One of the two bones I broke as a kid had a similar cause. That might sound like an endorsement of your claim, except first that it gave me powerfully to understand the value of forethought on the subject of not being a damn fool, and second that the other broken bone resulted from jumping up and down on an ordinary floor - not even jumping
off anything. Are floors a problem?
I have a scar at the base of each thumb. One came from carelessness with the Boy Scout folder whose purchase price I'd years earlier worked hard to earn. It wasn't the first time I'd hurt myself through carelessness with that knife, either. It was the last, though, with any. Are pocketknives a problem?
The other scar I earned through waving a stick around. It wasn't really an instance of culpable carelessness on my part, in that if the stick hadn't had a twig stump where it did, or had I held it differently, it wouldn't have gouged me. I found a lesson there about unintended consequences that's served me well in life. Are sticks a problem?
In rough terms, I spent half my pre-adolescent childhood running around barefoot climbing trees and derelict farm equipment, and the other half indoors reading and playing NES games and writing Applesoft BASIC. I found both enjoyable, and a worthwhile way to spend time. I would not have attempted to replace either with the other. To make the attempt would have struck me as arrant foolishness, even at such a callow age, and I cannot say the idea seems any more sensible from a perspective more heavily weighted with years.
