Nor should you be. It just doesn't pass the sniff test that something so ubiquitous as these folded proteins should suddenly cause a new degenerative disease with such marked and significant symptoms never before documented in human history. Further, that it would be transmissible in the manner suggested doesn't strike me as quite right either.
OTOH, that organophosphate pesticides, some of which are known neurotoxins, might have delayed, second order combinatorial effects with background trace minerals is indeed possible and would certainly escape normal screening during product qualification.
Very interesting.
Why, maybe, such a long incubation period?
