Right, I agree fully, but have noted a lot of people that have variations of schizophrenia, go full blown, 'apostle, savior, or head of the Holy Roman Church', sort of stuff.

As far as causes, I actually lean towards greater mental gifts, but a society that chooses to simply see illness rather than exploring potential benefits.... Our minds are not a very 'open' topic, while the government spends a lot figuring it out behind closed doors.
