From my own experience I think it's ultimately unhealthy to justify working long hours with "internet surfing, lunch, chit chat, etc. mingled in." While it's easy to rationalize staying late thinking "yeah, but I took a long lunch, chatted with so-and-so, ..." at the end of the day you have that much less downtime away from work. I find I am much happier when I can keep those distractions to a minimum, then force myself to go home. I get more done outside of work and sleep better, resulting in being more focused and productive when I am at work. Allowing work and the rest of my life to blend together both makes me less productive at work and results in having less time for everything else.
