Exercise - It Does a Cell Good

In the study, conducted at King's College in London, 1,200 pairs of British twins were tested. Just one hundred minutes of activity a week made cells of active twins look five to six years younger than their couch potato counterparts. With three hours of exercise, the cells looked nine years younger.

Young-looking cells may not seem much to crow about, but scientists have long theorized the younger your cells appear under a microscope, the younger you look on the outside. As cells age, they divide. Over time, a cell loses its ability to divide and dies, causing aging symptoms like wrinkles, reduced organ function, and poor eyesight. So while exercise helps you feel better and keeps you healthy, it may also help you look younger.

Excuse me while my cells and I slip on our running shoes.
