GARM's Klotho Longevity Residency Brought 22 Participants to Honduras. Here's What They're Testing.
A four-day longevity residency at the Kimpton Grand Roatán included a proprietary Klotho intervention, blood sampling before and after, and researchers from MIT and Harvard. GARM is betting that Klotho is the next longevity biomarker to watch.
Peter Attia: High HDL Cholesterol Doesn't Protect Your Heart. It Might Hurt It.
HDL-C has been called 'good cholesterol' for decades. Peter Attia's latest analysis unpacks why the clinical evidence never supported the label — and why very high HDL-C levels may signal elevated cardiovascular risk, not lower.
Lung Cancer Screening for Never-Smokers: What the Data Says
Guidelines don't recommend lung cancer screening for never-smokers — but the evidence gap is a policy artifact, not a scientific finding. Peter Attia makes the case for personalized assessment.
