Abbreviated breast MRI takes 10–15 minutes versus 30–60 for a full exam, preserves nearly all the sensitivity, and cuts interval cancers in half for women with dense breasts — yet it remains almost completely absent from routine practice.

When mammography's sensitivity isn't enough — for high-risk women, women with dense breast tissue, or those who want maximum cancer detection — MRI is the strongest supplemental tool available. It uses magnetic fields and gadolinium-based intravenous contrast to detect abnormal blood flow and tissue behaviour, making it better than any other modality at finding small invasive tumours and atypical cancers. It's not a replacement for mammography — the latter still handles calcifications better — but it is used alongside it. The downsides are real: cost, access limitations, IV contrast, and a higher callback burden from its elevated sensitivity. But for women who can access it, the benefit is substantial. Adding MRI after a negative mammogram in women with extremely dense breasts cut interval cancer rates from 5 per 1,000 to 2.5 per 1,000 — a 50% reduction [2] — Peter Attia "MRI halves interval cancers in dense breasts: For women with extremely dense breasts, adding MRI after a negative mammogram cut interval ca…" 25:10 . The most significant and underutilised advance is the abbreviated MRI: a shortened protocol taking just 10–15 minutes compared to 30–60 for a full exam, while preserving nearly all the diagnostic sensitivity [1] — Peter Attia "Abbreviated MRI: 10–15 min vs 30–60 min: Abbreviated breast MRI preserves nearly all the sensitivity of a full MRI exam but takes only 10–1…" 24:15 . Attia calls it 'the most underutilized tool we have.' For situations where MRI isn't feasible, contrast-enhanced mammography (CEM) — introduced in 2011 and combining X-ray with iodine contrast — is the best alternative, though it remains less widely available.
Abbreviated breast MRI preserves nearly all the sensitivity of a full MRI exam but takes only 10–15 minutes versus 30–60 minutes, making it far more accessible.

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.
