Want to know how long do you live? Scientists believe that your own choice is very important


After over 400 million analysis of people's life expectancy showed that the influence of genes at age was significantly lower than the previously calculated coefficient. The starters of the study believe that another factor that has not yet been discussed is wide ranging, writing, without excluding or the value of the living environment.

What is a life expectancy decision maker? Choosing Ogi. When choosing partners and similar partners, we seem to pass on the cultural and genetic characteristics of life expectancy, such as the transfer of property that we own or, or # 39; social and economic status.

"Human genres say a lot about biological processes related to aging, but life legacy is not so significant," said scientist Graham Ruby, who led the study.

By explaining how features travel through generations, scientists determine the need. This measure also shows how the property is transmitted, such as life expectancy, changes over time, and affects genetic and non-genetic differences. The latter could include lifestyle, social-cultural context, unexpected circumstances, etc.

The findings of previous studies show that a person's life expectancy is 15-30%. The legacy is decided, but the authors of the new study using Ancestry, a genetic online source of data, argue that this factor is too high.

"Ancestry was able to carry out a more detailed analysis because we could use a larger dataset. The authors of previous studies did not have such opportunities," said one of the participants in the study group.

In order to analyze the data as close as possible, researchers selected a number of relatives and special attention was paid to 400 million. Nineteenth-century people All had a relationship between parents and children or spouses.

By developing a data-based model, researchers saw unusual and unregistered regularity. It became apparent that the spouse's life is very similar – more than brothers and sisters whose genetic heritage is much more similar.

Yes, of course, I can, because of the fact that the spouse lives in the same environment. However, some data is triggered by another reason.

It was found that brothers (siblings and spouses), as well as the first cousins ​​and cousins ​​of the spouse, although not related to blood, and who also do not live in the same environment, also survive a similar number of years.

Starting to study the lifetime of other spouse's relatives, such as uncle, aunt and cousins ​​and half-siblings of the first line, researchers have noticed the same regime, which contradicts the conclusion that life expectancy on both sides of the family tree is similar.

Therefore, the data, as well as genetics and a common living environment, also showed that there is a third factor that determines the period of life – a partnership of similar persons. This is the case where a fairly large number of options for a partner are similar to a voter.

"The partnership of similar people is important because the features that connect to the partner are factors that determine longevity (or vice versa) , "said Ruby.

It does not in any way mean that people are rewarded with a sixth feeling that allows them to know in advance how many years their partners will live.

However, according to scientists, people are really reluctant to choose their own partners, and this similarity is usually genetic and social, and the factors of the scholars, like the news, are incredible of longevity.

Simply because rich life, for example, leads to longevity, while rich people try to get married with less affluent people, the lives of rich family members are automatically like.

The same is true of genetic property. Therefore, if high people choose high spouses and heights affect life expectancy, they will be able to see the same regularity.

Regarding the importance of similar partnerships, researchers spent 7% on life expectancy. affecting it, half of what was believed to be so far.

Therefore, the longevity of the genes, which is similar, is not as common as we have imagined.
