1. In 2001 fit kids scored twice as well on academic tests as their unfit peers.

2. German researchers found that people learn vocabulary words 20 percent faster following exercise than they did before exercise, and that the rate of learning correlated directly with levels of BDNF.

3.Specifically, every fifty minutes of weekly exercise correlated to a 50 percent drop in the odds of being depressed.
