Science Unlocks The Mystery Of Belly Button Lint 161

Posted by samzenpus from the extreme-navel-gazing dept.
After three years of research, including examining 503 pieces of fluff from his own belly button, Georg Steinhauser has discovered a type of body hair that traps stray pieces of lint and draws them into the navel. Dr Steinhauser's observations showed that "small pieces of fluff first form in the hair and then end up in the navel at the end of the day." Chemical analysis revealed the pieces of fluff were not just made up of cotton from clothing. Wrapped up in the lint were also flecks of dead skin, fat, sweat and dust. Unfortunately, further study has failed to yield a hair or fiber that would give Dr. Steinhauser the last three years of his life back.

          naval lint

          No, the study is on navel lint, the lint that accumulates in the navel. Naval lint would be the lint that accumulates on warships, or on members of the Navy. For instance, if you take the wetsuit of a SEAL and put it in the drier, and then clean out the lint trap, the result will be naval lint. Now, if you clean out the belly button of an Admiral, the result is naval navel lint. Or perhaps navel naval lint.

    • I learned women don't like it: I had a girlfriend, who first thing after we undressed and went to bed would look and pick out any navel lint from my "lint trap", as she called it. Things didn't happen until I had passed lint trap inspection.

      Special hair...
      Drawing debris into the intestinal area...
      Sounds a lot like a primitive sea creature, or even a carnivorous plant.

      I wonder if there's any shared evolution/genes here.

      • Actually a fantastic point. DNA does not specify the position of every cell within the body - there's not enough complexity there! Instead, it unfolds like a flower - and it can only unfold in so many ways. Why have we not evolved to have the belly button fade to a mere patch of scar over time? Why are sea anenomes shaped the way they are? The answer could be the same - if you tried to change it, something else would change too and you'd be some other organism.

    ie. Why is belly button fluff predominantly blue? I believe that the anatomical feature known as a 'navel' or 'belly button' is in actual fact a previously unrecognised organ that serves a vital role in the human body.

    As we all know, blood is red. Indeed the red colour of blood is integral to the role it plays in the body. I propose that the belly button is actually a chromatic lung which is capable of absorbing redness from the environment into the blood and similarly expelling excess blueness in order to maintain a healthy balance. This may be the reason that environments containing excess blueness cause people to feel cold: the blood looses redness, in turn diminishing it's oxygen carrying capacity leading to an overall reduction in the metabolism that actually serves to lower body temperature.

    Interestingly, there are reports that the navel fluff of aristocrats has a reddish hue, leading to speculation that they are in fact a distinct species. This has yet to be demonstrated under laboratory conditions and remains a controversial area of research.

      You may discover that there is a space-time/gravitational element to this conversation.

      That the blue or red shifting of belly button lint may have to do with a hidden element found in the lint that actually warps space-time, causing the observed red or blue shift in the local light as well as a possible secondary time dialation effect. Upcoming experiments with navel lint at Lawrence Livermore will soon determine if Belly Button Lint is the missing ingredient making Fusion a viable technology today.
