A lively, illustrated journey through the science of prosthetics, transplants, and regeneration—where the boundaries between human and machine blur and medicine redefines what “you” can be.
What happens when science starts making spare parts for people? Replaceable You is a curious, human tour through the frontier of modern medicine—where limbs, organs, and nerves meet engineering, robotics, and ethics. With humor, wonder, and clarity, it explores the scientific breakthroughs that blur the line between natural and artificial life.
The story begins in a quiet prosthetics lab where carbon fiber legs are adjusted with a wrench. Then it moves into operating rooms where surgeons perform face transplants and reattach hands that were once lost. From there, the book dives into a beating-heart operating theater, a tissue regeneration lab, and a workshop where synthetic skin grows under LED light.
