There was going to be a point to this...

but I think it escaped.

When I'm sleepy, I don't often go to bed. When I'm hungry, I don't often eat. When I'm curious, I don't often think. At least, not using the scientific method; I prefer to 'philosophize'. Didn't do Aristotle much good though, did it? Great thinker, perhaps, deep thinker, but with much wrong information.
One good reason to blog or keep a journal - you can go back after a month or so and ask, "WHAT was I thinking?!"

I think I'll go to bed now.
