I just don't get it?

I try very hard not to get on my soapbox, but sometimes I just can't help it. One thing that always gets me extremely fired up is hearing about kids and their lack of activity and parents complaining about the time their kids play video games. Uh, is it just me or is there an obvious solution? TAKE THE THINGS AWAY, kick their little butts outside and play. More so, show them how much fun it can be to be active and join them. Sometimes this can be hard depending on schedules, but if you can't get out, throw on the music and dance! Have a little fun.
Now, here's another thing that really annoys me. Every time you turn on the tv, pick up a magazine or newspaper, you hear/read about obesity, especially children's obesity. Here's the question I have. If there is such a concern about activity levels, why in the world are they getting rid of PE in schools? This is an incredibly easy way to get children out and make them active. And PE teachers (the good ones anyway) know games and activities that ALL children can do so that there is no one left out. PE is an awesome way to get children moving, help them to get rid of the excess energy to allow better focus, and teach them life long habits. I know I know, there are horrible PE teachers out there who make PE a miserable experience. This is where you as parents come in and help. You can complain to the school for a better PE teacher or simply be a good example of this. And my honest opinion is that an activity class should be required all throughout school--dance, weight training, martial arts, yoga...whatever....I know academics are important but there is a lot to be said for a healthier population. Okay, I am off my soap box now.
Here's the question I have--for those with school age children, what is the PE situation for them? Once a week, twice a week, daily, a block on, then off for weeks??? I am very curious to see what has happened to it.
