Yeah, I don't beat myself up about it. I think if it's anything in that direction, it's-- like you say-- vaccines plus all the other crap we're exposed to in a world full of chemicals. I'd add mitochondrial dysfunction to that list. Maybe most people, you can expose to a whole lot of chemicals and just get a little undefinable underperformance. And maybe you take people who are already not running at 100% in the mitochondria department and expose them to the same boatload of chemicals and you get autism. Who knows? You do your best, and try not to sweat the rest.
