I'm not sure that's true. I doubt most people can't maintain productive focus for 12 hours of a work day.

  Really gotta define what sort of work. As a knowledge worker, I'm really only in the zone for maybe half my day now - I doubt that increasing the work day would get more highly productive time out of me. Maybe manual labour jobs may be better for that, but even there I doubt it, and they'll have physical exhaustion before I hit mental exhaustion, if only because it's much easier for me to be present at my work and NOT be largely productive (jokes about people leaning on shovels not withstanding).

  I doubt most people can maintain productive focus for 12h every day more than a few consecutive weeks. They may at the beginning but fatigue sets in and by the end they are less productive than after a good 8h day. I’ve seen it in others, I went through it myself. Perhaps in some fields it’s different but I doubt it. Even playing games 12h every day means you start making more and more mistakes than a fresh gamer. I’d say normal work will be even more tiring and stressful given the higher stakes. Especially for a knowledge worker.
