Scientists have found an age line, after which aging stops

Demographer Elizabeth Barbie from the University of Rome, Sapienza, studied the reports of the Italian National Institute of Statistics in search of evidence of the theory of the existence of a “mortality plateau” for humans. This phenomenon is known and proven for the simplest creatures, fruit flies and nematodes – but in humans? Italian municipalities are very zealous in controlling births and deaths, which gives the field for research.

All living beings grow old, become more decrepit and morbid, in different ways. But there is a general rule – the older the individual, the higher the risk of injury or death. For example, for a 50-year-old man the chance to break a thigh is three times higher than for a 30-year-old. After 60 years, the probability of death is doubled every 8 years, and the chances of living at least a year after the onset of the century are only 40%.

The death plateau is the boundary, after which all the probabilities are erased, become the same. For a person, it is calculated as 105 years, after which the probability of death due to “old age” never changes. Health does not increase, it is a fact, but it also ceases to decrease, it remains at a certain small level, when the impact of an accidental factor can cause death.

Elisabetta Barbie collected data on 3836 long-livers of Italy, who indirectly confirmed the theory – after 105 years of sores is not added or they cease to matter. This is explained by the fact that until this age only the strongest individuals survive, with a special genotype, in which there are no pathologies that can cause illness and death in earlier years. If this is so, then we can find the key to longevity by studying the genes of these people – even if we do not yet know how to transfer useful anomalies to newborns without violating the numerous legal and moral norms.
