The thing that struck me most in that first article is that kids aren't moving like they used to, and that is so very true! When I was in grade and middle school, we had PE every single day. High school, we had it 3 days a week, then Health the other two our freshman year only. After that, we were on our own for PE - our only options were weight training or signing up for one of the athletic teams.

My youngest kid has PE once a week. Once. Recess is routinely canceled for bad weather. What the actual F? *headdesk*

And yeah, he's been diagnosed with ADHD and he is medicated for it. It was that or risk having him kicked out of school in kindergarten.
