Roach frequently juxtaposes historical medical failures with modern technological attempts. Analyze how this structural choice functions throughout Replaceable You. How does placing ancient Indian forehead flaps alongside modern skin grafts, or 19th-century milk transfusions next to ECMO, shape the book’s core theme that progress is non-linear?

Using the examples of joint replacement materials, artificial sphincters, and the tear film, analyze how Roach develops the argument for the body as superior to replacements. How does her focus on both large-scale mechanical failures and microscopic biological complexity create a comprehensive critique of engineering-based solutions?

Examine the theme of patient autonomy in Replaceable You through the stories of Judy Berna’s elective amputation and Dr. Garcia’s transgender surgery patients. How do these narratives critique medical paternalism and redefine the concept of a successful surgical outcome from the patient’s perspective rather than the surgeon’s?

How does Replaceable You engage with or subvert the conventions of the popular science genre, which often presents science as a story of heroic discovery and inevitable progress?

The narrative features several portraits of “maverick innovators” like Dr. Bartlett, Dr. Garcia, and Dr. Kuzanov. Analyze Roach’s characterization of these figures. How does she subvert the conventional portrait of straightforward scientific heroes?

Roach travels from a burn unit in Massachusetts to xenotransplantation labs in China and a surgical clinic in Mexico City. How do her characterizations of these distinct global settings contribute to her analysis of medical innovation? Discuss how each location reveals different cultural, economic, or ethical forces shaping the quest to replace the human body.

Analyze the rhetorical effect of the Epilogue that concludes the book. How does it contribute to or push back against the arguments that Roach makes throughout the text?

Throughout the book, Roach employs unexpected analogies to explain complex science, comparing orthopedic surgery to woodworking and a cell culture lab to a kindergarten. Select two of these extended metaphors and analyze their function. How do these comparisons serve to demystify medicine while simultaneously reinforcing the book’s central themes?
