it is often attributed to Anderson, many Tumblr pages and online posts cite Fitzgerald as its author.
