why am i so accident prone?

i just jammed my hip bone into the stair railing...okay, that probably was a fault of mine, but one would have thought my hip was WAY below the height of something like the stair railing...

came back yesterday and found a new scratch on my ankle, still bleeding. and i looked a bit further down my feet, i saw the remains of another scratch on my big toe. (this one is more problematic cause it hurts and itches at the same time, and i use my big toe to slide into my splits) then since we're on the path of wound self-discovery, i decided to take a look at the rest of my leg. wala! blueblacks on my knees and ankles, scars for previous scratches, it's amazing how many times i can get stepped on/knocked/elbowed on the same day, not to mention same week.

is there something wrong with me? wonder if the wounds are inflicted on me by accident or otherwise.
