Hardworking people live longer

They found that marriage lengthens the life of men but not women, while social ties promote longevity in both sexes.

In addition, research has shown that hard workers live longer and healthier than frivolous and idle people.

"If you want to improve your health, you should not give in to the flow of events, but engage in meaningful and productive activities," says Howard Friedman, a psychologist at the University of California.

The results of recent research have shown that social people live longer.

Thus, individuals surrounded by family members and friends have a 50 percent greater chance of outliving people who do not have a rich social life.
