I knew a kid who was constantly getting concussions. Thing was, he was doing stupid stuff. Don’t know which came first, the concussion or the wild behavior. A bike accident nearly scalped him. Last time I saw him, he was hanging off a balcony rail laughing that his next concussion could kill him.
I do not personally remember the exact circumstances of most of my concussions. I am fairly missing large swaths of time around most, although I have vivid memories of certain events that were not close to any of them. One time when I was a kid we were watching a fight on TV. One of the fighters got knocked out. I said that I wondered what that felt like and everyone started laughing at me.
Most of my “accidents” were not necessarily caused by stupidity or recklessness that I know of. But they were related to somewhat risky past times like riding a bicycle long distances through all types of weather conditions when I was a teen and young adult and spending a lot of time riding horses bareback when I was a child. It also didn’t help that I have a large head which seemed to get banged into a lot. Maybe I was top heavy? I have a grandson with the same problem. His pediatrician joked that he was in the 99th percentile as far as head size goes.
I can remember being taken aside by my teachers in elementary school on more than one occasion because they thought that I was being abused by my parents because of all of the injuries. I think that people who get hurt a lot as children do not fear injury nearly as much as those who are more sheltered. Kids today are way too sheltered in my opinion, although I believe that helmets are a very good idea for them.
