I wonder the same things! I remember when I was a kid we LOVED being active, and the school had us active all the time. I remember we looked forward to running, because the school rewarded you for it. You used to get a little plastic foot that you put on your shoes, and the more you ran, the cooler the available colors were. It was a "collect them all" type of deal. I remember the COOLEST kids in elementary were the kids who had the most feet on their shoes. We used to jump rope and pogo stick, practice running so we could get the most feet. There were special days of the year where the ENTIRE  elementary school would use the cafeteria to have a giant game of four corners or dodgeball. It was awesome.  I cannot fathom that these kids only have PE twice a week.  No wonder all these kids are being diagnosed as ADHD. They're pent up all day.   I wonder  who decided this was a good idea.
