I used to jump off the roof of the chickenhouse, about 12 feet. Learned how to land without hurting myself (like a paratrooper’s training)
Good thing my mom didn’t see me doing it.
What I really miss now at my age in 70’s is the complete lack of fear of heights I had in my early teen years. Then I would climb onto steep metal roofs 4 story’s high to capture a runaway kite. There was absolute lack of fear because I am guessing I had supreme confidence in my balance and athletic ability. Now I get sweaty palms looking down from my 3rd floor balcony with 36” high strong guard rails!
