“There is no way we can have a normal brain today.” It’s possible that a hundred years from now, when they look back at us and ask why we struggled to pay attention, they will say, “They were surrounded by pollutants and chemicals that inflamed their brains and harmed focus. They walked around exposed to BPA and PCBs, and breathing in metals. Their scientists knew what it did to their brains and their ability to focus. Why were they surprised they struggled to pay attention?” Those people in the future will know whether, after learning this, we banded together to protect our brains—or whether we allowed them to continue to degrade.
