Podbit · The Peter Attia Drive
The Women's Health Initiative in 2002 triggered a mass withdrawal of hormone replacement therapy from an entire generation of women. Those women, now in their 70s, may be experiencing higher rates of Alzheimer's disease as a direct consequence — a cohort-level outcome that Peter Attia and Gayatri Devi describe as a preventable tragedy.

A century and a half ago, most women died before menopause; today, they spend up to a third of their lives without estrogen — a hormone that drives synaptic sprouting in the hippocampus and is co-localized with memory systems. Barbara Sherwin's research at McGill demonstrated that surgical menopause triggers memory deficits, executive dysfunction, and word-finding problems that are clinically indistinguishable from early Alzheimer's disease [1] — Gayatri Devi "Estrogen loss at menopause drives measurable cognitive decline — including memory problems, word-finding difficulties, and executive dysfun…" 34:48 . Women also survive cardiovascular events at higher rates than men, accumulating shared risk factors for both stroke and Alzheimer's over longer lifespans. Immunological differences and possibly different hormonal vulnerability may also play roles. Gayatri Devi then introduces her concept of menopause-related cognitive impairment (MERCI), noting she has treated multiple women formally misdiagnosed with Alzheimer's who turned out to have a reversible hormonal condition.
Estrogen loss at menopause drives measurable cognitive decline — including memory problems, word-finding difficulties, and executive dysfunction — that is clinically indistinguishable from early Alzheimer's disease. Gayatri Devi has treated multiple women who were misdiagnosed with Alzheimer's when they actually had reversible menopause-related cognitive impairment.
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.
Running from pain doesn't leave it behind — it accelerates the chase. Whatever we run from pursues us, and whatever we face transforms us. Both Kessler and Lewis Howes testify to knowing both roads firsthand.
