I draw/use a tablet/throw/play baseball with my left, played lacrosse with my left and right, cut paper with my right, and use a mouse with my right. Oh, the good old days when teachers would give me the left-handed scissors in elementary school and I would try to steal the right ones as they hurt my hand.
I'm mostly right handed here. Mouse and pen and scissors. Sometimes I could eat stuff with my left, but mostly right. In my culture, kids are taught to 'raise hand in class with right hand, cuz left hand is to wipe your ass.' But then we shake hand with left for boy scouts. Duh. I could drive with my left though...
It's flipped, left dominant are thought to be right brained and right dominant are left brained. I think that's all be debunked though, the idea originated in the 1800's. If there is an over-representation of left handed people in creative fields it's probably a self fulfilling prophecy.
