How I Sleep|
Wow that's really interesting. I'm similar to you, I can sleep through and after just about anything. Even when I'm stressed out of my mind I can just put my head down and -
I'm banninated from sleeping next to Em's alarms because I tend to reach over and switch them off before I realise what I'm doing. I've also been known to talk and do some pretty crazy stuff while asleep. It's also interesting to know that, while everyone does it and we're worse off without it, there's no *real* theory as to what happens when we sleep and why we need it - mentally I mean. TOTALLY interesting to me, I can tell you.
I agree, there is definitely something about books that makes one tired and more likely to dream (R.E.M-styleee).
I pity people who can't fall asleep at the drop of a hat. My mom is one, she finds it terribly difficult to fall asleep and stay asleep. Mind you, she drinks coffee a lot and a lot of coke. I think people generally underestimate the effectiveness and affects of caffeine.
I find caffeine has no difference on my ability to sleep, just my inclination to and quality of sleep (I find it easier to forget to go to bed, and if do I go to bed on time, I sleep, but fitfully.)

Best theory I know of for the evolutionary origins of sleep is that it is a safety mechanism - you expend less energy and take less risks by sleeping through to 'unneeded' bits of the day. Various biological mechanisms (mostly mental) then evolved to take advantage of this downtime, rather than sleep being 'needed' as such.
