I was reading about handedness and ways to test it. (I'm right-handed.) One of the tests was, once for each hand, to write your name and circle it. I did that; and it felt odd. I hardly ever write with my left. It was all like, "do wha?"
Interestingly, my results claim to show right-handedness, but mixed brain-hemisphere dominance.
[Also, long ago I taught my left hand to use a right-handed mouse on the left side of the keyboard, because I was getting some repetitive strain from exclusively right-handed mousing. (I use a computer all day long, most days.) So I can move the mouse to either side of the keyboard quickly without changing any computer settings. I've done this for years now. My left hand and arm get tired more quickly than my right at this task, though. (Now if I just learn dvorak, my computer will be as confusing to others as possible!)]
There are quite a few unusual anecdotes about lefties on the web. I read that Leonardo da Vinci wrote his personal notes from left to right, with his left hand. Others might have to use a mirror to read them. Hmm. So, I took a pencil in my left hand and printed my name backwards. Just like that! Holy cow! Okay, the descenders on my R's were a little funny, but I found I could just write (print) things backwards with my left hand without thinking about it. But only if I didn't think about it.
Then I'm looking at the page and my brain is saying "wtf? I did that?"
I juist held the page up to a mirror to check. Even the S's are correctly mirrored!
Now my left hand is having... trouble... typing. It took typing this whole post before it felt right again.
