The other day, I bumped my head into the opened boot of a car while loading stuff into it. It doesn't hurt now, but it did, rather badly, for a few hours ensuing.
There isn't a staircase in my life that I've used and not fallen down on. It is quite amazing, in hindsight, that I've not gotten seriously hurt so far...
I guess that is the positive side of things. Despite living in constant presence of small injuries, I've not gotten seriously hurt so far. That's got to be good, right?
