Exercise Already!

Via Scientific American, another small piece in the weight of evidence for the health benefits of exercise: "Our study shows that greater physical activity in your 30's, 40's, and 50's has beneficial effects well into the future ... Our results imply that a physically active lifestyle throughout the life course can not only lead to longer life expectancy, but can also help maintain our ability to walk and quality of life for a longer period of time in older adulthood ... seniors who reported engaging in vigorous physical activity during their earlier years scored nearly one point higher on a battery of tests evaluating their physical performance, including their walking and chair-rise speeds, than did those who reported the lowest level of physical activity. In a previous study, researchers found that older adults who experienced a one-point decline on the tests had an 80 percent increased risk of death." Taking better care of your health today means an increased chance of living to benefit from the working anti-aging medicine of tomorrow.
