Long Life

A 1997 study from Australia found that men who had sex frequently – 2 times a week or more – were 50 percent less likely to die from any cause than men who had it less than once a month. This result stood up even after researchers took into account coronary heart disease, social class, smoking, and blood pressure. Beware, though, because infidelity seems to be linked with an increased risk of cardiovascular disease and, while sudden death by sex is rare, when it does happen, there's a 75 percent chance the deceased was having an extramarital affair.
