"The human body is largely not human. It contains trillions of microbes that outnumber out own cells 10 to 1, affecting our health and behavior. Now, an international consortium of around 200 scientists has mapped this diverse microbial community at an unprecedented level of detail, and shown just how much it varies from person to person. And microbe species that were shared across people still differed in terms of specific strains and genetic make-up of those strains. “Even when we carry the ‘same’ microbes, they seem to have small differences between their genomes just like people do,” - Todd Hoff from Bookmarklet
