Dating younger men can reduce a woman's life expectancy, says a research.
The findings of the research show that having a partner seven years younger increases a woman's chances of dying earlier by 20 percent, reports telegraph.co.uk.
"The greater the age difference, the lower the wife's life expectancy. The best choice for a woman is to marry a man of exactly the same age," said Sven Drefahl, who carried out the research.
The findings also revealed that men who marry younger women live longer.
"The mortality risk of a husband who is seven to nine years older than his wife is reduced by eleven percent compared to couples where both partners are the same age," according to the report.
The study used statistics on two million Danish couples.
