Got more scars than I'd care to count. Some of them (on my head and face) were due to calculated risks (fencing), others came about through accidents... like falling into a broken bottleneck, having an army knife slice through half of my right thumb, or doing a flip in the living room and landing forehead first on the corner of a mahagoni table (kinda looks like a Harry Potter scar...).
I was stabbed in the left by some drunken ass with a switchblade, but upon fleeing the scene in a hotwired car he caused an accident and lost almost his entire left leg in the process. That's karma for you.
