Another advantage of schizophrenia, perhaps evolutionary, is tirelessness. While a few schizophrenics complain of generalized fatigue, particularly in the early stages of the illness, most patients do not. In fact, they show less fatigue than normal persons and are capable of tremendous feats of endurance. They are not fatigued by examinations lasting many hours. They may move about day and night, or work endlessly without any sign of being tired. Catatonics may hold an awkward position for days that the reader could not hold for more than a few minutes. This suggests that much fatigue is a product of the subjective conscious mind, and that bicameral man, building the pyramids of Egypt, the ziggurats of Sumer, or the gigantic temples at Teotihuacan with only hand labor, could do so far more easily than could conscious self-reflective men.
