So if you could write while cycling...?

I value your willingness to think out loud (and in public). I don't know if this is a related phenomenon, but sometimes I seem to improve my thinking by talking with someone... a lot oftener than I sometimes wish, I interrupt myself, because as I'm describing or explaining, a new understanding comes to me.

I'm not saying it's always a useful understanding, though I suppose like Edison's experiments, I can at least learn that X doesn't work.
