In my opinion, most smells originate in body oders, or from what people eat and the way they live. People who eat a lot of fish will naturally smell fishy, and those who take garlic for their health will smell garlicky. So it's only natural that people who for millenniums neither practiced toilet training nor required toilet paper would smell like animals.
I will not go into the lives of the Canadian Indians or my life in Toronto here, although my story is related to the lives of about 100 people living in Toronto. That's because they all drink their own urine each morning.
For the past three and a half years (at this stage, I have been prancticing it for almost 35 years), I have drunk my own urine daily without fail. The reason is my chance encounter with an ethnic Indian in Toronto and the tremendous change in my health that resulted.
"Why should you drink urine? It's unthinkable. You'll get sick."
"This must be the end of the world. How can you even consider an outrageous idea like drinking urine when science has developed this far..."
"There's no way bodily excrement like urine can be good for you. Maybe animals drink urine, but humans don't need to because we're not four-legged creatures."
I can still hear these outraged rebuttals ringing in my ears. Questions and doubts gush forth one after another. Such quaestions are only natural. Indeed, I was not without such doubts and fears myself when I first began to drink urine.
