Whether you believe in a divine creator, or you don’t believe in any intelligent being, we should be able to all come to an agreement that the human body is a pretty incredible creation. The fact that our lifespans have nearly doubled in the last one hundred years says a lot about how we have grown, evolved, and developed as a species. But interestingly enough, we don’t know much about our own body, such as how to ticks, what makes it function and other ways that help us just exist. Here are some of the most fascinating facts about the human body that’s sure to get your senses tingling.
Did you know that as we’re born, we are born with 270 bones in our bodies. But as we get older, our bones fuse together and we’re left with about 206 bones total. Our heart beats over 100,000 times a day, and starts beating about 4 weeks after we are conceived. Even if the heart if removed from our bodies, it will keep beating as it functions on its own electrical impulse. Our eyes can see over ten million colors and initially sees everything upside down until the brain flips everything back over. Our nose is pretty amazing, as it is the crucial link to the working of our sense of taste. The nose can remember over 50,000 different scents and associates them with specific memories. That’s why we can be taken back to places, different periods of our life, and more if we smell something that is identical in scent to that memory. The nose also acts as our own air system, by cooling down hot air and warming up cold air as it enters our body.
Then we have skin. We shed about 600,000 particles of skin every hour, which in total equals to about 1.5 pounds per year. Before you go into full gag mode, remember this, by the time we die, especially if in our seventies, about 100 pounds of skin would have been shed in total. Also, if you bite your fingernails, stop as soon as you can, as you are preventing the growth of your nails. Toe and fingernails are made out of a protein called keratin, which is the same thing your hair is made out of. Fingernails grow a lot faster than toenails by about four times. Also, men’s fingernails actually grow faster than women’s.
Have you ever wondered if you could taste numbers and smell colors? There is a phenomenon affecting about 4% of the population called synesthesia, which is the overlapping of senses. It is unknown as to why this sort of phenomenon happens, but it’s rampant enough that scientists are baffled and trying to investigate it.
If you have ever looked up into the stars and wonder if we came from them, then you’re right. Physicists believe that the atoms that make up our skin, organs, and bones, actually came from the universe, making outer space and the stars our origins.
