Ear cartilage is similarly underserved by the vascular system, so if you plan on picking a fight with Mike Tyson, do practice good wound toilet.)

The pole is nonconductive, enabling the savvy rescuer to save a life without joining the growing conga line of electrocution victims.

They live like rice, too, pressed together: a moist, solid entity. If you lower your head to within a foot or two of an infested corpse (and this I truly don't recommend), you can hear them feeding. Arpad pinpoints the sound: "Rice Krispies." Ron frowns. Ron used to like Rice Krispies.

Sometimes courage is nothing more than a willingness to think differently than those around you. In a

Albert Ken-rich Fisher's 1900 "Summary of the Contents of 255 Stomachs of the Screech Owl" made me feel tired and sad, though also vaguely festive, owing to the author's "Twelve Days of Christmas"–style presentation: "91 stomachs contained mice … 100 stomachs contained insects … 9 stomachs contained crawfish … 2 stomachs contained scorpions …" Droppings provided a kinder, less taxing alternative.

Taste, like smell, is a doorman for the digestive tract, a chemical scan for possibly dangerous (bitter, sour) elements and desirable (salty, sweet) nutrients.

We gave Mrs. Peterson some shit for her quinsy and now she's doing fine!

What's the main ingredient in AFB's dog-food palatants? "Liver," says Moeller. "Mixed with some other viscera. The first part that a wild animal usually eats in its kill is the liver and stomach, the GI tract." Organs in general are among the most nutritionally giving foods on Earth.

there's a good chance St. Martin was happier in his simple shack with his family, "perfectly necket," than Beaumont was toiling in his labs, misunderstood by his colleagues. To each his own. Beaumont was a man for whom career came first. Like any experimenter, he was meticulous and exacting. People are messy, unpredictable things. Science you can control. Which is why St. Martin was such a bugbear for Beaumont.

if you slip a rat's face and hide, Hannibal Lecter–style, over the snout of a non-favored prey item, a python will try to swallow it. (University of Alabama snake digestion expert Stephen Secor did this some years back to reenact a scene for National Geographic television. "Worked like a charm," he told me. "I can get a python to eat a beer bottle if I put a rat head on it.") For

Funny thing happened on the way to the moon: not much," wrote Apollo 17 astronaut Gene Cernan. "Should have brought some crossword puzzles.

What sets a professional nose apart from an everyday nose is not so much its sensitivity to the many aromas in a food or drink, but the ability to tease them apart and identify them.

Animals have evolved to survive," Rawson says. They like what's best for them. People blanch to see "fish meal" or "meat meal" on a pet-food ingredient panel, but meal—which variously includes organs, heads, skin, and bones—most closely resembles the diet of dogs and cats in the wild.

Here is what William Beaumont had to say about saliva: "Its legitimate and only use, in my opinion, is to lubricate the food to facilitate the passage of the bolus through the [esophagus]." Beaumont was right about some things, but he was dead wrong about spit.

Rawson has an idea of what it is like to eat without perceiving tastes, because she has talked to cancer patients whose taste receptors have been destroyed by radiation treatments. The situation is well beyond unpleasant. "Your body is saying, 'It's not food, it's cardboard,' and it won't let you swallow. No matter how much you tell your brain that you need to eat to survive, you'll gag. These people can actually die of starvation.

As hunters and foragers of the dry savannah, our earliest forebears evolved a taste for important but scarce nutrients: salt and high-energy fats and sugars.

SHOULD CIRCUMSTANCE PREVENT a man from carrying his cigarettes and cell phone in his pants pocket, the rectum provides a workable alternative. So workable that well over a thousand pounds of tobacco and hundreds of cell phones are rectally smuggled into California state prisons each year. The contraband allows incarcerated gang members and narcotics dealers to make business calls from behind bars (and to enjoy a smoke while doing so).

This is a book about notable achievements made while dead.

technologists sometimes exploit the synergy between the two. By adding strawberry or vanilla—aromas we associate with sweetness—it's possible to fool people into thinking a food is sweeter than it really is. Though sneaky, this is not necessarily bad, because it means the product can contain less added sugar. Which

What can be done for these men? A lot. The art of phalloplasty—crafting a working penis from other parts of a patient's body—has come a long way (thanks in no small part to the transgender community).

dogs rely more on smell than taste in making choices about what to eat and how vigorously. (Pat Moeller estimates that for dogs, the ratio for how much aroma matters to how much taste matters is 70/30. For cats, the ratio is more like 50/50.)

Could those sound waves shake apart your organs? NASA did testing on this back in the sixties, to be sure, as one infrasound expert told me, "that they didn't deliver jam to the moon.

They think of it as lubricating, and that's it!" She went back to her hotel room and called her boyfriend in tears.

According to the Kind & Knox Web site, other products made with cow-bone-and-pigskin-based gelatin include marshmallows, nougat-type candy bar fillings, liquorice, Gummi Bears, caramels, sports drinks, butter, ice cream, vitamin gel caps, suppositories, and that distasteful whitish peel on the outside of salamis.
