Your Microbiome Extends in a Microbial Cloud Around You, Like an Aura

"Your microbiome extends beyond yourself, into the air around you. It hovers in a cloud around your body and leaves bits of itself on surfaces wherever you go. In short, you have an aura, except it isn't made of purplish light; it's your personal cloud of dead skin cells, fungus and many, many microbes. And researchers are learning to be able to identify you by it."
