In addition, men who did not refuse sex even in old age, the risk of heart attack or stroke were almost two times higher than the rest.
Scientists believe that all the matter in excessive load on the cardiovascular system during pleasure, as well as the use of drugs to improve sexual function.
But with women the situation was different. Lovely ladies who had sex after retirement, much less experienced hypertension.
