Growing Evidence Links Exercise and Mental Acuity

Can exercise help keep your mind sharp? Researchers increasingly say the answer is yes.

John J. Ratey, a psychiatrist who wrote the book "Spark: The Revolutionary New Science of Exercise and the Brain", says that there is overwhelming evidence that exercise produces large cognitive gains and helps fight dementia.

The Washington Post advises:

“...while the volume of that research grows, the safest course of action for both body and mind appears to be to keep our weight down, follow a regular course of moderate to intense exercise, and stick with it.”
