I may be relaxed but I'm not drunk....
how many times haven't you woken up just before the alarm, that's what nobody never registers because it doesn't seem strange. Unless you make a mental note of all the mundane things that happen you can't really put the seemingly strange things into context.

I have to disagree on this one! I "know" what time I want/need to wake up. If I failed to wake up at that time I would have "overslept", which very rarely happens (not even once a month). I never actually set the alarm. I can therefore say, with reasonable confidence, that I usually awake "on demand".
Hotspur, if a child lives to one day, and an OAP dies at 100 years, I guess the average life expectancy would be 50 years? I'm sure that historically less than half of children born wouldn't make it to 5, so you do the math!
