I've been obsessed in recent months about the connections between our gut bacteria and food allergies, asthma, eczema, even autism. The research coming out about being too clean, and too sanitized, is fascinating, and there's a whole subcategory of this research about dairy (which I personally react to in various ways) and skin/digestive/bacterial issues. The superbugs and fecal transplants and microscopic curing of insane food allergies in children... this stuff is the Best. If I was fifteen, I really might go into medicine or biology; that's how much this fascinates me.
But. There's a line. My great-grandmother said we all have to eat a bushel of dirt before we die, and she was right, no doubt. But this article about changing stations that are never cleaned, and the norovirus that brought down most of the employees of an auto dealership after a little kiddo had an epic, explosive shit situation in their bathroom... that's the line. That's too much dirt. That was enough to make me want to use Purel! And the force of nature no further can go.
