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?

You probably know many alcoholic beverages that you enjoy drinking alone or combined in different cocktails, but do you know where their names come from? From whiskey and gin to rum and absinthe, the origins of spirits have fascinating stories to tell. Are you ready to explore them? You will surely learn some curious facts to share at your next party!

Whiskey is one of the most consumed alcoholic beverages in the world. It is produced by distilling malt fermented with cereals such as wheat, barley, corn, and rye, and the resulting spirit is subsequently aged in white oak barrels.

In the Middle Ages, alcoholic beverages were classified into two main groups: "aqua ardens" (burning water) and "aqua vitae" (water of life). Whiskey falls into the category of "aqua vitae." The Latin term was translated into Middle Irish as usque beatha, which in turn derived into usquebaugh, pronounced: "wiskyba," giving rise to "whisky" (Scotland) and "whiskey" (Ireland and the United States).

The word brandy is an abbreviation of brandywine, an English term dating from the early 17th century. It comes from the Dutch brandewijn, meaning "burnt wine" or "burning wine," referring to the distillation process.

Brandy is made from the distillate of wine or fermented fruit pulp, primarily grape skins. There are different types of brandy. Perhaps one of the best known is cognac, a high-quality wine distillate, named after the city in France where it is produced.

Gin is a distilled drink made from juniper berries, among other ingredients. The term gin is an abbreviation of the Old English word genever, which in turn derives from the Dutch jenever and the French genièvre. Moreover, all these words trace back to the Latin word for juniper, juniperus.

This drink emerged among European monks during the Middle Ages as a medicinal liquor. Then, in the 17th century, gin gained popularity in England and transitioned into the modern drink we know and love. Nowadays, gin is used to prepare different cocktails, including Tom Collins, Negroni, and the popular Gin & Tonic.

The first references to this drink date back to the mid-17th century in Barbados, a small Caribbean island with sugar plantations that was under British rule for several centuries. When rum began to be produced on a large scale in the colonies, the English imported it to Europe and popularized it throughout the continent.

There are many theories about the origin of the word rum. The most accepted one suggests that it comes from the English slang word rumbullion which means "great tumult." This term might have originated in the Devonshire area on the southwest coast of England. From rumbullion, it became known as rum in English, rhum in French, and ron in Spanish.

Vodka is an emblematic drink of Eastern European countries and is used to prepare a multitude of cocktails, including the Martini Vesper, Moscow Mule, White Russian, Cosmopolitan, and Bloody Mary, among others. The word vodka comes from the Russian word voda, which means "water." The ending -ka makes it diminutive, translating to "little water."

Vodka is a distillate that comes from the fermentation of potatoes, wheat, barley, grapes, beets, or any plant rich in starch. Originally, the aim was to obtain a simple, alcoholic liquid composed of ethanol and water, with no pretensions in terms of aroma or flavor. It also needed to have a high alcohol content to cope with the harsh Russian winters. Traditionally it has a graduation around 40º, although there are vodkas that reach 80º and up to 96º. It is hard to believe that it’s simply called water!

This distillate made mainly from corn, was first introduced in the United States in the 18th century. The first known producer was Reverend Elijah Craig, a Baptist minister. Legend has it that the clergyman established the first distillery in Fayette County, Kentucky, with the help of a Southern farmer who provided surplus corn from his harvest.

Although it was born in Fayette, this variety of whiskey was named after another nearby county, Bourbon County, where the spirit began to be produced on a large scale. The names of both Kentucky counties have their origin in the same historical figure: Gilbert du Motier, the Marquis de Lafayette, a French aristocrat related to the House of Bourbon.

The word vermouth comes from the German word wermut, which means "wormwood," one of the main herbs used to make this beverage. This fortified wine, flavored with different botanicals (flowers, herbs, roots, and spices), has been used since ancient times for medicinal purposes. However, the modern version we know today was first introduced in Turin, Italy, in the 18th century.

In the 19th century, vermouth became a global trend thanks to the rise of bars and cocktails, as it was —and still is— an essential ingredient to prepare classic drinks such as Martinis, Negronis, and Manhattans.

Tequila is, without a doubt, a staple of Mexican culture and a famous drink around the world. In ancient times, it was considered a gift from the gods. Today it’s served as an aperitif or combined with other beverages and ingredients to prepare cocktails.

This spirit is produced from the distillation of fermented juice obtained from the heart of a plant known as "blue agave." Its name comes from the Nahuatl word Tekilan, which means "place of the workers."

This popular anise-flavored spirit, made from wormwood oil and other herbs, has a high alcohol concentration. With a bitter taste, absinthe’s color is usually pale green. Its name derives from the Latin absinthium, which in turn comes from the Greek apsínthion, meaning "wormwood."

The use of wormwood to make alcoholic beverages dates back to the 1st century, but it was not until the end of the 18th century, in French-speaking Switzerland, that the drink we know today was created. At the end of the 19th century, absinthe, often called "Green Fairy," was the most popular spirit in Europe, enjoyed by all social classes, especially artists and bohemians. However, years later its consumption was limited because it could cause hallucinations, which gave birth to the term absinthism.

Peru and Chile, neighboring South American countries, share many things: the Andes mountain range, common ancestors, customs, and, notably, the debate over the origin of pisco. The true birthplace of this spirit has long been questioned, with both countries claiming it as their own. What we do know is that the name pisco may derive from the Quechua word Pisku, meaning "bird."

Peruvian and Chilean pisco are different varieties but have in common that they are grape distillations, made similarly to brandy and cognac. Despite the ongoing controversy, no one should miss trying a good pisco sour!
