Found: The source of … belly-button lint

A chemist in Vienna has taken the term “navel gazing” to its logical extreme and guaranteed himself a curious epitaph: Unraveler of the mysteries of belly-button lint.

Georg Steinhauser discovered that there is a certain type of body hair responsible for directing lint into the navel. The researcher spent three years studying 503 pieces of schmutz from his own belly button, then published his conclusions in the journal Medical Hypotheses under the title, “The nature of navel fluff.”

Among other gems, the article notes: “Accordingly, and to the author’s personal experience, navel lint seems to be a phenomenon that affects primarily male adults.”

Steinhauser found that hairs around the belly button have a scaly structure that pulls fibers from clothing and then directs those fibers—along with dead skin, fat, sweat and dust—into the belly button.
