Bought too many books on vacation and tore a rotator cuff lugging my carry-on through the airport on an uncomfortably short layover. That one still flares up when I overdo it.
Stepped half on, half off the pavement while lining up a shot and instinctively saved my camera rather than my poor knee, which took the brunt of the fall.
Broke a souvenir hurricane drink glass while washing it and sliced across three knuckles in the process.
Fortunately I don't seem to break easily, but I don't bounce the way I used to and I'm certainly not getting any more graceful with age (not that I was particularly coordinated to start with!).
