About this piece
Humans have a ridiculous amount of archaea, bacteria, and fungi growing in and on them at all times. Some of them are beneficial, others harmful, and some can be either. They hang in a very delicate balance, and in so doing help your immune system fight other pathogens and break down and synthesize nutrients-- such as vitamin B and vitamin K-- that we can't on our own.
