Nature has ordained the following proportions in the structure of the human body:
The length of four fingers is equal to the length of the palm, four palms are equal to the foot, six palms are one cubit, four cubits is the height of a person.

Four cubits are equal to a step, and twenty-four palms are equal to the height of a person.
If you spread your legs so that the distance between them is 1/14 of a person's height, and raise your arms so that your middle fingers are level with the top of your head, then the center point of your body, equidistant from all limbs, will be your navel.

The space between your spread legs and the floor forms an equilateral triangle.
The length of your outstretched arms will be equal to your height.

The distance from the roots of the hair to the tip of the chin is equal to one tenth of human height.
The distance from the top of the chest to the top of the head is 1/6 of the height.

The distance from the elbow to the fingertips is 1/5 of the height, from the elbow to the armpit is 1/8.
The length of the entire arm is 1/10 of the height.
The beginning of the genitals is located right in the middle of the body.
The foot is 1/7 of the height.
The distance from the toe of the foot to the kneecap is equal to a quarter of the height, and the distance from the kneecap to the beginning of the genitals is also equal to a quarter of the height.
The distance from the tip of the chin to the nose and from the roots of the hair to the eyebrows will be the same and, like the length of the ear, equal to 1/3 of the face.

The human brain generates more electrical impulses per day than all the world's phones combined.

The average human brain weighs 1.4 kilograms, and size in this case really doesn’t matter: Einstein’s brain weighed 0.2 kg less than normal, so if a friend’s hat is too small for you, don’t flatter yourself - it’s not a fact that you’re smarter than him .
Despite its small volume and the fact that the brain is 90% water, it consumes 25% of all the oxygen and sugar the body needs.
The phenomenon in which a person loses the ability to see due to strong light is called “snow blindness.”

In psychiatry, a syndrome accompanied by depersonalization, impaired perception of time and space, one’s own body and the environment, is officially (!) called “Alice in Wonderland.”

During life, the human small intestine is about 2.5 meters long. After his death, when the muscles of the intestinal wall relax, its length reaches 6 meters.
Humans have approximately 2 million sweat glands. The average adult loses 540 calories with every liter of sweat. Men sweat about 40% more than women.

If you like to download free books from the Internet, keep in mind that our eyes perceive printed information from a computer screen 25% slower than from a paper sheet.
If people grew throughout their lives, their average height would be 6 m and their weight would be 255 kg.

About the length, we can also say that the length of the foot is equal to the distance between the wrist and elbow (this is for men). Legs are needed not only so that there is no truth in them. If you use them for their intended purpose, then by the age of 60 you will have walked about five Earth equators, and the length of your legs is associated with the risk of heart disease: If your legs are 1.5 cm shorter than your neighbor's, your risk of cardiovascular disease is 10% higher.
The cough speed is 900 kilometers per hour. This refers to a stream of air with different droplets that escapes from the lungs. This is higher than the speed of a modern airliner, so do not cough against the direction (flight) of the plane - it may lose thrust and fall.

Our saliva develops at a slightly lower speed when sneezing - 177 kilometers per hour.
By the way, about drool. Did you know that during a lifetime a person produces 23,600 liters of saliva, and he sweats 18,000 liters of sweat.
Plug your nose: for the whole life a man passes gas 209,000 times, and a woman 232,000 times, but don’t judge beautiful ladies harshly, they just live longer than men (you have to pay for everything!).
Nails grow at a rate of 0.123 mm per day. The rate of nail growth does not depend on the time of year, location and nutrition of a person. But with age, growth slows down and at 61 years old it is only 0.1 millimeters per day, and after another six years - 0.095 millimeters per day.

In an adult, the heart pumps about 10,000 liters of blood per day. During one blow, approximately 130 milliliters are thrown into the aorta. The normal heart rate at rest is 60-80 beats per minute, and in women the heart beats 6-8 beats per minute more often than in men. During heavy physical activity, the heart rate can accelerate to 200 or more beats per minute. For comparison: the pulse rate of an elephant is 20 beats per minute, that of a bull is 25, that of a frog (a cold-blooded animal) is 30, that of a rabbit is 200, and that of a mouse is 500 beats per minute.
The total length of blood vessels in the human body is approximately one hundred thousand kilometers.

This is how blood is distributed in the body at rest: a quarter of the total volume is in the muscles, another quarter in the kidneys, 15% in the vessels of the intestinal walls, 10% in the liver, 8% in the brain, 4% in the coronary vessels. heart, 13% - in the vessels of the lungs and other organs.
36,800,000 is the number of heartbeats in a person in one year.
During an average life, the heart beats 330,000,000 times (just think about this colossal figure!). Take care of yourself!

Human hair is approximately 5,000 times thicker than soap film.
The length of hair on the head grown by the average person over the course of a lifetime is 725 kilometers.
Blondes grow a beard faster than brunettes.
The hair growth rate is approximately 0.3-0.35 mm per day, that is, 12 cm per year, the lifespan of hair is 2-4 years; Considering that the total number of hairs on the head of redheads is about 80,000, brunettes - 100,000, and blondes - 140,000, then over the course of a lifetime, the average person grows hair to a total length of up to 1,008,000 kilometers (you can wrap the earth around the equator 22 times).

Every day a person loses from 30 to 120 hairs.
Hair grows fastest between the ages of 15 and 30. Hair growth slows down after 50. In summer, by the way, hair grows faster than in winter.

The hair can be stretched to 1/5 of its length, and after that it returns to its original state.
The strength of the hair is comparable to aluminum and can withstand a load of 100 to 200 g.
Hair is hygroscopic, that is, it is able to absorb moisture - this is due to the structure of the hair.
Hair is resistant to weak acids, but does not tolerate alkaline compounds well.
Hair can accumulate certain substances, which allows it to be used as an identifier.
The lifespan of hair is different: on average, men have 2 years on their heads, and women have 4-5 years.
Redheads have the thickest hair, but less hair than others.
Black hair is the largest of all, and can be 3 times thicker than blonde hair.
The baby's first hairs appear in the womb, at about 4-5 months of pregnancy.
Hair grows at an average rate of 0.4 mm per day.
As you age, your hair becomes shorter and thinner.
Hair is mainly composed of proteins.
The hair follicle has three phases of life: anagen (hair growth phase), catagen (transition phase), telogen (resting phase).
Women are less likely to go bald than men because women's hair roots sit 2 millimeters deeper in the skin than men's.
Human skin is 95% covered with hair.
During the day, each hair lengthens by about 0.35 mm.
The optimal water temperature for washing hair is 35-45°C.
84% of women improve their mood by going to the hairdresser.
According to American experts, 60-70% of men and 25-40% of women suffer from hair loss.
From each hair follicle, about 20 hairs grow sequentially throughout life.
There are 300 thousand remedies for hair loss in the world - more than remedies for any other disease.

A human being is made up of more than 100000000000000 cells (read "one hundred trillion"). For comparison:
There are approximately 6,500,000,000,000,000 (six and a half quadrillion) cells in an elephant.

Humans are 60% water. It is distributed unevenly: for example, in fatty tissues there is only 20% water, in bones 25%, in the liver 70%, in muscles 75%, in blood 80% and in the brain 85% of water of the total weight.
When looking at these figures, one is struck by the apparent paradox - there is less water in liquid blood than in the rather dense brain. But it’s not only about the quantity, but also about the “packaging” of water.
It is known that jellyfish are 98-99% water, however, the jellyfish does not dissolve in the sea, it can be picked up.

The remaining 40% of the human body weight is distributed as follows: proteins - 19%, fats and fat-like substances - 15%, minerals - 5%), carbohydrates - 1%.

Of the elements that make up our body, the most important are oxygen, carbon, hydrogen and nitrogen. There are about 70 kilograms of them in the adult human body. There is also a lot of calcium and phosphorus - together there are almost 2 kilograms of them, they are part of the bone, ensuring its strength. Potassium, sulfur, sodium, chlorine are contained in quantities of several tens of grams. Iron in a person is only about 6 grams, but it plays an extremely important role, being part of hemoglobin.

Oddly enough, it is not possible to indicate the exact number of bones in the human skeleton. First, it varies somewhat from person to person. Approximately 20% of people have abnormalities in the number of vertebrae. One person out of every twenty has an extra rib, and men have an extra rib about 3 times more often than women (contrary to the biblical legend of the creation of Eve from Adam's rib). Secondly, the number of bones changes with age: over time, some bones grow together, forming dense sutures. Therefore, it is not always clear how to count bones. For example, the sacrum bone clearly consists of five fused vertebrae. Should we count it as one or five? Therefore, reputable manuals are careful to indicate that humans have “slightly more than 200 bones.”
The longest bone is the femur, its length is usually 27.5% of a person's height. The shortest is the stapes, one of the bones that transmit vibrations of the eardrum to the sensitive cells of the inner ear. It works like a lever, increasing the pressure of sound waves. Its length is only 3-4 millimeters.
The smallest muscle is the stapes muscle. When the sounds are too strong, she turns the stirrup so that the ratio of the lengths of the arms of the bone-lever changes, and the sound amplification factor drops.

It is impossible to accurately indicate the number of muscles. Experts count from 400 to 680 muscles in humans. For comparison: grasshoppers have about 900 muscles, some caterpillars have up to four thousand. The total muscle weight in a man is about 40% of body weight, and in a woman it is about 30%.
In a calm state, lying down, a person consumes 400-500 liters of oxygen per day, making 12-20 inhalations and exhalations per minute. For comparison: the respiratory rate of a horse is 12 respiratory movements per minute, a rat is 60, and a canary is 108.
In spring, the respiratory rate is on average one third higher than in autumn.
Each red blood cell contains about 270 million hemoglobin molecules. The life span reaches several months (there are several types of leukocytes, which is why their life spans are so varied). In an adult, a billion red blood cells, 5 billion white blood cells and 2 billion platelets die every hour. They are replaced by new cells produced in the bone marrow and spleen.
Approximately 25 grams of blood are replaced per day.
An adult's bone marrow, the loose mass that fills the internal cavities of some bones, weighs on average 2,600 grams. Over 70 years of life, it produces 650 kilograms of red blood cells and a ton of white blood cells.
The human nervous system contains about 10 billion neurons and about seven times more service cells - supporting and feeding cells.
Only one percent of nerve cells are engaged in “independent work” - they receive sensations from the external environment and command the muscles. Ninety-nine percent are intermediate nerve cells that serve as amplifier and transmitter stations.
The largest human nerve cells are 1000 times larger than the smallest ones. The thinnest nerve fibers are only 0.5 micrometers in diameter, the thickest are 20 micrometers.
More than half of all neurons are concentrated in the cerebral hemispheres.
The total area of ​​the cerebral cortex varies from 1468 to 1670 square centimeters.
In the cranial nerves, 2,600,000 nerve fibers enter the brain and 140,000 exit. About half of the exiting fibers carry orders to the muscles of the eyeball, controlling fine, rapid and complex eye movements. The remaining nerves control facial expressions, chewing, swallowing and the activity of internal organs. Of the incoming nerve fibers, two million are visual.

The average normal visual acuity is 0.0003 arc minutes, that is, the eye is able to distinguish a well-lit object with a diameter of one tenth of a millimeter at a distance of 25 centimeters. But if the object itself glows, it can be much smaller.
A hole with a diameter of 3-4 thousandths of a millimeter, pierced in a sheet of tin, behind which a light bulb is lit, is clearly visible to the normal eye.
The eye is capable of distinguishing 130-250 pure color tones and 5-10 million mixed shades.
The flash frequency at which the flashing light appears to be burning evenly to the eye is 15 per second for rods and 71-90 for cones.
Complete adaptation of the eye to darkness takes 60-80 minutes.
In a minute, 740-750 milliliters of blood flows through the brain.
Blood cells constantly die and are replaced by new ones. The lifespan of an erythrocyte is 90-125 days, and that of a leukocyte is from several hours to several days.
Starting from the thirtieth year of life, 30-50 thousand nerve cells die every day in a person. The main dimensions of the brain decrease. With age, the brain not only loses weight, but also changes shape - it becomes flatter. In men, brain weight is maximum at 20-29 years old, in women - at 15-19.
The mass of the human brain is 1/46 of the total body mass, the mass of the elephant's brain is only 1/560 of the body mass.

The finger is capable of feeling vibrations with an amplitude of two ten-thousandths of a millimeter.
The average surface area of ​​human skin is about 2 square meters. It is necessary to know this when prescribing certain medications and medical procedures. To calculate the skin surface in the clinic, the following formula is usually used:
body surface = (body weight X 4) + 7
The weight should be taken in kilograms, the surface is obtained in square meters. There are more accurate formulas that take growth into account, but the calculations using them are much more complicated and are used less frequently.
In one minute, 460 milliliters of blood passes through the skin.
The skin contains 250 thousand cold receptors, 30 thousand heat receptors, a million pain endings, half a million touch receptors and three million sweat glands.
There are about 25,000 cells in the inner ear that respond to sound. The range of frequencies perceived by hearing lies between 16 and 20,000 hertz. It decreases with age, especially due to decreased sensitivity to high-pitched sounds. By the age of 35, the upper limit of hearing drops to 15,000 hertz.

The ear is most sensitive to the range of 2000-2300 hertz. The best ear for music (the ability to distinguish pitch) is in the region of 80-600 hertz. Here our ear is able to distinguish, for example, two sounds with a frequency of 100 hertz and 100.1 hertz. In total, a person distinguishes between 3-4 thousand sounds of different heights.
We become aware of sound 35-175 milliseconds after it reaches the ear. It takes another 180-500 milliseconds for the ear to “tune in” to receive a given sound and achieve the best sensitivity.
There are about 9,000 taste buds on the tongue. The best temperature for their operation is 24 degrees Celsius. (Gourmets should take this into account!)

The area of ​​the olfactory zone of the nose is 5 square centimeters. There are about a million olfactory nerve endings located here. In order for an impulse to arise in the olfactory nerve fiber, approximately 8 molecules of an odorous substance must reach its end. For the sensation of smell to occur, at least 40 nerve fibers must be excited.

When chewing food, the jaw muscles develop a force of up to 72 kilograms on the molars, and up to 20 kilograms on the incisors. Chewing bread requires an effort of 25 kilograms, chewing fried veal requires 15 kilograms.
For one square millimeter of the gastric mucosa there are about one hundred glands that secrete digestive juice.
The small intestine, where digested food is absorbed into the blood, has about 5 million villi on its inner surface - the finest hair-like outgrowths through which nutrients are absorbed.
A sip of water - is it a lot or a little? Numerous measurements have shown that a man swallows an average of 21 milliliters of liquid in one gulp, and a woman swallows 14 milliliters.

Thirst occurs when water loss equals one percent of body weight. A loss of more than 5% can lead to fainting, and more than 10% can lead to death from desiccation.
A fresh fingerprint weighs about one millionth of a gram. It consists of water, fats, proteins and salts secreted by the skin.
Even stern men shed 1-3 milliliters of tears every day. Tears are constantly produced by the lacrimal glands and moisturize the cornea of ​​the eye, protecting it from exposure to air and dust.
There are at least 700 enzymes working in the human body....

Squid sperm
This case occurred with a 63-year-old resident of South Korea. While eating half-raw squid in a restaurant, she suddenly felt a disgusting taste in her mouth, and then the urge to vomit. Time passed, but she did not get better, and she had to see a doctor. He told the victim that she had caught a squid spermatophore on her tooth - the receptacle for the male’s sperm. Squid sperm, as it turns out, are incompatible with the human body - at least without harm to this organism. Fortunately, they cannot develop in it, so parting with the vile food was not particularly painful for the victim.

57 fly larvae
Not everyone knows that a fly is an insect that is deadly to humans. At least if it gets stuck in his ear. This is exactly what happened to a 92-year-old patient, from whose ear doctors removed a dead fly and 57 live larvae. The fly apparently got stuck in the ear when it was time for it to lay eggs. A few days later, when the developing larvae began to cause unbearable pain to the patient, she nevertheless turned to the doctors, who saved her from suffering.

Several hundred larvae
The story of 57 maggots in the ear is nothing compared to the case of a Hindu who went to the doctor about an ear infection. After examining the patient, the doctor realized that it was not an infection - hundreds of small fly larvae were simply devouring the man’s flesh alive! He had to go through a very painful procedure to remove them, and then undergo a long treatment.

Plants in the lungs
Massachusetts resident Ronan Swedan could not get rid of a cough for many months. Doctors suspected he had a tumor in his lungs, but after taking an X-ray, they discovered a much more exotic cause of his suffering. Apparently, Ronan once swallowed a pea, which by accident went into the respiratory tract... and sprouted in the lungs! The man had to undergo surgery, which relieved him of the pain in his lungs.

Fish in the bladder
Men who find themselves on the banks of the Amazon or Ganges should under no circumstances urinate in the water! Local small fish are attracted by the smell of urine - so much so that, when they swim up to the violator of sanitary standards, they swim to the source of the aromas, penetrating the penis and urethra and causing a lot of suffering to the victim. Indian doctors recently described a case where such a fish, only 2 centiaters long, swam through the urethra into the bladder of a local young man, and in order to remove the source of suffering, he had to undergo a complex surgical operation.

Fish in the lungs
Tourists are often warned not to drink water from Indian rivers. Local residents are much more indifferent to this - and in vain! Recently, a boy was admitted to an Indian hospital with breathing problems. An X-ray revealed that in his lung there was... a live fish 7 centimeters long! As it turned out, the victim was playing with friends on the river in a game popular among local boys: “Who will swallow the live fish?” The young daredevil managed to swallow it - but the fish went into the wrong throat, and as a result the boy had to go under the surgeon’s knife.

Acne in the bladder
This story happened to an elderly Chinese man who was tempted by a “fish peeling” - a bath with sea eels, which, according to the organizer of the event, were supposed to bite particles of dead skin from the body. But one of the eels chose to act differently - and climbed up the ureter directly into the patient’s bladder. When the surgeons removed the eel and measured it, it was almost 15 centimeters. One can imagine the suffering of the unfortunate man!

Acne in the intestines
This wild story also happened in China and also with an eel. Only in this case, the victim released it into the body of his own free will. While watching pornography, a Chinese man decided to give himself exquisite pleasure - and threw a live eel into his rectum! It is not known what he was counting on, but the eel, feeling trapped, tried to make its way to freedom, for which it gnawed through the pervert's large intestine - and immediately became entangled in the internal organs. The sufferer was brought to the hospital with severe internal bleeding, and doctors had to spend a lot of effort to save his life.

Larvae in hair
This happened to a Colorado resident in 2007. The man suffered from itching on his scalp for many weeks. Shampoos and anti-dandruff products had no effect. The itching turned into pain, which soon became completely unbearable. Only then did the unfortunate man go to the doctor, who discovered that a gadfly had laid larvae under the man’s hair. They grew and fed right under the victim's scalp, and were already quite large. As soon as the doctors removed them, the patient immediately began to recover.

Cockroach in the ear
Small flies and midges get into the ears of children and adults quite often. However, Australian Hendrik Helmer can be considered a record holder in this regard: when he came to the doctor complaining of unbearable pain in his ear, the doctor removed an almost three-centimeter cockroach from his ear canal! Due to the size of the insect, this was not so easy to do, and the doctor had to work a lot with tweezers in order to evict the uninvited guest and not damage the patient’s eardrum. Fortunately, everything ended well.

Own twin
In medicine, there are only a few such cases, and each of them makes you shudder with horror and disgust. One of them occurred in June 1999 in India. A man named Sanju Bhagat learned during a routine examination that his voluminous belly was not at all the result of his passion for beer and sweets. As it turned out, in the stomach of 36-year-old Bhagat lived his half-formed twin brother, who was underdeveloped during the prenatal period. The surgeons relieved Bhagat of this burden, after which the man experienced great relief.

Basically, pathogenic organisms consume nutrients that a person receives through food. Perhaps this behavior of “uninvited guests” explains the fact that many people who lead a healthy lifestyle, monitor their health and nutrition, do not get the desired result, since these “parasites” take away all the best, leaving a person with only a small particle of useful substances. These creatures are so cunning that they often disguise themselves as other diseases, and a person can go to doctors for years, but not notice a positive result in treatment.

Foreign organisms can enter the human body in several ways, but most often infection occurs through:

For the first time, the pinworm enters the child’s body with dirty hands, through dishes, linen, and toys of other children.
