There’s an interesting article in Nature on the human microbiota — “the vast population of microorganisms that live in and on the human body.” I’m not sure I can think of a theological angle at the moment, but this description is oddly compelling:
An infant’s first exposure to microbes is at birth, as it slides out of the sterile womb, slurping up and smearing itself with its mother’s vaginal fluids and faeces. From then on, life is one long microbial onslaught. New bacteria, viruses and fungi colonize every exposed organ — skin, eyes, lungs, gastrointestinal (GI) tract.
Makes you think a bit differently about that face in the mirror: a walking, talking universe of germs. Yum!
