I know for sure that if I was as brittle when I was a kid as I am today I would have died at least twice a week when I was growing up. Falling out of tree-forts and using my brother as a counter weight on a teeter-totter to see how high we could launch each other by jumping from the swing set at the top of the arc and trying to land on the end opposite the one he was standing on are just some of the ways we went about learning how gravity functioned to our detriment

Then there was the chemistry set we shared when I was 9-10 years old had a Bunsen burner, copper sulfate, and REAL Uranium with an asbestos "mat" around the back of it's sealed packaging. (PS, I wonder if the Uranium or the Asbestos is actually the more dangerous of the 2 LOL.) Even the sleds when it snowed enough to blanket the roadways in my neighborhood. Many things growing up provided opportunities to remove ones self from having to grow older, yet somehow I never had a kid in my school/neighborhood killed or seriously injured. I think kids are much less fragile than we tend to consider them. Neither of these 2 videos would have caused anything more than a bruise or 2 that needed Mom to "take care of" it with a quick cleanup, and a kiss.
