I've measured my heart rate 462 times and typically it beats 69 times per minute. In the past 119 days, I've pushed 1,399 commits to this site, gone on 29 runs & eaten 15 burritos. I love a good burrito.
This seems extremely tedious to do, but I find it interesting. Screw Facebook privacy concerns - he has every place he's gone to, every run, his pulse, vitamin levels, etc. all tracked. Why?
Google seems to want to make this easier to do.
His website is pretty sweet, though.
