As we have learned more about ourselves and the universe in which we live, we have relatively recently learned that while the human body is made up of roughly 10 trillion cells, there are roughly 100 trillion one-celled organisms, bacteria and fungi, living in and on us. Ten times as many of their cells as ours.

Knowing this, could and should change one’s life.

If it doesn’t jump out at you, at least, consider what they eat, and who’s feeding them.
