I'm currently experiencing the regular phenomenon of waking up thirty seconds before the first of my three alarm clocks goes off. What's going on there then? (All very prompt, except this morning, I made a cup of tea and took it back to bed).

[penelope] Do they still have those "Teasmade" ("Teasmaid"?) machines that compine an alarm clock with a cunning kettle/teapot arrangement? If only they had figured out how to keep the milk cold (other than by making the houses so expensive to heat) at the same time the idea would have been a 10/10 perfect one, but it was pretty good even so.

(pen) One of your alarm clocks may make a little click or sound before it actually goes off and it could be this that wakes you. Or you are sleeping-the-sleep-of-the-extremely-desirous-to-get-to-work-in-time because of your new job.

[SM] Actually, I've had one of those "screech in your ear, make you a cuppa" devices for over 10 years now. I call it a "wife".

[Rosie] Come to think of it, it might be the central heating that wakes me.
[Phil] *gasp!* although the windy miller does have the same effect, but through a nicer process.
