In high school gym, we played "slap tag". You'd start in the basketball circle. You had to hop on one foot, and try to touch somebody. Then they were "it."
If your other foot touched the floor before you touched someone, you could run back to the circle, but other classmates could slap you with an open hand until you found haven in the circle. If you successfully touched another, you would give them that first hard slap while they tried to make it back.
We also swam in the school pool in the nude In hs - 2 days' gym, 2 days' swimming. hTe swim coach would have the non-swimmers line up at the deep end, and shove this or that one into the drink - fished them out with a bamboo pole. Everybody learned to swim.
Can you imagine today's outrage over that, and slap tag these days? Aya Carumba!
Occasionally, if weather permitted, we were herded outside and had to run around the track for a non-stop half hour. Few kids were fat back then. A typical gym session was 5 minutes of running around Indian clubs, 5 minutes of squat thrusts, 5 on chin-ups, 5 on push-ups, 5 on jumping jacks and 5 climbing the poles or the ropes. Occasionally, the games. Then we were herded into the shower so we wouldn't smell.
We were fit. We were forced to be fit. Which was good.
