I discovered something interesting yesterday. The signals from my brain that deal with writing just can't seem to not go to my right hand.
Here's what I mean. I was doing a project at work that required me to use two different colors of ink. After switching back and forth for a little while, I decided that surely one of the benefits of ambidexterity would be dual-wielding my writing instruments. So for the first time in over two weeks, I wrote with my right hand.
The work went much quicker that way, and I was congratulating myself on my ingenuity when I realized that as I wrote with my left hand, my right hand was twitching. I hadn't really noticed it before because it was usually holding down my paper or stowed in my lap where it wouldn't get in the way.
But now, I could see what was happening. As I wrote, the right hand twitched as if it were writing too. My brain was sending signals about writing, and enough of them were leaking through to the right side that the tip of the right pen was tracing out minuscule letters.
They were not mirror images. In fact, with a little practice I could probably write two copies of something at once. Thankfully, I'm no longer in school where I could be set to writing lines, so I can't imagine that skill would help me at all.
I just had to remark, though, on the amazing power of habit. I wonder if that twitch will go away as I improve? Or will it spread to the other side, so that lefty twitches while righty writes?
