Summary
Aging is often described as damage, wear and tear, or inevitable decline. But what if aging is better understood as a problem of lost biological information ? In this episode of Galaxy Balance , Cory Smith speaks with Chris Bradley , a scientist focused on genome integrity and systems biology, about why maintaining genetic and epigenetic information may be central to extending human healthspan. The conversation explores how cells preserve. or fail to preserve, information over time, why DNA repair and genome stability may be underappreciated levers in aging, and what this framing implies for future interventions. We discuss how this information-theoretic view of biology reshapes how we think about longevity, why many aging strategies fail to scale, and what it would take to meaningfully slow or reverse age-related decline. Along the way, we examine the limits of current approaches, the tradeoffs between repair and replacement, and how first-principles thinking can clarify which longevity ideas are likely to matter long-term. This episode is a deep dive into aging as a systems problem, and what it would mean to preserve life’s information rather than simply treat its symptoms. Topics include: Aging as information loss vs. damage accumulation Genome integrity and DNA repair Epigenetics and biological memory Systems biology and scaling longevity interventions Constraints on extending human healthspan
