15 Shocking Facts About Cougar Couples

Demi Moore and Ashton Kutcher
Buzz, Love

There are statistical reasons for the Demi Moore and Ashton Kutcher split.

Amid rumors that Ashton Kutcher, 33, and Demi Moore, 48, have split after six years of marriage, May-December relationships still keep everyone guessing: Who chose whom? And how long will it last once buttocks sag and double chins set in? Anneli Rufus finds 15 statistics on couples far apart in age, from mortality risks to gay men's preference for older partners:

1. Women who marry men seven to nine years their junior have a 20 percent higher mortality risk than women who marry men their own age.

Cougarship could cost you your life, according to the study that yielded this stat. "The probability of a woman marrying a much younger man rises significantly as women get older," says psychotherapist Mira Kirshenbaum, author of I Love You But I Don't Trust You and Too Good to Leave, Too Bad to Stay. "Twenty-four-year-old women don't marry 15-year-old boys. The higher mortality rate may come from the fact that the women in this group are just older."

2. Men whose wives are seven to nine years younger than they are have an 11 percent lower mortality risk than men with same-age wives.

And men who are between 15 and 17 years older than their wives have a 4 percent lower mortality rate than men with same-age partners. "The younger the wife is compared to her spouse, the lower the mortality in the husband, and vice versa," writes the lead author of the study that yielded this statistic.
