I am right-handed and right-footed. I hold a hockey stick with my right hand at the bottom. I throw right-handed, I wear my watch on my left hand (now; I used to have it on my right), and I use my right hand for holding the stylus on the DS. But, sometimes, I forget which hand I should hold my fork with (left).
My test results are that my right brain scored 51.6% of usage and my left received a score of 48.4%. Seems about right, as most online tests are right (at least the ones I have taken).
