The younger face is easier to live

A study in Denmark shows the secret of longevity that appears right on our faces.

Professor Kaare Christensen, an expert at the University of Southern Denmark, believes that the sense of community about an individual's age is the person's health index. For example, people who are judged to be younger than age will have better health than older people.

To test this claim, Christensen and his colleagues tracked 1,826 twins in Denmark since 2001. According to the Daily Mail, all twins are aged 70 or older at the time of the study. Scientists check their physical condition, cognitive ability, and take pictures of them.

The team recruited hundreds of volunteers and divided them into three groups to assess the age of the tools through photos. Of course, they did not show the photos of two people in a couple to the volunteers on the same day. The results of the assessment of volunteers' ages were carefully recorded.

During the next 7 years scientists continuously updated information about elderly people who died. By 2009 they aggregated data on twins and compared the results of the volunteers' age estimates. The team found that the majority of lost instruments were rated older than their actual age. This trend has not changed after experts removed factors related to each person's age, gender and living environment. If a person in the twins is assessed to be younger, the likelihood of them dying after the other person will be higher.

According to Daily Mail, Professor Christensen also investigated whether the person's life is related to telomere - the end of the chromosomes - or not. Telomere is located at the end of the chromosome and is responsible for protecting DNA strands from inflammation and preventing aging. The longer telomere is, the younger the person is compared to the age and healthier.

"Studies for telomeres are complex, but they only show that telomeres do not have much impact on life. Instead of looking at telomeres, we just need to look at a person's face to guess the chance of living a long time , " Christensen said. .
