Troubled by wrinkles around your eyes? Worried that your skin is sagging, or those gray hairs are making you look your age? So have sex. Making love three times a week can make you look 10 years younger, claims a Scottish researcher. The young-looking participants had sex an average of three times a week, Weeks says. By comparison, a group of men and women in the same age bracket and from similar neighborhoods reported having sex an average of twice a week, he says. More frequent sex -- more than three times a week -- didn't seem to produce any added benefits, Weeks says.
