10:1 is the general distribution of us. This is regardless of geography or culture. We generally have to adapt to a right hand biased world, so we can use your can openers and kitchen scissors (with the blisters to prove it), but to be honest. I feel that chainsaws are gear up for us with the pull start on the left, far more comfortable.
I'm trying to teach myself to use a saw right handed, but it doesn't feel right. That said, if I was the subject of a serious kickback, I can appreciate that I would probably decapitate myself.
Oh yes, I do drive on the left. The rest of the world is wrong.
