We already know that belly buttons are gross. But now, thanks to a lengthy survey of human navels, we know that they're really gross. Not only do they hold lint and all sorts of other shit, but they're bacteria-filled pits of filth. Researchers from NC State University have analyzed 95 navel samples so far, which contained some 1,400 bacterial strains. Ugh. And, as The Washington Post notes:
In 662 cases, the microbes could not even be classified to a family, "which strongly suggests that they are new to science," says team leader Jiri Hulcr of North Carolina State University in Raleigh.
