In 'Tales From Djakatar' by Pramoedya a Ananta Toer, there is a conversation between a Houseboy and a Maid which goes "How simple life is. It's as simple as this: you're hungry and you eat, you're full and you shit. Between eating and shitting, that's where human life is found." Kathleen Meyer's book gives the first two stages of life a miss and concentrates solely on the last in the trinity of simple life stages namely defecating. More precisely how to rid the body of it's intake of food and liquids whilst in the great outdoors without causing an environmental 'tsunami' or debasing one's apparel or filling up one's boots to overflowing.
Whilst the toilet humour aspect of the book might well have made a major contribution to it becoming "The International Best-Seller With Over 1 Million Copies Sold", the book is not merely a comedic escapade into outdoor toilets. It is a very conservation orientated work of helpful hints for causing the absolute minimum impact on our fragile environment in pursuit of the ultimate and possibly overwhelmingly pressing objective of bowel and bladder relief. Interwoven into the narration and advice is the most comprehensive collection of information possibly to be found on the subject of crap, as well as a veritable treasure trove of useful gadgets, and the 'bottom' line facts about the effects of excrement on the land and water.
This book when left prominently on your coffee table will soon cause either great hilarity or acute embarrassment among your guests, far more than the latest copy of 'Harry Potter' or similar, but either way it will solicit a reaction, that should lead to a fruitful and enlightening conversation on this most fundamental of all human bodily needs.
