I hated gym class in high school—dodgeball, softball, the dreaded gymnastics equipment. Turns out, I was just born too early. Nowadays, teenagers in West Virginia can dance the gym class away with Dance Dance Revolution (DDR). Further west in Colorado, teenagers can skateboard during gym period. In Minneapolis, you can take gym online.
The comprehensive number for physical fitness for young people twelve to twenty is 613.7043; add T1—071 Education and you have the number for high school gym class, 613.7043071. The number for DDR is 793.3 Social, folk, national dancing; the number for skateboarding is 796.22.
