In this episode, biohacker and content creator Siim Land joins Dr. Matt Kaeberlein for a wide-ranging discussion on optimizing health span, longevity science, and the balance between personal experimentation and evidence-based strategies.

Key Points:

Siim Land shares his personal health journey and philosophy, highlighting the importance of foundational habits—like sleep, diet, exercise, and social connection—in extending health span. The conversation explores hype vs. science in longevity, misinformation challenges, and responsible communication in the wellness space.

• Defining Longevity- Health Span > Lifespan: Siim emphasizes that real-world longevity today focuses more on maintaining health and functionality rather than extending maximum lifespan—adding quality years, not just quantity.
• Skepticism Around Longevity Escape Velocity: Both guests critique the notion that humans are close to escaping ageing through tech or drugs. They stress the lack of current data and call for realistic expectations based on science, not hype.
• The Danger of Misinformation in Health Media: They discuss the rise of influencer-driven longevity advice, warning against cherry-picked science and overpromised protocols. The pair call for clearer, more responsible health communication.
• Tracking What Matters: Biomarkers & Biological Age: Siim discusses his use of tools like DEXA scans and blood markers (e.g., CRP, ApoB, HbA1c) over biological age clocks, which he now views as too noisy and unproven for real health guidance.
• Lifestyle Wins: Exercise, Nutrition, and Sleep: Regular resistance and cardio training, a moderate-to-high-fibre whole food diet, consistent sleep, and limited alcohol intake are cornerstones of Siim’s health philosophy—proven to improve health span.
• Social and Psychological Wellbeing: The importance of human connection, purpose, and emotional grounding are highlighted as essential yet underrated components of longevity and healthy living.
