According to some scientists, in ancient times the average life expectancy did not exceed 21 years, in the Middle Ages it reached only 33. Of course, not everyone left this world at such a young age..

Even after millennia by the end of the XIX century, the overall life expectancy increased slightly. And suddenly, in just one century, the average curve dashed up, reaching today in developed countries (especially in Scandinavia) unprecedented levels: 68, 70, 72 and even 83 years for women in the country of the Rising Sun.

The sharp reduction in the birth rate and infant mortality, which traditionally “underestimated” the statistical indicators, played a significant role in the increase in terms.. And, nevertheless, scientists are unanimous: there are all signs of a landmark change in a person’s biological age.. What contributed to a decisive offensive to death, and why used to be older people faster? Scientists respond differently.

PHYSIOLOGISTS are sure that most of the people were getting old and went to the grave before the deadline, bursting out from overworking physical labor. The strengths of this world, on the contrary, are often prematurely decrepit due to a sedentary, idle lifestyle. Today it has been experimentally proven that both hypokinesia and limiting physical activity lead to a significant reduction in life expectancy.. The beneficial effect on the body has only a natural alternation of work and rest..

MEDICATIONS believe that in past centuries, people quickly grew old and died due to diseases, epidemics that they could not cope with: plague, smallpox, cholera, influenza, tuberculosis cut short millions of lives in their heyday. In addition, women who did not have a clue about contraception, gave birth as much as "God will send", wearing their bodies to the limit and turning into 35-40 years in pure old women.

PSYCHOLOGISTS believe that the rapid development of industry, science, culture, education, the conquest of democratic freedoms have fundamentally turned a person’s perception of himself and his creative abilities. It is this emotionally positive attitude that seems to “undermine” our “biological clock”.

COSMETOLOGISTS believe that in the past there was almost no culture of care for their body and face, which, without affection and love, faded very quickly, becoming like a baked apple. In addition, the recipes of many miraculous anti-aging creams and ointments were invented only in the middle of the XX century.

ETHNOGRAPHS and ANTHROPOLOGISES see the cause of early aging in the centuries-old territorial isolation of the population, when everyone knew each other and married each other, which led to the accumulation of negative properties in the genes. Today, people often marry not only from different places, but also from different nationalities, thus giving an impetus to genetic renewal and early maturation of the body..

It is known that acceleration is a problem of the last 30-40 years.. But will it entail premature old age and death? The statistics refuted the fears, revealing that, along with the earlier development of the body of children and adolescents, menopausal changes occur later in adults, the working capacity lasts longer, the actual life expectancy is higher. If, say, at the end of the XIX - beginning of the XX centuries. menopause in urban women was observed in 43-45 years, but now it is on average in 48-50 years. Although there are notable exceptions..

Probably, all these and other reasons, taken together, allowed scientists to come to the conclusion that today “we can grow up to one hundred years without old age”. Proof of this - successful experiments to extend the life of animals several times. But if civilization doesn’t put a “bomb” on itself - an ecological one that can change the human genotype? One hundred years for history is no time. What will our “biological clock” show tomorrow? 150 years old? 200? Or ... will the "plant" end? The exact answer science can not yet give.
