That is what I thought too, I read several paragraphs and thought, "did she take into account that all the kids had vaccinations?"
I know they came out and said vaccinations were not in mercury and were safe but still, we didn't have these problems at this level back when I was a kid.
Misdiagnoses? fraud? that might explain alot, but not all.
Whatever it is has to be environmental and not genetic, the Haldane problem prohibits anything spreading that fast due to genetics. It has to be some large change, possibly vaccinations, possibly changing from an electrical world to an electronic world, I don’t know if there’s anything else to add to such a list.
