As a left-handed roommate of mine in grad school once observed, presidents are disproprortionately left-handed. I think that provides ample evidence that right-handed people are better
Left, although I cut right-handed. (No left-handed scissors in school which traumatized me forever ) I am also better at throwing a ball right-handed, although when I play miniature golf, I am never sure if I should do it left-handed or right-handed, and usually do it differently on every hole.
Left...but if that hand tires I switch to the right. I play most sports right handed, although for tennis I use both (no backhand). At home my mouse in on the right. At work it is on the left. Either way it works for me.
I use my right hand for raquet sports and the *majority* of my writing. I use left on writing occasionally (almost daily though), most other sports, when I eat and when I drive. The rest I use interchangably.
right handed, but I eat with my left hand...
my mouse is also on the right and my work is on the left. My phone is on the right, but I have to have the receiver to my left ear.
