Just this week, while glancing at the TV, I saw a man purported to be a sculptor or a 3D artist (I wasn't listening) signing his name; he was left-handed. It suddenly dawned on me that there must be a higher proportion of lefties among artists than the general population, so I started asking around.
Jay Farnsworth thought it was a possible/probable; Anna simply said, "Of course!" and she's, of course, a leftie. So there you have it. Are you a leftie?
Me, I'm your ordinary rightie, but Mom and Brother were born lefties and were "corrected" so I guess I'm not devoid of the leftie genes.
And if I stretch this theory, I'm told that in Japan there is a much lower proportion of lefties than there are in the US; I haven't seen any statistics, and it could be because of the more rigorous correction, but it would also make sense that as a nation of left-brainers, we make better followers than innovators. But that could be too far of a jump.
OK, gotta go. I got a very polite "Where's my scarf??" inquiry; about time I got on to it.
