Although I am not conscious of it, I presume that it's me who's doing the rotating. Relative to my immediate surroundings, I have sat motionless for hours (as I'm doing now). Not entirely motionless, though. I manipulate the mouse and I type, and I drink vast quantities of coffee. Then, after all that coffee, when I go to drain the sump, I discover that the fly of my Jockey shorts has move over toward my left hip.

What makes me wonder a bit about my theory is that I live in the northern latitudes and when sitting at the computer, I'm facing south. If it truly is the Coriolis effect, I would think that my fly should rotate toward my right hip. But perhaps I'm actually stationary and my surroundings (including my shorts) are what is rotating. If that's true, though, then why is it that after a substantial period of time, I find I'm still facing south, not southwest?

Most confusing. . . .
