Took the trouble of bringing my medkit to the big game at Rawdon. It was centered at the back of my belt. I slipped while running backward, fell ass first on the pouch, and heard a cracking sound.
Already having broken my coccyx, I feared the worst, and the fall hurt like hell. By chance, the cracking sound was just a roll of tape in a plastic sheath being crushed.
The coccyx did swell though. Learned my lesson, I now always keep that pouch off center when I work now.
