Wow, some great stories here. I have a few small scars, with mildly interesting stories:

My lower lip has a faint but noticable line and a bump inside, from a faceplant into gravel from a bike when I was 16 (story told elsewhere on this forum). Broke two front teeth, pulled them halfway out and incidentally split my lower lip wide open.

My calves have two matching circular dotted scars about the size of a coin. Any horse people recognize those? I rode race horses when I was 16-20, and one race (or exercise race, can't remember) the stirrup straps royally grabbed onto the skin on my calves and abraded off a layer or three. Everyone on the racetrack had those dotted scars.

I have a small raised line on the inside of one knee. I had my own horse, she was unshod, and I was carving off a little off her hoof that had grown too long and started to split. The knife slipped and tore a hole in my pant leg, but I didn't feel anything until I noticed that my FOOT felt wet... Long gash.

And my right forefinger has a distinct triangular scar at the base. I tried to punch open a window (long story, locked out, young and stupid and macho), cut myself a bit, freaked out and jerked my hand back again towards me. Result was a BIG chunk cut out, blood spurting out in a pulse. I managed to stop it, but when I tried to remove the bandage again out came a little pulse fountain again. So I called a dr, who drily told me: "If you stopped it the first time, you can stop it again. You don't need stitches."

And now of course I have a zillion little cat scars from our small but ferocious tiger, but they are temporary.

The only times I've hurt myself semi-seriously (broken bone, kicked in the head by a horse once) I healed up without scars. A friend of mine used to be irritated over how she hurt herself in invisible places while I got "hero scars" - minor injuries that didn't hurt much but were very visible
