Insomnia

Once again, sleep hasn't featured heavily tonight.
Am I keeping myself up? Probably, but that's beside the point.
The thing is, why do we have to sleep when we're told? Surely if the world was more flexible in many, many ways we'd be happier. It could be said that the reason we sleep at night is because you can see what you're doing during the day - i.e. you can't farm, trade, or read in the dark. Yes, I am lumping mankinds ills on post-hunter-gatherer society.
But, I suppose, everything's headed somewhere good, isn't it?

I'll class this as "dog-tired thoughts"
