Did you know you can beat stress, lift your mood, fight memory loss, sharpen your intellect, and function better than ever simply by elevating your heart rate and breaking a sweat? The evidence is incontrovertible: aerobic exercise physically remodels our brains for peak performance.

In SPARK, John Ratey, MD embarks upon a fascinating journey through the mind-body connection, illustrating that exercise is truly our best defense against everything from depression to ADD to addiction to menopause to Alzheimer's. Filled with amazing case studies (such as the revolutionary fitness program in Naperville, Illinois, that has put the local school district of 19,000 kids first in the world of science test scores), SPARK is the first book to explore comprehensively the connection between exercise and the brain. It will change forever the way you think about your morning run.
