He talks about eating earthworms as a kid.
Of course, it turns out, biologically speaking, that big, dirty earth-muncher probably did my immune system, my intestinal tract and all the happy bacteria therein a world of good. It's true.Furthermore he says
we as an overpampered culture are probably not getting enough nasty buggy immune-system-boosting microbes in our diet, in our meats, in our mouths. And therefore we should probably, you know, eat a bit more crap.I am not sure I would go as far as suggesting eating crap, but I second the notion that we as a society have to stop being obsessed with getting rid of all bacteria. Bacteria are overall good.
