What if you could live not just longer, but healthier—and possibly forever? In his groundbreaking exploration of biotechnology, ethics, and the philosophy of very long lives, Thomas Ramge takes readers on a thought-provoking journey through the possibilities and consequences of radical life extension. Drawing on cutting-edge research in molecular biology, genetics, and AI-driven medicine, the book examines how humanity is on the brink of a revolution—one where aging may soon become a treatable condition. Through engaging thought experiments, such as choosing between three pills that extend life to 100, 200, or eternity, the book challenges our assumptions about mortality, identity, and purpose. Would centuries of life bring wisdom or existential despair? Could societies sustain themselves in a world where death is optional? And who would have access to these medical breakthroughs—everyone, or only the wealthy elite? Combining scientific rigor with philosophical depth, this book is a must-read for those fascinated by the intersection of technology, ethics, and the human condition. If the future of life itself is at stake, what will we choose?
