How to be a "Super Ager" (it's not your genes)

In this episode of the TED Radio Hour, host Manoush Zomorodi explores the science of becoming a 'super ager'—someone who lives well into old age without major age-related diseases like cancer, heart disease, or Alzheimer's. Dr. Eric Topol, cardiologist and author of *Super Agers*, reveals that genetics play a surprisingly small role in healthy aging. Instead, lifestyle choices, immune system health, and cutting-edge technologies like AI and omics (genomics, proteomics, epigenetics) are the real keys to extending health span. Topol shares groundbreaking findings: the shingles vaccine reduces Alzheimer's risk by 20–25%, and a healthy thymus gland in adulthood correlates with lower cancer and heart disease rates. He emphasizes that prevention, not just treatment, is now possible with AI-powered tools that can predict disease decades in advance. Despite the promise of medical advances, Topol warns against pseudoscience—like unregulated peptides and protein supplements—while urging individuals to demand personalized, evidence-based care. The episode ends on an empowering note: it's never too late to change your aging trajectory through science-backed habits and proactive health management.
