The author uses serious facts and a sense of humor to tell the story of poop. The subject is crude, profane and vulgar. But it's also what all of us do mostly every day. The various chapters include everything you did and didn't want to know about fecal matters, the composition of poop; derivation of sh*t words; the history of poop; its uses; coprophagy; why it has various colors; types of stool; diarrhea and constipation; colonoscopy prep; poop as an embarrassment; semantics, idioms and sh*t as an expression; animal feces; the curious; personal hygiene and toilet paper; fake poop; synonyms; statistics and jokes. No photos. Not a medical reference manual. Just a lot to read about your favorite subject.
