Yeah the plastic in our bodies.... I somehow feel you're better off with a little toxicity in you, like you're more resistant to just the more toxic environment. I can't help but think if you brought up a kid super pure they'd just end up not getting on very well with all the pollution, probably more resilient if you let them suck in some toxins from a a young age.
Interesting that one of your kids worked on that tech!
Some think that older generations have more resistance and less allergies as we spent more time getting mucky as kids. Now it may be more about man-made toxins that we could have less natural resistance to. Ideally we should not be experimenting on ourselves like this.
