Being someone who grew up ambidextrous (pitched both hands in little league/high school), it's always been funny to me. I golf right handed, but putt left handed because I don't "think" about the putt or alignment. I like cranking with my left hand because it just feels "weird" with my right hand, something that other people already shared.
If you want to see some interesting statistics on "dominant hands", look how many American hockey players shoot right handed. This is not the "correct" way for a dominant right hand hockey player, they should be shooting from their left side left with their dominant hand on top of the stick. Americans end up doing this because we learn baseball first, where we get used to setting up at a plate right handed. I blame my parents for teaching me baseball with a left handers catchers mitt, and then giving me right handed gloves. I do almost everything left handed..write, eat food, hit right handed in softball to place a ball, left for power..I am all messed up!
