Right handed here. I can only think of one thing that I do with my left hand. All the rest is right-handed. Anyways:
"One in every 10 people is left-handed, and males are one and a half times more likely to be left-handed then females, according to Lefthanders International. Medical researchers have looked long and hard for what causes people to be left- or right-handed. Their answer? The same reason why brown-eyed people have brown eyes: genes that manifest their trait one out of every 10 chances."
