Well. of course they should. Fat people, skinny people, old people, liberals, conservatives, Catholics, Mormons, Muslims, Jews…… I suspect most of the adult population would be happier and healthier if they had a little more sex.
But according to a new study, sex, just like tennis, running, boxing, and most slightly strenuous to pulse pounding activities, would be much safer if you train for it and get in reasonable shape. According to a research study from Tufts University, out-of-shape people who engage in sexual activity increase their risk of a heart attack during sex by 2.7 times. And nothing ruins a romantic evening more than a heart attack! (Shoveling snow is even more dangerous – and if you have the option of sex or shoveling snow I recommend the former.)
So lose a little weight and increase your endurance, and sex might not only be safer, but I suspect it will also lead to more opportunity to have sex.
