 So it's like, as we've industrialized, many people have had issues with working inside of factories and having exposure to certain classes of chemicals, but then also there's just on a mass population scale, those that have progressed to, let's say, just advancing countries into whatever first world countries that they're exposed to BPA and other forms of exposure to endocrine system implication that then cost things like infertility. This is all very interesting because there's so many downstream effects that it's hard to measure longitudinally over like 50 years, what it does. I mean, we were just talking about this earlier this episode, just people being jammed into little boxes on top of each other in metropolises, well, when you don't get that much natural light, when you're not getting that much exposure to fresh air, when you're not getting that much exercise, you're not getting enough sleep because there's just economic machinery pressuring you all the time, you're far away from your family, you're far away from raising children, all this type of stuff. There's many downstream implications that happen, including the onset of cancer and cardiovascular disease and Alzheimer's and all these other things that are very difficult to measure this, the intricacy of the nuanced multivariability, yet it's quite physiologically evident on a moment-to-moment basis when you actually feel like you're divinely at your peak state of performance versus feels like me inhaling the cars exhaust on the street in a breath of air feels like it actually sheds minutes off of downstream my life versus indigeneity, people that are still living in complete symbiosis with nature. They have just a much more cohesive understanding of the interconnectedness of everything plus their environmental anthropological awareness level must be like a 90 on a scale of 0 to 100 and ours in metropolis feels like it's 20 or 30. It's disastrous, it feels disastrous.
