A groundbreaking and fascinating investigation into the transformative effects of exercise on the brain, from the bestselling author and renowned psychiatrist John J. Ratey, MD.

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.

This is a brief for exercise as an element of brain fitness. The author is a Harvard Medical School Professor. There is a lot of science here --any more and I would have been lost. The idea is simply this --we are designed to be moving animals. Our brains are controlled by chemicals which must be kept in balance and cells which must be replensished and grow. Vigorous, regular exercise, like a pill we take every morning but wihtout the side effects, helps manage all of this complexity.
