These abilities are a testament to the incredible work of evolution that has made us the unique creatures we are. Whether conscious of them or not, our bodies are constantly performing amazing feats, and it is worth taking a moment to appreciate our incredible capabilities.

Both species have enamel on their teeth, which contributes to their durability. Interestingly, sharks cannot develop cavities as humans can. While this may be due in part to their saltwater environment, it’s clear that both sharks and humans have impressive teeth.

But did you know that the electrical power produced by the brain is enough to power a light bulb? It’s truly amazing to think about the potential of this incredible organ and the many mysteries that remain to be uncovered about how it works.

Symptoms of this condition include emotional stress, chest discomfort, and shortness of breath. These symptoms are commonly experienced by those going through a breakup. However, unlike a regular breakup, heartbreak syndrome doesn’t pass easily. It can even lead to further health issues. So, it’s important to take care of your heart and well-being during difficult times

This natural resilience of hair allows it to withstand various chemicals and acids without degrading. In fact, hair seems to be unaffected by these substances, making it a material that can withstand the test of time. So, if you want something to last, consider using hair as a building material.

This simple action has a surprisingly refreshing effect on the body. By cooling off your thumb, you can calm your nerves and feel more relaxed. If you’re feeling overwhelmed, give this technique a try and see if it helps you find some relief.

A study conducted by scientists found at least 615 different types of bacteria in the human body. The same study also revealed that the number of bacteria in the mouth can easily reach into the billions.

But why is this the case? The reason is that as we grow older, our bones begin to fuse. This process continues until we reach adulthood, at which point our bones have become much more solid and sturdy. This helps to support our body weight and allows us to move around freely.

Another interesting fact about the skin is that if peeled off and stretched out, it could cover around 22 square feet. While this may be unsettling to think about, it’s important to remember the crucial role that the skin plays in protecting the body.

As we all know, the kidney is crucial because of its work. It helps our body function well and keeps our blood healthy. A typical body has about seven to eight liters of blood in total.

You won’t be able to exercise in the same way that someone with two lungs can, and the same is true for the kidneys. However, you can still live a long and fulfilling life.

The heart contracts 100,000 times per day and is constantly pumping blood. Just as sharks never stop swimming, your heart never stops working to keep blood flowing around your body. Exercisers can pump blood six times faster than the average person.

While you won’t be able to do it, trying to achieve this impossible feat could put you in danger of choking. So, we ask that you take our word for it. If you want to test the theory, dust off your old anatomy book and take a look at the details of the human throat.

Additionally, psychological changes occur when we are immersed in water, and they intensify the deeper we go. This has led academics to assume that humans have a history of swimming and deep diving.

In most bodies, the kidneys are positioned differently, with the left one slightly higher than the right. This is a nice reminder that perfect symmetry isn’t natural. Inside and out, we are beautiful just the way we are!

Enzymes continue to act after death, feeding on fluids created during autolysis, a process that occurs when a person dies. It’s an efficient system but it’s best not to dwell on it for too long!

Even if the chances of someone asking for a tongue print are quite remote, it’s still fascinating to know that they exist. To get a clear print of a tongue, 3D imaging would be required.

A human body, according to scientists, carries three to five pounds of bacteria with it at all times. This bacteria is enough to fill a full soup can and equates to around 1% to 2% of your body mass.

Cancer is a proliferation of faulty cells that haven’t triggered this self-destruct mechanism. So, if all is going well inside your body, it’s quite possible that cancerous cells emerged but quickly destroyed themselves, with you being none the wiser.

The majority of astronauts return from space slightly taller than when they left. Those who spend a year in space gain up to two inches in height. However, as the effects of gravity take hold again, they generally lose this height. It’s fun while it lasts, though!

The light is just too faint to be detected with the human eye. It takes the right instrument to pick up our glow. Luckily, our eyes are capable of seeing the bioluminescence of some creatures, like jellyfish and fireflies. They have this property in much higher doses than we do.

Without oxygen, you will go unconscious after a few minutes, but your brain will continue to work for a long time after that. Even if your heart stops beating, your brain can keep going for another six minutes.

This pressure has the potential to send blood flying 30 feet across a room. Of course, if that’s happening, you won’t have time to marvel at the distance you achieved! You’ll be hoping that a trained medical professional is on hand to help you out.

Though the difference in brain size isn’t significant, it can be noticed by many women. Hence the term “baby brain.” When the infant is born, however, these alterations begin to reverse almost immediately. So, don’t go teasing your poor mom about having a small brain!

Those fingerprint designs will never change, and each and every fingerprint is absolutely unique to its owner. How amazing is it that these signatures develop at such an early stage in life? We can’t help but wonder when the unique tongue print we learned about earlier will develop!

The skull, as it turns out, is quite small compared to the surface area of the human brain. Thankfully, our brains are able to comfortably work in this compact space. However, if you were to smooth out every wrinkle, your brain would reach an impressive size.

Stardust makes up 93 percent of the mass of a person’s body. While many doubters may not accept this, it has been independently validated by scientists on multiple occasions. Isn’t it kind of beautiful to think of yourself as an ancient cosmic being?

In a way, yes – gravity has a lot to do with it. Over the course of our lives, the discs in our vertebrae are gradually flattening at a rate that is barely apparent. However, after the age of 30, most people will lose about half an inch every ten years!

Similarly, the glands work harder than usual when you eat a meal. Though you’re rarely aware of this bodily function, it’s always working away, protecting your mouth and keeping it at an ideal pH level. So, don’t be too grossed out!

There are no arteries connecting the cornea to the rest of the body. Tears, nerve fibers, and aqueous humor (a translucent inner-eye fluid) provide each of your corneas with the nutrition they need to function.

The molars in your mouth can exert up to 200 pounds of force each time you take a bite, and a big part of this power comes from your jaw muscles. So, next time you take a bite out of an apple, say thank you to your masseter!

The material travels about when we sleep, allowing our spines to decompress and lengthen out again. So, when you get up each morning, take a moment to appreciate yourself at your full height!

Taste buds, in fact, only endure around ten days before they are replaced. However, as you age, your body puts less effort into replacing the dying taste buds. So, by the time you hit 60, you’ll likely have half the taste buds you had when you were younger.

To put things in perspective, the average human body temperature is 98.6 degrees Fahrenheit. Any temperature exceeding 100.4 is cause for alarm, and most people’s organs begin to fail when their temperature exceeds 107.

This could be due to the fact that blinking keeps the eyes lubricated, and babies’ eyes may not require as much lubrication as adults. The next time you’re babysitting, pay attention to how much the little one blinks. You’ll soon see we were telling you the truth!

Teratomas are generally found in ovaries or testicles and may be benign or malignant. The creepiest thing about a teratoma is that it can grow teeth. This is due to the fact that they develop in regions of the body that contain plenty of stem cells.

Because we blink so frequently on a daily basis (even if a blink just lasts a fraction of a second), most of us have our eyes closed for around 10% of the time we are awake. It’s nice to know our eyes are getting plenty of breaks!

The number of soap bars produced would largely be determined by the amount of fat stored in your body. This seems like an efficient use of fat. However, the donation process might be a little unpleasant!

Demodex, a type of mite found in our eyelashes, is likely the source of a variety of skin conditions. However, for most people, these little mites are benign hitchhikers. How do you feel about having little critters living in your eyelashes?

Some birds and reptiles have a pink corner in their eyes that is very similar to ours. For them, it is a translucent inner eyelid. It’s likely we had a similar bodily feature, but after millions of years of development, there isn’t much left of it.

Despite the fact that these microbial populations may have a negative impact on our health, they are still understudied. Of course, there are good bacteria too, so we shouldn’t worry too much about the colonies we’re carrying around (at least, we hope we don’t have to worry)!
