yeah but a sizeable part of the discussion here has been about women with menopause starting to show schizophrenic behaviors. So that might be a significant amount of the schizophrenic cases in the population.
OK, I just figured if there were specific large groups of schizophrenics that manifested outside of prime procreative years that it might be a reason for it to not be such an evolutionary mystery. Of course it was unlikely this was the case as surely some of the people claiming evolutionary mystery would have thought of it and ran the data.
