Losick poses the question “Are we more microbial than human?”  There are 10 times more bacterial cells on and in us, the human microbiome, than human cells and 100 times more types of bacterial genes than human genes.  These bacteria certainly influence our health, and Losick wonders if they also might influence our behavior.
