FOF 185 | John Linss. Maximizing Healthspan.

Today’s conversation goes beyond just how long we live, and dives into how well we live. We’re exploring the powerful idea of healthspan vs. lifespan, not just adding years to life, but adding life to those years. While lifespan measures total years lived, healthspan focuses on the years we remain healthy, active, and free from chronic disease. To unpack this, I’m joined by John Linss, founder of CoreSpeed Health, who’s working at the intersection of science, supplements, and real-world outcomes. In this episode, we’ll get into how John defines healthspan, and why he believes it matters more than simply living longer. We’ll explore what sparked his mission, the problem he’s solving with CoreSpeed Health, and his take on what’s broken in today’s wellness industry.
