Episode notes
Prioritise Lifestyle Cornerstones
- Fix the fundamentals first: sleep, movement, diet, and environment before experimenting with drugs or supplements.
- Prioritise low-hanging lifestyle changes to reduce need for medications and supplements.
Be Cautious With Experimental Drugs
- Avoid early adoption of rapamycin or metformin unless older or at high immediate risk; evidence in humans remains limited.
- Wait for dog and human trial data to assess risk–benefit before personal use.
Avoid Hype-Driven Hacks
- Don't fall for hype around niche hacks like methylene blue unless you have mitochondrial dysfunction or a clear indication.
- Reserve synthetic interventions for relevant pathologies, not general use in healthy people.
