Podbit · The Peter Attia Drive
The causal chain from a Brazilian pit viper to captopril spans 70 years and five researchers across three continents, none of whom set out to develop a blood pressure drug. Each step answered only the question in front of it — and each answer unlocked the next.

By the late 1960s, the biochemistry of cholesterol synthesis was well understood, and every medicinal chemist in the field knew that inhibiting HMG-CoA reductase — the rate-limiting enzyme — should lower cholesterol. But nobody knew how to design such an inhibitor from scratch. Akira Endo at Sankyo in Tokyo took a different approach: instead of asking how to design an inhibitor, he asked who in nature had already designed one. [1] — Peter Attia "6,000+ microbial strains screened for statins: Akira Endo and Masao Kuroda screened more than 6,000 microbial strains over two years before…" 17:20 His reasoning was elegant. Fungi have been in chemical competition with bacteria for hundreds of millions of years. Many bacteria need sterols to build their cell membranes, so a fungus that could block bacterial sterol synthesis would have a lethal weapon. Penicillin was one such fungal weapon. An HMG-CoA reductase inhibitor could be another. Endo and his colleague Masao Kuroda screened over 6,000 microbial strains over two years before a strain of Penicillium citrinum from a Kyoto grain shop produced the hit they were looking for, in March 1972. Merck, working independently on a related compound from Aspergillus terreus, obtained FDA approval for lovastatin in 1987. [2] — Peter Attia "Lovastatin FDA approved 1987: Lovastatin, isolated by Merck from Aspergillus terreus and derived from Endo's original fungal finding, recei…" 18:10 From there came simvastatin, atorvastatin, rosuvastatin — the entire statin class that, by any reasonable estimate, has prevented millions of cardiovascular events and premature deaths. Peter notes that this is the cleanest example of a directed search for a natural solution: Endo had a hypothesis about where nature had already solved the problem, and he turned out to be right.
Akira Endo and Masao Kuroda screened more than 6,000 microbial strains over two years before finding the first fungal inhibitor of HMG-CoA reductase that led to statins.
Lovastatin, isolated by Merck from Aspergillus terreus and derived from Endo's original fungal finding, received FDA approval in 1987 as the first commercial statin.
Anxiety is not fear. Fear has an object — a wolf, a threat. Anxiety is the vertigo of standing at the edge of infinite possibility and knowing that choosing any one thing closes off all the others. Kierkegaard argued that the depth of your anxiety is proportional to the depth of your potential.
AI nailed Andrew Huberman's vertigo-vs-low-blood-pressure diagnosis because that pattern has been reported millions of times. But every patient's liver is different and data on liver surgeries is scarce worldwide — making solo robot surgery dangerous. The rule is simple: data abundance means AI can help; data scarcity means keep the human in the loop.
Fei-Fei Li's father had liver surgery performed by a da Vinci robot guided by a surgeon. The result: 10 times less blood loss than a typical procedure. This isn't replacement — it's the gold standard of human-machine collaboration, where the human's judgment and the robot's precision combine.
US drug overdose deaths fell from 110,000 to roughly 70,000 — the biggest CDC-recorded single-year drop ever. Men's rates fell 27% in one year, and the steepest decline of all was among 15–24-year-olds, down 37%. The crisis narrative around young men needs to make room for signs of genuine progress.
Kessler thought his grief expertise would protect him. It didn't. When his son David died unexpectedly, he found himself on the floor — and eventually realized that acceptance alone wasn't enough. That unmet need became the sixth stage: finding meaning.
Grief isn't just death — it's any unwanted change. Kessler lectured at Coca-Cola and General Mills not because they had lots of funerals, but because change management is grief management. People who grieve well live well.
Witnessing someone's grief isn't just emotional support — it's an essential act of healing. Kessler argues grief is a severance and connection heals it. But real witnessing has two steps: seeing the pain AND affirming the person's capacity to recover.
Avoiding grief isn't free — it's exhausting. Kessler's beach ball metaphor nails it: pushing a small balloon down is easy, but holding a massive beach ball underwater takes constant, draining energy. Unattended feelings don't disappear; they just consume you.
Most people try to control their environment to avoid triggers. Kessler flips this entirely: triggers aren't problems to manage around — they're a detailed map to your pain and your healing. Every trigger points directly to what needs attention.
