Given the childhood obesity problem, perhaps schools should also have a social mandate to promote activity and healthful eating, and schools with lousy food and no phys ed would lose federal aid. Let every child stand in class, if they like, I say! Burn more calories that way. And it’s probably better for posture, and the boredom that comes from the monotony staying in one position. Teach while everybody walks! Or runs in place! Combine phys ed with math! Why not? I’m sure some wag with label this program: No Child With a Big Behind.
