We all did stupid things, but that’s how you learn.
I one jumped from a tree fort 20 feet high out to a branch, the branch snapped and I fell to the ground landing on my neck and right shoulder, fortunately didn’t do any serious damage. To this day my brother reminds me I should be dead or paralyzed.
Once my 10 speed front tire got caught in railroad tracks as I was riding as fast as I could and down I went on my head, no helmet of course.
Once I raced a guy down a steep gravel quarry, got a broken arm.
Lots more misadventures, as I am sure most had, but no way would I trade times with today’s kids.
I once tried to bend a nail in a board by stomping on it. The whole city probably heard a kid screaming with a board nailed to the sole of his foot. My dad grabbed me, and a stranger ran up, pulled out some pliers and pulled the nail out of the sole of my foot. I limped for several weeks and learned my lesson.
Then there was the time I missed getting my left eye put out with a home made arrow when it hit 1/2 inch low.
Did I mention playing with matches and setting the hay stack on fire?
