Your belly button is overflowing with bacteria. In fact, there is so much bacteria in your belly button that you could be uniquely identified by the vomit-inducing ecosystem you’re harboring.
Scientists identified 2,368 species of bacteria after swabbing the navels of just 60 people, and 1,458 of the species “may be new to science.” And in the same study, one man was found to harbor bacterium that previously been found only in soil from Japan.
Pretty disgusting huh? Do you wash your hand everytime you touch your belly button or are you spreading those germs around?
