English researchers surveyed the sexual frequency of 918 reasonably healthy male residents of the Welsh village, Caerphilly, who were 45 to 59 when the study began (1979-83). A decade later, they checked back with the men, when they were aged 55 to 69. Of the group studied, 150 had died—67 from heart attack and 83 from other causes. The researchers then correlated the men’s sexual frequency as reported in the original survey with their death or survival 10 years later. Compared with men who had had sex just once a month, those who reported having it twice a week had only half the death rate. For the entire group, as an individual's sexual frequency increased, his risk of death decreased.
