Just because these metrics show evidence of how his time was spent, doesn't mean that's how he thinks of the year. He might think of it as time spent staying connected with far-away friends, while writing awesome code for a company he loves.

As a parent, I have often wondered how much of my time is spent changing diapers, getting water/milk/juice for my kids, overseeing clean-up time, doing bathtime, reading, etc. I'd love to be able to look at a metric of this over the course of a year. If, at the end of the year, I had an annual report which included all of that (and work time), it would be very interesting to me as a way to understand my life better. I already think of myself as a parent, and know that these are the costs of being one, but that's not the only way I think of my life in a year.
