7 amazing facts about the human body

1. All people are a little blind. Any person in the right and left eye has a point called "blind spot".This part of the eye is completely unresponsive to light. In accordance with the overall size of the eye, the blind area, unfortunately, has quite impressive parameters. It is especially difficult for people who are blind to one eye. A person who does not have any problems with vision, this feature of the structure of the eye does not cause any inconvenience.
2. Our body is covered with the same coat as in primates. The hairline of our body actually has a few differences from the monkey's wool. Only the hair on the human body has a smaller thickness and length, and their location and number completely coincide with the structure of the hair of many primates.
3. The human body is much younger than himself. The human body is subject to a constant and continuous process of change. During all processes of vital activity the organism is in different physical and mental states. It is impossible to return to the initial stage, in which a person stayed even one instant earlier. Some cells die, but new ones appear instead. This process becomes especially intense during puberty. It turns out that the cells that were given to the body at birth, died and were replaced by new ones. In this case, did the person remain himself?

4. There are strips on the human body. On human skin, there are spots and lines that are not visible to the naked eye. These strips are named after the dermatologist Alfred Blaschko, who discovered their presence. The Blashko lines were formed by the migration of skin cells even at the stage of human embryonic development. These bands do not coincide with the lines formed by the circulatory, muscular or lymphatic systems. Their location is pure genetics. And they are noticeable only when a person is ill deprived, one of the types of nevus or chimerism.
5. The stomach of a man is actually also clever. It turns out that a huge number of neutrons are not only in the brain. Moreover, in the intestines and in the stomach, there are even more of them than in the head of some animals. Therefore, we can assume that the stomach is the second brain.
6. DNA and viruses. Statement that in the human genome, along with everything else there are also viruses, puzzled many scientists. Since viruses can not reproduce themselves, they are embedded in the host's DNA, so that the organism copied it. So, if the DNA of the virus is embedded in the egg, the offspring that this cell will create will be affected by the genome of the virus. As a result of the evolution of human DNA, 9% consists of viruses.
7. A person can count intuitively. A person has the ability to perceive quantity on an intuitive level, but only if the number of objects is less than four. For example, two or three subjects do not require an account, since at first glance it is clear how many of them. But the Indian tribe Piracha does not consider objects at all. They perceive a different number of objects through intuition.
