It turns out that people who live long have certain signs. And they are related to the physiological characteristics of their body.

In China, women live longer than men. And experts have found the answer why. According to one recent study, this may be due to the characteristics of the male Y chromosome.

The female X chromosome is better able to repair itself and is able to slow down aging better than the male one.

In addition, data from biological behavior studies show that men drink more alcohol, smoke more, and are more likely to be obese.

Moreover, compared to women, more men are fond of extreme sports.

As for the signs of long-livers, they often have the following features.

This is a strong grip (and therefore strong muscles), a slow heart rate (and this is typical of all mammals that live long), a large lung capacity, and a developed sense of balance.
