Hmm, most of us aren’t even aware of the existence of belly button fluff. But if you wiggle your finger inside your belly button (innies only) you might just catch a piece of fluff with your fingernail. Well, now it seems a chemist who has studied 503 (not 502 or 504 but 503) pieces of fluff from his own belly button for three friggin years has discovered that body hairs are the culprit behind the fluff. These hairs trap lint (from clothes), fat, dead skin, dust and sweat. All hail Georg Steinhauser (outstanding work).The good doc discovered that small pieces of fluff first form in the hair and then end up in the navel at the end of the day’. Ewh, the hairs act like barbed hooks that drag minuscule fibers into the belly button (wow). And this information helps us how? I want to know why on earth we have barbed hairs on our body dragging crap into our belly buttons? That can’t be good!
