..that's the usual advice when folks hear that
you are visiting some "country where they have dirty water".
Don't drink the water..it's full of "bugs and stuff".
..got news for all them smug folks in Amerika.
Your fine treated and chlorinated "safe "drinking water" is
full of stuff that make garden variety bacteria look
harmless as parakeets.
Water system full of particles that grow all manner of fibers. Particles get into the human machinery..them
particles will sprout fibers all over the body..inside
~20x fov~ 10 mm
...that fake hair looks a lot like the fibers in the water
[purely coincidence of course..]
Of course none of this is real. It's all in your head.
Imaginary. Like leprechauns and elves and such.
??dang if I know how imaginary stuff can be photographed..but maybe some folks imagination is stronger
