This seeems like a sensible analysis of the 9-to-5 office worker approach to life. However. I suspect this does not project well on the lives of entrepreneurs and self-directed workers. For example, I believe if you were to include on this survey non google staffers, like entrepreneur farmers, merchants, mercenaries, i.e. roles of independent, founder devs, and any self-directed entrepreneurs that live their profession 24/7, i suspect you'd find that they are far happier than the rest of the sample set. There is nothing wrong with overlap of work and play, if work IS play and you enjoy it. The vast majority of entrepreneurs do because as owners they can do their job as they see fit. Anecdotally, i see this evidenced quite often when i see entrepreneurs retire due to external pressures: once founders give up their raison d'etre, their health decline is fast and dramatic.
