From a different angle: I spend more time with my office mate than I do with my girlfreind. I eat as many meals with the group admin assistant as I eat w/ her. It seems that writing this off as "just work" is dismissing a huge portion of my life.
I understand that I am lucky in that I love my work -- but still, instead of measuring things like work week, why not have articles and posts and what not devoted to "how to better integrate and avoid the redundancies".
