For $89, Ubiome, a startup founded by Jessica Richman--a doctoral candidate at Oxford who did stints at Google and McKinsey after graduating from Stanford in 2009--will send you a kit that harvests the organisms that live inside your body. For additional fees, you can also gather bacteria from your mouth, nose, skin, and genitalia.
