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.

You Will Own Nothing and Be Happy

In her original post, Auken predicted a time, viz. 2030, wherein she would not ‘own anything’, not a car, a house, nor even any clothes. This was because, she explained, all things previously regarded as a ‘product’ would be supplied and available in the future as a ‘service’. As a result, everything that one might need could be rented, thereby eliminating the need, although not necessarily the right, to ‘own anything’. This was “a good life”, Auken concluded.

Artificial Intelligence (AI) in the Classroom?

Retraction Note to: Humanities and Social Sciences Communications https://doi.org/10.1057/s41599-025-04787-y, published online 06 May 2025. The Editor has decided to retract this paper owing to concerns regarding discrepancies in the meta-analysis. These issues ultimately undermine the confidence the Editor can place in the validity of the analysis and resulting conclusions. The authors have not responded to correspondence regarding this retraction. Retraction Note: The effect of ChatGPT on students’ learning performance, learning perception, and higher-order thinking: insights from a meta-analysishttps://www.nature.com/articles/s41599-026-07310-z

The jury’s still out on AI’s effectiveness as a learning tool, but research so far paints a grim picture. Using AI chatbots can impair critical thinking, result in lower brain activity during cognitive tasks, and has been linked to memory loss. A Major Paper Claiming AI Is Good for Students Just Got Retracted, Which Is Very Bad News for Advocates of AI in the Classroomhttps://futurism.com/artificial-intelligence/study-ai-good-for-students-retracted

AI’s effectiveness as a learning tool is probably better for people who already know how to think having “learned” stuff the old fashioned way. AI’s effectiveness as a learning tool for some of the younger generations has shown promise in one area known as cheating.

Last year, a survey of some 500 Princeton seniors found that over 27 percent admitted to cheating with an AI model like ChatGPT, while about half said they knew about a violation of the honor code. If those are the numbers at a vaunted Ivy league, just imagine what conditions are like for the rest of the country. Princeton in Shambles Over AI Cheatinghttps://futurism.com/future-society/princeton-shambles-ai-cheating

BTW, the estimated cost of attendance for 2026-27 is $94,624 at Princeton U. https://admission.princeton.edu/cost-aid/fees-payment-options

Maybe the Princeton kids had to cheat because they offloaded too much of their own thinking and by default, didn’t learn how to think.

The risks of using generative artificial intelligence to educate children and teens currently overshadow the benefits, according to a new study by the Brookings Institution’s Center for Universal Education… The report describes a kind of doom loop of AI dependence, where students increasingly off-load their own thinking onto the technology, leading to the kind of cognitive decline or atrophy more commonly associated with aging brains… Rebecca Winthrop, one of the report’s authors and a senior fellow at Brookings, warns, “When kids use generative AI that tells them what the answer is they are not thinking for themselves. They’re not learning to parse truth from fiction. They’re not learning to understand what makes a good argument. They’re not learning about different perspectives in the world because they’re actually not engaging in the material. The risks of AI in schools outweigh the benefitshttps://www.npr.org/2026/01/14/nx-s1-5674741/ai-schools-education?

Your final food for thought.

I climb telephone poles. It’s awesome.

In a small Ohio city between Dayton and Columbus, the American Dream is alive and well for 24-year-old Kyson Cook. The father of one owns a three-bedroom home, has no debt beyond his mortgage and ends most workdays around 4:30 p.m., leaving plenty of time to shoot pool, go fishing or spend time with family. He has a small plot of land with space for his daughter to play, along with enough money to buy her whatever toys she wants and regularly contribute to a mutual fund with her name on it, without needing to cut back on new clothes, vacations or eating out. The AI economy is rewriting the American Dream — and blue-collar workers are poised to winhttps://www.cnbc.com/2026/05/19/ai-hiring-slowdown-skilled-trade-workers.html

Let’s create existential distress and deep anxiety in your employees!

Taking the brunt of this are young workers. According to a recent survey by yet another consulting firm, most of the AI-driven headcount reduction that CEOs are bracing for is expected to focus on early-career positions. The reasoning for that, as it goes, is that AI is best at automating simpler tasks that an early-career worker would be expected to perform at a company as they get on-the-job training needed to mature into higher-level positions. But many executives, dazzled by the promise of an AI chatbot that can finish tasks in mere seconds and work 24/7 without needing so much as a bathroom break, have said to hell with early-career workers and training the future of the workforce. 99% of CEOs Expect AI-Driven Layoffs in the Next Two Yearshttps://gizmodo.com/99-of-ceos-expect-ai-driven-layoffs-in-the-next-two-years-2000762994

We document that one factor contributing to youth unemployment is the four-fold rise in remote work since the pandemic. Employers may not want to hire fresh graduates onto distributed teams because it is more difficult to teach them the requisite skills from afar.

The Fear Shared By Most (Not Just Another Random Thought on Retirement)

If there’s one thing Americans fear more than death, it might be outliving their savings. That’s one finding from an annual survey by the Allianz Center for the Future of Retirement. It found that 67% of Americans worry more about running out of money than death. Americans fear this retirement setback more than death – https://www.usatoday.com/story/money/2026/05/04/retirement-fears-outliving-savings/89897704007/

Yes dear reader, yet another post in the never ending series of random thoughts on retirement. For the curious, here’s a link to some previous posts https://lifeunderwriter.net/tag/retirement/. I am an Old Guy who is old enough to be retired but isn’t retired and still working. After many mornings spent in deep contemplation and many posts where I think out loud I’ve finally accepted my fate and come to a deeper understanding of why I do what I do.

I’ve spent a lifetime working in risk management. Finally, the light bulb came on.

I am actively managing my longevity risk. It’s what I do. I manage risks.

The majority of our friends are retired. I’m always asked when I’m going to retire. My answer was always “Don’t know”. I subsequently modified my response to “Two to four years”. This has been my answer for the past two years. But now when someone asks when I will retire, my answer will be:

I am managing my longevity risk. I am managing future inflation risk.

Imagine you retire at 65, feeling confident. You’ve budgeted $80,000 a year to live comfortably — travel, dining out, covering healthcare, the works.

Fast-forward 25 years.

At age 85, you’re still spending about $80,000 a year … but that no longer buys what it used to.

  • That nice dinner out that cost $100 now costs about $210
  • A $5,000 annual vacation is now closer to $10,500
  • Groceries that ran $10,000 a year are now over $21,000

In other words, your $80,000 lifestyle now costs roughly $168,000 to maintain.

But if your income hasn’t kept pace — if it’s still around $80,000 — your lifestyle has effectively been cut in half. Inflation Is the New Fixed Expense in Retirement https://www.kiplinger.com/retirement/retirement-planning/inflation-the-new-fixed-expense-in-retirement

Economist Teresa Ghilarducci is of the opinion working longer is not a plan but an illusion.

My colleagues Anthony Webb, Michael Papadopoulos and I called it an illusion. In paper The Illusory Benefits of Working Longer on Financial Preparedness for Retirement, we found that older workers with insufficient savings are routinely advised to delay retirement — but that this advice collides with the reality of what the labor market actually offers aging workers. 62-Year Old Works His Whole Life. He Has No Savings. He’s Not Unusual.https://www.forbes.com/sites/teresaghilarducci/2026/05/21/62-year-old-works-his-whole-life-he-has-no-savings-hes-not-unusual/

Ghilarducci is spot on with her assessment. My plan on working longer wasn’t really a plan so much as it was a set of assumptions. Everything had to go as “planned” or forget about working longer. The two major variables were continued good health and finding an employer that values older workers.

I got lucky. My illusion is working (pun intended).

How To Reduce Your DM2 Risk 31%

The results, published in Annals of Internal Medicine, were based on 4,746 adults between ages 55 and 75. All had overweight or obesity and metabolic syndrome, but none had diabetes or cardiovascular disease at the start of the study. Researchers followed participants for six years to see whether a more intensive Mediterranean based lifestyle plan could offer stronger protection against type 2 diabetes than the traditional Mediterranean diet alone.

One group followed a calorie reduced Mediterranean diet (about 600 kcal fewer per day), added moderate physical activity (brisk walking, strength and balance training), and received professional guidance. The comparison group followed a traditional Mediterranean diet without calorie restriction or exercise advice.

The difference between the two approaches was striking. Participants in the intervention group were 31% less likely to develop type 2 diabetes than those in the comparison group. Universidad de Navarra. “Scientists found a smarter Mediterranean diet that slashes diabetes risk by 31%.” ScienceDaily. https://www.sciencedaily.com/releases/2026/05/260519003103.htm (accessed May 23, 2026).

I just had my annual wellness check and got my lab results. All good except my fasting glucose.

Yikes. Memo to Self, get an A1C. Well, the very next day…

Doc says:

CMP (Comprehensive Metabolic Panel): Your creatinine (a measure related to kidney function) is low, and your blood sugar (glucose) is high; all other values are normal. This test checks how your kidneys and liver are working, your body salts, proteins, and blood sugar. Low creatinine can happen in people with less muscle and may be expected. The slightly high fasting blood sugar could indicate early changes in how your body handles sugar. Options include repeating the blood sugar test next visit.

I know my diet could be better. I know I should eat less, snack less and maybe, just maybe stop drinking beer. But also knowing my IFG is worsening I wondered if there was a diet (besides MedDiet) for IFG?

In recent years, low-calorie diets ranging from 800–1500 kcal/day have gained significant attention in managing type 2 diabetes8,1619. Studies have shown that low-calorie diets can lead to remission and substantial improvements in cardiometabolic risk factors for a significant proportion of individuals with type 2 diabetes8,1619. These diets are generally well-tolerated and safe, with only mild side effects reported. Table 1 summarizes the key low-calorie diet studies conducted in people with type 2 diabetes8,1619. Studies implementing low-calorie diets over a 2–5 month period, primarily high in protein and low in fat, have resulted in a mean weight loss of 7–15 kg (8–15% of initial body weight). This level of weight loss was accompanied by a notable reduction in hepatic fat and improved hepatic insulin sensitivity and first-phase insulin secretion. As a result, fasting plasma glucose levels decreased significantly by 27.8 to 43.2 mg/dL. This suggests that low-calorie diets may also be effective for individuals with i-IFG, as they target the pathophysiological defects characterizing this prediabetes phenotype8,1619. Figure 1 visually depicts the potential reversal of the twin cycle hypothesis through low-calorie diets in individuals with i-IFG. The twin cycle hypothesis20 postulates that chronic excess calorie intake results in increased accumulation of fat in the liver, leading to resistance against insulin’s suppression of hepatic glucose production. Additionally, excess liver fat increases lipid transportation to the pancreas, impairing β-cell function and further promoting hepatic glucose production. These self-reinforcing cycles between the liver and pancreas ultimately result  in the onset of hyperglycemia.

The Plan

  • Eat less
  • Move more
  • Drink less beer

I like to keep things simple.

“I think the junior level is definitely finding it harder now to enter the workforce,” said John Romeo, who leads the consulting firm’s research arm, the Oliver Wyman Forum. “It’s those mid- and senior-level employees that CEOs are now looking at to drive productivity.” That’s because of the types of tasks that AI agents are able to perform, from writing code at the level of a junior developer to evaluating sales leads. What the agents can’t do in many fields is make judgment calls using the insight that comes from on-the-job experience, according to labor experts.

Optimize This!

But the productivity gurus were child’s play compared to the rise of the biohacking movement that followed. Guys like Andrew Huberman and Bryan Johnson rose to fame in recent years with their strict diets, excessive supplementation, and elaborate morning routines. Science-backed exercise and nutrition advice became the name of the game. And there was no shortage of influencers to supply it. Optimizing Ourselves to Deathhttps://ofdollarsanddata.com/optimizing-ourselves-to-death/

You can’t optimize everything. Mistakes will be made and are part of life. Sub-optimal for whatever you are chasing will be the end result because perfection is impossible.

Neurodegenerative Copathology

About 20 years ago, neuropathologists began to report an inconvenient finding in the autopsied brains of people with dementia: Most have evidence of more than one disease. Studies since have shown the brains of up to half of people diagnosed with Alzheimer’s disease also have a key feature of Parkinson’s disease—deposits of the protein alpha synuclein. At the same time, up to half of Parkinson’s patients who develop dementia have elevated levels of beta amyloid and tau proteins, hallmarks of Alzheimer’s.
