"Physical education" would be hilarious if it weren't sad. It's a pretty impressive feat that it managed to simultaneously:

- make me spend quite a lot of time on something exercise-related (since it was "opposite shift" of regular school classes)

- had me do next to zero actual exercise

- teach me literally nothing about how exercise or training works

- make me hate everything related to exercise for quite a few years

Worse than a waste of time, it was actively harmful.
