I remember PE classes.... 55 minute class took 20 minutes to dress and undress, another 10-15 to line up for roll call, not leaving much time to do anything productive, kids rushed to class smelling like goats all day, straight to the vending machine.
Of course now we have all the problems of not offending others because they are fat, gay or disabled. It's a personal issue not a government issue. Blame gamenever ends with these liberals
I remember PE courses as being 5-10 minutes of exercise followed by whatever team sport was relevant for the season.
The team sport aspect was pretty useless since the kids who needed the physical conditioning the most gravitated to the sidelines and didn't do much of anything.
My PE class was almost the same -- we only had team sports like softball, and I being the short fat kid, was picked last, if at all. So I derived very little physical activity from PE.
I'm fat because I have been irresponsible. The same applies to just about every other fat person. In the case of the children, you can rest some of the blame perhaps on the parents not providing the right food or encouraging their children to exercise. But no, being fat is not a school problem, not a societal problem, not a government problem.
