I write naturally with my left hand but if I want to think about what I am writing then I use my right hand. It was a bit disconcerting when, because I had tennis elbow I had to use my right hand to write in the office, quite a few people commented that they could now actually read my writing. I play guitar right handed but have to clean my teeth left handed (except for my denture which I can clean with either hand!!!!!!). Mixed up - who me?
