New York Times Phys Ed columnist Gretchen Reynolds discusses a large-scale Cardia study, which shows that the more physically active you are at age 25, the better your thinking tends to be when you reach middle age. The findings also suggest that even if you neglected to exercise when you were young, if can start now you can still improve the health of your brain. She wrote about it in her article "Early Fitness Can Improve the Middle-Age Brain."
