I'm not sure... I kinda use both for most things, but when it comes to what passes for handwriting I usually use my right, although I can write with my left, I'm not as fast, but some people say it is more legible, but I use the computer mouse with my left, but I usually brush my teeth with my right, except when I pick up the brush with my left first and then sometimes it's just easier to go ahead and do it with my left, but I open beers with my right, unless I don't, and when it comes to typing run on sentences in threads I seem to do most of the typing with my left because I don't hold my hands on the keyboard the way you're supposed to and sometimes I have to look at the keys to do it. So... who read all that?
