There's millions of dollars in silver and gold hiding in poop
One of the fortunate results of modern sewage systems is that you don't have to use outhouses. One of the unfortunate results is that a bunch of precious metal winds up in the sewage, incapable of being put to good use.
Scientists presenting to the American Chemical Society last year said that there are tiny fragments of metal everywhere -- beauty products, deodorant, even socks -- that wind up literally flushed down the drain. Metals like gold, silver, platinum, and everyone's favorite, vanadium, are present in commercially viable amounts in poop. One estimate calculated that the shit of 1 million Americans may contain $13 million in metal. All someone has to do is go get it.
Even if you don't eat, you'll still poop
Sure, some foods make you poop more than others, and it can take on the color and texture of your latest meal. But even if you don't eat anything, you'll still need to take a dump. That's because poo is made up of more than just the food you ingest.
"If you don’t eat, you can still have feces because the body produces secretions. Juices from the pancreas, intestinal lining, bile, gastric juices, all those juices are mixed together, that produces the liquid stool that empties from the small bowel into the colon, which is the large bowel," Dr. Shah says. "And the large bowel’s function is to absorb all the water from the feces. That’s why the feces that comes out of the rectum is really solid."
