I played sports during high school but, during the off season, I was part of a regular PE class. The majority of the students would run the mandated 3 laps or some such and then either sit around talking the rest of class or ditch and go smoke weed.
Regular PE classes at my school were a waste of not just the student's time but, the school's resources. Had they taken the money wasted on herding kids around a track for a few hours and spent it on healthy replacements for greasy pizza, nacho cheese fries, and coca-cola, maybe I wouldn't have had to lose 40 pounds in the last 12 months.
Looking back, it's a microcosm of the United States' disease care system...
Eat high fat/high glycemic index/generally unhealthy foods during lunch and then work as much as you can off during PE an hour or so later because, if you don't, you'll get fat.
Eat high fat/high glycemic index/generally unhealthy foods for breakfast, lunch, and dinner and then refill your prescription for your cholesterol/diabetes/high blood pressure because, if you don't take it, you'll die early.
But, I digress. I agree that the resources used for "physical education" in public schools would be much better suited elsewhere. As a musician, I would definitely support directing the funds to a music program. Look on the bright side: all the kids that ditched PE to get stoned would... probably still do it... but, I bet you they'd come back to listen to/play music. :P
