Radical Life Extension

Aging is the leading cause of death, yet it remains largely unchallenged. Radical Life Extension confronts it directly, exploring three parallel strategies: biostasis, which preserves the body after death; replacement, which restores function through new tissues and organs; and advanced bioengineering, which produces therapies to slow and reverse aging.

Cutting through hype and false promises, this book explains why most longevity strategies fall short, which approaches have a real chance of success, and what it will take to turn possibility into reality. It offers a clear, technically grounded view of the science, along with a practical answer to a pressing question: how can individuals help bring about a future without aging.
