I wonder how many people have been put off exercise by PE at school?

PE classes in junior high and high school were a waste of time and a joke...the teachers would take roll, say they were going to the office and come back 5 minutes before the bell rang and tell us to do jumping jacks or some other trivial stuff....this happened in at least 95% of the classes except when they were testing...then the bell would ring, we had 5 minutes to get dressed and get to class....they could have at least let us go outside and walk around the school or track. They kept the fees for towels too.
