My right hand is (temporarily) bandaged due a small accident, been trying to get used to working with my left hand only for the past week.
Being a right hander, the loss of one hand can be surprisingly difficult. Obviously no gym or driving but its the little things that are the most painful: the brushing of teeth, daily ablutions, reading (holding a book open is quite tricky), eating (rather clumsily), dressing.
I am getting a bit better at thing, for example this post is coming a lot faster than the last. I'm also trying to draw some inspiration from this man. Some further reading on one armed pianists here.
