About This Book

Book Summary

From the New York Times bestselling author of Stiff and Fuzz, a rollicking exploration of the quest to re-create the impossible complexities of human anatomy.

The body is the most complex machine in the world, and the only one for which you cannot get a replacement part from the manufacturer. For centuries, medicine has reached for what's available―sculpting noses from brass, borrowing skin from frogs and hearts from pigs, crafting eye parts from jet canopies, and breasts from petroleum by-products.

In Replaceable You, Mary Roach sets sail on the uncharted waters of regenerative medicine, exploring the remarkable advances and difficult questions prompted by the human body's failings. When and how does a person decide they'd be better off with a prosthetic than their existing limb? Is there a sensitive way to harvest tissue and bones from the deceased? Which animals might be the best organ donors? Through interviews with patients, physicians, pathologists, engineers, and scientists, Roach immerses readers in the wondrous, improbable, and surreal quest to build a new you.

...ut. Changing genres I started The Correspondent. Wasn't sure I would like the format of all letters but it grabbed my interest. Alternating that with Replaceable You by Mary Roach. Fascinating study of history of creating spare or replacement parts for the human body

BookBrowse

The book is more than just a simplified explanation of procedures. Roach combines all this medical minutia with healthy doses of history and trivia. (Did you know that in 600 BCE, "the Vedic surgeon Sushruta reconstructed noses from a plot of adjacent facial skin," making rhinoplasty "the original plastic surgery"?) We learn about pioneers in the various medical and scientific fields related to anatomical replacements, as well as early efforts at repairing the human body...continued

Media Reviews

BookPage
Readers will feel awe at all the body can do and how it is made, as well as admiration for humanity's per­sistence in exploring its limits—whether when confronted with a malfunctioning organ or the desire for a more plump derriere. Replaceable You will delight Roach's fans and surely garner some more.

The New York Times
Since she burst onto the scene with 2003's Stiff: The Curious Lives of Human Cadavers, the science writer Mary Roach has been grossing readers out with curiosity, humanity — and alarming gusto. And we can't look away.

Wall Street Journal
Replaceable You by turns surprises and delights, revealing information that even I didn't know…These curious facts, with attendant and laugh-inducing footnotes, keep us turning the pages, but the real power of the book lies in its humanity.

Kirkus Review (starred review)
An amiably entertaining, endlessly intriguing stroll through the stuff of which we're made.

Author Blurb Daniel Kraus, author of Whale Fall
Mary Roach has had a more direct impact on my career than any other writer. She is her own genre of book―gonzo, hilarious, wildly educational. This is Roach at her finest.

Author Blurb Deborah Blum, best-selling author of The Poisoner's Handbook
In her brilliant (and brilliantly funny book) Replaceable You, Mary Roach explores the puzzle of the human body, the way we can assemble and reassemble the very human pieces into different versions of who we are and how we work. The result is intriguing, compassionate, wise and―as with all her books―addictively readable. Or to put this another way: Don't miss it.

Beyond the Book



Mrs. Chase, Medical Manikin

A manikin of a woman's lower body giving birth In Replaceable You, author Mary Roach talks about the use of medical manikins—lifelike practice dummies—in training doctors and surgeons. These manikins are designed to replicate human anatomy and physiology realistically, so that healthcare professionals can refine their skills in a controlled environment. As medical science has progressed over the years, so too has the complexity of manikins available to train up-and-coming physicians.

Before the turn of the 18th century, human figures were widely used in medicine across many cultures. Anatomically correct doll-sized models were made of clay as a way to illustrate the placement of human organs and the effects of various diseases on the human body. These were ...
