Stiff: The Curious Lives of Human Cadavers

by Mary Roach

The way I see it, being dead is not terribly far off from being on a cruise ship. Most of your time is spent lying on your back. The brain has shut down. The flesh begins to soften. Nothing much new happens, and nothing is expected of you.

Death makes us helplessly polite.

Dissection and surgical instruction, like meat-eating, require a carefully maintained set of illusions and denial.

From the sixteenth century up until the passage of the Anatomy Act, in 1836, the only cadavers legally available for dissection in Britain were those of executed murderers.

Some anatomy instructors mined the timeless affinity of university students for late-night pranks by encouraging their enrollees to raid graveyards and provide bodies for the class. At certain Scottish schools, in the 1700s, the arrangement was more formal: Tuition, writes Ruth Richardson, could be paid in corpses rather than cash.

By and large, the dead aren’t very talented. They can’t play water polo, or lace up their boots, or maximize market share. They can’t tell a joke, and they can’t dance for beans. There is one thing dead people excel at. They’re very good at handling pain.

A falling human stops short when it hits the surface of the water, but its organs keep traveling for a fraction of a second longer, until they hit the wall of the body cavity, which by that point has started to rebound. The aorta often ruptures because part of it is fixed to the body cavity—and thus stops at the same time—while the other part, the part closest to the heart, hangs free and stops slightly later; the two parts wind up traveling in opposite directions and the resultant shear forces cause the vessel to snap.

“I lived for thirteen years in close contact with corpses,” reads the next line. One assumes that the teaching stint and the years spent living in close contact with corpses were one and the same, but who knows. Perhaps he kept dead family members in the cellar.

Today’s abdominal recovery surgeon is named Andy Posselt. He is holding an electric cauterizing wand, which looks like a cheap bank pen on a cord but functions like a scalpel. The wand both cuts and burns, so that as the incision is made, any vessels that are severed are simultaneously melted shut. The result is that there is a good deal less bleeding and a good deal more smoke and smell. It’s not a bad smell, but simply a seared-meat sort of smell. I want to ask Dr. Posselt whether he likes it, but I can’t bring myself to, so instead I ask whether he thinks it’s bad that I like the smell, which I don’t really, or maybe just a little. He replies that it is neither bad nor good, just morbid.

Placing the heart center stage in our definition of death served to give it, by proxy, a starring role in our definition of life and the soul, or spirit or self. It has long had this anyway, as evidenced by a hundred thousand love songs and sonnets and I bumper stickers.

The ancient Egyptians were the original heart guys. They believed that the ka resided in the heart. Ka was the essence of the person: spirit, intelligence, feelings and passions, humor, grudges, annoying television theme songs, all the things that make a person a person and not a nematode.

If you really wanted to know for sure that the human soul resides in the brain, you could cut off a man’s head and ask it. You would have to ask quickly, for the human brain cut off from its blood supply will slide into unconsciousness after ten or twelve seconds. You would, further, have to instruct the man to answer with blinks, for, having been divorced from his lungs, he can pull no air through his larynx and thus can no longer speak. But it could be done. And if the man seemed more or less the same individual he was before you cut off his head, perhaps a little less calm, then you would know that indeed the self is there in the brain.

If Demikhov had known more about immunology, his career might have gone quite differently. He might have realized that the brain enjoys what is known as “immunological privilege,” and can be kept alive on another body’s blood supply for weeks without rejection. Because it is protected by the blood brain barrier, it isn’t rejected the way other organs and tissues are.

I had heard Cleveland had undergone some sort of renaissance, but apparently it underwent it in some other part of town.

What’s nice about an alkali, as opposed to an acid, is that in doing the deed, the chemical renders itself inert and can be safely flushed down the drain.

The line between solid waste disposal and funerary rituals must be well maintained. Interestingly, this is one of the reasons the Environmental Protection Agency doesn’t regulate U.S. crematoria. For if it did regulate them, the rules would be promulgated under Section 129 of the Clean Air Act, which covers “Solid Waste Incinerators.” And that would mean, explained Fred Porter, of the EPA Emission Standards Division in Washington, “that what we’re incinerating at crematoria is ‘solid waste.’” The EPA does not wish to stand accused of calling America’s dead loved ones “solid waste.”
