The Centers for Disease Control (CDC) surveyed 5,000 students ranging from kindergarten to fifth grade and found that girls who got from 70 to 300 min. of physical education per week scored consistently higher on standardized tests. More exercise also translated into increased classroom participation and concentration skills...

In light of such...
