We share DNA with Bananas
You’ve probably heard that humans differ from chimpanzees by only one chromosome. DNA is such a precise system that the slightest change can transform you into a whole new species. As it turns out, humans share 50 percent of their DNA with a delicious banana.
Most of our Cells are not Human
Of the billions of cells that make up the human body, only 10 percent are actually “human.” The remaining 90 percent are made up of various fungi and bacteria. They help our body to survive.
There Is a Whole Ecosystem in Our Navel
We cannot see them, but the human body contains trillions of tiny organisms, such as bacteria, millions of which live inside the navel. There are so many bacteria in the human navel alone that they might type an associate degree scheme.
We’re Completely Covered in Hair
In nature, there is no such thing as a bald person. Every human being has the same amount of hair per square inch of the body as a chimpanzee. These hairs are so short and thin that most of them are almost impossible to see with the naked eye.
We Have a Smart Stomach
The stomach is a very smart organ that can “think” without the influence of the brain. It digests food without our intervention. The acids in the gut are very strong, and even zinc can be digested. It is good that the stomach cells have time to regenerate faster than the effects of acids.
Our Sneezes Are Stronger Than the Wind
Want more interesting facts about the human body? Sneezing has a practical function. It clears any congestion in the nasal cavity and throat. The force of sneezing is so great that it exceeds the speed of 100 miles per hour.
We Only Need One Nostril to Breathe
Most people breathe only one nostril at a time. The “leading” nostril changes approximately every 4 hours. If you concentrate, you will be able to notice which nostril you are breathing right now.
We Are All Super-Strong
Our muscles are stronger than we think. The body limits the amount of force it can use to protect our muscles and tendons from damage. This restriction is removed during the adrenaline rush into the blood. At such times, many people can lift huge rocks and cars.
Our Brains Feel No Pain
The brain can perceive and process feelings of pain from other parts of the body. However, the brain itself is incapable of feeling pain. It doesn’t have pain receptors like those in your hands, feet, or other parts of your body.
Our Tears Understand Our Emotions
You produce tears with different patterns depending on the situation and the reason you are crying. Emotions such as sadness, anger, grief, shame, guilt, sadness, or happiness lead to a complete change in the molecular structure of tears. Every tear is molecularly different.
We Glow in the Dark
Here is one of the most amazing facts about the human body. Like deep-sea creatures, humans are naturally bioluminescent, which means we glow in the dark. However, the light we release is incredibly weak, so that human eyes cannot distinguish it.
We Have More Than Five Senses
People have five basic senses. We also have over ten other important senses such as balance, temperature, pain, and time. We also have inner feelings of suffocation, thirst, and fullness.
Our Nerve Impulses Move at a Speed of 250 Miles per Hour
The sensation of pain comes instantly when you touch something hot or prick with a needle. Thanks to our highly developed nervous system, we can respond in less than a millisecond to things we should stay away from.
Nerve impulses are so fast that electrical signals travel to and from the brain at an average speed of 250 miles per hour.
Our Skin Never Stops Growing
The human body is made up of cells. Considering that we are producing 25 million new cells every second, we regularly have new layers of skin. In a lifetime, people lose up to 40 pounds of skin.
We See Farther Than We Think
Our eyes will never be as keen as an eagle’s. However, the human eye can see so sharply that if the Earth was flat, we could see the flickering of a candle up to 30 miles away.
