I've tried counting in binary on one hand but it's kind of hard to do without getting help from the other hand (to keep the bits either up or down and not ``indeterminate''). Two hands would be hard. Forget two feet too! There's lots written about binary finger counting. Here's one video showing counting to 31 on one hand: http://www.youtube.com/watch?v=z8p-tLD5E5A". It uses ``negative logic'' though -- I prefer finger up = 1, finger down = 0. Jesse,

I try to do a mile in the neighborhood of 30 minutes, with early 25 meter laps taking about 7 complete strokes (both arms) and never expanding beyond 9 complete strokes. It's important to count strokes and laps, but it gets boring. To make it more interesting, I've also been thinking about how I might go about counting on my fingers and toes. If you take each digit and think of it extended as having a "1" present in its position, and curling under to represent a "0", you have 20 positions, which permits representation up to (2**23)-1, which lets yo count beyond a million just using your fingers and toes - right? Hint: use your fingers for the least significant bits as they change the most. When I swim, I count both my laps as well as the number of strokes per lap.
