Men will live longer if they marry young wives.

The study was conducted by experts at the Max Planck Institute for Demography in Rostock, Germany. After the experts looked at the life expectancy of all Danish men between 1990 and 2005, they found that couples with older husbands and younger wives hadlonger life expectancy than normal people.

Research shows that men who marry women 7-9 years younger have a higher average life expectancy.

Why does marrying a young wife help men live longer?

The first hypothesis is that the increase in life expectancy is the result of natural selection. Many young women tend to choose older partners to live with. These people often have calm personalities, good ability to take care of themselves and those around them, healthy bodies, and therefore increased life expectancy.

The second hypothesis suggests that most men with wives 7-9 years younger than them often have a rich life. With abundant finances, this group of men live a more comfortable and fulfilling life than the average person, do not have to worry about money, have access to the best entertainment and medical services,... this helps to effectively prolong life.

The final hypothesis is proposed by Sven Drefahl of the Max Planck Institute. He believes that a young woman will take better care of her man when he is sick. In addition, the psychology of men in old age is also more positive if they have a younger partner.

What about women?

Experts say that this has absolutely no effect on women, even if they marry someone 7-9 years older or younger, the risk of death will increase by 20%. If the age difference is 15-17 years, this number will increase to 30%. Living with someone too young or too old can easily cause women to experience prolonged stress, the main cause of early death.
