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.

I’m quite impressed with, though the site is horrible, they offer a nice service. But I’m still doubting whether this is the kind of item best purchased online. Hm. To be continued.
