"In Finland, where substantial physical activity is part of the school day, rates of ADHD are also very low. Meanwhile, in the U.S. children are asked to sit still for the majority of the day. Elementary school students often get only 15-20 minutes of recess a day, a far cry from the 60-90 minutes their parents had. Coincidentally, ADHD rates in the U.S. have gone up over the last 15 years. "
