Brush with death

I was nearly brained by a falling branch during my run the other day.  I don’t know what made me jump out of the way – maybe I saw the movement? – but SOMEthing warned me, which was good because this branch was LARGE.  It could have done serious damage if it had landed on my head, which I’m pretty sure is what would have happened.  (It just scratched my calf.)  A couple of people saw it and came over to check on me, but I was totally fine, still on my feet, aside from being a little shaken.  I have NO idea what made it fall, at all or just then.  It wasn’t terribly windy, there weren’t any animals or evil henchmen cackling up in that tree, and really, what else could have caused it if not angry squirrels or evil henchmen?
