The research in Sweden ended with a verdict of scientists about what lies at the heart of a long life for a person - and their opinion refutes many theories on this matter. Can I live longer with my own efforts? The results of the fundamental work that answers the question.
It is believed that the life expectancy can be significantly increased if you take certain actions for this - for example, adhere to a healthy diet or exercise. The authors of the new study concluded: although such measures do improve the quality of life of a person, its aging and duration of existence in the world is a consequence of random effects and environmental factors.
Specialists observed the twins living in Sweden to determine how important the role of genes and external circumstances in the matter of longevity. They gathered a group of 385 people, whose average age was 69 years. For 20 years, blood samples were taken from the subjects for genetic studies. As a result, specialists were able to observe how DNA changes with aging.
Based on the analysis, scientists concluded that one of the determining factors of human aging is the DNA methylation - the process of modifying DNA molecules, which are associated with adverse events in the body (for example, the activity of cells that prevent atherosclerosis is suppressed). But, after studying a lot of methylation options revealed during the study, the authors of the work became convinced: none of them was correlated with heredity.
Even in twins, as it turned out, DNA methylation as the age occurred with increasing difference.
Thus, experts ascertained, the life expectancy of a person depends not so much on heredity as on the influence of the environment. The final result of such an effect can not be predicted, although this does not negate the need to follow healthy guidelines, scientists noted.. People who neglect them, are characterized by a lower quality of life sundaynews. info.
