If you live in the U.S., there is a substantial chance your demographic has been affected by lead poisoning. https://www.pnas.org/doi/10.1073/pnas.2118631119 https://www.pnas.org/doi/10.1073/pnas.2118631119 I think many of the problems you talk about can be traced to things like this. What I see is that after some inflection point in industrial development, a race between stupid decisions and smart solutions began, on a massive scale. Antibiotics is a good example of this sort of thing, but it's not just technology that gets rushed but laws and ways of living. For example the GI bill created a standard of suburban living that we still expect to this day. And for what? We're not in a war. Ultimately I think we live in highly experimental times. You could have cutting edge benefits or cutting edge annoyances and combination thereof.
