I like the research (and the general class of research which is looking at trending changes in measurable activities to understand health) but it creeps me out a bit to realize how much about someone you can learn by combing through their 'digital exhaust' if you will.

I saw someone testing a remote thermometer that was pointed at people coming into a health clinic to measure how many people a day passed through the door and were running a fever. Useful? probably, creepy? definitely.
