Longevity depends on genes and lifestyle

Longevity still is not just human genes. A study involving 400 million people showed that DNA almost has no effect on how long we live.

For a long time science tries to answer the question about what makes a person a survivor. There is a view that the ability to live up to 100 years is determined by two sets of factors. The first is related to genes and lifestyle. And now a study involving more than 400 million people has shown that genetics in this matter has no decisive value. In other words, some characteristic changes in the DNA of almost not have any impact on the life expectancy of people.

Magicforum recalls that DNA determines many of the characteristics of our health, and genetic analysis with every year becoming better and more available to a wider population. Many believe that with the help of this analysis it will be possible to predict health and what diseases we will give the next generation. However, life expectancy is determined in most cases by external factors like lifestyle and nutrition, and lack of bad habits like Smoking and alcohol abuse. Also of great importance are social factors, including material wealth. Their inclusion allows a greater degree of reliability to predict the average duration of human life.

Although in some families there are centenarians for several generations, hardly on the basis of this we can hope to live a long time, the study showed. Approximately 7% of longevity is determined by genetics. People are animals, and biological we want to live as long as possible. It’s human nature to observe the centenarians and try to unravel their secrets. It is engaged in gerontology. Many experts believe that genes matter. But is it? Frenchwoman Jeanne calment, who lived 122 years, had long-lived parents, but her children did not inherit these genes. The daughter died at age 35 from pneumonia, son of Frederick died in ‘ 73, his grandson – in 36, and husband of Jeanne – 74. (READ MORE)
