Honestly a serious question! I tripped over a few days ago and mildly sprained my right (dominant) hand. It will get better quicker if I rest it so I've been doing everything with my left hand as much as possible. The one thing I can't do is wipe my bum! After 50 odd years of never twisting my body that way I just can't reach. Now I'll be living in fear of breaking my right arm and having it in plaster. Think I'll start a training programme and try to twist a bit further every day. Can other people do it with either hand?
