This Four Corners documentary investigates the booming longevity industry, exploring the gap between consumer health trends and scientific evidence. Reporter Dr. Norman Swan examines the risks when the desire to slow aging is met with unregulated or unproven business practices.
Key areas explored:
- The Biohacking Industry: The documentary visits the Biohackers World Conference in New York () and Next Health clinics in Los Angeles (), highlighting common treatments like IV drips, full-body MRIs, and plasma exchange. Experts warn that many of these are expensive and lack robust clinical evidence ().
- Regulatory Gaps in Australia: The investigation finds a rapidly growing Australian industry offering unapproved peptides (). Laboratory testing commissioned by Four Corners revealed that some online-purchased peptides contained incorrect dosages or harmful contaminants ().
- The Science of Aging: Moving away from commercial clinics, the documentary looks at legitimate research in San Francisco () and Boston (). Scientists like Dr. David Sinclair are researching partial epigenetic reprogramming (), while others explore thymus regeneration () and the use of biological age clocks to measure the effectiveness of interventions ().
- Lifestyle Foundations: Experts emphasize that established scientific methods for healthy aging—specifically a plant-forward, nutrient-dense diet and regular exercise—remain the most effective and proven interventions ().
