Yesterday evening, while I was enjoying a glass of wine, it came to me that perhaps I should consider getting up at 4:00 AM, just to get an idea of the sorts of things that would be going on at that time. I didn't do it in the end – I slept right through - but if I had done it, the interesting thing is (well, interesting for me and perhaps a couple of sleep researchers somewhere in Stockholm) I wouldn't have needed an alarm clock because I've found if I say to myself as I go to bed something like, "It's important that you wake up at 4:00 AM - I won't go into details right now, but suffice it to say you must wake up at 4:00," I will wake up at 4:00, probably a little confused as to why I'm up at that particular time, but nonetheless awake and ready to go. Funny old thing the human brain; it can think up absolutely mindless drivel like the TV show 'Two And A Half Men,' and then do that thing where it can wake you up at 4:00 AM without ever being given any clear reason why it should.
