Slept in untill 12:15 yesterday morning, I'm quite ashamed to say. But what the hell, it's my vacation time, so why not. Not looking forward to setting the alarm next week though. Especially since it's still dark when I have to get up in the morning. That has to be one of the advantages of summertime. I read a review of a device called the Sleeptracker recently. It monitors your body and continuously looks for your best possible waking times. Sounds interesting, but $149 is a bit much just to give it a try.
