Growth hormone: the youth hormone that may not lengthen life

Clinics offer growth hormone and drugs that release it to restore youthful muscle and skin, and Kyle Gillett and Craig Koniver describe using them, yet David Sinclair notes that lower growth signaling goes with longer life and Huberman lists the risks of injecting it. The contrast shows why feeling younger and living longer are not always the same goal.

AI agents at work: what changes when models act on their own

DHH runs parallel coding agents, the Cursor team describes agents working in a shadow workspace, Anthropic released a model that operates a computer, and Kokotajlo recounts a swarm that got out of hand. Moving from answering to acting multiplies both the usefulness and the risk.

Can a pill slow aging? Sinclair's optimism versus Attia's skepticism

Sinclair frames aging as a treatable disease and is bullish on resetting cellular age, while Attia's reviews of metformin and NAD boosters find the evidence much weaker than the hype. Seeing both views side by side helps readers judge whether expensive longevity compounds are worth their money yet.

Food first, supplements second, with one micronutrient caveat

Attia and Mosconi stress that supplements cannot make up for poor diet, sleep and exercise, while Rhonda Patrick argues that common deficiencies in magnesium, vitamin D and omega-3s are worth correcting directly. Together they suggest a sensible order: fix foundations, then fill documented gaps.

Hormones and longevity: menopause, optimization and where experts draw lines

Mosconi links menopause to women's Alzheimer's risk, while Attia and Koniver discuss hormone optimization as a longevity lever with differing enthusiasm. Midlife hormone changes turn out to matter well beyond fertility and deserve informed attention.
