Hmm... I've never tried to list all of mine in one go. Lets see...
Many cuts when young... generally accident prone. No breaks, that I can remember. I just leaked a lot. E.g. coming back home to my mother, who couldn't stand the sight of blood, after a local "gang" fight had finish with me getting a lump of rough concrete in the head. I tiny cut to the top of my head, but they bleed masses. I walked how and was eventually carted off in an ambulance. I think my mother waited until I had left, before fainting.
So, I have scars in various places. Plus the appendix scar (near to perforated before they operated, I gather).
Hung myself, briefly, by the palm of my hand, on a hook, climbing over UI wall I shouldn't have been climbing over. Hook was rusty, but sturdier than my hand...
Pencil in above eye, glass into hand (more than once), spun tin can top into face, gravel in knee (repeatedly), corrugated iron into inside of elbow (quite hard to do that one... also climbing over a gate that I shouldn't have been climbing over), fell from tree, stamped foot down (while paddling) onto base of broken bottle, cut lip on blade of grass(?), bee sting in mouth, needle through hand, nearly chopped top of left thumb off (remains of the nail were surgically removed - later, it was painful when the "kind" nurse slowly took out stitches from under where the nail had been).
That takes me to about age 11.
Grammar school included... ski tip into hand, more glass into hand, iron railing into hand. Managed to avoid shooting myself, which is a surprise, as I had to be in the "army cadet" stuff for a bit, with occasional live ammo, and had goes on both a sten gun and an SLR. Failed to blow myself up a few times, while experimenting with pipe bombs. Did blow up a concrete path.
Skip to university. Car crash. Me as passenger, back wheel fell off, rolled several times, which was surprising, as we had only been travelling at about 30mph, I recall the windscreen coming back at me, in a thousand pieces of toughened glass, just before my head left a visible dent in the roof of the van. I ended up in the back, unconscious. Driver was lucky - saw the van afterwards, and the roof had folded down to form a point, just an inch in front of where his forehead had been. A month later I started getting headaches. I put it down to partying. One on the Friday night (where I rescued someone trying to commit suicide out of a window - a first floor window, into a bush? so not a very serious suicide). The next party was on the Saturday night, in our rooms at college. I gave up my bed to a visiting friend and went to sleep elsewhere, on the floor. Headache was worse on Sunday. Eventually went to hospital (about midday) where they diagnosed a subdural haematoma. They drilled three burr holes in my head at about 1am Monday morning (interesting sound that, having holes drilled in your head - local anaesthetic plus happy pill - they want you conscious) and took out 30cl clot.
What next... hole in back of month from foil blade, with plastic tip still on. One should always wear the mask, even when "play" fencing. Nothing much more spectacular.
More recent stuff... (I seem to have stayed relatively non-accident-prone for a while after college)...
Dislocated knee while changing TV channels (which eventually resulted in me giving up Kung Fu). Again in a car crash, as a passenger, suffered fractured pelvis, which was no fun. Fell out of van (drunk), and had two more (drunks) fall on top of me... bruised/cracked ribs that became infected some days later. Tripped over marquee guy-rope and hit head on next tent spike along. Unconscious briefly (drunk, too). Three stitches in between my eyes (lucky, huh?). Ripped muscle in calf while trying to push a car.
I think that covers most of the memorable ones (I had to go back to edit in the pelvis one, I'd forgotten it!). I like hospitals. Certainly there are at least three times I would have been dead, bar for them.
