Hidden quirks

Offbeat Anatomy: 15 body oddities you may not know about

With its labyrinthine systems and intricate mechanisms, the human body is full of surprises, hidden quirks, and mysteries. Take blushing, for example, did you know that only humans are capable of such a thing? And what about earwax? We all know our body produces it to prevent bacteria from getting in, but did you know it is a type of sweat?

Until now, you may have thought you had a good handle on your body, but you probably have a few things to learn about it. Read on to find out fifteen weird facts about the human body and its endless wonders.

Have you ever wondered why you're a tad taller in the morning? That’s right, it’s not just your imagination playing tricks on you! Just as our weight is not the same throughout the day, neither is our height.

That is because, during the night, when we sleep horizontally, the soft cartilage between our bones gets a chance to decompress. The temporary relief from gravity leads to a slight increase in height by morning. But enjoy it while you can because it’s all downhill from here!

As the day progresses and we stand upright and carry out our daily activities, gravity compresses our spine back, causing our discs to flatten, and ultimately leading to a minimum loss of height.

Our noses are not only adept at sniffing out scents but also possess an astonishing memory. To put it simply: our noses are just like a built-in scent database in the middle of our faces.

How does that work? The nose is armed with up to 400 scent receptors, which means that we can identify millions of different odors, from recently baked chocolate cookies to the stinky odor of sweaty gym socks!

Now, this is mind-blowing: the average human nose can distinguish and remember up to 50,000 different smells. On a less friendly note, it still hasn’t quite mastered the ability to forget about the unfortunate smells of life!

Did you know that the core of your spinal discs is primarily composed of water? That’s right, the little discs between our vertebrae are like sponges. The water makes them plumpy and healthy. This means that, as long as our body is properly hydrated, our discs will be able to absorb shock and protect our spine like a pro.

As a natural consequence, when we don’t drink enough water or keep hydrated, these discs start to feel the squeeze. With no water to plump them up, they lose their main function and our spine bones are prone to rub against each other. And that’s when the back pain comes rushing.

If there weren’t enough reasons already, here is just another one to keep up with your water intake.

It’s a known fact that our left and right sides are not exactly the same. And this rule also applies to our internal organs. So it doesn’t come as a surprise that the left lung is approximately ten percent smaller than the right lung.

This has quite a simple and logical explanation to it: for starters, our heart is not perfectly placed in the center of our chest. Considering it is slightly tilted to the left, the left lung is smaller in order to give the heart some space, making it smaller than the right.

Moreover, because the liver sits high on the right side of our body, the right lung is wider but a tad shorter than the left.

Crying is the first thing a baby does. The minute they are welcomed into the world, they put their lungs to work. But have you ever noticed they don’t shed any tears? As you can imagine, this is not because they are holding back, it is because they physically can’t!

Tear ducts, the ones responsible for this, are still developing in newborns like many other body parts. It is not until they have reached full maturity that babies will be able to let the tears fall, regardless of how loud they can get.

This process can take up to a month, and in some cases, even longer. So, if you see a crying baby with dry eyes, don’t worry! They are just waiting for the tear ducts to catch up!

The most elaborate cobweb has absolutely nothing on our circulatory system! The intricate network of blood vessels within the human body is truly astounding. Here’s a fact: at the absolute maximum, a large human body can contain up to 60,000 miles.

In case you can’t quite picture that, think of this: that’s enough to wrap around the Earth’s equator more than two times over! All of that complexity is neatly packed right inside us.

Think of all those blood vessels weaving their way through our body, carrying oxygen and nutrients to every last corner of it. It leaves you thinking, right?

Believe it or not, growth is not just reserved for childhood. While overall growth ceases in adulthood, certain body parts continue to exhibit growth throughout life. The nose and ears, for instance, have a mind of their own when it comes to this and they tend to grow larger with age.

Now, here is the trick about this oddity: it is not actual growth, it is all work of the relentless force of gravity!

Our ears and noses are mostly made of cartilage, which is highly flexible. As we age, even though it may seem as if they never cease growing, it is just gravity causing that cartilage to sag and stretch out making them look bigger.

Since earwax is highly considered disgusting by society, it is no surprise we know close to nothing about it. Contrary to popular belief, earwax is not simply a collection of dirt and debris and it is definitely not wax, that’s for sure!

Earwax is, in fact, a type of sweat. Our ear canal has two types of glands, the ceruminous and the sebaceous glands. The former is a sweat gland and it is the one responsible for producing this waxy substance. Therefore, the name.

Now, earwax, embarrassing as it may be, serves to lubricate and protect the delicate skin lining the ear canal, preventing dryness and irritation. So, rather than removing it, embrace it!

Just like fingerprints, each person's tongue boasts a unique and distinct pattern. So, there are no two fingerprints that are the same, and neither are two tongues.

These tongue prints, formed by a combination of papillae and taste buds, contribute to individuality and our identity. And get this, tongue prints are often used in forensic investigations for identification purposes.

And that is not all! As it turns out, color and shape are also unique features of each individual making the tongue a key tool for identification. And let’s not forget the rainbow of flavors we can taste thanks to it!

You may be quite skeptical about this, but human teeth are remarkable and stronger than you think!

Human teeth are incredibly durable, and their strength is comparable to that of shark teeth. Scientific studies show that when comparing the micro-structure of both, our teeth are no weaker than that of sharks. And it all comes down to one single element: enamel.

This discovery is attributed to the dense enamel covering the tooth's surface, which serves as a protective barrier against wear and tear.

Mind you, equally strong doesn’t mean equally sharp! You might not be able to slice through prey, but you will most certainly win the battle over a crispy apple.

We are all very much aware that blood has a vital role in maintaining our body at top performance. It is in charge of physiological balance and transporting essential nutrients and oxygen to tissues throughout the body.

One can also easily imagine that we have a fair amount of it circulating inside our bodies. But what you probably didn’t know is that it constitutes approximately eight percent of the average adult's body weight.

The number is not set in stone, depending on factors like age and size, this percentage can naturally vary. For example, blood takes up to ten percent of a baby’s body weight.

You may not notice it, but you typically only breathe through one nostril at a time. You have nothing to fear, this is completely normal and it is due to a congestion pattern that switches every couple of hours. During this cycle, one nostril becomes congested making it a bit harder for air to flow through it while the other becomes decongested.

This alternating pattern of nasal airflow, known as the nasal cycle, ensures optimal filtration, humidification, and warming of inhaled air, promoting efficient respiratory function. Noses are not just a scent database, they are also our air conditioning system.

Now that you read about it, you may be blinking on purpose, aren’t you? However, most of the time, blinking is an involuntary reflex of the cornea, that is, we don’t even notice we do it. Now, this is the quirky fact about it: blinking occurs around 20 times per minute, which actually equates to over ten million blinks per year!

This reflex is not just a habit, it is essential to keep our eyes healthy. Blinking serves to moisturize and protect the ocular surface, preventing dryness and debris accumulation.

Moreover, blinking is a defense mechanism. When things get too close to the eye, this instinctive action protects our eyes from potential damage.

Contrary to popular belief, the brain never clocks out, not even when we go to bed. It is quite the opposite, our brain is often more active during sleep than when we are awake. And this is key to our overall health and well-being!

During REM (rapid eye movement) sleep, the stage usually associated with vivid dreams and high cognitive function, the brain becomes notably active. It initiates the neural activity that triggers key cognitive processes such as memory consolidation and emotional regulation.

Unlike us, our brain never goes to sleep and we should thank it for feeling refreshed and ready to tackle the day ahead.

When we feel embarrassed or ashamed, our mind is not the only one at play, our bodies are quick to catch up with some significant transformations. We sweat, we move around in discomfort and we blush!

Blushing is the result of the dilation of the blood vessels and a physiological response to certain feelings. Now, what you probably didn’t know is that, despite its involuntary nature, humans are the only species known to do this.

This uniquely human response is triggered by emotions such as embarrassment, shame, or excitement, highlighting the intricate interplay between the mind and body. Remarkable, isn’t it?

Some names stick around

From Table Tap Joe to Ziggy Stardust: Who are the best song characters?

Sometimes, a character is the perfect alter-ego to write a song about oneself without self-referencing so much. Other times, a character is just a character. Over the years, musicians have come up with lonely dreamers, fearless heroes, mysterious strangers, and even supernatural villains who have become just as famous as the songs themselves. Some were inspired by real people, others sprang entirely from imagination, but all of them left a lasting mark on music history. Which of these 12 do you remember?

Tom Waits has always had a soft spot for society's oddballs, and few are even stranger than Table Top Joe. Introduced on the 2002 album Alice, Joe is born with only a head and hands, yet grows into a brilliant piano player whose extraordinary talent earns him fame despite the odds stacked against him.

The song unfolds like a forgotten American folk tale, complete with references to Coney Island's legendary Dreamland amusement park and composer Igor Stravinsky. Although many listeners assume the story is based on an old carnival legend, Table Top Joe is entirely Tom Waits' own creation.

Few fictional musicians have ever become as famous as Ziggy Stardust. Introduced in 1972, Ziggy is an alien rock star sent to Earth shortly before humanity's end, only to be consumed by the very fame that makes him a savior to millions.

David Bowie blurred the line between fiction and reality by performing as Ziggy onstage for more than a year. When he unexpectedly announced Ziggy's retirement during a concert at London's Hammersmith Odeon in 1973, many fans believed the character, and perhaps Bowie himself, had truly reached the end of the story.

Tommy Walker isn't just the hero of a song, he's the central figure of one of rock music's first great operas. After witnessing a traumatic event as a child, Tommy becomes deaf, mute, and blind, yet somehow develops astonishing pinball skills that transform him into an unlikely celebrity.

Pete Townshend built an entire musical world around Tommy, exploring themes of trauma, faith, and redemption. First released in 1969, Tommy later became a hit film, a Broadway production, and one of the most influential concept albums ever recorded.

Johnny B. Goode is every aspiring musician's dream. Growing up in rural Louisiana with little more than a guitar and natural talent, he plays so brilliantly that listeners predict "his name will be in lights."

Chuck Berry based the character partly on himself and partly on pianist Johnnie Johnson. Originally described as a "colored boy," Johnny became a "country boy" in the final lyrics, making the song more likely to receive airplay during the segregation era. Nearly two decades later, Johnny's anthem would even travel into space aboard NASA's Voyager Golden Record.

Few fictional characters have captured loneliness as powerfully as Eleanor Rigby. She quietly moves through life unnoticed, while Father McKenzie delivers sermons that no one hears, creating one of popular music's saddest portraits of isolation.

Paul McCartney later explained that Eleanor's name came from actress Eleanor Bron and the Liverpool shop Rigby & Evens. The discovery of an actual Eleanor Rigby gravestone in Liverpool only deepened the song's mystique, though McCartney maintained the coincidence was unintentional.

Billie Jean may be one of pop music's most famous women, yet Michael Jackson insisted she wasn't a real person. Instead, she represented several women who falsely claimed that he had fathered their children during the height of the Jackson 5's fame.

Released in 1983 as part of Thriller, the song became a global phenomenon. It also provided the stage for Jackson's legendary moonwalk during Motown 25.

Unlike many legendary song characters, Stagger Lee actually existed. His real name was Lee Shelton, a St. Louis criminal who murdered Billy Lyons during an argument over a hat on Christmas Eve in 1895.

The shocking crime quickly entered American folklore through countless folk songs before Lloyd Price transformed it into a chart-topping hit in 1958. More than a century later, Stagger Lee remains one of the most enduring antiheroes in American music.

Tom Dooley was inspired by Thomas Dula, a Confederate veteran executed in North Carolina in 1868 after being convicted of murdering Laura Foster. His surname was locally pronounced "Dooley," giving the ballad its familiar title.

The Kingston Trio revived the old Appalachian folk song in 1958, turning it into an international hit and helping launch America's folk music revival.

When the narrator of "Lola" meets an intriguing stranger in a Soho nightclub, expectations quickly give way to surprise. Ray Davies crafted one of rock's earliest mainstream stories exploring gender ambiguity, decades before the topic entered popular conversation.

The recording rarely reached British radio. Because BBC rules prohibited commercial product names, Davies had to interrupt a U.S. tour and fly back to London simply to replace the lyric "Coca-Cola" with the now-famous "cherry cola."

Unlike most famous song characters, the Piano Man is really Billy Joel himself. Before becoming a superstar, Joel spent six months in 1972 and 1973 performing under the pseudonym Bill Martin at the Executive Room, a piano bar in Los Angeles, after becoming trapped in a bad recording contract. The song transforms those experiences into a bittersweet portrait of ordinary people searching for escape at the end of another week.

Joel has said that virtually every character in the song was based on a real person, from bartender John to "Paul, the real estate novelist" and Davy, who really was in the Navy. Yet the Piano Man himself became the story's most enduring character: a quiet observer who offers music as a brief refuge for dreamers, lonely souls, and regulars alike. More than fifty years after its 1973 release, "Piano Man" remains Billy Joel's signature song, and its title has effectively become his lifelong nickname.

Standing nearly seven feet tall and missing an arm, Amos Moses roams the Louisiana swamps hunting alligators. Jerry Reed filled the song with colorful Southern expressions and exaggerated storytelling that make Amos feel like an authentic folk legend.

Although fictional, Amos embodies the larger-than-life heroes found throughout American tall tales. His adventures turned the song into one of Reed's biggest crossover hits and secured Amos a permanent place among country music's greatest characters.

Big Bad John hardly says a word, but he doesn't have to. The towering coal miner earns everyone's respect through quiet strength before sacrificing his own life to save fellow workers when a mine collapses.

Jimmy Dean's 1961 ballad became a smash hit, winning a Grammy and inspiring several sequel songs. More than sixty years later, Big Bad John still stands as one of country music's defining working-class heroes.
