Someone asked a substitute teacher if she would make that trade, and she said she wouldn’t, not unless she could retain what she knew now. So, buy a renewed youth? Sure. But do 22 again as a 22 year old? Nope. Now that I’m “over the hill”, I see what she meant. Being 44 is similar to the difference between 11 and 22; not as drastic, but the stuff I understand about life I would not even be able to communicate to 22 year old me. Definitely would not want to relive my 20s. “Life starts at 40” is not just cope, there’s some truth in there, too.
