I'm the same way, sorta.
Lefty: Write, eat, soldering iron, etc
Righty: throw, kick, golf
My girlfriend noticed something when I was making a sandwich the other day. Apparently, I chopped up a tomato and an onion with my right hand, but I spread mayo on the bread with my left. Also, I use a mouse with my right hand, which seems like is should be a left handed, more precise move. What a weirdo!
