First I'd heard of your obsession so interesting for me. Also interesting to know that most people clap right onto left.

ha. I'm right handed but I figure skate and snowboard an other such things lefty. I used to be pretty ambidextrous until I badly sprained my wrist as a kid. My boys both struggle with natural lefty tendancies too -Hector now freely admits he is a lefty, but he writes right-handed. He went through a period of being acutely aware of the norms and wanting to be just like everyone else, so he was determined to write right-handed. But he colored left handed, he cuts food with his left hand, reels a fishing rod with his left....... (and now makes awesome catches with his left ;) ) Thor is totally mixed. But it is a struggle being lefty in a right-handed world, particularly when you're not aware that that's what's causing your apparentl clumsiness or inability to use everyday objects with ease (scissors, can openers....).

And I'm fascinated that there are so many things affected by handedness that you never think about. Like whether you turn clockwise or anticlockwise (counterclockwise) when you spin in place. And now, apparently, maybe, how you clap.....

Sometimes, I make the sound of one hand fapping.
