>Do you think that if you worked nights and weekends (say another 20 hours a week) your total productivity would be diminished vs. your normal week because those extra hours aren't productive? Yes, but it depends on what type of work is required. In creative work: if I don't get enough sleep, enough exercise, enough relaxation time, my personal productivity falls to at most a quarter of normal. Total productivity is surely less. In grunt/repetitive work: my productivity is affected a little but probably not enough to decrease total productivity, and I've noticed my work is appreciated more because I appear to be more 'busy'.
