Today I watched a small child spill cheerios onto the floor of a public space and attempt to eat them. He managed to get three in his mouth before his mother arrived on the scene and put a stop to it.
I said, "No, this going to be great for his microbiome." I was about to tell her about the hygiene hypothesis, but then I realized that my opinion was about as welcome as a man knocking on your door to tell you about Jesus.
But I was rooting for that kid. I really wanted him to get that fourth cheerio.
