In a separate study of ten rowers at Harvard, Frisch found that active women produce a less potent form of estrogen than their sedentary counterparts. Result: breast and uterine tumors that depend on the hormone cannot develop as easily. In addition, athletes lack excess body fat, which can predispose people to diabetes...
