*Total Recall*

[since 2001] Microsoft researcher Gordon Bell…has been compulsively scanning, capturing, and logging each and every bit of personal data he generates in his daily life.

This trove includes Web sites he's visited (221,173), photos taken (56,282), emails sent and received (156,041), docs written and read (18,883), phone conversations had (2,000), photos snapped by the SenseCam hanging around his neck (66,000), songs listened to (7,139), and videos taken by him (2,164). To collect all this information, he uses a staggering assortment of hardware: desktop scanner, digicam, heart rate monitor, voice recorder, GPS logger, pedometer, smartphone, e-reader.

Here is more and that is all from the interesting new book Total Recall: How the E-Memory Revolution Will Change Everything, by Gordon Bell and Jim Gemmell.  You may recall that I mention Bell in Create Your Own Economy.  I don't personally have the ability to operate all that technology.  So if I could measure only five things from my daily life, what should they be?  What would yours be and why? 

Lately I've developed a new theory as to when I sleep especially well (in general I sleep well so the variance is not so large).  I believe that I sleep especially well when I end up going to bed at exactly the same time I expect to be going to bed.  On the unusual occasions when I don't sleep well, it is because I have been winding down my body and mind before I actually have the opportunity to fall asleep.  Somehow when the later chance to sleep comes, it is too late for that sleep to be deep.  Or so it seems to my mental econometrics; it would be interesting to measure it.
