Five minutes of daily meditation can measurably lower a marker of inflammation and alter pathways in the gut microbiome. In this episode, Dr. Richard Davidson explains how exercise and meditation can work together to shape resilience and support the biology of flourishing. He also shows how meditation can be folded into exercise and ordinary routines, with benefits comparable to formal sit-down practice.

The next 10 years may add decades to human lifespan by compressing the time it takes to understand, treat, and prevent disease. In this episode, Dr. Derya Unutmaz explains why accelerating AI could transform drug discovery, shorten clinical trials, and push cancer treatment toward increasingly personalized interventions. He also reframes AI not as an existential threat, but as a medical enabler that doctors may soon be ethically obligated to use.

Many symptoms attributed to aging are also consistent with chronic inflammatory stress and impaired NAD metabolism. Dr. Charles Brenner explains the mechanisms, the human data, and what interventions actually move the needle.

One minute of vigorous exercise may be worth up to ten minutes of "moderate" cardio for extending lifespan and preventing chronic disease. In this Journal Club episode, Rhonda Patrick, PhD and endurance athlete Brady Holmer dissect a new Nature Communications study of more than 70,000 adults showing that vigorous intensity is roughly 4–10x more potent than moderate activity for reducing all-cause mortality, cardiovascular events, type 2 diabetes, and cancer outcomes—far beyond the long-standing 1:2 rule embedded in global exercise guidelines.

When testosterone runs low, libido isn't the only casualty—muscle mass drops, fat accumulates, insulin resistance rises, and motivation declines. In this episode, Derek from More Plates More Dates highlights common pitfalls that suppress testosterone and evaluates popular testosterone-boosting supplements like Tongkat Ali, boron, and ashwagandha, clarifying what's evidence-based versus overhyped. He also details practical strategies for testosterone replacement therapy (TRT), covering optimal delivery methods, benefits, risks, fertility implications, and key biomarkers to monitor.
