A new, first-ever study from Johns Hopkins University revealed the incredible healthcare costs that societies would save if all the children who are currently inactive (a skyrocketing number) exercised just an hour a day. Using complex computer simulations, the researchers found that the U.S. alone would save $120 billion annually. This is a mounting global problem, as research shows that in Europe and the U.S., physical activity tends to peak at age seven and plummets throughout adolescence.
