i thought that it was a standard to do this test by which hand you used to write with. at least that's what i've always heard. lefties are right-brained and righties are left-brained. that's why i chose left-brained but i didn't even see the thing about thumbs till after i'd voted. if i had done it the thumb way, i would be right-brained. oh well
