It is worth continuing to list interesting short facts about a person. In general, humans are unique creatures with their own characteristics. Few people know, but women's hearts beat faster than men's. And right-handed people, according to statistics, live on average 9 years longer than lefties. And about 2/3 of people with a kiss tilt their heads to the right side.
It is also interesting that we forget about 90% of dreams. But by the end of our lives, each of us remembers about 150 trillion bits of all kinds of information.
It is known that in spring, the respiratory rate is approximately 1/3 higher than in autumn. 80% of the heat of our body leaves the head, the total length of blood vessels is 100, 000 kilometers, and the number of enzymes working in our body is seven hundred. And people are the only creatures on the planet that can sleep on their backs. And to go into sleep, they need an average of 7 minutes.

About children
A child is a small person, but something distinguishes him from an adult. And this is proved by some interesting facts about children - short, but no less surprising.
So, for example, an average 4-year-old child asks 450 questions a day. And at about the same age, he begins to become aware of himself as a person of a particular gender and behaves in accordance with his affiliation.
Few people know, but newborns have a natural reflex, which consists in the ability to swim. After a couple of months, he disappears, “is forgotten, ” so the children are subsequently forced to learn this again.
By the way, to find out whether a child has self-consciousness can be quite simple. It is enough to draw a dot on his forehead. And then put it in front of the mirror. If the child began to rub his forehead, trying to get rid of the mark, it means that he already possesses self-awareness and realized that something is wrong with his appearance. The kid just began to touch the mirror, like everything that comes in his way? So, for the time being, his self-awareness is not developed.

And yet, everyone knows that in Egypt there was a whole cult of cats. But few people know how strong he was. So, for example, when a domestic cat was dying, its owners mourned their pet and shaved their eyebrows as a sign of grief. A funeral was held. And the cat was embalmed.
