It's time to change your thinking that plastic surgery or expensive face creams are the only option to help you look years younger. A recent study from King's College in London, published in the Archives of Internal Medicine, tested more than 2,400 British twins and discovered a new benefit of moving the body. Exercise appears to slow the "shriveling of the protective tips on bundles of genes inside cells, perhaps keeping frailty at bay." Translation: physical activity actually changes your cells on a molecular level, making you look up to 9 years younger.

Considering that laughter also produces natural endorphins, those "feel good" brain chemicals that lower your blood pressure, decrease your stress and improve your mood, you have nothing to lose, except maybe a little weight and stress, right? And if that doesn't sound like a bargain, at least you can laugh your way through a daily square of chocolate and even the score.
