Episode Details

Most men over 40 focus on lifting weights and dialing in their diet—but still overlook a major driver of long-term cardiovascular health.

In this episode, Ted speaks with Greg Mushen about why subsistence populations rarely develop heart disease, how walking influences glucose and lipid clearance, what genetics reveal about individual risk, and why daily movement may matter more than extreme workouts.

If the goal is to protect arteries, improve metabolic health, and age with resilience, this conversation offers a practical, research-driven framework worth listening to.
