Ummm... You have one of those funky Microsoft ergonomic keyboards, eh?
It's really a matter of my knuckles only bending one way.
I remember one continuum where every other finger went the opposite way. It was a very peaceful continuum because people couldn't make fists so there were no fighters. Also, instead of left and right handed people we had people whose index fingers curled up and those whose index fingers curled down. That would have made gun manufacturing interesting, but they didn't have guns. Golf and baseball were really something.
