Why We Die: The New Science of Aging and the Quest for Immortality by Venki Ramakrishnan is a comprehensive exploration of the biological processes behind aging and death. The author, a Nobel Prize-winning molecular biologist, investigates the scientific understanding of aging, including how cellular processes, such as the degradation of telomeres, lead to the gradual cessation of cell replication and tissue regeneration. Throughout the book, Ramakrishnan emphasizes the societal implications of extending life and questions the ethics and practicality of immortality. While presenting scientific breakthroughs like the potential effects of calorie restriction and blood transfusions from younger individuals, the author remains skeptical about their applicability to humans. The book combines molecular biology with philosophical reflections on the meaning of life and death, offering a balanced, insightful perspective on aging and longevity
