Adding a plug for Ratey's book "Spark" (https://www.amazon.com/Spark-Revolutionary-Science-Exercise-Brain/dp/0316113514/ https://www.amazon.com/Spark-Revolutionary-Science-Exercise-...) which is a pretty good lay introduction to a lot of the research on cognition and exercise as well as exercise's role in ameliorating depression, anxiety, stress response, and some neurological deficits. Recommended by my physician. Turns out the wonder drug we were looking for might have been "take a lap".
