These large national cohorts provided data that supported healthcare policymaking across the public and private sectors. They were some of the most important works that only CDC was able to perform - and execute well - as a nationally representative survey.

CDC team running top survey on health and nutrition is laid off
NHANES has collected data on eating patterns, diabetes, and other common diseases for decades. The CDC team that runs it has been fired.

Aging well has increasingly focused on lab values & fitness scores. Often overlooked: engaging w other people. "Why Brains Need Friends" distills the science showing connection fuels resilience, enhances length, quality of life. My @wsj.com rev: www.wsj.com/arts-culture... @nachristakis.bsky.social
‘Why Brains Need Friends’ Review: Better Together
Research shows that social connection improves health and well-being. The challenge of isolation intensifies with age.

Yes and - I really think everyone has lost patience with reading almost anything, esp when it's so easy to find pithy distillates in a range of forms. Even most actual essays seem to exist mostly to serve as the basis for podcasts and soc med posts.

TFW it sinks in that no one actually reads anything. Not when you cognitively recognize this, but when you viscerally understand it and know it to be true.

My latest TR column, discussing progress+ambition in consumer health-esp convergence around "personal health OS." Excited about much of this work, but disappointed by continued reductionist view of health as metric optimization timmermanreport.com/2025/10/consum… @alicecallahan.bsky.social

Each of these companies should be free to fire employees for performance. That can be subjective! No one is entitled to million-dollar paychecks for big news & entertainment jobs.

But when decisions are made to hire and fire to appease a vengeful ruler that’s different. That’s autocracy at work.

In addition to whatever this says about wellness, it also speaks to where the audience is perceived to be - it looks like if you want to reach most people impactfully, you need high impact video clips; suspect @zekeemanuel.bsky.social will likely add Youtube, also some kind of podcast...

Japan has a wrestling camp for kids where at the end they have a show match in front of their parents to show off what they learned.

Thought you'd enjoy this.
