My hands are weird.
I can only write or draw left-handed. But when I'm throwing a baseball or football or something like that, I have much better distance and aim when I use my right hand. I also kick better with my right foot. And I think I punch better with my right hand too, but it's hard to be sure. But when I'm carrying something heavy, it'll be in my left hand.
And as I found out last night - I bowl better left-handed. Well, I think so. I bowled 3 games with some guys from work. At the beginning of the third game I decided to use my left hand, and was surprised to find that it went much better. At least, less painfully, and the ball slipped out of my hands a lot less. Even though the second game (still using my right hand) was the only one when I got any spares or strikes. But that's probably (hopefully) just because I had used it for two games and therefore had more practice, whereas my left hand only got one game.
