How many mites do you have?

Demodex mites, or follicle mites, live in human skin. By some estimates, you have a colony of 1,000 to 2,000 living in your skin right now. When you touch someone or share fabrics with them, you're trading follicle mites. Unless you touch someone's heart, in which case you don't give them follicle mites, but a warm fuzzy feeling inside. It's a figure of speech, you see.
