I'm right-handed, and work in IT, having once been a programmer. That's a bit creative, right?
I also try to write, and am 50,000 words into my novel. Daughter #1 is right-handed and is an actor and singer/songwriter, daughter #2 is left-handed and her only creativity is her love of music (listening to). Daughter #3 is right-handed and is quite the little artist. So I don't think we can typecast lefties and righties too much...
