I was in an Alexander Technique workshop recently that asked me to write down ten things I want using my right hand, then again using my left hand. I was terrible at writing with my left hand. But it intrigued me. If indeed the right hand is wired to the left side of the brain, and the left is wired to the right side (an oversimplification, but stay with me here), wouldn't it make sense that using the left hand to write with, using both hands to write with at the same time, would be a great way to integrate the two hemispheres of the brain? I've been trying it. I write in my journal with my right hand, then answer with the left. I have little conversations back and forth with myself. I suppose that's a little schizophrenic, but it's an interesting ongoing experiment.
