9 Things About the Human Body You Probably Didn’t Know

Below, we will tell you 9 things about the human body that you probably didn’t know.
1. You Have the Same Amount of Hair as a Chimpanzee
The average adult body has the same amount of hair (known as fuzz) as a chimpanzee. The difference is that, in the case of humans, our hair is much thinner than that of a chimpanzee. Also, in our case, our hair has lost its original function of protection. The current situation of body hair is definitely due to evolution and wearing clothing for protection against the cold.
2. Why Do You Get Goosebumps?
You have often experienced what is commonly known as goosebumps. This is a pilomotor reflex, a response that humans would do in the past to raise the body hair and protect themselves from cold and other dangers like animals. It was an increase in size, in fact. Obviously, this function is obsolete today. Since we don’t have as much hair on our body, the skin continues having the same response.
3. Years in Blinks
Humans spend an equivalent of five years blinking. As we know, this action is very important for your eyes, since it is used as a protection and care mechanism. Blinking lubricates and rests your eyes, which cannot remain permanently open. Blinking is also a protection impulse, because you tend to do it when an object comes towards your face.
4. Lefties Are Stronger
It may be a result of physics – left handed people are stronger when they apply their strength to counter clockwise things. This means that it is much easier for a lefty to open a jar than a right handed person. However, when closing a jar, when you need to apply opposite strength, right handed people find it much easier to do.
5. The Stomach Stores Acid
Your stomach stores chloric acid, which is produced by the cells found in your stomach. In the industry, this type of acid is highly corrosive, which is why it is used in metallurgy. However, the covering of the mucus wall of the stomach protects you from the damaging effect of the acid, which is why you don’t get harmed by it.
6. We Are a Bacteria Deposit
The human body is a huge bacteria deposit. In fact, calculations state that bacteria greatly outnumbers cells, a proportion of ten to one more or less. Of course, this does not mean that all the bacteria in the body is harmful to your health. There are a few that are beneficial and help your body be in a good state.
7. Naps Are Good

8. A Lot of Dead Cells
Every day, your body gets rid of a large amount of dead cells, mainly from your skin. This amount would be equal to approximately two kilograms of dead skin cells a year.
