haha... just kidding... But agreed ... Otherwise you'd have kids that are overweight and they wouldn't have any initiative to take a phys ed course... So they probably wouldn't get any more excercise than walking between classes. But! Our school you only need two credits of phys ed... So two year long classes... or whatever. Freshman phy ed is required freshman year... so there's one right there, then when you take the other class or classes it's up to you.
EDIT: Calvin has a point to where they shouldn't be forced to play sports they don't like... but just a physical education class doesn't hurt... Here the freshman phy ed is the same each year... then when your a junior in high school (3rd year) you can chose different things like cycling or bowling.
