A study by Germany's Max Planck Institute has found that men who marry younger women live longer than their counterparts who marry older females.
The study also found that men who married older women were more likely to die early. The researchers said that the findings may have come about as only the fittest of men are able to attract younger females even if they are aged. "Another theory is that a younger woman will care for a man better and therefore he will live longer," said institute spokesman Sven Drefahl.
The study found that men may reduce their risk of premature death by 11% if they marry women seven to nine years younger than them. Men who marry women between 15 and 17 years younger than themselves reduce their risk of premature death by 20%.
In contrast, men who married women who were seven to nine years older than them had a 20% risk of early death.
