Why We Die: The New Science of Aging and the Quest for Immortality

Nobel laureate Venki Ramakrishnan examines the biological mechanisms that dictate why humans age and eventually fail. The narrative tracks how cellular processes—including DNA damage, protein accumulation, and the shortening of telomeres—contribute to physical decline. Ramakrishnan details the work of researchers attempting to bypass these natural limits using tools like senolytics to clear aged cells and epigenetic reprogramming to reset cellular identity. He evaluates the scientific validity of current anti-aging interventions, separating chemical realities from the speculative claims of the longevity industry while addressing the energetic costs of being alive.

This book serves readers interested in molecular biology and the practical limits of life extension. It appeals to those who want a technical explanation of aging rather than generic health advice. Readers gain a clear understanding of why immortality remains biologically elusive and learn to distinguish between evidence-based gerontology and commercial hype. The text provides a realistic framework for thinking about the trade-offs between reproduction, growth, and repair, leaving the reader with a grounded perspective on the inevitable cycle of biological decay.
