For millennia, humanity has sought the secret to defying death. Only in recent decades, however, have we begun to unravel the complexities of aging, and conceived plausible technology paths to solving it.

Immortality or Death is a celebration of the remarkable strides made in aging research. This book offers a profound, comprehensive, and meticulously detailed exploration of our current understanding of aging, alongside the most advanced efforts to slow it down. With a critical eye, it debunks the allure of modern biohacking—the “false grail”—and shines a spotlight on the most promising scientific directions. Drawing on the systematization of over a thousand studies and research articles, Immortality or Death provides a balanced perspective, including healthy skepticism of pseudoscientific claims and optimism inspired by real scientific progress.

Beyond its scientific depth, Immortality or Death is an ode to human life itself, challenging the outdated notion that the pursuit of immortality or agelessness is the domain of mad tyrants or unethical scientists. The book champions this quest as a noble and deeply human endeavor, rooted in compassion and curiosity. Finally, it outlines both a scientific roadmap and social strategies to accelerate progress in humanity's ongoing battle against the injustice of death, encouraging readers to imagine a future where aging is no longer inevitable.
