  1. As stated by Stanford Medical, It's in fact the SINGLE reason women in this country get to live 10 years more and weigh 42 lbs less than us.

    (And by the way, it has NOTHING to do with genetics or some secret exercise and really, EVERYTHING around "how" they eat.)

    P.S, What I said is "HOW", and not "WHAT"...
