Survivors and Foragers: speculation on group selection and obesity

Speculation is cheap.

What if one of the variables in human weight control was activity response to caloric restriction?

Ok, so that's not too speculative. We know obese humans decrease activity when they diet. This is one reason that, in a nation of very cheap calories, so many Americans are obese. When these people diet, they are put into an involuntary lethargic state.

It's a behavior that makes lots of evolutionary sense. Throughout most of human history these people would have been survivors of famine. We can call them The Survivors.

But what if there's a distribution across the population? What if there are people who respond to caloric restriction with increased activity? That makes a sort of Darwinian sense too, particularly if you think of humans as group selected Big Brain Bees (BBBs). Think of these people as Foragers, they roam from the Hive looking for new options. In todays world, some of them are anorexics, but mostly they're just slender.

I am positive that if I knew the scientific literature on obesity, and I knew the right search terms, I would find articles exploring this model. It feels plausible that there's a range of responses to calorie restriction -- from Survivors to Foragers and everything in between.

Of course feelings are the fount of grant proposals, not of science. This is, however, a testable hypothesis. So it could turn into science.

There are implications for drug discovery. If this model were correct, the magic obesity pill would convert Survivors into Foragers. So pharmas should be looking for Foragers to study ...

Google's bicycle directions are getting scary good in MSP

A few weeks ago Google's bike directions from my home to my office were pretty good, but they did send me over a fairly narrow and crowded overpass. Still, I was impressed. It was as good as I could do at the time.

Today I remembered a really obscure hidden footpath that would be an improvement on that route. I went to Google Maps so I could provide feedback to the bicycle map team.

The route improvement was already there:

Wow.

PS. Don't get too cocky Google. Your "draft" Blogger rich text editor still can't handle European language paragraphs. My theory is it's being developed by a team unfamiliar with the paragraph.

Anthem - Putting the Hell in Health Insurance

My corporate health care insurance is administered by Anthem.

Tonight we tried to find out if a particular physician is in their coverage network.

First I tried their Account Registration. It includes a CAPTCHA test.

Why does it include a CAPTCHA test? Really you don't need to ask. Since CAPTCHA hacking software exceeds human performance, it's really a filter to eliminate humans. Particularly elderly humans who might need expensive services.

I kept failing the test. Emily checked, and I seemed to be typing the correct response. We even tried the audio test. That one would  have impressed Mephistopheles.

So Emily tried their customer service number. Voice recognition of course, no keypad entry. It couldn't understand anything she said. Her voice kept rising, but it didn't help. I tried not to laugh too much.

So I tried the web site again. This time I got a different response: "Sorry, we're experiencing technical difficulties at this time. Please try again later or contact Customer Care. Error ID: 21573301".

Terry Gilliam couldn't have done it better.

It's moments like these that make me more optimistic about the future of humanity. Our civilization is sure to collapse before we can create the sentient machines that will end us. We will be saved by our own greed and incompetence.

PS. The coup de grace came as a post-visit survey. An opportunity to provide feedback! So I started answering questions. The questions kept coming. I noticed the the scroll bar size -- I was only through 15% of what must have been 50 questions. I tried scrolling to the end and submitting. Of course that was rejected; I hadn't answered all the questions. I had to smile at the style of it; sadism with a flourish.

Update 8/27/10: There's an old joke that the best way to improve health insurance plan revenues is to put the registration office on the top floor of a building with no elevators. Only the healthy can join, so that even low rates will be profitable.

The CAPTCHA is the modern equivalent of the top floor office without elevators. In this case there was a web site failure, but I'd wager their web site is always fragile. Since Anthem has already been paid, their incentive is to deny services altogether.

The beauty of these sorts of scams is that they're emergent. They develop in the same fashion as antimicrobial resistance in bacteria, or lousy service in AT&T's flat rate data network. Entropy and funding choices provide the "mutations", the commercial market provides the "selection", the system irresistibly evolves until we get the Anthem web site.

This kind of perverse incentive is built into many systems, but it's particularly strong in the health insurance business. If we recognize and understand these processes we can work around them -- much like modern HIV therapy works with an understanding of the the virus evolves. I suspect oncology is going to go the same way -- using therapies that "guide" the "evolution" of the cancer / tumor ecosystem towards forms that may be most vulnerable to a 2nd wave treatment -- or most compatible with the life of the human "host". (I kind of like that cancer idea btw, I do hope it's really part of modern therapy.)

As a society, however, we're only in the most early stages of understanding the evolution of emergent corporate dysfunction and how to manage it.

Who does phone surveys anyway?

I'm a grateful reader of the FiveThirtyEight Blog, now hosted by the NY Times. They give everyone access to electoral data that was once available only the pros.

Of course their data is only as good as the phone survey. I've been wondering, lately, how well that is working.

We get quite a few "survey" calls. Some of them are surely legitimate, but others are ploys to raise money for campaigns. Some are probably "phishing" (identity theft) operations. Given the range of "survey" calls we get, it's not surprising that we never answer any of them.  (In fact I never had time anyway, but Emily used to be more cooperative.)

So we're not surveyed.

So how common is our reaction? I know we're very peculiar in most things, but I would imagine that the fund raising tricks and phishing exploits must turn quite a few people off of surveys.

PS. We always tell them to take us off the call list, but I doubt that does anything. We're in the 'do not call' registry anyway.

Schmidt really did sell Google's soul to Verizon

Apple could do a deal with AT&T and emerge unchanged because, of course, Steve Jobs is Satan. He is beyond mere corruption.

When Google did a deal with Verizon though, they lost everything (emphases mine) ...
Marvin Ammori: Google-Verizon Pact: Makes BP Look Good

A lot of people have been discussing the Verizon-Google pact, including venture capitalists (on NYT's Room for Debate) and Silicon Valley companies. Most people agree: Google does evil, calls it net neutrality.

Last week I wrote up a guide of the FCC negotiations on net neutrality, setting out all the loopholes, and noting that the carriers needed only one loophole to kill an open Internet. Verizon and Google announced their pact two days ago. Rather than including one loophole, they went down the checklist and included just about every loophole they could.

Maybe the most ridiculous one--which has received almost no attention--is something I didn't mention last week. It's the liability limit. The maximum fine for a violation, after all the loopholes are met, is $2 million dollars...
Fixed rate fines are one of the great scams of American government. A true fine would max out at 30% of Google's yearly revenue.

This Taiwanese video is now quite plausible.

Schmidt is a lesser version of Microsoft's Steve Ballmer. If Google doesn't dump him he'll take them down.

The Bowhead whale can live how long?!!

A graphic in Why Can't We Live Forever? (Scientific American) lists maximal lifespan of various familiar species.

The Jellyfish and Hydra are "immortal". The Galapagos tortoise can live 150 years. Humans 122, Dogs 39, Cats 36, Horse 62(!), Chimp 59(!).

There are a couple of surprises there. I didn't dream a horse could live that long. I imagine that's a bit of a problem for many horse owners. I wonder how many horses ever die a natural death, even if the average lifespan is only half that.

And, of course, the Bowhead whale can live up to 211 years.

WTF?! Where did that come from?

I found this 1999 reference, it's apparently the source for the 211 year estimate ...
... Based on these data, growth appears faster for females than males, and age at sexual maturity (age at length 12-13 m for males and 13-13.5 m for females) occurs at around 25 years of age. Growth slows markedly for both sexes at roughly 40-50 years of age. Four individuals (all males) exceed 100 years of age. Standard error increased with estimated age, but the age estimates had lower coefficients of variation for older animals. Recoveries of traditional whale-hunting tools from five recently harvested whales also suggest life-spans in excess of 100 years of age in some cases.
It turns out Bowhead Whales and Naked Mole Rats both have weirdly long lifespans  ...
... Mitoptosis can be also activated in adult postmitotic somatic cells by evolutionary conserved phenotypic adaptations to intermittent oxygen restriction (IOR) and synergistically acting intermittent caloric restriction (ICR). IOR and ICR are common in mammals and seem to underlie extraordinary longevity and augmented cancer resistance in bowhead whales (Balaena mysticetus) and naked mole rats (Heterocephalus glaber)...
So to live long and prosper spend mealtimes holding your breath rather than eating?

Not surprisingly a 2007 article advocating genome sequencing of mammals with atypical longevity ...
... we propose the sequencing of three organisms of unique interest for aging research: the naked mole-rat (Heterocephalus glaber) whose record longevity of 28.3 years makes it the longest-lived rodent (2), the white-faced capuchin monkey (Cebus capucinus) which can live 50 years (3), and the bowhead whale (Balaena mysticetus), the longest-lived mammal with estimates suggesting that it may live 200 years (4).
Hmm. Maybe we should do this sequencing before we drive all whales to extinction?

Even if the 211 year estimate is an exaggeration these whales live much longer than I'd imagined. I'd have guessed 40 years, but they're still young adults at that point.

Until this minute I was skeptical that there was really much room to slow the human aging process. Now it feels inevitable. Not likely in my lifespan, but maybe the future of my children or their children.

The Corporation - what next?

In my seventh year within the fascinating, feudal, emergent machinery of a classic publicly traded corporation I volunteered to write a white paper about supporting internal collaboration for shared services. I wrote a post in 2008 asking about examples of systems to enable such collaboration.

I can't share the final paper here, but the conclusions were unsurprising. I think they are true of any corporation of significant size.

In the absence of internal markets, contracts, and currencies, true corporate collaboration requires either accounting system reorganization, or serious executive pressure, or some sort of baby-sitting coop style internal currency. All of these things are very hard to do; ironically collaboration outside the corporation is easier (see also - outsourcing) [3]. For example, executive power, like Presidential power, is a limited currency that must be used sparingly. [1]

I felt when I wrote the paper that I was walking old ground, but my real expertise is in health care and more esoteric domains. I didn't know how to follow this trail.

Later I learned I was intersecting the path of Ronald Cause and his 1937 paper The Nature of the Firm [3]. Alan Murray describes the paper in a recent WSJ article on the future of the corporation ...
The End of Management - Alan Murray - WSJ.com
... British economist Ronald Coase laid out the basic logic of the managed corporation in his 1937 work, "The Nature of the Firm." He argued corporations were necessary because of what he called "transaction costs." It was simply too complicated and too costly to search for and find the right worker at the right moment for any given task, or to search for supplies, or to renegotiate prices, police performance and protect trade secrets in an open marketplace. The corporation might not be as good at allocating labor and capital as the marketplace; it made up for those weaknesses by reducing transaction costs.
Mr. Coase received his Nobel Prize in 1991—the very dawn of the Internet age. Since then, the ability of human beings on different continents and with vastly different skills and interests to work together and coordinate complex tasks has taken quantum leaps. Complicated enterprises, like maintaining Wikipedia or building a Linux operating system, now can be accomplished with little or no corporate management structure at all...
I wasn't quite following Ronald Coase however; I was intersecting him. Seventy years after his paper was published, I came from a world where intra-corporate transaction costs were higher than extra-corporate costs. By 2007 collaboration within a typical large corporation had become more difficult than similar collaboration with an external agent.

Why did this happen? That's a rather interesting question. I expect there are publications on it, but they'd be hard for me to find. I wouldn't be be surprised if the costs of intra-corporate transactions are higher in 2007 than in 1937, and that the costs of extra-corporate transactions are substantially lower. The balance has shifted.

So why does the Corporation persist?

Well, for one thing, entrenched institutions are like cities of the northeast or trees tangled in the tropical canopy. They don't collapse overnight just because their sustaining systems are gone. The publicly traded corporation is deeply embedded in American law (including taxation law), accounting standards, international treaty, and politics (senatorial ownership). It's going to be around for decades to come.

Beyond mere inertia, however, Corporations are awfully good at economic warfare; a mode of operation more in the province of Macchiavelli's The Prince than standard economics texts [4]. Microsoft was once the master of this economic warfare, Intel still is. This mode of operation actually destroys customer value, but it's not going away.

Even though the 20th century Corporation will persist, but better and for worse, it's clear we're in one of those times of cranky dissatisfaction where the ancient Monster of the Market is looking vulnerable. We can at least hope there will alternatives.

Murray's sources don't know what those alternatives will be, and they seem reluctant to speculate. His prescriptions are a rehash of the usual management book pap - "agile, flexible, ruthless, cut their losses, lots of bets, Google [5], inspire, entrepreneurs, push decision-making down, wisdom of crowds, feedback, change, innovation, adaptability" , blah-blah-blah.

For my part I've been looking for good speculation since 2006, and I haven't come across much. I wrote up some of my thoughts last June, and some speculations by Iain Banks yesterday. I'm behind on reading Clay Shirky's 2008 book, I suspect I'll have some follow-up posts when I do that.

I'm guessing that we'll somer interesting variations emerge over the next decade. Some of them will resemble Apple (Singaporean model of the brilliant tyrant in what's effectively a public-private corporation), some Google (natural selection - creates sharks and tapeworms), and some may come from China (what is Foxconn [6]?).

I'm hopeful that within a decade I'll be able to invest in privately held companies where the owners have major organ systems in the game. I wouldn't mind working for or owning a part of one of those companies.

Interesting times.

[1] I concluded that any collaboration must be informal. This can work because are many employees will, for a minuscule amount of recognition and commendation, happily share their work. (Unless their private knowledge becomes job security - which is a bit of a big caveat.)
So the question becomes how best to enable informal networks of internal collaboration at a time when personal connections within corporations have greatly weakened.
If I were (heaven forfend) running a publicly traded company I would require my IT department to choose a network sharing environment that supported search and discovery, and I'd train people to use it. I think you could actually do this on a large scale using an improved version of Microsoft SharePoint wiki (the rest of SP is an unredeemable disaster) and its companion search and discovery services.
This is hard stuff to do in hard times of course, and in easy times it does not seem necessary.

Troubled capitalism: The corporate entity

Iain M. Banks sticks his ideas into his fiction as digressions. They're often quite interesting digressions.

Transition is one of his books with several digressions. It's a powerful book, but it's not an easy book (my fave reviews: 1, 2, 3). It reads like a mixture of his literary fiction (written as Iain Banks) and his science fiction (written as Iain M Banks).

Since Transition came out in 2009, after the great crash of 2008, and since Banks is a critic of capitalism, it's not surprising that one of his digressions concerns the problems of a world with American style capitalism [1] ....
... this was a Greedist world, a world where the untrammelled pursuit of material wealth and the virtues of money itself were extolled, venerated and even worshipped...
... There are as many types of capitalism as there are types of socialism – or any other ism for that matter – but one of the major differences – a major difference founded on what appears to be a minor detail – between whole bundles of ostensibly fully capitalist societies centres (indeed, depends) on whether commerce is governed by private firms and partnerships, or by limited companies.
... the invention and acceptance of the limited company means people can take big risks with money not their own and then – if it all goes wrong – lets them just walk away from the resulting debts, because the company is somehow regarded as being like a person in its own right, so that its debts die with it (not the sort of fairy story a partnership is allowed to get away with).
It’s a piece of nonsense, really, and I used to wonder that legislatures anywhere bought into this blatant fantasy and agreed to give it legal house room. But that was just me being naive, before I realised that there was a reason why it always dawned on all those ambitious, powerful gents in all those various legislatures that this ludicrous hooey might actually be quite a good idea.
Anyway, limited company worlds often progress faster than other types, but always less smoothly and reliably, and sometimes disastrously. I’ve looked into it and frankly it just isn’t worth it, but you can’t tell that to anyone caught up within the seductive madness of the dream; they have the faith, and are forever relieved by the invisible hand...
I'm sympathetic to the general idea that there's something broken with the publicly traded company. I haven't, however, taken that to mean that there's also something broken with the very idea of the corporation personified.

I'll have to give it some thought.

[1] I started typing from the book, then it occurred to me to Google some key phrases. That's how I discovered that there is a Russian web site that contains transcriptions of at least this book - and probably others. It is, of course, completely illegal. The site is entirely in Russian, but Google found the book within it, including this digression.

Public education in America - Primary and Secondary

On the same day Gail Collins tells us about American aristocrats seeking power, Bob Herbert reminds us (yet again) of an inconvenient truth [5] ...
... The Schott Foundation for Public Education tells us in a new report that the on-time high school graduation rate for black males in 2008 was an abysmal 47 percent, and even worse in several major urban areas — for example, 28 percent in New York City....
...More than 70 percent of black children are born to unwed mothers... Black men ... have nearly a one-third chance of being incarcerated at some point in their lives...
...White families are typically five times as wealthy as black families. More than a third of all black children are growing up in poverty...
Those are bad numbers on several fronts, though it's worth noting that 66% of Icelandic infants are born to unmarried mothers and in 2007 60% of babies born to all American women in their 20s were out of wedlock.

Black Americans are not unique on the educational front either ...
The Dropout/Graduation Crisis Among American Indian and Alaska Native Students — The Civil Rights Project at UCLA
... Data from 2005 is drawn from the seven states with the highest percentage of American Indian and Alaska Native students as well as five states in the Pacific and Northwestern regions of the United States ... On average, less than 50% of Native students in these twelve states graduate each year.
Public education isn't even working that well at our above average elementary school and state of Minnesota (in 2007 the St Paul school District was ... "30 percent Asian [2], 30 percent black, 26 percent white and 13 percent Hispanic" [1]) ...


Herbert is right that American blacks, and especially black men, are in serious trouble. At least when it comes to education though, they're not alone. Their trouble is a leading indicator for a lot of others.

So maybe we should beat up on the teachers? I can think of many ways reading and math [4] education and student assessment could be improved, but, at least for the particular St Paul school in the above graphic, I believe the teachers are pretty good to excellent. Some teacher-kid-parent combinations work better than others, but those teachers aren't the problem.

Ok, maybe we should beat up on the parents? Oh, wait, I'm a parent. Skip that one.

Maybe we should get better students? That does work. They used the better student method to improve test schools in Bush era Houston and in Mississippi. Health providers have long used similar techniques to improve health care outcomes. True, this is the same way wolves contribute to the health of caribou, but we don't eat the losers. We house them.

Hmm. So we can't beat up the teachers, we can't pummel the parents, and eliminating the weak kids is kind of cheating. So what's left?

Maybe we need to rethink the goals of our educational enterprise. Maybe, in a turbulent world of rapid change, we need to have different options for different kids. In 2020 it's not hard to imagine that a skilled gardener might have better employment opportunities than an accountant or a dermatologist.

Maybe we need to restart with the end in mind.

[5] Glenn Loury, writing for the Boston Review in 2007 about American imprisonment, said much the same thing ...
... a central reality of our time is the fact that there has opened a wide racial gap in the acquisition of cognitive skills, the extent of law-abidingness, the stability of family relations, the attachment to the work force, and the like. This disparity in human development is, as a historical matter, rooted in political, economic, social, and cultural factors peculiar to this society and reflective of its unlovely racial history: it is a societal, not communal or personal, achievement....
Update 9/4/10:

This post on how bad statistics led to a blunder in evaluating small schools is very relevant. With most Pay for Performance initiatives mall schools are randomly rewarded and randomly punished for normal fluctuations in the composition of the student body. The same thing will happen to small health care facilities.

How we know humans have not yet adapted to the digital world

I still often read that "young people" are naturally "digital".

Writing as a definitely-not-young person I don't see it. I've never seen it.

I did see, before phones had qwerty keys, that teens were very good at texting using numeric keypads. In the later tactile qwerty era they were very good at typing with two thumbs. Young motor cortices and cerebella just pound geezer brains - even if we don't mention gaming. (In the iPhone era, however, the keyboard advantage seems more modest.)

What haven't seen are major improvements in the abstract domain of interacting with knowledge, information, and early AI systems. If young people were naturally digital then sheer demand would force Gmail to let us edit subject lines. Hasn't happened.

They are certainly not better programmers than the geezers I know. Coding used to be something of a young man's game, but now it takes so long to learn that it's becoming almost a middle-aged game.

Our brains evolve much more quickly than we used to think, but they don't switch tracks in a generation. Computer adaptation is cultural, and we're still in the early stages. We have a lot of cultural evolution to go through before we get maximal benefit from the IT infrastructure of even 2010 -- much less the infrastructure of 2020.

Which means that we'll be in a whitewater world of technology transition for decades to come.

Lessons from a wrecked Toro Personal Pace recycler lawn mower

I'm not a motor guy. I prefer bikes, skinny skis, kayaks, skates, feet - most anything else. Even so, I've kept my usually pre-owned lawn mowers going for a few years.

Until I got fancy and bought a new, monstrous, Toro "guaranteed to start" "Personal Pace" self-propelled "recycler" mower with a "Briggs and Stratton" engine. I used it for about 1 season before I confirmed this chap's experience:
Toro Personal Pace Recycler Mower 20073 Reviews. Buying Guides & Consumer Product Reviews - Epinions.com
Pros: Easy to move around not much more to say about Pros.
Cons: Check the oil often. I'm leaving this one at the curb and buying a Honda!
I purched my Toro a year ago. Make sure you check the oiloften I checked it once in the year I owned it (like I did with my Honda I have had for 15 years) and the engine seized. save your money and buy a Honda!...
I probably used it about 8 times. Did I mention I'm not a lawn guy? I'd have probably checked the oil come the fall, but it never got there.

So I'm out $400 or so for the mower, - plus $35 for the checkup because lack of oil isn't quite covered by warranty. The manual, by the way, says to "check oil before each use or daily". I kind of missed that bit.

I get annoyed when I waste $10 on a bad book, so I'm definitely looking for lessons from this one. The one silver lining was I despised the mower. It was heavy, clumsy, lousy on hills, and overall it was designed for cutting estate lawns rather than our weeds.

Here are my early lessons. I'm still looking to add more ...
  1. Never buy anything from Toro or Briggs and Stratton. I think I can remember that one.
  2. Don't buy anything without research. I'm used to researching bikes, cameras, cars and so on, but I thought I could go to a reputable place and just pick up a mower. Wrong.
  3. Buy the simplest stuff possible. I didn't need the "personal pace" feature, I didn't need the recycler. I did need a minimal maintenance device. The store I went to didn't have anything simpler.
  4. Never buy anything over $50 in a hurry. I should have left the store when I didn't see what I wanted, instead I bought what they had.
  5. I'm really not an engine guy.
Now I'm researching the alternatives. I like the look of this Gardena LiOn mower (high-end cylinder motor with LiOn boost), but I'm definitely doing my research first ...

Update: My Amazon review. Most of the reviewers do like this mower.

Why I like Krugman ...

I like Krugman because he makes testable predictions ...
Liquidity Preference And Loanable Funds, Revisited - Paul Krugman Blog - NYTimes.com 
A brief revisiting of the issues I raised more than a year ago regarding alternative views of interest rates.

This was never a question of simply forecasting what was going to happen to rates. It was about what would drive rates.

The view of Ferguson and others, back then, was that government deficits would drive up interest rates, choking off recovery. I and others argued that this was bad macroeconomics: interest rates would rise if and only if recovery took place. More specifically, short-term rates would stay near zero as long as the economy was deeply depressed; long-term rates would depend on expectations about the future of short rates, and hence on prospects for recovery.

So the key point is not the fact that rates are now considerably lower than they were when that debate took place; it’s the fact that rates have fluctuated very much with optimism about recovery, never mind the deficits.

In fact, if you had a naive loanable funds view, you’d expect the recent downgrading of expectations to drive rates up, not down — after all, a weaker economy means bigger deficits. But the opposite has, in fact, been happening.

The bottom line is that events have utterly confirmed one view, utterly rejected the other. Too bad such things don’t count in politics.
Testable predictions are a fundamental distinction between science and mere scholarship.

Iraq, Afghanistan, Taliban and Patriarchy

Family and friends of a young Afghan couple stoned them to death. Did the girl's father throw a stone? Will his sleep be forever tortured?

Humans are revolting. We should really start over with dogs.

Pending a better sentient animal, however, while stonings, whippings, and mutilations of women are momentarily in the public eye, it is worth resurrecting the old question ...
What fraction of the Talib/Afghan/Saudi/Wahabi cross-gender resistance to the American agenda comes from a desire to maintain extreme patriarchy and male power?
There are, of course, many reasons for anyone to resist the (fungible) American agenda, and many reasons to question the value and expression of that agenda. Those are good discussions, but they don't change my question. (Note that the resistance I'm referring to is cross-gender; women in these cultures are often strident supporters of their current cultural milieu.)

My guess is that maintenance of patriarchy is the strongest single reason for resisting American interventions including education and health care. If we could quantify contributing factors, I bet 2/3 would fall under patriarchy.

I wonder if there's any way to objectively measure this. It might be important to understand, as we enter Year 10 of the Long War.

Another nail in the coffin for the Alzheimer's amyloid hypothesis

Researchers bet careers, and pharmas bet billions, that amyloid plaques caused neuronal dysfunction in Alzheimer's disease. If the plaques could be prevented, you could prevent the disease.

Those bets have been going bad over the past four years. Today Lilly lost another bundle ....
Lilly Halts Alzheimer’s Drug Trial - Prescriptions Blog - NYTimes.com
... semagacestat, did not slow progression of the disease and was associated with a worsening of cognition and the ability to perform the tasks of daily living....
... The failures, and particularly this newest one by Lilly, could raise questions about the validity of the prevailing theory about Alzheimer’s, which is that the disease is caused by the accumulation of so-called amyloid beta plaques in the brain. 
 Lilly’s drug was designed to reduce the body’s production of the plaques by inhibiting the activity of an enzyme, called gamma secretase, that is believed to play an important role in formation of the plaque...
The contrary hypothesis was that the characteristic amyloid plaques of Alzheimer's disease were either a consequence of the disease process, or perhaps even some sort of protective measure. That hypothesis has been getting more support.

This latest result is just one example of all the recent bad news on delaying age-related dementia in general, and Alzheimer's disease in particular. We now know that "mental exercise", "social prophylaxis" and so on don't delay disease onset. We have shown that most treatment medications are, at best, marginally effective and poorly tolerated. We have no preventive meds -- estrogen, statins, non-steroidals and so on all are unimpressive.

We do know that head injuries are bad - worse than we imagined. Not only are concussions associated with Alzheimer's dementia, they're also associated with motor neuron disease. Most contacts sports, including American football and "soccer" will look very different in 10 years.

We believe, bizarrely, that exercise really does preserve the brain. We don't have a solid mechanism for that.

We also have tests that can diagnose Alzheimer's early, which is a good way to ensure you'll never be able to buy long term care insurance. Otherwise the tests look pretty pointless.

We need some good news. Forget the blather about social security -- that's not the crisis. That's just a GOP distraction. The crisis is pre-dementia and dementia in an aging post-industrial America.

Lessons from Strong Fathers, Strong Daughters

I learned a very valuable lesson from Meg Meeker's book "Strong Fathers, Strong Daughters".

Always read the 1 star reviews (mine). [1]

Always, always, always.
