MOSCOW, Oct 5 -. RIA Novosti Further improvement of medicine will not increase the average life expectancy is infinite - limit a person's age, most likely, is rising sharply around 100 years old, at which mortality, regardless of any external factors, say researchers in an article published in the journal of Nature .
The typical duration of a human life is not some constant value - before the birth of civilization, it ranged from 20 to 30 years, and then rose steadily with the development of science and medicine. Today people live more than 60 years in most countries in the world, and more than 80 years - in Japan and other developed countries with a high quality of life and first-class medicine.
Yang Vijgen (Jan Vijg) and his colleagues at the University of New York (USA), as well as many other scientists have reflected on how long you can last the process, and whether there is a maximum age at which people start to inevitably die, despite all the advances in medicine and technology.
How much rope does not curl ...
To test whether this is actually Vijgen and his colleagues came up with the original method of analysis of mortality data, which were collected over the past hundred years. They were interested not in fact the number of deaths of people at a certain age, and that where there is the most significant decline in the number of dead people when comparing data earlier and later years.
If there is no limit of life, this "hump survival," as scientists call it, will smoothly and continuously move towards a more advanced age. If it exists, the "hump" will stop at a certain point, and will not move forward.
Their analysis showed that the "hump survival" is gradually moving towards a more mature years until mid-1980, after which it ceased to grow. In turn, the maximum age of people who die in a given year, is not only not increased, but has fallen markedly in the last 20 years after the death of the oldest inhabitant of the planet, Jeanne Calment, who died in 1997 aged 122 years.
... Anyway will end
Such a low probability, as noted Vijgen and his colleagues said that the limit of human life exists and that it is approximately equal, as shown by their calculations, a hundred years. You can say that humanity has reached its limit, step over that it alone can not without artificial intervention in the vital activity.
"Further progress in the fight against diseases, are likely to increase the average life expectancy, but the maximum length of a person's life. It is possible that future breakthroughs in medicine prolong human life beyond these limits, but they will have to suppress or overcome the influence of the set of genetic factors, measure our life on Earth may have that the resources that we now spend on life extension, should be used for the extension of health -. how long older people remain in good health, "- explains Vijgen.
Does this mean that there is a genetic program of aging programmed evolution? The authors point out that such an outcome is unlikely, as our ancestors, and all the other animals have died and are dying much earlier than old age begins. This makes such a "clockwork" meaningless, the scientists conclude.
