Determination of the human age

Sometimes a person does not look like his own year. Younger or older. But experts as accurately as possible learn about how his body works, how much he is able to work, without even looking at his passport. There are various ways for this. This is our story today.

Calendar and biological

Usually by the word "age" we mean the number of years lived. This is passport information (or chronological). But we are all different! Some lead a healthy lifestyle, others - on the contrary. Someone thanks to heredity for a long time keeps a store of energy, and nothing hurts them. Some grow old early. Together, these indicators, brought together, are a biological "experience". A leaflet in the document has little to say about the health and ability to work of this or that citizen.

As a rule, the individual characteristics of people differ from the average.

Steps of our century

Before talking about such a concept, as the definition of age, we need to know what stages in our development we go through.

The period of newborns is the first 4 weeks. Breast - from 28 days to 12 months. Early childhood is 1-3 years. Preschoolers - from 3 to 6-7 years. Then come the younger schoolchildren - 6-10, teenagers - 11-18, boys and girls - 16-20 years. The mature age (the first period) occurs in women and men from the age of 20, ends at 35. The second segment of maturity is 35-55 and 35-60, respectively. Elderly people from 55 to 75 are considered. Then the old stage - up to 90 years. Above are the long-livers.

My years are my wealth

Biological age is probably more important than chronological age . After all, this is an objective indicator of how the "motor" and other parts of our "mechanism" work. And their "serviceability" is influenced by both external factors and the presence (or absence) of any pathologies.

Heredity is good or bad - this is perhaps the main thing. But the biological experience in many ways depends on the living conditions. That is why in the second half of their lives, people of one year of birth can differ sharply from each other in strength, tone, even mood. Younger than their passport data, as a rule, those who have a daily life favorable. And they have a positive heredity.

In recent decades, scientists have added a third to these two circumstances. This is self-government. A person's consciousness to some extent affects his body, his condition. And it turns out that these factors also play a role in our health and life expectancy. Heavy conditions of work and life, hard physical work, frequent nerves, stress and overall psychological discomfort do not strengthen, but wear out the body more quickly.

Biological age can be seen immediately. The old man in this respect has obvious violations of the main vital functions, there is a bouquet of diseases and a higher risk in a rather short time to die.

All children grow differently

Since the state of health - this is not the number of years lived, but the age of our body, then the definition of biological age occurs according to how individual organs work.

Let's start with the children. Every boy or girl lives the same stages in development. Yes, their pace is different. They depend on heredity - once, the living conditions - two, the quality of nutrition, ecology, sports - three. And much more.

Because all babies have different biological preschool ages. The determination is made using tests and any measurements.

However, some children outstrip the development of their peers, although they are in exactly the same circumstances. Why? Biologically more mature boy or girl is much easier to cope with their loads - physical and mental. They react less to stresses, microbes, colds.

Specialists determine the age of the child simply. Measure the height and weight, watch the pace of their changes, the state of bones and teeth.

There are also growth jumps. This is when the schoolboy suddenly grew up over the summer. And pre-school children have a half-growth jump. Do you want to know if your heir has passed so important for him? Ask him to reach out with his right hand to his left ear. Only carry it must be above your head. This test will give information about how the nervous system has matured. And how the brain is ready to receive and process new information.

What is this for? This criterion says whether your son or daughter is ready to go to grade 1. Or let him spend another year in kindergarten.

Doctors say: here the graduate of kindergarten was seated at the desk, when he is physiologically not ready for school. What will happen? Bad health consequences and before - a negative impact on the mental state. Before you - the future lagging student.

Parents also need to follow the data of bone age. Give a more accurate definition of the biological age. Analysis - on the x-ray of the hand and wrist.

And the age of the tooth is not less important. Write down when the baby has grown and dairy, and permanent teeth.

Several ways

And how is the biological age of an adult determined? Tests of various complexity are used. But briefly, the essence is as follows.

The first option is the most difficult one. He needs special equipment. Conduct the test only in a well-equipped clinic or even in a diagnostic center.

There are two more methods. Both, of course, are less labor-intensive, but they can not do without special equipment.

But the fourth method is quite simple, and therefore it is used most often. He is called "Methods of determining the age of Voitenko." In any conditions: at home or in a polyclinic, working at home or at the dacha - you can find out "how much" you hit. No special diagnostic device is needed.

Himself a diagnostician

1. Tonometer (on the right hand) three times with an interval of 5 minutes measure pressure. Record the smallest score. The pulse reading is the difference between the first and second.

2. They sighed deeply - and did not breathe! Stopwatch measure three times with a break of no more than five minutes, how long you lasted. Consider the highest value.

3. You stand on your left foot, taking off your shoes. Eyes are closed, arms along the trunk are lowered. No preliminary training can not be done. And so three times. Break - only 5 minutes. Record the longest standing time. Consider the best result of three attempts.

4. Measure your weight. Result also fix.

5. Calculate the self-assessment index of your health. This can be done on one of the medical sites.

There are also various tests. They can be easily found and tested.

Wait a minute, they're shooting you!

The new system, which defines the age of the gait, was developed in Japan. Four thousand people of different ages were examined. Everyone walked twice a line six meters ahead and back. All movements were filmed on camera. As a result, a database was created. In them - models of walking young, old, young. Distinctive features - the length of the step, the stroke of the hands, the tension of the muscles of the back. According to these indicators, the apparatus determines how "young" a person moves.

So, 20-30-year-olds do not move their hands very much, unlike those who are 40-50. The older the man or the woman, the more they hump when walking.

Worth this equipment in the Science Museum of Tokyo. Anyone can come. It has become fashionable to determine the age of yourself and your loved ones.

You can also learn the biological age in the teeth, which is particularly interesting for criminalists. Or by analyzing the voice, the presence of wrinkles. A drop of blood, as they do in Holland.

Supernova Technology

And the original definition of age from the photo. Such a miracle-novelty appeared on the digital market. The program for a few seconds finds out not only the age, but also the sex of the person according to his picture. Even if several people are photographed on it - you will receive information about everyone.

True, there were failures. So, one girl was given age ... 9 years. And the boy was offended, saying that he was a girl. But the blame is both the light and the grimaces of man.

However, despite such mistakes, such a modern and prompt definition of the age of a person becomes very popular.
