This debate brings together leading voices in longevity to separate evidence from speculation. They discuss why misinformation is growing and why many people chase advanced treatments before addressing basic health.

The panel explores longevity escape velocity, healthspan versus lifespan, and how much progress has actually been made. They debate whether dramatic life extension is near or still much farther away than many believe.

The conversation also examines peptides, NAD+ infusions, longevity clinics, and biological age tests. Along the way, they discuss risk, regulation, incentives, and how to distinguish credible medicine from marketing.
