“I've lost close family members to cancer that didn't yet have treatments available, the hardest part for them wasn't affording it. A lack of innovation is access problem we often overlook because it isn't as salient-but it is a far larger barrier than price.” - @C_Garthwaite

Also: conclusion of NYT piece especially critical, speaking to value of participation in "Greysteel" as fostering a sense of community+purpose-so much more than simply performance metrics that so many seem obsessed with optimizing -> timmermanreport.com/2025/06/from-o…. @SS_strength

This @nytimes story about "older" (>40y) people lifting is wonderful (and a brilliant idea) - and I guess @SS_strength's secret is out, as Dr. J. Sullivan's book "The Barbell Prescription" has been shared for years like samizdat among enthusiasts... nytimes.com/2025/07/26/wel…

In contrast to evanescent wellness "trends," lifestyle interventions striving to improve health by helping movement, sleep, and strength are backed by considerable, robust data; here's a slide from a recent talk I gave that's about strength. cc @SS_strength

Paradox also highlighted recently by @pmarca on @a16z pcast, as I discussed in @timmermanreport -> timmermanreport.com/2025/02/the-fu… cc @zakkohane @sapinker @emollick @vijaypande

Brought to my attention by @NathanPriceSci & Lee Hood’s book (“Age of Scientific Wellness “), specifically when Hood discussing initial widespread resistance of scientific community (including @NIH) to HGP; tide changed he said when assoc tools perceived to be broadly useful

One more slide from my talk, abt data demonstrating virtuous cycle betw physical activity+purpose. I've argued this "agentic dividend" can also be used to motivate other health-promoting activities (from improving your sleep to not deferring that colonoscopy...) @GretchenReynold

One point to emerge from this is the continued relevance of "Miles' Law" - "where you stand depends upon where you sit..." - both D & R folks react incredibly differently to similar news/events based on whether D or R is in office, apparently. @pmarca @bhorowitz @bariweiss

This is fascinating @a16z pcast in which @pmarca & @bhorowitz provide their view of the radical changes in the media environment. It was the first time I ever heard something like totality of their perspective; I found it interesting - YMMV. @bariweiss podcasts.apple.com/us/podcast/new…

We're in a bad place with the amount of anti-Jewish content being put out daily. Luckily, the evidence doesn't go away for these low IQ humans. To my Jewish peeps, let the haters hate. Strive to be great and keep succeeding in life. Don't let the weak minded bring you down.✡️💪

Illustrative timely eg of how the peptide wellness craze is viewed by leading scientist (@EricTopol) focused on …the science open.substack.com/pub/erictopol/… & leading fitness & wellness site, @fittinsider that details what industry players actually doing: insider.fitt.co/issue-no-345-p…

Also, @mariojoze, there's a fascinating interview with founder of @slingshotai_inc on @AndrewYang's podcast -> podcasts.apple.com/us/podcast/thi…. Plus for those who missed link to your new @statnews on @slingshotai_inc -> statnews.com/2025/07/22/sli…

You are right, @mariojoze, linkedin.com/posts/mario-ag… oppys at intersection of mental health+(carefully trained) genAI haven't escaped our notice! I explicitly cited @slingshotai_inc also @LoreHealth in @timmermanreport here timmermanreport.com/2025/06/from-o… & timmermanreport.com/2025/07/person… ...

This is the new Harlem shake, incredible

Honestly if i read one more fucking LinkedIn post with the same ChatGPT-inspired "It's not A. It's B." construction ....

Essential read (erictopol.substack.com/p/the-peptide-…) from @EricTopol and pairs nicely with a recent, detailed (of course) piece he wrote on testing companies: erictopol.substack.com/p/the-business…. I'd add real tragedy is that this crap obscures and besmirches truly exceptional progress in geroscience

Extraordinarily poignant. Also suggest reading his previous piece on same topic: thefp.com/p/the-winner-o…. This is another powerful and beautiful recent piece on similar topic: nejm.org/doi/abs/10.105…. Given prevalence of AD in aging population, likely an incr common experience
