it was amazing
bookshelves: non-fiction, traditionally-published, she-says, published2013

Mary Roach is an author I can always count on to deliver an amazing book. This time she tackles digestion.

Did you know that holy-water enemas were performed at exorcisms?!
If Jonah was really eaten by a whale, could he have survived?! What if it was a shark?!
What does your pet REALLY want to eat?!
What does it feel like to stick your arm into a fistulated cow's stomach?!
What does it feel like to get a colonoscopy without sedation!?
Is it possible to burst a human stomach?! Eat yourself to death by overfilling?!
Can constipation kill you!? Is that how Elvis died?!
She will explain SCIENTIFICALLY how dragon myths were invented.
Can you literally "knock the shit/beat the shit" out of someone!?

It's VERY interesting, you'll learn A LOT, and Mary Roach is - as always - funny, fresh, and fearless. She's a great author and a very entertaining one.

If you did read my status updates, you can see that at times this book can get pretty disgusting.
But there's also a lot of wonder and amazement and beauty in the book too. You will learn a lot and the world will make more sense to you after reading it.

Finally, I am going to mention some trigger warnings. I know there's a big debate right now over whether trigger warnings are just stupid and ineffective, but I think that if you are a survivor of any of the following: (view spoiler) you might want to proceed with caution in certain chapters. While Mary Roach approaches everything with a kind of scientific glee, seeing everything with a "that's so cool, and disgusting, but in an awesome fascinating way" glow that is very effective and friendly most of the time can leave me cold when she's talking about people's lives.

Oh, and ditto on the animals. This book is nowhere near close to the horrifying animal abuse presented in STIFF, but I want to warn those who are sensitive to animal cruelty that there are some experiments on dogs and other animals discussed here that are disgusting. Again, a far cry from STIFF, but still something worth mentioning.

In NO WAY to I feel like Mary Roach is making light of anyone (or any animal's) suffering. I think she's pretty respectful and I can understand why she put the stuff in the book. But it is a very graphic book and people who have been through some shit might want to skim or skip. That's all. It still gets a 5 from me.

P.S. And you might not want to read this book while you're eating.

3.16% "There are people, anorexics, so repulsed by the thought of food inside them that they cannot bring themselves to eat. - This is an interesting take on it I must say. My kneejerk reaction was to shoot this down, but on second thought, it's interesting. I wonder if she'll be exploring anorexia in this book."

7.18% "This perhaps explains how it was possible for a team of Canadian researchers to find 9 men and women willing to create a canned-cat-food flavor lexicon and a set of tasting protocols. For humans. Tasting cat food. And they couldn't be shy about it. The protocol for evaluating the "meat chunk" portion ("gravy gel having its own distinct protocol) stipulated that the sample be "moved around in the mouth and chewed..."

8.62% "Pet foods come in a variety of flavors because that's what we humans like, and we assume our pets like what we like. We have that wrong. "For cats especially," Moeller says, "change is often more difficult than monotony." (In reality, the average person eats no more than about 30 foods on a regular basis.

11.21% "I was surprised to learn that dogs lose interest when meat decays past a certain point. It is a myth that dogs will eat anything. "People think, dogs love things that are old, nasty, drug around in the dirt, Moeller told me earlier. But only to a point, he says. And for a reason. "Something that's just starting to decay still has full nutritional value.""

11.49% "...1/3 of the canned dog food purchased in housing projects was consumed by people. Not because they'd developed a taste for it, but because they couldn't afford a more expensive meat product...Alpo has more nutrition than sausage, fried chicken, shrimp, ham, sirloin steak, McDonald's hamburgers, peanut butter, pure-beef hot dogs, Spam, bacon, and bologna."

15.8% "To eat liver, knowing that you, too, have a liver, brushes up against the cannibalism taboo. The closer we are to a species, emotionally or phylogenetically, the more potent our horror at the prospect of tucking in, the more butchery feels like murder.

26.15% "A similar psychology applies to breast milk. It's considered natural for a child to consume a mother's milk, or even for a lover to do so, but not a stranger...so reliable is breast-milk consumption as a delimiter of intimate family that Islam recognizes a category called "breast milk son" which confers an exemption to the rules on segregation of the sexes."

"I believe human being has a destructive nature in its genes...human has a strange way of stress-release by punching, kicking, smashing, and other forms of destructive actions. Eating could be one of them.""
August 18, 2014 –
page 113
32.47% "Crispness and crunch appeal to us because they signal freshness. Old, rotting, mushy produce can make you ill. At the very least, it has lost much of its nutritional vim. So it makes sense that humans evolved a preference for crisp and crunchy foods."

47.7% "Here is another reason so many drug smugglers prefer to swallow contraband, despite the risk of an overdose. "The rectum is taboo across many of the regions where mules originate.
