  supposedly the left side of your body is controlled by the right side of your brain and vice versa. The right side of your brain also controls art / maths etc while the other side controls other characteristics so apprently you’re more likely to be arty /musical / good at maths if you’re left handed. I am lefthanded and I am musical and mathsy, but not so artistic!
