Same here... I am also both handed.. I use my both hands to type on PC. Can't do with only one hand. - Digital -
I write left, but use the mouse in my right hand. Some lefties drag the mouse all over the place and mess up the office.
here are some interesting things about the use of your left hand/right hand: If your parents are left handed, then you are more likely left handed because you learned from your parents. You can teach yourself right handed or left handed. For most people, I say 9/10 people are right handed, then we have one person is left handed. I'm not sure why. I don't think that have anything to do with or related to your left brain/right brain. Most people use their left hands for picking nose, wipe their ass, ... Many people used to think, left hand is the evil hand, dirty hand. Right hand are their stronger hand, for holding pen, playing guitar, shake hands with other people, ... (I know in some countries, they use their left hand for shaking hand instead, it shows respect to the person you shake hand with).
