Very interesting. Your high school gym class looked very different than mine. Mine had walls lined with girls, sitting and chatting. There were a handful of boys playing some basketball. A kid off by himself somewhere sleeping. Maybe a boyfriend and girlfriend walking the perimeter of the court. There was a teacher. I’m SURE of it. But I don’t remember who mine was… even if it was a male or female. There certainly wasn’t any teaching at all going on. I used to play basketball, mostly by myself, and get all sweaty. The girls thought it was gross, but I thought they were gross, so it worked out fine.
I’m not sure when it became such a drag having to go to PE… in middle school I remember kids being a lot more into it, but I always felt like it was a great introduction to what physical activity would become for many of them for the rest of their lives… an item under the “I should” label. Or “I have to”. We really had different experiences. I remember wishing that the teacher could make it more fun for everyone else. Everyone looked so tortured. I, in my early hermit ways, was thrilled to have a ball and basket to myself. 
My pleasure. I hope your next adventure is as much “feels good” as you need to make you want to do it again sometime. That’s what it’s for.
And thank you for the opportunity to get preachy. It’s been too long.
