> I also notice that when raking leaves, or mopping a floor, I can never make up my mind which handedness feels more comfortable, and just switch between them. I feel similarly. I think with a lot of these tasks, the stakes are low and the dominant hand can have an adequate effect in either placement. On the other hand (ahem), I do not feel this way about shoveling snow. I have to use my dominant hand on the far end of a snow shovel because I can generate more power with more control that way (despite my right arm having less muscle -- per my other comment about my experience agreeing with this article, I hold my child with my left arm and now have more muscle on my left arm as a result). I think the aspect of being able to control the power feels more important because shoveling snow feels like, if I screw up the motion, I can potentially cause injury to myself.
