“Normal” Human Temperature May Be Lower When Baseline Inflammation Is Lower

When I was a child my mother would hand me an oral thermometer to take my temperature and often the temperature would come out below 98.6 degrees. She would be annoyed and hand it back to me, saying that I should put it in right this time. I would painfully jab the thermometer back under my tongue, discouraged that I would never figure out what I was doing wrong. So several decades later, I smiled when I read the commentary quoted below. (Hey mom, maybe I was doing it OK all along.)

(p. A2) Nearly 150 years ago, a German physician analyzed a million temperatures from 25,000 patients and concluded that normal human-body temperature is 98.6 degrees Fahrenheit.

That standard has been published in numerous medical texts and helped generations of parents judge the gravity of a child’s illness.

But at least two dozen modern studies have concluded the number is too high.

The findings have prompted speculation that the pioneering analysis published in 1869 by Carl Reinhold August Wunderlich was flawed.

Or was it?

In a new study, researchers from Stanford University argue that Wunderlich’s number was correct at the time but is no longer accurate because the human body has changed.

Today, they say, the average normal human-body temperature is closer to 97.5 degrees Fahrenheit.

. . .

“Wunderlich did a brilliant job,” Dr. Parsonnet said, “but people who walked into his office had tuberculosis, they had dysentery, they had bone infections that had festered their entire lives, they were exposed to infectious diseases we’ve never seen.”

For his study, he did try to measure the temperatures of healthy people, she said, but even so, life expectancy at the time was 38 years, and chronic infections such as gum disease and syphilis afflicted large portions of the population. Dr. Parsonnet suspects inflammation caused by those and other persistent maladies explains the temperature documented by Wunderlich and that a population-level change in inflammation is the most plausible explanation for a decrease in temperature.

Mathematical Disciplines Need the “Re-injection” of “Empirical Ideas”

(p. C4) Mathematicians have faced a similar choice between pure and applied work for millennia. In his 1940 book “A Mathematician’s Apology,” G.H. Hardy made a hard-core case for purity: “But is not the position of an ordinary applied mathematician in some ways a little pathetic?…‘Imaginary’ universes are so much more beautiful than this stupidly constructed ‘real’ one.”

On the other hand, John von Neumann rebuked purity in his 1947 essay “The Mathematician”: “As a mathematical discipline travels far from its empirical source…it is beset with very grave dangers. It becomes more and more purely aestheticizing,…whenever this stage is reached, the only remedy seems to me to be the rejuvenating return to the source: the re-injection of more or less directly empirical ideas.”

I think von Neumann has the better of this argument. In his own career, he used his mathematical talents to pioneer fields like game theory and computer science, leaving a titanic legacy, practical as well as intellectual.

Ranchers Will Protect and Invest in Brazilian Forest Land That They Own

(p. A1) POMBAL, Brazil—For the past 15 years, Carlos Pacheco has raised cattle in what was once virgin forest. When pastures went bad, he would simply cut deeper into the Amazon, one of millions of farmers who have helped strip away about a fifth of the world’s greatest rainforest.

Because he expanded into land he doesn’t own, he can’t use it as collateral for a loan to buy equipment and fertilizer, nor can he tap the expertise of a government agronomist. The upshot is that he uses more land to raise each cow than do legal farmers in the breadbasket of southern Brazil.

It may sound counterintuitive, but Brazilian authorities think giving Mr. Pacheco a deed to the land he farms might curtail deforestation. The idea is it could help him become a more efficient farmer, able to produce more on less land, and also make him hesitate to just walk away from depleted pastures and carve new ones. In short, it might discourage him and squatters like him from cutting ever deeper into the jungle.

“If this doesn’t happen, we will continue to deforest,” said the 49-year-old rancher, the leader of a tightknit group of several hundred settlers on the forest frontier.

The administration of Brazilian President Jair Bolsonaro wants to see if he is right. In February [2020], it plans to start handing out deeds to some 300,000 Amazon squatters, with a plan that might help but has raised a howl of disapproval for re-(p. A12)warding bad behavior.

. . .

Over the decades, 73-year-old cattleman João Bueno cut into the forest in Pará state to build a network of ranches totaling 45,000 acres, with 28,000 head of cattle.

He has a special document that allows him to produce and sell cattle to a slaughterhouse, but it isn’t a title, so it doesn’t allow him to use the land as loan collateral. Mr. Bueno said tapping credit would permit him to modernize his operation with fertilizer and techniques common elsewhere, raising three times as many head of cattle on the same acreage.

“Land without documentation is nobody’s land, so people take advantage of it to clear forest for pastures,” Mr. Bueno said.

How “Single-Payer” Socialized Medicine Works for American Indians

(p. A1) EAGLE BUTTE, S.D.—Kate Miner walked into the Indian Health Service hospital, seeking help for a cough that wouldn’t quit.

An X-ray taken of Ms. Miner’s lungs that day, Oct. 19, 2016, found signs of cancer.

What exactly the IHS doctor said to Ms. Miner about her exam remains in dispute. Notations in her medical file indicate the doctor told her to come back for a lung scan the next day. Her family says they never were given such instructions and weren’t told of the two masses the X-ray revealed.

What is clear is that no further tests were done. And no IHS provider followed up when Ms. Miner returned twice more to the hospital, the only one on the Cheyenne River Reservation, over the next six months, medical records show.

Finally, on May 7, 2017, as the 67-year-old Ms. Miner lay crumpled on a hospital cot, the right side of her body shaking, a physician assistant ordered a CT scan, after her family insisted, according to the records and family members.

“You have two very large masses in your right lung. It’s probably a malignancy,” Ms. Miner’s daughter Kali Tree Top recalled the physician assistant saying.

Ms. Miner reached for her daughter’s hand and started to cry.

Ms. Miner’s encounters with the IHS, and her family’s repeated efforts to get her help there, illustrate how the federal agency can fail the patients who need it most.

Opposed by China and WHO, Trump Administration Declared Covid-19 Public Health Emergency on January 31, 2020

(p. A1) The U.S. imposed entry restrictions on foreign nationals and quarantines on Americans returning from the Chinese province at the center of the coronavirus outbreak, as markets tumbled over fears about the impact on global growth.

Health and Human Services Secretary Alex Azar declared a public health emergency Friday [Jan. 31, 2020]. He said foreign citizens who have traveled anywhere in China within the past 14 days would be denied U.S. entry, while Americans who visited Hubei province would be quarantined for up to two weeks.

. . .

(p. A8) “Many countries have offered China support in various means. In sharp contrast, certain U.S. officials’ words and actions are neither factual nor appropriate,” Chinese Foreign Ministry spokeswoman Hua Chunying said. “Just as the WHO recommended against travel restrictions, the U.S. rushed to go in the opposite way.”

Apple Will Make Its Own Mac Processor Chips

In similar stories told in books by Grove and by Christensen and Raynor, technology firms work better when large, if components require careful design to work well together. When components become standardized and interchangeable, technology firms work better when smaller, buying components from specialized component suppliers. Deciding what is best at any moment requires uncertain judgement, and can change over time. In the passages quoted below, it appears that Apple thinks better performance can be achieved by integrating a key component back within the firm.

(p. B4) Apple Inc. built its gadget empire by outsourcing production to a vast ecosystem of chip makers and other component specialists. Under Chief Executive Tim Cook, it is taking a lot of that business back.

The company, which released its first iPhone processor in 2010, said Monday [June 22, 2020] it plans to ship Macs later this year with custom chips, a move that ends a 15-year technology partnership with Intel Corp. Apple said the custom-designed chips are more efficient and offer higher-performance graphics.

. . .

The strategy springs from Apple’s philosophy—fostered by its late co-founder Steve Jobs—that owning core technologies provides a competitive edge. Customized chips and sensors can help its iPhone, iPads and Macs leapfrog rivals in battery performance and features. It also can protect Apple from Chinese rivals that buy universally available parts.

. . .

The initiative—called insourcing by some suppliers and analysts—can give Apple a two-year jump on competitors in device performance because Apple can plan how multiple chips work together to limit power consumption and free up space inside iPhones and iPads for other components, analysts said.

It also reduces potential leaks of its product plans.

“Run With the Herd or Be Crushed by It”

The author of the passages quoted below writes poetry and novels in Havana.

(p. 7) Throughout my life, I’ve seen how powerless parents are in matters regarding their own children. Parents have no say over how their children should be raised, whether they will be conscripted or sent away to school in rural areas, and what dangers could befall them being so far from home and such a young age. They have no say over their children’s manners, religious teachings and political ideologies. There are only two choices: Run with the herd or be crushed by it.

As a teenager in the 1980s, I was taught in a “scientific communism” class that family was the heart of society. But from what I could see, that was no longer the case; organizations with mass followings like the Young Communist League had taken its place.

. . .

I was born and raised in a system that exerts control under the guise of paternalism — a system that caresses you as it beats you, that teaches you but also inhibits you, enlightens you and censures you. We are hostages to a government that behaves like an abusive, old-fashioned and sexist father, from whom we must seek consent and forgiveness.

Resilient Eaten Beetle Persists to the End

(p. D2) It’s a familiar story: Predator hunts prey. Predator catches prey. Predator gulps down prey.

Usually, that’s it. But the water scavenger beetle Regimbartia attenuata says, “Not today.” After getting swallowed by a frog, this plucky little insect can scuttle down the amphibian’s gut and force it to poop — emerging slightly soiled, but very much alive.

Wasteful Administrative Health Care Costs

The study quoted from below suggests that the main cure for wasteful administrative costs is a “single payer” system, which is a politically correct euphemism for socialized medicine. I suggest that a better cure would be to eliminate the government middle-man, and make the patient be the payer. The patient as payer would seek and buy low-cost cures or therapies, which would shift efforts at healthcare innovation toward lower cost innovations. As has been suggested for education, vouchers could provide poor patients with the means to pay for basic care.

(p. B4) Even a divided America can agree on this goal: a health system that is cheaper but doesn’t sacrifice quality. In other words, just get rid of the waste.
A new study, published Monday [October 7, 2020] in JAMA, finds that roughly 20 percent to 25 percent of American health care spending is wasteful. It’s a startling number but not a new finding. What is surprising is how little we know about how to prevent it.

. . .

Teresa Rogstad of Humana and Natasha Parekh, a physician with the University of Pittsburgh, were co-authors of the study, which combed through 54 studies and reports published since 2012 that estimated the waste or savings from changes in practice and policy.

. . .

The estimated waste is at least $760 billion per year. That’s comparable to government spending on Medicare and exceeds national military spending, as well as total primary and secondary education spending.

. . .

The largest source of waste, according to the study, is administrative costs, totaling $266 billion a year. This includes time and resources devoted to billing and reporting to insurers and public programs. Despite this high cost, the authors found no studies that evaluate approaches to reducing it.

Jim Collins Book “Had a Huge Influence” on Reed Hastings’s Creation of Netflix

(p. 6) The Netflix founder and co-chief executive, whose new book is ‘No Rules Rules,’ reads with his mind more than his heart: ‘I generally turn more to television and film for emotional nourishment.’

. . .

What’s your favorite book no one else has heard of?

Probably “Beyond Entrepreneurship,” by Jim Collins and William C. Lazier. It’s not nearly as well known as Collins’s “Good to Great” or “Built to Last” in the pantheon of influential business books. But it came out in the early 1990s, right around the time I was starting my first company, Pure Software. It had a huge influence on how I thought about that business and, later, what I aspired to create at Netflix. Collins and other business authors whose books I benefited from are a big reason I decided to write a book of my own, to try to pay it forward to other entrepreneurs in the same way those other authors have. Years from now, it would be great if someone who found “No Rules Rules” useful today writes their own book improving on it..

. . .

What do you plan to read next?

“Shoe Dog,” the memoir by Phil Knight, who created Nike — and yes, we’re also adapting it for Netflix.

Bikini Atoll Is “Best Example of the Earth’s Resilience”

(p. A13) . . . “The Age of Nature” is not just a beautifully made series, it’s also a surprisingly joyful one. It’s about rehabilitation—how humans are correcting environmental outrages from Panama to Mozambique to Central China to Yellowstone Park—and how forgiving Mother Nature can be if we just pay her some affectionate attention.  . . .

The best example of the Earth’s resilience might be the first location visited, Bikini Atoll—or, rather, the crater left by the 23 nuclear detonations the U.S. set off there from 1946-58. More than 60 years later, humans still can’t live in the immediate area, but under the South Pacific’s surface, anemones, polyps, sharks and wrasses flourish in and around the coral reefs that have somehow clung or sprung back to life.  . . .

Elsewhere around the globe, similar acts of restoration and reparation are taking place, or already have: In the ’90s, China’s Loess Plateau, a vast expanse of arable but powdery soil, had been all but ruined by deforestation and grazing, until a massive effort was undertaken to terrace the land and reforest it. Similarly, the Gorongosa National Park in Mozambique, which once suffered the multiple threats of warfare, poaching, and poaching to finance warfare, had to be restocked with certain animals—200 buffalo, for instance, and 180 wildebeest—but other species, such as lions, have re-emerged on their own.
