Ageless

Andrew Steele is a computational biologist who decided to spend his career on what he sees as the root cause of nearly all human suffering: aging itself. The science here is genuinely exciting — clear explanations of senescent cells, DNA repair, mitochondrial decline, and the experimental therapies targeting each. Steele is an enthusiastic and credible guide, and he makes complex biology feel urgent rather than academic. The honest caveat is that the final chapter on what you can do right now feels thin, almost bolted on after hundreds of pages of laboratory promise. Readers who hold strong convictions about the natural limits and meaning of human life will also find the secular-materialist worldview goes unexamined. For anyone curious about where aging science is headed, this is a genuinely illuminating read.
