Exercise Slows Aging	February 10, 2008
Reviewed by Molly Reams from Archives of Internal Medicine, January 2008, Vol. 168, No.2. A recent study out of King's College London evidenced that people who stay fit are biologically younger, with a reciprocal relationship to time spent exercising per week. The study of 2401 twin volunteers related keeping fit to the aging process. It is believed that a key to the aging process is related to the length of Leukocyte telomeres, which get shorter as humans age. The study found that exercise significantly increased the length of the telomeres, even when controlled for age, weight, smoking, and socioeconomic status. People who exercised vigorously for 3 hours each week had longer telomeres and were biologically nine years younger than people with a sedentary lifestyle. Researchers are not certain why exercise has this effect, but it appears that physical activity defends against the aging effect. kSero's Note: Here at kSero, we routinely prescribe exercise as an essential element in brain fitness for our clients.
