Up to 1845, half of everyone born was dead by age 35. There were no chemicals in their food then, the air & seas were clean, animals were not fed any weird stuff.
Today the average life expectancy has nearly doubled thanks to science, to medicines, to vaccines
I mean... there definitely were chemicals in their food then. Food adulteration was a massive problem. So was pollution in many places.
Like, I agree about the medical advances made, but that life expectancy change was also about legislating against casually poisoning people.
