I used to be able to wake up moments before the alarm would go off, no matter what time the alarm was set to. It wasn't perfect but I was pretty good at it and my internal clock was fairly impressive. This doesn't mean I would get up at that time but I'd look at the clock and groan.

I'd like to test this.

So, tomorrow morning I will try to wake up at 7 AM without the use of any kind of alarm clock. Heck, I don't even think there's a clock in this room within my eyesight so that will make it that much more difficult.

7 AM. Let's see if it works.
