I'm also ambidextrous. Whilst my writing with my left hand is not quite as clear as it is with my right, I can write legibly with both hands. I also eat left handed, skate & surf goofy and predominantly write with my right hand. My grandfather is also ambidextrous but was also forced to write with only his right hand. As a fitter and turner, he found being able to use both hands a very handy thing.
