In this prospective cohort study, resistance training among US adult health care professionals was associated with substantially lower T2D risk, particularly when performed consistently over midlife and combined with adequate aerobic activity and limited sedentary television viewing. These findings support the inclusion of resistance training as a key component of lifestyle recommendations for diabetes prevention.

Not Everyone Gets Lucky
My interviews with Howard Marks, Chairman of Oaktree Capital, and famed for his “Chairman’s Memos,” were instructive.1 The first time he mentioned his good fortune, I pushed back, asking, “What about intelligence, hard work, and perseverance?”
His answer:
“Everybody in my MBA class at the University of Chicago was very smart and very hard working. But hard work and intelligence are mere table stakes. Not everybody has fortune smile on them; not everybody gets lucky.”

Study Failure to Learn Success
Michael Girdley on private equity:
The lesson is pretty straightforward. You’re going to go buy a business, and you’re going to look and say, “Where can I cut costs? How can I start to optimize and streamline this?” You can cut fat, but you definitely don’t want to cut muscle, and you don’t want to cut bone. That’s exactly what these guys did. Why did they do that? They’re private equity guys. They get paid on management fees and the deals when they turn around and put them out in the public. They don’t care about the long term. They care about the next three to five years, and that’s exactly what they optimized for.

Alarmingly Shallow Ideas
As one New York financier told Financial Times journalist Gillian Tett, new hires who were seen as “AI natives” are turning out to have alarmingly shallow ideas. So much so, the anonymous finance worker admitted, that his firm now actively avoids seeking out AI-literate STEM graduates, and opts to comb through humanities students instead…
The state of higher education is so bad that many of today’s higher ed students are not only offloading their coursework to AI chatbots like ChatGPT — a shortcut, educators say, that’s even impacting their ability to participate in face-to-face discussions.

Yikes.
Deeply disturbing. So what can a concerned parent do?
Ask ChatGPT what to do!
My college graduate son has no critical thinking skills after relying upon ChatGPT. What should I do?
Treat this as a skills-and-habits problem, not a character flaw or a “ChatGPT ruined him” problem. A lot of recent graduates learned to use AI as a shortcut before they learned how to think through ambiguity on their own. The good news is that critical thinking is trainable.
A few things matter here:
- Don’t turn this into a fight about technology
- Separate competence from confidence
- Create situations where he has to reason, decide, and defend conclusions
What often happens is:
- Students get very good at producing polished answers
- But weak at:
- evaluating evidence
- making tradeoffs
- spotting bad assumptions
- persisting through confusion
- forming independent judgment
Those are different skills.
Here’s what tends to work better than lectures about “kids relying on AI.”
Change how he uses AI
The goal is not “stop using ChatGPT.” It’s “use it as a sparring partner instead of a vending machine.”
Encourage rules like:
- No copying answers directly
- He must form an opinion first
- He must explain why an answer is correct
- He must ask AI to critique his reasoning instead of replacing it
Good prompts:
- “Challenge my assumptions.”
- “What are the strongest counterarguments?”
- “What evidence would disprove this?”
- “What am I overlooking?”
- “Give me three competing interpretations.”
Bad pattern:
- “Write this for me.”
Put him in environments that punish shallow thinking
Critical thinking develops fastest when reality pushes back.
Good environments:
- Jobs with responsibility and consequences
- Sales
- Operations
- Managing projects
- Technical troubleshooting
- Apprenticeships
- Debate-heavy workplaces
- Entrepreneurship
- Volunteer leadership
Real-world feedback is hard to fake.
Ask questions instead of giving conclusions
If you immediately correct him, he stays mentally passive.
Instead ask:
- “How did you arrive at that?”
- “What evidence supports it?”
- “What would change your mind?”
- “What’s the downside of your approach?”
- “What assumption are you making?”
That forces metacognition.
Make him defend positions he disagrees with
One of the fastest ways to build reasoning is:
- argue both sides
- compare tradeoffs
- steelman opposing views
You can do this casually over dinner or current events.
Encourage slow thinking
A lot of AI-heavy habits create intellectual impatience.
Critical thinking often requires:
- sitting with uncertainty
- reading longer material
- comparing sources
- wrestling with incomplete information
Books, long-form journalism, analytical podcasts, and difficult projects help rebuild that stamina.
Watch for learned helplessness
Sometimes the issue is not inability but reflexive dependence:
- “I don’t know immediately”
→ “I need AI to think for me”
A useful rule:
- Spend 15–30 minutes thinking independently before asking AI.
Also be realistic about the transition to adulthood
Many graduates — long before AI existed — left college without strong judgment skills. Those usually develop through:
- responsibility
- mistakes
- work
- relationships
- financial pressure
- repeated decision-making
You do not need to panic because he’s behind in one area at graduation.
The biggest mistake parents make here is trying to “convince” an adult child that he lacks critical thinking. That usually triggers defensiveness and dependency at the same time.
A better posture is:
- respect him as an adult
- expect reasoning and accountability
- ask probing questions
- stop rescuing poor decisions too quickly
- encourage environments that require independent judgment
If you want, I can also help you with:
- signs that this is normal vs genuinely concerning
- exercises that rebuild critical thinking quickly
- how to talk to him without sounding accusatory
- ways young professionals can use AI without weakening reasoning skills
GLP-1s (it’s kind of a mess)
“But the real question is what is the quality of the weight regain and what is the shift in people’s metabolism, and it seems to be very bad,” she said. “Ongoing studies that haven’t been published yet suggest that hypertension comes back. All the inflammatory markers come back, and lipids go up. And if you have diabetes, it gets worse. Overall, it’s kind of a mess…As these studies and others showed, most people regain the weight. Whether or not they regain all the weight depends in part on diabetes and insulin and many other factors, but people will likely regain most of their weight.”
“But the message isn’t that you regain the weight. The message is that you may be less healthy when you regain the weight. That’s why we need to couple the drugs with lifestyle interventions. And it’s why people who just want to lose 5 or 10 pounds really need to consider that lifestyle change, hard as it is, is the better way to do it.”

The Nutritional Challenges of Advanced Age
The study focused exclusively on adults 80 and older, a group with very different dietary requirements than younger adults. As people age, the body goes through significant physiological changes. Energy expenditure decreases, and losses in muscle mass, bone density, and appetite are common. Together, these changes increase the risk of malnutrition and frailty.
Most evidence for the health benefits of diets that exclude meat comes from studies of younger adults rather than frail older populations. Some research suggests older non-meat eaters face a higher risk of fractures due to lower calcium and protein intake.
In later life, nutritional priorities shift. Rather than focusing on preventing long-term diseases, the goal becomes maintaining muscle mass, preventing weight loss and ensuring every mouthful delivers plenty of nutrients.

The Edge
My takeaways:
The first takeaway is about the mindset. Winning requires staying in the present. When you lose nearly half the points you play, the past offers no help. Dwelling on past mistakes only distracts from the real goal, which is to win the match. We cannot change what has happened, and we cannot control what comes next. Stay present, follow the process, and let the result take care of itself…The idea of edge applies directly to our lives. Life is made up of thousands of decisions taken over decades. A small edge in how we make those decisions quietly stacks the odds in our favor.
Take health. Lifting weights a few times a week, walking a few miles a day, eating reasonably well, and sleeping enough each give us a small edge. We are not competing with anyone else here. We are competing against chronic diseases. These habits do not guarantee outcomes, but they help us avoid most of the problems that are within our control, and leave the rest to chance. None of these decisions matter much on their own. Taken together over years they matter a lot.

Keep Moving
Physical activity consistently emerges as the most important factor influencing both absolute physical capacity and the rate of age-related decline. Our longitudinal data are consistent with previous studies showing that regular physical activity can attenuate the decline in physical performance [17, 32–37]. Individuals who were physically active in their leisure time at age 16 maintained higher aerobic capacity, muscular endurance and muscle power throughout the observation period. This emphasizes the importance of early intervention to establish positive exercise habits in adolescence and early adulthood, as these patterns appear to have long-term benefits for physical function. Encouragingly, our results show that transitioning from physical inactivity to activity at any age significantly improves performance in all fitness modalities studied. These findings contradict the assumption that early inactivity irreversibly impairs physical performance. Rather, taking up regular physical activity leads to measurable improvements in performance even in later decades of life. This finding is of particular importance for clinical practice, as physical activity is still the only evidence-based intervention to reduce the risk of sarcopenia [2, 38]. Recent large population studies also show that an active lifestyle is beneficial at any age [13, 39, 40].
