I am right handed, but have some double dexterity-- which falls short of being ambidextrous-- so can use a screw driver in either hand, but i write with my right-- I eat european style (left handed), and i knit and sew left handed. there are other things i do left handed, but i can't think of them-- i don't really think about it-- i just pick up and do, and some time i do it with a right hand and some times with a left-- but each hand has, for the most part 'assigned' jobs. there are very few things i can do equally well with either hand.
