My eyes have gone from better-than-average to blurry when 30cm away from my face, I have an overbite enough to be able to fit a finger between the depths of my jaws, I have too big a gap between my front teeth, I can't clench my right fight without the top segment of my middle finger first bending 90 degrees while the rest of the finger is straight (relatively, see next point), the same finger always curves outwards, my right ring finger from the middle bends about 10 degrees to the right, and I have a very small bald-spot that unless my hair is very short can't be seen. Oh, and I shed various areas of skin annually.
There, a list of very minor hindrances.
