Time: what a concept. Wish I'd invented it.

Time is such an amazingly fluid thing.

For instance, how long, really, is an hour? When I'm at the dentist (as I was yesterday), an hour is A WHOLE FRIGGING HOUR. But when I'm focused on a knotty design problem, that same hour could be just an instant; I look up and it's been three hours or five or six since I last checked the time.

Where does that time go? If you don't pay attention to every moment, do you lose something valuable? Time zips by; time drags. Yet it's all divided into the same units of measure: each second lasts just as long as the next and the next and the one after that.

But it sure doesn't feel that way.
