I'm left handed, along with most of my friends, my dad WAS, but he was forced to change. He can barely use either now lol.
Anyways, I find that being left-handed is nice for many things, except writing in notebooks and playing computer games.
My right hand gets a little shaky when I play cause its not my dominant hand. My left hand however...heh...can do a lot of things, faster, and more accurately than my right hand could ever imagine.
Except make a straight line.
