Why don't we notice anything unusual in ourselves?

The media regularly alerts us to people with extraordinary abilities that defy rational explanation. It has long been established that human mental abilities are enormous, and the strength of the body is amazing.

But why don't we see this in ordinary life?

Except for people who, from birth, have amazing abilities, and those who develop their potential throughout life (you will find methods for developing superpowers), then we can say that most people do not have any super qualities.

However, this is not true!

When do superpowers appear?

Finding himself in extreme conditions, a person begins to show abilities that shock him. The phenomena of super strength, super speed, super reaction, etc. appear when a person’s life or the life of his loved ones is in danger.

There are cases where fragile women lifted the car after an accident to get their child.

Often in emergency situations all the internal resources of a person are unconsciously activated so that he can survive. Why not always? Because our body and consciousness are not prepared for such overloads.

And yet, even in ordinary life, some of the capabilities of our body are simply amazing. The most interesting thing is that you didn’t know about yourself until now!

This ability allows consciousness to control the work various groups muscles, evaluate relative position parts of the body relative to each other, as well as feel the volume and posture of the body. This explains why a person can accurately touch their nose without opening their eyes.

15. When a person listens to music, heart imitates her rhythm.

These amazing facts about a person confirm that we not only can demonstrate superpowers in extreme conditions, but also amazing in their structure.

But how little we still know about ourselves! Until now, man remains the most unexplored and most unpredictable creature in the Universe.

Notes and feature articles for deeper understanding of the material

¹ Proprioception, proprioception - muscle sense - a sense of the position of parts of one’s own body relative to each other and in space (Wikipedia).

² Prefrontal cortex - part of the cortex cerebral hemispheres brain, which is the anterior part of the frontal lobes (

The famous Greek temple at Delphi is carved with the inscription “Know Thyself.” Ben Franklin said it's easier said than done: "There are three very difficult things in the world: steel, diamond and knowing yourself." Ten unusual facts about a person will help you understand this difficult matter.

10. Your stomach is smarter than you think

The human stomach contains more nerve cells than some animals' brains. The combination of nerve cells in the stomach is so complex that some even call it the “second brain.” Although nerve cells there are also other parts of the body, for example, the palms, which also contain a large number of them; the stomach is unique in that it can “think” for itself - the stomach digests food itself, without unnecessary human intervention. Have you ever been irritated or satisfied for no apparent reason? Couldn't concentrate after have a nice lunch? This is probably the fault of the stomach - another reason to eat right.

9. Humans are as hairy as chimpanzees.

This statement may not seem true when you look at yourself in the mirror (unless you suffer from hypertrichosis), but we are actually just as hairy as other primates. Just like chimpanzees, our bodies are covered with hair, only shorter and finer than that of our furry cousins. On every square centimeter there are about 100-150 of our bodies hair follicles.

The furriest creature in the world is the sea otter, which has about 150 thousand hairs per square centimeter of body surface.

8. You are a miracle

Biology teachers often start the school year by praising their students: “Well done. You have already completed the most difficult task in your life." Students don't understand what their teachers are saying, so an explanation follows. We all started out as a symmetrical ball of cells - but in the end we all have a back, sides and a torso. How does a ball of cells turn into extremely complex structures, such as eyes, ears and nostrils? The ball should be pulled out, turned over and released into various shapes. The first thing that appears in a person is the anus. Biologists often joke about this.

7. Man is part virus

One of the biggest surprises discovered by the Human Genome Project was how much our DNA has been affected by viruses. Viruses cannot reproduce themselves, so some of them are forced to integrate their DNA into the host cell for further copying. If a virus inserts itself into a sperm or egg, every cell of the resulting organism will contain viral DNA. This has happened so often during human evolution that at least 9% of our genome is a legacy of viruses.

6. A person cannot tickle himself

...unless, of course, he suffers from schizophrenia. Tickling is considered an important part of bonding between people, especially between children and parents. As we grow up, we may not like being tickled - but most people can't help but laugh or flinch when another person touches them in certain places. On the other hand, we can't tickle ourselves because our brain knows what to expect. For schizophrenics, it is difficult to recognize that it is their own touching, so they laugh just as much as if they were touched by someone else.

5. Your body is younger than you

Man is constantly changing. We inhale, exhale, eat and defecate. We are constantly exchanging molecules with the outside world. Unless you're a teenager anymore, chances are there's nothing left in your body from when you were a child. This fact gives rise to interesting question, still discussed by philosophers: if every particle of a person’s body is at the moment the other is whether this person is the same as he was at birth.

4. All people are partially blind

Unfortunately, human eyes have a structural flaw: each of them has a blind spot. This blind spot is large enough to cause problems for those who lose vision in one eye. Fortunately for most of us, paired eyes keep blind spots undetected.

3. A person can count subconsciously

When a person is shown up to four objects, he does not have to count them to understand how many objects he sees. For such small groups of objects, people have an instinctive idea of their number. The Piraha tribe of Brazil has no concept of numbers in their language, so they cannot count, but they can still easily understand numbers up to four.

2. A person may not have free will

People still argue whether we make our decisions ourselves, or whether our decisions are influenced by outside forces. There are many arguments on both sides of this debate, but in this paragraph we will look at an experiment conducted on a patient by Benjamin Libet.

Libet, observing the patient's brain, told him to move his hand whenever he wanted. Libet discovered that the desire to move a hand is registered in the brain even before the person is aware of this desire. This fact shows that perhaps we act impulsively, without actually making any decision. Only then does it seem to a person that he did something of his own free will, since he justifies his action after he performs it.

1. The person has stripes

Many mammals have stripes in their coloring: cats, for example, have very distinct lines or zones that appear when some cells begin to express different genes and pass on their variety to other cells. Humans aren't much different in this regard - it's just that our stripes aren't usually visible. These stripes, called Blaschko lines, appear on the skin when the disease affects only one type of cell without affecting an adjacent type.

It is simply impossible to know everything in the world. And the facts from this collection clearly show how little we know even about our own body and our lives. A moment of learning at Chips.

One in ten of your friends won't live to see 40.

This is precisely the conclusion reached by the authors of the Death Risk Ranking website - students and employees of Carnegie Mellon University. They base their conclusions on statistical data on deaths, taking into account gender, age, place of residence and presence bad habits. Unfortunately, the statistics are merciless: if you have 10 close friends, then one of them will most likely die before he turns 40.

The total length of human hair is 725 km

If the average person does not cut his hair from birth until death, then his hair will grow exactly this long throughout his life. Only the hair on your head counts, of course. But if you don’t shave your beard your whole life, it will only grow 9 meters long.

You won't suffocate in a sealed room

Even if you close a person in a completely sealed room, he will not die from lack of air. And all because a person will die from carbon dioxide poisoning much earlier than all the oxygen in the room runs out.

One of the most mobile muscles in the body is the focusing muscles of the eye.

On average, the focusing muscles of the eye move about 100,000 times a day. That's a lot. For example, to make the same number of movements with the leg muscles you need to walk about 80 kilometers.

The world is not suited for lefties

Only 7% of people in the world are left-handed. Not only do right-handed people live 9 years longer on average, but every year about 2,000 left-handed people die due to operating errors various mechanisms, which are intended for right-handed people.

Over the course of life, bones appear and disappear in our body.

At the moment of birth, there are about 300 bones in the child's body. But by the time a person becomes an adult, only 206 remain. However, there is also the opposite example: all children are born without kneecaps. They form during the first few years of life.

We're all traveling around the world

According to statistics, every person during his life walks a distance that is three times the circumference of the Earth. So if you are over 30 years old, you can easily say that you have already traveled around the world.

You can “travel” without even leaving home

While doing normal household chores, a housewife can walk around the house up to 11 kilometers a day. And this is only if we take into account housewives in prosperous, relatively rich countries. But in Senegal, for example, women spend up to 17.5 hours a week finding food.

Related to apes

It may sound incredible, but there is as much hair on a square centimeter of a human body as there is on a square centimeter of a chimpanzee's body. Although they look much hairier than us.

Our body is the whole world.

The human body is an excellent living environment for many types of bacteria and microorganisms. If you add them together, their total weight will be approximately two kilograms. But why do they like to live inside us so much? It turns out, according to scientific research, chemical composition human blood plasma is very similar to the composition of the prehistoric primordial seas in which life once originated.

The nature of the human body is so unique that scientists still cannot find an explanation for some of the features or reactions of the body to this or that external influence. It’s curious, but every cell in our body plays vital role in everyone's existence physiological process, which maintains life in our body. Researchers still have many discoveries to make related to human body. In the meantime, here are 10 incredible facts about a person that will surely become a discovery for many.

1. The mystery of the brain.

The brain is the least studied human organ, and at the same time the most mysterious. It is known that this is the most energy-consuming part of a person in relation to the body (at 2% of total mass body, the amount of energy it consumes is 20%). The most active brain development occurs between the ages of 2 and 11 years. As you grow older, it is necessary to maintain the state of neurons in a certain form, subjecting the brain to various trainings, like any muscle. human body. One of effective methods to maintain intellectual activity is engaging in an unfamiliar activity and communicating with smarter people.

2. The importance of the lungs and breathing.

Except respiratory function the lungs also have protective features, thereby protecting the heart from beating. Incredibly, despite the seemingly small size of the lungs, their volume reaches 100 sq.m., and in athletes these sizes are significantly larger. Interestingly, the ability to breathe correctly and control inhalation and exhalation has a positive effect on emotional state person. For example, to remove nervous tension you just need to take a few deep breaths and exhale. More intense breathing stimulates metabolism and promotes appetite.

3. Human eyes and view of the world.

The uniqueness of each person’s eyes is evidenced by the pattern of the iris, by which a specific person can be identified. This is one of the most important organs person, since about 80% of information from the outside world comes as a result of visual perception. The eye consists of 107 million light-sensitive cells and has the most active muscles. A person blinks up to 15,000 times a day, thereby exerting a moisturizing and antibacterial effect on the eyeball.

4. Matters of the heart.

The heart is the hardest working human organ, pumping about 1.5 barrels of blood throughout life, which is equivalent to the volume of 200 train tanks. The first cell that contributes to the development of the heart appears in the fetus at 4 weeks of pregnancy, ceasing to function upon death. Full cycle blood circulation in the body occurs in 23 seconds, which occurs thanks to the left side of the heart; but the functions of the right side include complete blood supply to the lungs. The study proved the connection between ecology and susceptibility to heart disease - pure ecological situation significantly reduces the risk of cardiac arrest.

5. The exclusive role of the skeletal system.

Bones are an incredible material that allows humans to move. In addition, the skeletal system contributes to the production of leukocytes and red blood cells, which are so necessary for the full functioning of the body. At birth, a child has about 300 bones, some of which fuse with age, thereby reducing the number to 200. The most fragile elements in skeletal system are the ribs because some of them lack connective cartilage, making them vulnerable to injury.

6. The influence of muscles on the functioning of the body.

Human muscles provide the full functioning of all human organs and systems. IN lower limbs contains half of all elastic tissues, about a third are in the arms, and the remaining 20% are located in the head and torso. The most efficient and enduring muscle is the heart, the fastest is the eye muscle, but the strongest are masticatory muscles. In order to smile, the human body uses 17 muscles, while crying - more than 40, but when walking, about two hundred different muscles are involved.

7. Conditioned reflexes.

No less interesting, which is in a constant process of study, is the system of human reflexes. For example, the first yawn can be observed in a fetus in the 4th month of pregnancy. Interestingly, yawning in adults can be contagious. People who have a developed sense of empathy are able to follow their neighbor's yawn. Another common reflex is sneezing. In addition to the fact that this body reaction slows down heart rate, sneezing is part of the immune process, reducing the likelihood of various diseases.

8. Mental health.

The mental state of each person directly affects his physical well-being. Hormones that are released under stress have a destructive effect on the cells and tissues of the body, as evidenced by many scientific research. It's interesting that environment directly affects the development of depression, to which residents of megacities are more susceptible. One of effective ways improve mental health– is a sport, regular exercise of which helps develop perseverance, relieve stress and improve mood.

9. Man and skin.

The area of skin covering the human body occupies from 1.5 to 2.3 sq.m. Except protective properties, this organ has cleansing, respiratory and heat exchange functions. The thinnest skin is found on human eyelids (0.5 mm) and on the soles of the feet. skin reaches 0.5 cm. Depending on the characteristics of a particular organism, top layer skin, you can count about 100 moles. A lack of melanin in the body contributes to the appearance of freckles, which often disappear by the age of 30.

10. Features of hair.

Despite popular misconception, washing and cutting your hair do not in any way affect hair growth or hair loss. It has been established that about 90% of hair is in the process of growth, while the rest is at rest. Interestingly, hair comes in second place after cells bone marrow by growth rate. Most favorable period to increase hair growth - summer and spring, while in the cold period hair growth slows down.
