The wine flavors “leather” and “horse sweat” are tells for the spoilage yeast Brettanomyces.”

— Mary Roach

I asked Chen what might lie behind this seemingly universal drive to crunch things in our mouths. “I believe human being has a destructive nature in its genes,” he answered. “Human has a strange way of stress-release by punching, kicking, smashing, or other forms of destructive actions. Eating could be one of them. The action of teeth crushing food is a destructive process, and we receive pleasure from that, or become de-stressed.”

— Mary Roach

145. “Unlike filets and stewing meats, organs look like what they are: body parts. That’s another reason we resist them. “Organs,” says Rozin, “remind us of what we have in common with animals.” In the same way a corpse spawns thoughts of mortality, tongues and tripe send an unwelcome message: you too are an organism, a chewing, digesting sack of guts.”

— Mary Roach

146. “The anonymity of body parts facilitates the necessary dissociations of cadaveric research: This is not a person. This is just tissue. It has no feelings, and no one has feelings for it. It’s okay to do things to it which, were it a sentient being, would constitute torture.”

147. “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.

Like most creatures that swallow their food whole, sperm whales have a limited-to-nonexistent sense of taste. The photo is a black-and-white still life of twenty-five objects recovered from sperm whale stomachs. It’s like Jonah set up housekeeping: a pitcher, a cup, a tube of toothpaste, a strainer, a wastebasket, a shoe, a decorative figurine.”
