I came to say this. I have also noticed a strong trend amongst people from each generation for health.

Teflon was introduced in 1938, when my grandfather was 11. In the 1955, when my father was born, is the last time that we have Teflon untainted blood from. At some point between 1955 and 1985 when I was born, Teflon proliferated to the point that it was being found in every blood sample around the world.

So my grandfather lived ~40-50 years without being massively contaminated with Teflon, my father probably got to adulthood, and I have never been without it. Now an anecdotal sample that follows a larger trend. My grandfather is in his 90’s with pretty good health and is still going pretty strong. My father and both of his siblings are in their 60’s-70’s and all have failing health, and I know so few people in my own age range that are actually healthy without autoimmune disease or other systemic issue that I couldn’t fill a high school auditorium with them.
