Feeling sleepy?

This weekend, a friend told me about research into historic sleep patterns - seems like not only do we modern people sleep less than we would need to as a basic tendency, but also differently.

Research points at two sleep phases, with a time of quiet-ish activity in between, being the usual thing a few centuries ago, before electric lights were common and turned the night into day. Are you curious instead of sleepy now?

Here's an article on a website called slumberwise, BBC newsmag tells us about the myth of the eight-hour sleep, and some guy I've never heard of before gave it a try.

This, I think, is very cool - and a brilliant example on how things change, and stuff will seem strange to our modern western culture is what was so normal it wasn't even worth mentioning a few hundred years ago.
