I broke a collar bone a few years ago doing winter sports. It broke very close to the junction with the arm so the doctor decided to put a long screw to hold it into place. Being both young and stupid, I smoke a cigarette before the operation, which is not recommended. I recall the exact moment clearly, it is when they started drilling into my shoulder, I could feel my whole skeleton vibrating with the drill. I suddenly woke up from anesthesia puking all over the place. I remember telling the whole operation crew that I was sorry for making such a mess (yes, I'm Canadian), then some sort of oxygen mask was replaced on my face, I guess they gave my another shot and I soon fell asleep again. I think I slept for over 12 hours straight after that, but I have no other permanent trauma.
