When I can't sleep at 4am, I find it oddly comforting to imagine a woman thousands of years ago- Paleolithic era, say- who also couldn't sleep and lay awake worrying about similar sorts of things- how to get her DS to get up and go on the mammoth hunt rather than sleeping in or what to feed everyone in the morning when her family had eaten all the nuts last night that were supposed to be for today (possibly giving away my lack of knowledge of the Paleolithic here).
Does anyone else take comfort in odd things like this?
