Exercise and the Brain

 
In his fascinating book, Spark, Dr. John Ratey, clinical associate professor of psychiatry at Harvard Medical School says “What’s good for the body is good for the brain.” Ratey believes that when people realize how lifestyle can improve their health span—living better, not just longer—they will be more inclined to stay active. And knowing exercise is as important for the brain as it is for the heart, helps with commitment.

What’s easier than walking? It’s accessible to almost everyone. It’s safe and doesn’t require practice. There are no gym fees. The health benefits are significant.
