Sex Can Kill
Researchers from Tufts University compiled data from 14 studies which explored the link between sex and heart attacks. They were able to conclude a person is 2.7 times more likely to have a heart attack during sex, or one to two hours after the love making, than they are during normal activities.
According to the study, exercising regularly can reduce the correlation between sex and heart attacks by 30 percent. More informal research also suggests regular exercise will increase the likelihood that other people will want to have sex with you.
