More on Gym.
I went to a large (2400 students) High School. One of the things I did like about gym was swimming...the high school had a superb pool.
I liked swimming, but I didn't like certain aspects of it. The girls had to wear a regulation red tank suit with name embroidered on the back. And they always checked to make sure you had taken a proper shower: you'd have to soap up, be inspected, then rinse and THEN get into your suit. ARGH.
Oh well, better that than the regulations for the boys. They had to swim sans suit, supposedly for health reasons. (According to google that's not so strange. See here or here.)
