How have I not seen this thread until now? xD
I'm left-handed! I write and eat with my left hand, which are the two most hand-driven tasks I do! I use a computer mouse right-handed though, and played violin right-handed (since there was no such thing in elementary and middle school).
I feel the pain with lefties though, considering how there are no school desks for us, or how typical notebooks put pressure on our hands, and of course, pencil graphite winding up on the side of our hands. :|
