The human body is the most intricate machine on the planet, and no matter how long you’ve been aware of this fact, there are still some things you probably don’t know about it yet! While your body may seem like it just goes through the motions every day, there are several fascinating things about it that might surprise you! From the reason why your nails don’t grow to the role our stomachs play in supporting our immune systems, here are 10 astonishing facts about the human body you didn’t know about!
1) The Brain is a Muscle
Yes, it’s true! Your brain is a muscle and it grows stronger when you use it. Every time you learn something new, your brain cells grow and adapt to that knowledge. That’s why exercising your mind is just as important as exercising your body—your mind needs its own workout regimen!
2) Nerves are Faster than Lightning
Though you may think you can react quickly to threats, your brain can process a great deal of information in a short period of time. In fact, it's faster than lightning! Studies show that humans are able to process as much as 10 million bits of information per second.
3) We Only Use 10% of Our Brains
Research has found that our brains don’t use all of their available neurons. The idea goes back to Nobel Prize-winning neuroscientist Santiago Ramón y Cajal, who was so fascinated by how complex and vast the brain was, that he assumed we must be using a lot more of it than we actually are. Scientists now believe that most adults only use 10% of their brains on any given day.
4) You Can Move Your Eyes without Moving Your Head
Did you know that we have six different muscles that control our eye movements? One of them is called a lateral rectus muscle, and it lets us move our eyes without moving our heads. And here’s something else you probably didn’t know: when we take photographs, they aren’t just full of empty space — there are actually around 100 million pixels in each one.
5) There are 7 Different Senses
Although you may only be aware of five, there are actually seven different senses: sight, hearing, taste, smell, touch, and balance. All of these senses play a significant role in ensuring your body functions at its peak and help you move about in your daily life. One sense that many people often overlook is taste – with help from our palates, we are able to make decisions about everything from what to eat for dinner to what type of wine goes best with it.

6) Every Single Person on Earth Is Unique
That’s a fact. The details aren’t especially important, except that it means that your body is (very) slightly different from all of your friends and family. It’s actually more than that; you are literally different from yourself, a year ago.
7) Humans Evolved from Apes
Believe it or not, you and I are actually closer relatives to chimpanzees than we are to rodents. Homo sapiens and chimpanzee species share 99 percent of their DNA. The same goes for gorillas, orangutans, and baboons—all of which share more DNA than rodents do.
8) We Have 3 Main Dense Muscles in our Legs
Although we have 4 main muscles in our legs, two of them are very small and do not get much attention. The large muscles are on the backside of our thighs: The quadriceps femoris and hamstring muscles. These muscles work together to allow us to walk, run, jump and move around quickly while protecting our knee joints.
9) Babies Are Made Through Love Not Science
Babies are made through love, not science. Scientists take sperm and egg cells from two loving people, combine them in a petri dish and watch what happens. This was done over 100 years ago. It took another 150 years to discover that DNA is carried in each cell of every living thing we know. So what makes us human? Is it something special in our DNA or is it love?
10) Nobody Knows What Happens After Death
Nobody knows for sure what happens to a person after death. We do know that no one has ever returned from death, so we don’t know exactly what happens when our bodies stop working. Some cultures believe in an afterlife where souls are reincarnated; others believe that when we die, it’s all over forever.
So We knew that unknown fact about the human beings you might not know about. Please share the blog with your friend. Have a good day.
