Science has given us a lot. Cars; toasters; bombs; the elimination of smallpox, polio and God; the etch-a-sketch. But there is (or was) one question science cannot (or could not) fathom: "
What is all this crap in my belly button?"

Now, Austrian chemist
Georg Steinhauser believes he has the answer:
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."
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.
Hmmm. Is this a "journalist brightens slow news day with off-the-wall science story" story, or is it a "scientist claims to make amazing discovery when actually we kinda guessed it already" story? I'm not quite sure.
Ah, well. At least there's still toe cheese. Even science would never dare try to explain
that!
