If you consider that there are approximately 5.5 billion people on our planet, and of these, about 3.5 billion are between the ages of 15 and 65, then this is not so much. WHO estimates that the number of sexual contacts leads (every day) to 910,000 conceptions, of which half are unplanned and another quarter are “strongly unwanted”, resulting in 150,000 abortions every day. Additionally, those same 100 million happy minutes lead to 356,000 bacterial or viral infections. So not every act is for good. WHO considers the state of genetic health of the population to be rather mediocre.

Human hair is stronger than lead, copper, platinum and can rival steel in strength. So, with a thickness of 0.05 mm, hair can withstand a load weighing 100 grams, thus, a woman's braid, consisting of an average of 200,000 hairs, can easily withstand a 20-ton load.

Short people live longer than tall people, and the difference reaches 10%.

The top layer of human skin is completely renewed in 27 days.

As scientists have calculated, every person living at the beginning of the 20th century managed to walk an average of about 75,000 kilometers during his life. But modern man walks only 24,000 km. This is understandable - modern people prefer to drive and are always in a hurry.

Man is more perfect than anyone else only in the development of his brain and nervous activity, while our other characteristics (in particular, physiological) remain not at a very high level. Our digestion, stomach, kidneys, and heart are much more primitive and less adapted to environmental conditions than those of our animal neighbors. Moreover, we might have died out, unable to withstand the struggle for existence, if not for our brain.

The weight of a healthy person's brain ranges from 1020 to 1970 grams. A man's brain is 100–150 grams heavier than a woman's brain.

A person senses taste using 3,000 special taste organs located on the tongue. But we are very mediocre “tasters,” since even a pig has 5,500 taste organs, while cows have 35,000, and an antelope has 50,000.

An adult man has from 300 to 500,000 hairs on his body, with blondes having the finest hairs and more of them than brunettes and, especially, redheads, who have the coarsest hairs and the fewest of them.

The human body consists mainly of water. It contains 100 trillion cells, which contain 10 kg of oxygen, carbon, hydrogen and nitrogen, 2 kg of calcium and phosphorus, several tens of grams of potassium, sulfur, sodium, chlorine and 6 g of iron.

The longest bone is the femur (27.5% of height), the shortest is the “stirrup” in the ear (3–4 mm). A man's total muscle weight is 40%, a woman's is 30%.

The total length of blood vessels is 100,000 km. Blood is distributed as follows: 25% in the muscles, 25 in the kidneys, 15 in the intestinal walls, 10 in the liver, 8 in the brain, 4 in the coronary vessels of the heart, 13% in the vessels of the lungs and other organs.

Starting from the thirteenth year of life, 30–50,000 nerve cells die every day in a person. With age, his weight decreases.

For a woman, periods of intense creativity range from 2 to 3 years and from 5 to 6 years, and the maximum rise occurs at 24, 29, 39, 40, 44, 46 and 52 years. A man has creative productivity cycles of two to three and five to seven years. There are longer ones: 10–11 and even 14 years. There is a hypothesis that the rise of creativity is closely related to solar activity.

Western researchers have calculated the time spent on human life needs. As it turned out, the “average” person spends 3 years of his life waiting, dressing and washing take him another 5 years, talking on the phone takes a year. A person spends 6 years eating, another 5 years traveling, and another 9 years entertaining.

There are approximately 125,000 hairs on the human head. And over the course of his life, 1.5 million hairs fall out and grow back.

The human brain consists of 10 billion nerve cells and has the ability to remember 86 million pieces of information. About one hundred thousand chemical reactions occur in the human brain every second. In 0.05 seconds the brain recognizes an object whose image has been recorded by the eye. The maximum speed of signal transmission from neuron to neuron in the brain is 400 km/h. A piece of human skin with an area of ​​6.5 square centimeters contains 25 meters of nerve fibers, more than a thousand nerve endings, 65 hair follicles and 6 meters of blood vessels.

In humans, the total area of ​​receptors, that is, receivers that respond to smell, is only 4.8 square centimeters, while in a dog it is 64.3; in a shark it is 130, and in a rabbit it is equal to the total surface area of ​​its body.
