Everyone thinks sex is so cool. Well I have news for you, sluts: Your risk of heart failure is more than doubled during occasional sex. Sex doesn't seem so "sexy" now, does it?

Researchers who reviewed previous studies on heart attacks found that "episodic activity," especially among unhealthy people, can trigger a heart attack. Sex, specifically, can raise the risk by as much as 2.7 times. The good news? Regular "physical activity" [wink] offsets the risk by some 45 percent every time it's undertaken in a given week. So now you have a choice: Have sex, constantly, or never have sex at all. Or, have sex once in a while, and die of a heart attack.
