I think this "2-3 hours of real work per day" stuff is a myth. Or maybe this depends on a definition of "real work" that only entails "heads-down" "in-the-zone" coding. Still I think it's too low. I'm 44 and just a month and a half ago I had to intensely focus 9-10 hours a day to meet a very aggressive deadline (PG you are so wrong about us older coders ;) It was exhilarating and while I wouldn't want to keep that up for months on end, I think 5-6 hours heads-down is definitely do-able. What about the other 2-3 hours to come to an 8 hour day? Well, there's analysis, documentation, email, etc. Some people like to do this sort of thing first thing, but then is when I focus best. Indeed by mid to late afternoon my brain is craving television, but I force myself to at least think about problems, even if I'm not solving them through code. And it usually pays off, with a solution through code the next morning. Anyway that's my experience.
