Scientists have learned to predict life expectancy

Ученые научились предсказывать продолжительность жизниChances to live to old age is higher among women who gave birth to the last child 33 years later

Researchers found that the telomere length in chromosomes can predict life expectancy, and the ability to bear children at a later age.

Called telomeres end parts of chromosomes. They protect the vital DNA in the process of doubling, preventing the loss of nucleic chains. With age, telomere length decreases. Some experts believe that if you find a way to extend the end portions, it will allow to increase life expectancy.

The researchers used data study Long Life Family Study, which showed that the chances of surviving to old age is higher among women who gave birth to the last child 33 years later than those that got them to 29. The researchers decided to find out what factors are associated with the rate of aging and lifespan, as well as the ability to bear children at a later age.

It was found that among women who had children later 33 years, there were more of those whose chromosomes contain long telomeres. Given the demonstrated relationship between age of child birth with life expectancy, the researchers came to the conclusion that the telomere length can predict the chances of a healthy and slow aging.

However, the researchers caution that the age of childbearing may also influence social and personal factors that are irrelevant to the telomeres.
