American scientists from Columbia University (New York) told that a person's life expectancy depends on his desire to live.
According to experts, the lust for life is the main factor affecting its duration. But the gender of a person, his success in various matters, social status do not have such a big impact.
As the scientists said, they studied data on several thousand people of different sex, age, profession, social status. The people who took part in the study worked in various fields. It turned out that all these factors do not affect life expectancy as much as the correct psychological attitude.
More, as it turned out, among the long-livers are people who were not afraid of old age and knew what they would do after retirement. That is why, scientists believe, there are representatives of all classes among centenarians, and not just the rich and successful.
Therefore, experts advise not to lose heart to people approaching retirement age, but to strive to find an interesting occupation, even in old age.
