You know when you get an idea stuck in your head and it rattles around in there like the chorus to a catchy song and you can't get it out no matter what you do? This happens to me fairly often.
Lately I've been thinking about head injuries.
I'm not really scared of getting hit in the head, really, it's more like I have this idea that sometime when I get older I'll get a stroke or dementia or hit in the head with a coconut and have a complete personality change.
I'd like to think I have a fairly good disposition at the moment. For whatever reason people seem to like me, so I guess I'm doing something right.
But all that could change with one future accident.
Would I become belligerent? Racist? Would I turn into one of those guys waving misspelled placards and screaming about the government? The worst part would be overhearing people say, "Yeah, Scott's kind of a dick now, but he was a great guy before that coconut fell on his head."
And that's the greatest tragedy of my future personality change; nobody I'd meet since my accident would know how awesome I was before. It's pretty sad when you think about it.
Of course by then I would have alienated all my friends and family, and would only have the staff at the poor people nursing home to scream at.
The funny part about all this is that I know that the odds of something like that happening to me about equal to winning the lottery or getting eaten by a shark, and I realize that this is one of the dumber things taking up space in my head, but it still bounces through my head every once in a while like the chorus of a classic rock song.
And again, I'm not actually really worried about this happening, but if I'm wearing a helmet the next time you see me, try to understand.
