How about letting kids in elementary school have recess???
Not an organized gym class - a plain old, run around like crazy, yell, chase the other kids, run away from the other kids, swing from the monkey bars, slide down the big slide recess.
But no, we have too much to teach kids, so they have sit still for six hours. And people wonder why obesity and ADD and ADHD are so prevalent. Oops, I forgot. I'm not a member of the NEA, so I don't know anything about brainwashing, whoops, make that educating children.
