Spaces like NASEM and #IAPHS. I have written external promotion and tenure letters for epidemiology , geoscience, health policy, and neuroscience more often in the past 3 years than my home discipline of sociology. My takeaway is that our identities are increasingly fluid as we advance in our

My lab group met today. Grad students and postdocs engaged in cutting edge research on health and aging topics. Every meeting it seems that they have a new article accepted or fascinating results. They’re provocative and fun! The next generation in this area of science. I love it!

I continue to be stunned at how poor health literacy is in the US. You’d think folks would have learned something during the worst of the pandemic. It almost seems the opposite. Perhaps the COVID “worm” ate people’s brains.

Today in my mortality grad seminar, we focused on what transpired in the US & comparisons with high income countries.The students were shocked by how devastating COVID was to US life expectancy compare to Europe. Then we discussed the Great Barringron Declaration. They were stunned.

A brilliant summary. Thanks.

You deserve kudos for being able to watch this train wreck. I'm low on prozac so avoiding the news media coverage of the vaccines. Got my jab yesterday, and my poor pharmacist was crazy busy giving other folks the jab yesterday too. Clearly, at least some Americans are worried as hell.

If you think the far rights’ proposals to raise US birth rates will work, think again. www.newsweek.com/low-birth-ra...

Individuals and families need to be supported by a strong social safety net that includes paid leave and a robust child care infrastructure. There are no quick fixes.

I so agree with you. It’s almost palpable.

Finally, a UA pilot on my last flight commented about the significance of today. He lost 2 friends who were pilots of the UA flights that crashed that day. I’m really glad he said something.

I was thinking about 9/11 today as I was traipsing around airports. I was surprised by the lack of government attention and the media. 9/11 was a turning point in our history and had wide consequences, e.g., the War on Terror, the establishment of Homeland Security and wars in the Middle East. 1/2

#IAPHS I’m at a population health science conference in Pittsburgh. Researchers from many disciplines have gathered to talk about ways of improving health, bringing in “cells to society” perspectives. So wonderful at a time when HHS has declared war on the health sciences. Science will triumph.

I’m traveling for biz. Staying at the Westin in Pittsburgh. I’m in the bar and just watched the bartender help out a street person fill their thermos with ice water. I love this place even more. Kindness. It still exists.

It’s shocking isn’t it? I suspect that people actually care more about their pets than they do about kids. A sad state of affairs. Especially for people who are pushing higher fertility.

I continue to have a hard time why Evangelicals and Republicans consciously choose to harm people’s health. That makes my head spin too

Mark Hayward @mdhayward.bsky.social · Sep 5

My head spins when I see vaccine resistance—especially for children. Children’s lives in today’s world are at serious risk because of vaccine resistance. How do I know?Because of a real life counterfactual. Yeah, science

Some days I wonder whether Kennedy will start staffing CDC with witch doctors. Clearly, the germ theory of disease has been demoted within CDC.

Breaking: RFK Jr. seeks to rush 7 new members to CDC vaccine panel.

We have breaking news that I believe we are first to report here in Inside Medicine.

I hear you!

When the USSR was collapsing, they stopped publishing life tables because life expectancy was rapidly declining between 1974 and 1986. That’s one of the indicators the CIA used to gauge the level of internal rot in the USSR. Makes me wonder whether the US will continue publishing its life tables.

I’d really prefer not to go to Mexico or Canada for my Covid booster. Just saying.

It makes me wonder whether plastic sandwiches attached to DC residents’ backpacks, briefcases, cars, and bicycles might have a similar effect on the occupation of DC by the military and ICE, our own American Gestapo. Protest with a sense of humor.

Years ago UT students protested the Texas Lege allowing guns on campus. The students started a passive protest, “Cocks for Glocks.” They attached dildoes to their backpacks, bicycles, whatever. The campus was flooded with sex toys to affirm how stupid our Lege was. 1/

Summer in Austin is now 24 days longer than it was 30 years ago. A longer summer is the case just about everywhere in the US. Maybe that’s why the feds are closing down climate research and disappearing the data.

Perfect description.

Here’s an example — among so many — of how the GOP kills great institutions — but is incapable of building them.

UT System nixes faculty senates, approves restrictions on campus protests

The changes are in response to new state laws seeking to limit faculty’s influence and put guardrails on campus demonstrations.

Nothing says grandparent love like waygu hot dogs, fancy ice cream sandwiches and pool time. Unless we had a pony. 🤣

My neighborhood has a group chat in WhatsApp. Today they are chatting away about housekeeping services, contact information for their housekeepers, cost, etc, blissfully unaware that they could be placing people at risk of "La Migra." Stupid, rich White people.

If the National Guard and FBI just circle the White House, maybe that will encourage the criminals there to give themselves up.
