Jacob Sullum on the legacy of Thomas Szasz

Filed under: Health, Law, Liberty — Tags: , , , — Nicholas @ 08:48

Jacob Sullum‘s post on the influence the late Thomas Szasz had and continues to have:

The idea that psychiatry became scientifically rigorous soon after Szasz first likened it to alchemy and astrology is hard to take seriously. After all, it was not until 1973 that the American Psychiatric Association (APA) stopped calling homosexuality a mental disorder.

More often, psychiatry has expanded its domain. Today it encompasses myriad sins and foibles, including smoking, overeating, gambling, shoplifting, sexual promiscuity, pederasty, rambunctiousness, inattentiveness, social awkwardness, anxiety, sadness, and political extremism. If it can be described, it can be diagnosed, but only if the APA says so.

[. . .]

For more than half a century, Szasz stubbornly highlighted the hazards of joining such a fuzzy, subjective concept with the force of law through involuntary treatment, the insanity defense, and other psychiatrically informed policies.

Consider “sexually violent predators,” who are convicted and imprisoned based on the premise that they could have restrained themselves but failed to do so, then committed to mental hospitals after completing their sentences based on the premise that they suffer from irresistible urges and therefore pose an intolerable threat to public safety. From a Szaszian perspective, this incoherent theory is a cover for what is really going on: the retroactive enhancement of duly imposed sentences by politicians who decided certain criminals were getting off too lightly — a policy so plainly contrary to due process and the rule of law that it had to be dressed up in quasi-medical, pseudoscientific justifications.

Szasz specialized in puncturing such pretensions. He relentlessly attacked the “therapeutic state,” the unhealthy alliance of medicine and government that blesses all sorts of unjustified limits on liberty, ranging from the mandatory prescription system to laws against suicide.

A brief obituary notice for Thomas Szasz:

Thomas Stephen Szasz, M.D., 92, died at his home in Manlius, N.Y. on September 8, 2012. He was born in Budapest, Hungary in 1920, and emigrated to the United States in 1938. He graduated the University of Cincinnati with an undergraduate degree in physics in 1941, and as valedictorian of the medical school in 1944. After medical internship at Boston City Hospital and psychiatry residency at the University of Chicago, he pursued psychoanalytic training. [. . .] He argued that what are called mental illnesses are often better described as “problems in living,” and he opposed involuntary psychiatric interventions. His reputation in defense of these principles was launched in 1961 with The Myth of Mental Illness. He published 35 books, translated into numerous languages, and hundreds of articles in the subsequent 50 years.

Matt Ridley reviews a new book by Moises Velasquez-Manoff:

In a remarkable new book, “An Epidemic of Absence,” Moises Velasquez-Manoff draws together hundreds of such studies to craft a powerful narrative carrying a fascinating argument. Infection with parasites prevents or ameliorates many diseases of inflammation. The author briefly cured his own hay fever and eczema by infecting himself with hookworms-before concluding that the price in terms of diarrhea and headaches was too high.

I’ve touched on the “hygiene hypothesis” in these pages before. In its cartoon form the argument-that in a clean world our immune system gets bored and turns on itself or on harmless pollen-isn’t very convincing. But Mr. Velasquez-Manoff makes a far subtler, more persuasive case. Parasites have evolved to damp our immune responses so that they can stay in our bodies. Our immune system evolved to expect parasites to damp it. So in a world with no parasites, it behaves like a person leaning into the wind when it drops: The system falls over.

Moreover, just as brains outsource much of their development to the outside world-the visual system is refined by visual input, the language system can only develop in a language-using society — so the immune system seems to have happily outsourced much of its regulation to friendly microbes. Without them, the immune system becomes unbalanced.

[. . .]

One of Mr. Velasquez-Manoff’s most surprising chapters is on autism, a disorder that almost exactly parallels asthma in its recent rise among affluent, urban, mainly male, disproportionately firstborn people. Better diagnosis explains perhaps half the rise, but the brains of people with autism are often inflamed, and there’s anecdotal evidence that infection with worms or viruses can tame autistic symptoms, at least temporarily.

It’s time to retire the pop-sci term “Junk DNA”

Filed under: Health, Science — Tags: , , — Nicholas @ 08:42

In the Wall Street Journal, Gautam Naik and Robert Lee Hotz report on the most recent discoveries about the human genome:

The new insight is the product of Encode, or Encyclopedia of DNA Elements, a vast, multiyear project that aims to pin down the workings of the human genome in unprecedented detail.

Encode succeeded the Human Genome Project, which identified the 20,000 genes that underpin the blueprint of human biology. But scientists discovered that those 20,000 genes constituted less than 2% of the human genome. The task of Encode was to explore the remaining 98% — the so-called junk DNA — that lies between those genes and was thought to be a biological desert.

That desert, it turns out, is teeming with action. Almost 80% of the genome is biochemically active, a finding that surprised scientists.

In addition, large stretches of DNA that appeared to serve no functional purpose in fact contain about 400,000 regulators, known as enhancers, that help activate or silence genes, even though they sit far from the genes themselves.

The discovery “is like a huge set of floodlights being switched on” to illuminate the darkest reaches of the genetic code, said Ewan Birney of the European Bioinformatics Institute in the U.K., lead analysis coordinator for the Encode results.

Our conflicted feelings about athletes “juicing”

Filed under: Football, Health, Science, Sports — Tags: — Nicholas @ 08:13

In a sport that most people don’t care about unless a local player is doing well internationally (competitive cycling, for example), a scandal over performance enhancing drugs is a good opportunity to make noises about the “purity of the sport” and demand major sanctions against those who cheat. However, as Jim Souhan points out at the Star Tribune, we’re rather good at turning a blind eye to the same thing in sports we care more about:

The advent of the NFL season will provide a respite from sports riddled with performance-enhancing drugs, such as baseball and cycling.

If you can read that sentence without laughing, you are one naive fan.

We know many baseball players cheated in the ’90s and early 2000s, and we know some cheat today. For every Melky Cabrera who gets caught there must be dozens, if not hundreds, who are smart enough to avoid testing positive in a system that is easy to beat.

We know cyclists cheat. The evidence is overwhelming. When Lance Armstrong pretended to take a principled stand by abandoning his legal fight to defend himself, he was avoiding facing public testimony by a squadron of former teammates. Now another former teammate, Tyler Hamilton, has written a book in which he details his own, and Armstrong’s, cheating, and other former Armstrong associates are speaking openly about his PED use.

[. . .]

If Armstrong could avoid testing positive for PEDs while winning the Tour de France seven times, what does that tell us about the National Football League, a sport filled with the biggest, strongest, fastest and most explosive athletes in our society?

That’s right: The NFL must be stuffed with performance enhancers.

The difference is that we don’t care.

True-but-misleading factoid: “7 kg Of Grain To Make 1 kg Of Beef”

Filed under: Economics, Environment, Food, Health — Tags: — Nicholas @ 00:05

Tim Worstall on the mis-use of a vegetarian-friendly data point:

I asked Larry Elliott where the number came from and was sent this from Fidelity Investments (not online so far as I know).

    The demand for more protein has a significant knock-on impact on grain demand. Livestock is reared on grain-feed, making production heavily resource intensive. Indeed, it takes 7 kilograms of grain to produce just 1 kilogram of meat. As demand for meat rises, this increases the demand for and prices of feedstock — these increased costs of productions flow back to the consumers in the form of higher meat prices. Adding to the upward pressure on feedstock price and much to the dislike of livestock farmers, have been US environmental regulations (the Renewable Fuel Standard) that require a proportion of corn crops be used for the production of bio-fuel.

So, case closed, right? We all need to give up eating meat to save Mother Gaia? Not necessarily. The numbers given are accurate, but only in a particular context: that of raising meat for the US (and, probably, Canadian) market. The rest of the world doesn’t do it this way:

It is only in US or US style feedlot operations than cattle are fed on this much grain. Thus the equation is useful if you want information about what is going to happen with US cattle and grain futures: for that’s the general production method feeding those cattle futures. But very little of the rest of the world uses these feedlots as their production methods. I’m not certain whether we have any at all in the UK for example, would be surprised if there were many in the EU. Around where I live in Portugal pigs forage for acorns (yes, from the same oak trees that give us cork) or are fed on swill, goats and sheep graze on fields that would support no form of arable farming at all (they can just about, sometimes, support low levels of almond, olive or carob growing). Much beef cattle in the UK is grass fed with perhaps hay or silage in the winters.

My point being that sure, it’s possible to grow a kilo of beef by using 7 kilos of grain. But it isn’t necessary. The number might be useful when looking at agricultural futures in the US but it’s a hopelessly misguiding one to use to try and determine anything at all about the global relationship between meat and grain production. And most certainly entirely wrong in leading to the conclusion that we must all become vegetarians.

Which brings us to the lesson of this little screed. Sure, numbers are great, can be very informative. But you do have to make sure that you’re using the right numbers. Numbers that are applicable to whatever problem it is that you want to illuminate. If you end up, just as a little example, comparing grain to meat numbers for a specific intensive method of farming really only used in the US then you’re going to get very much the wrong answer when you try to apply that globally.

A bit of common sense in food news

Filed under: Environment, Food, Health, Media — Tags: , , , — Nicholas @ 10:39

Rob Lyons reviews a new book by Mike Gibney that attempts to bring some common sense back to counteract the epidemic of fear-mongering about food:

Given much of the popular discussion about food, it would be easy to despair that we face a future where half the world’s people starve to death while the other half drown in their own fat. The words ‘new food research’ in a news report are often just the lead into another sorry tale about how some aspect of what we eat is going to kill us or how some specific food will provide ‘miracle’ protection against the chronic illnesses of our age.

Professor Mike Gibney’s new book, Something to Chew On, is a welcome step back from all this noise, offering an expert take on many of these claims. Gibney is director of the Institute of Food and Health at University College Dublin and has served on many national and international advisory committees.

[. . .]

Take pesticides, for example. Many people are prepared to pay through the nose to buy organic food which is free of artificial pesticides. But as Gibney points out, those people are actually consuming a far greater weight in natural, plant-produced pesticides that are potentially every bit as cancer-inducing as modern chemicals. ‘Nature abounds with chemicals which, while beautifully natural, are nevertheless risk-laden’, he says, from the deadly poison ricin, found in castor beans, to substances in fava beans that induce a lethal form of anaemia in some susceptible people. The key is in the dose: for both natural compounds and their highly regulated artificial counterparts, the amounts that we actually eat are too small to represent any threat to health.

Indeed, Gibney goes on to make mincemeat of all of the claims made for organic foods: they don’t taste better than conventional crops, they offer no nutritional advantage, and, by being less productive, they are actually wasteful of land. That’s hardly environmentally friendly.

Part of the reason we get such overblown nutritional and health “advice” from the media is the difficulty of conducting nutrition research:

While trying to figure out the effect of eating, or not eating, a particular kind of food on cancer or heart disease, for example, there are numerous confounding factors that get in the way of drawing robust conclusions. People lie about what they eat or simply don’t record it accurately; factors that look like cause and effect can turn out to be mere associations. Even finding enough subjects to look at the effect of diet on a relatively unusual disease, like ovarian cancer, can be very difficult.

[. . .]

The truth is that every study’s results need to be treated with caution and there needs to be open-mindedness about other possible explanations. While it is relatively easy to see the effects of vitamin deficiency, for example, for the most part nutrition research moves forward on the basis of a lot of evidence that is unsatisfactory in one way or another. The endless stream of claims that red meat, sugar, eggs and myriad other foodstuffs cause harm should be treated with an almighty pinch of salt (as do claims about salt, for that matter).

Along the way, Gibney offers his thoughts on personalised nutrition — the possibility of creating diets specifically suited to our own DNA — and epigenetics — the idea that different elements of our DNA can be switched on or off by environmental factors in the womb or the first years of life. He also offers a Jacques Cousteau-like tour of the human gut. Did you know there are 10 times more bacteria living in our guts — 100 trillion — than there are cells in the human body? Did you know those bacteria can sometimes switch on or off changes in our bodies to suit their own needs? Gibney describes our relationship to this mass of bugs as a permanent state of ‘armed peace’, with mutual benefits to both parties: body and bacteria.

Rehabilitating Florence Nightingale’s reputation

Filed under: Britain, Health, History, Military, Russia — Tags: , , , , — Nicholas @ 08:31

History Today has a defence of the much-maligned Florence Nightingale:

Jamaican-born Mary Seacole (1805-81), voted top of the list of the 2004 ‘100 Great Black Britons’ poll, is now slated to replace Florence Nightingale (1820-1910) as the true ‘heroine’ of the Crimean War. She is to be honoured as no less than the ‘Pioneer Nurse’ with a massive statue to be erected at St Thomas’ Hospital in London. This in spite of the strong links between Nightingale and the hospital, her base for over 40 years. It was there she established the first secular school for nurses in 1860 with funds raised in her name for her work in the Crimean War during the conflict of 1854-56. The Nightingale School operated for over a century from the hospital, whose redesign in the 1860s Nightingale also influenced.

[. . .]

The campaign promoting Seacole over Nightingale builds on 30 years of books, articles and films denigrating the latter. While she always had detractors, the serious assault on Nightingale’s reputation can be dated to 1982, with the publication of the Australian historian F.B. Smith’s Florence Nightingale: Reputation and Power (Croom Helm, 1982). The next major hit came in 1998 with Florence Nightingale: Avenging Angel (Constable, 1998) by a retired management consultant Hugh Small, which argues that Nightingale was actually responsible for the high death rates of the Crimean War and had a nervous breakdown as a result when she supposedly recognised this. Neither claim is supported by any serious documentation. Social media goes even further: see Facebook ‘Florence Nightingale was a Murdering Bitch’, later renamed ‘Florence Nightingale: The World’s Worst Nurse’, where she is described as a ‘deluded power hungry bitch’, who ‘looks like an uptight bitch’, so that ‘the day she died’ was ‘the best thing that ever happened to the field of nursing’.

[. . .]

The French were the instigators of the Crimean War, sent more troops and were better prepared than the British. Their death rates were lower in the first year. But the British government learned from the commissions it sent out and made enormous changes. British death rates fell dramatically, from 23 per cent in the first winter to 2.5 per cent in the second — no greater than deaths among soldiers in peacetime barracks in London, as Nightingale proudly showed in a chart. In contrast, the French (lower) 11 per cent death rate in the first winter, rose to 20 per cent in the second winter. Since the French were late in publishing their statistics, neither Nightingale nor the royal commission could use them for comparison. However French doctors themselves credited the British reforms for their superior performance. Once they were properly cleansed and functioning Nightingale was proud of the Crimean hospitals. In her own charts she separated the two periods, before and after the sanitary and supply commissions, to emphasise the crucial role they played in reducing mortality.

Her analysis of what went wrong was widely accepted and led to major changes to health care in the British Army. The ‘Nightingale Fund’ raised in her honour for that work paid for the training school at St Thomas’, which led to raising nursing to the level of a profession throughout much of the world. Her experience of the war, and her reputation and research as a result of it, grounded all the social and public health work she did for the rest of her life. Her vision for health reform included bold statements, such as the belief that the poor should receive as good quality hospital care as private patients and warnings as to the dangers of hospital acquired infections. Nightingale, in short, is no mere historical figure. Her lamp should not be retired but shone brightly onto the hospital and health care problems of today.

Yet another factor in obesity

Filed under: Food, Health, Science — Tags: , — Nicholas @ 00:09

“I want to say one word to you. Just one word.” Antibiotics.

We aren’t single individuals, but colonies of trillions. Our bodies, and our guts in particular, are home to vast swarms of bacteria and other microbes. This “microbiota” helps us to harvest energy from our food by breaking down the complex molecules that our own cells cannot cope with. They build vitamins that we cannot manufacture. They ‘talk to’ our immune system to ensure that it develops correctly, and they prevent invasions from other more harmful microbes. They’re our partners in life.

What happens when we kill them?

Farmers have been doing that experiment in animals for more than 50 years. By feeding low doses of antibiotics to healthy farm animals, they’ve found that they could fatten up their livestock by as much as 15 percent. You can put the antibiotics in their feed or in their water. You can give the drugs to cows, sheep, pigs or chickens. You can try penicillins, or tetracyclines, or many other classes of antibiotics. The effect is the same: more weight.

It seems reasonable to assume that this effect is also true for humans. And we dose ourselves with antibiotics far more than we should (often for things that do not respond to antibiotics at all … a twist on the placebo effect). In addition, many of the animals we raise for meat are regularly dosed with antibiotics.

For now, two things are clear. First, antibiotics have done a huge amount of good in treating bacterial infections and if we’re even talking about reducing their use, it’s because we have the luxury of health that they have provided. Second, they are clearly overused: prescribed for illnesses that they have no power over, and used to fatten livestock that aren’t sick. Currently, on average, every American child gets a course of antibiotics ever year.

The overuse of antibiotics has fuelled the rise of antibiotic-resistant bacteria, but their impact on our beneficial bacteria could be equally detrimental. Blaser has been vociferously banging on this drum for years. As he wrote in a comment piece for Nature, “Antibiotics kill the bacteria we do want, as well as those we don’t… Overuse of antibiotics could be fuelling the dramatic increase in conditions such as obesity, type 1 diabetes, inflammatory bowel disease, allergies and asthma… We must make use of the available technology to protect and study our bacterial benefactors before it is too late.”

The historical “locavore” diet: seasonal gruel and mush

Filed under: Environment, Food, Health, History, Media — Tags: , — Nicholas @ 09:40

sp!ked has an article by authors Pierre Desrochers and Hiroko Shimizu, on the disadvantages of the true locavore diet:

Perhaps the most ludicrous claim made by some ‘locavores’ — activists who argue that food produced near final consumers is superior in a myriad of ways to distant imports — is that the globalised food-supply chain is guilty of crimes against seasonality. Limiting our intake of fresh produce to whatever can be obtained locally at certain times of the year (and preserving the surplus for the remainder), we are told, will not only help atone for agri-business’ fossil fuel-driven ways and constrain us to live within regional ecological limits, but it will also make fresh local food more enjoyable when it is available. As one locavore puts it, ‘deprivation leads to greater appreciation’.

The emphasis on local seasonality by food activists, however, is problematic on several counts. For instance, why do militant locavores limit themselves to local seasonality when they could further insist on truly ‘native’ produce and livestock? Seen in this light, North American agriculture should be essentially limited to turkeys, farmed salmon and a few other fish and shellfish, sunflowers, blueberries, cranberries, Jerusalem artichokes and some varieties of squashes. (Though the really hardcore North American locavore could go even further by reverting to problematic native crops such as sumpweed, goosefoot, knotweed, maygrass and little barley that were replaced about one thousand years ago by Mexican imports such as corn and beans.)

Basic logic aside, limiting our food intake to local productions is a one-way ticket to chronic famines and malnutrition. Having in most cases no direct experience with massive crop failures, locavores typically ignore the historical and contemporary toll taken by factors ranging from droughts, floods, heavy rains and frost to hail, windstorms, earthquakes and tsunamis, to say nothing of insect pests, rodents, soil erosion and plant and animal diseases. Yet, the historical evidence on the issue is unequivocal. It was only the development of cost-effective long-distance transportation (primarily the railroad and the steamship) that finally eradicated famines through the large-scale movement of foodstuff from regions that had experienced good harvests to those that had struggled with mediocre ones.

“The good old days” were actually pretty crappy for most

Filed under: Books, Economics, Environment, Food, Health, History, Media — Tags: — Nicholas @ 09:22

An excerpt from The Locavore’s Dilemma by Pierre Desrochers and Hiroko Shimizu in the National Post:

To a locavore, food in the future should be created pretty much like it was in the not-so-distant past: produce and animals raised lovingly in urban backyards, turning domestic waste into hearty dishes. Farmers’ markets in every small town and city neighbourhood, where people rediscover the joys of real food and get reacquainted with one another. The rebuilding of small-scale slaughterhouses and canning factories to serve area producers and foster the preservation of local food items for consumption in the off-season.

Ideally, this local system would also be built on seeds saved from the previous harvest rather than purchased from giant corporate seed producers; ancient “heirloom” cultivars developed before synthetic fertilizers and pesticides became available and that, as a result, are better able to seek nutrients in the soil, don’t require any chemicals and are naturally resilient to drought and pests (“If it’s old seed, it’s good seed!”); and “heritage” animal breeds better able to withstand diseases and harsh environments and grow fat and happy on pastureland alone. Pest control would be achieved through traditional “natural” products based on plants and minerals; manual labour, such as crushing or picking bugs and larvae off foliage or removing weeds by hands; and biological control methods, such as introducing exotic animals, insects and bacteria that feed on invasive pests. Finally, factory-made fertilizers would be replaced by animal manure and rotating fodder crops, such as clover and alfalfa.

[. . .]

Isn’t it possible that crushing bugs and removing weeds by hands were neither very effective nor the most productive use of one’s time? That seeds purchased from commercial suppliers offered access to superior genetic material, were not mixed up with unwanted material and were readily available when needed? That “natural” manure has always been dirty, smelly, chock-full of pathogens and requires several months of composting? That the “slow release” of nutrients from green manures and organic compost could never be as adequately controlled to match crop demands with nutrient supply as is now possible with synthetic fertilizers? Further, that old mineral (including arsenic) and plant-based pesticides were less harmful to plant pests (and thereby more likely to promote insect resistance) and more problematic to human health than more recent offerings? That introducing nonnative insects, mammals and bacteria in a new ecosystem often had unintended, broader and longer-lasting negative consequences for nontargeted species? And that, unlike chemical pesticides that typically do not persist in an ecosystem once application has ceased, exotic insects who have successfully adapted to a new environment are practically impossible to eradicate and do not remain confined to one geographical location? In the end, why are modern agricultural producers willing to purchase costly synthetic inputs, hormonal growth promoters, antibiotics and genetically modified seeds when the methods agri-intellectuals prefer are either completely free (such as giving up on the use of these inputs and on equipment such as poultry housing) or seemingly much cheaper (such as feeding cattle entirely on pastureland and saving one’s seeds instead of relying on those marketed by specialized producers)?

Ontario’s ban on a large number of pesticides and herbicides for domestic use is re-acquainting many home owners with the joys of hand-weeding their lawns. It’s getting to the point that Ontario’s provincial flower might as well be the dandelion, as they’re everywhere. There’s a reason your ancestors couldn’t wait to get off the farm…

Justification for Thomas Szasz?

Filed under: Health, Liberty, Science — Tags: , — Nicholas @ 13:54

An interesting post at the Hit and Run blog by Jacob Sullum:

Last year, I was surprised to see Allen Frances, who headed the panel that produced the current edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, tell Gary Greenberg: “There is no definition of a mental disorder. It’s bullshit. I mean, you just can’t define it.” This week Frances surprised me again, declaring in his contribution to a Cato Unbound debate about psychiatric coercion that “mental disorders most certainly are not diseases.” Rather, he says, they are “constructs” that may justify treating people against their will as “a last resort.” Go here for my response. But start with Jeffrey Schaler’s opening essay, where he lays out the Szaszian position on mental illness, which Frances, the lead editor of psychiatry’s bible, says he basically agrees with, although “Schaler and Szasz go way too far in their total rejection of any need ever for involuntary treatment.”

US military faces recruiting nightmare

Filed under: Health, Military, USA — Tags: , , , , — Nicholas @ 09:17

Strategy Page outlines the most recent major problem the US military is facing: the bloat of potential recruits (not in numbers, but in individual mass). While the number of new recruits needed is declining, the pool of potential recruits to draw from has been declining even faster:

The problem is that Americans have, in the last two decades, become very fat and out-of-shape. There are 32 million male Americans of prime military age (17-24). But because of bad lifestyle choices, only 13 percent of them (4.2 million) are physically eligible for service. Each year, the armed forces have to recruit 150,000 new troops. The military is allowed to waive some physical or mental standards, and this means that only about 20 percent of those 32 million potential recruits qualify. Each year, recruiters have to convince about two percent of those eligible that they should join up. It’s a tough job, made worse by a generation that eats too much, exercises too little and doesn’t pay enough attention in school. You not only have to be physically fit enough to join, you also have to be smart enough and have no criminal record.

The enormous growth in computer entertainment, and subsequent massive reduction in exercise teenage boys get is the major reason for the body fat percentage crisis. As a result, one of the biggest problems American military recruiters have is unfit young Americans trying to enlist. Some 57 percent of potential recruits are not eligible because they do not score high enough on the aptitude test the military uses to see if people have enough education and mental skills to handle military life. Many of those who score too low do so because they did not do well at school. A lot of these folks have high IQs, but low motivation. Most of the remainder are not eligible for physical reasons. But get this; the most common physical disqualifier is being overweight. Nearly a third of the people of military age are considered obese. Many of these big folks are eager to join, and are told how much weight they have to lose before they can enlist. Few return light enough to sign up.

Computer gaming and other forms of indoor entertainment certainly bear some of the blame for the obesity problem, but other issues should also be included: helicopter parents who don’t dare let their kids go outside to play without full-time parental supervision, schools that have reduced or eliminated physical education for budget or liability reasons, and the huge increase in availability of low-priced, high-calorie fast foods.

Mongolian eco-toilet scheme quietly closed down

Filed under: Asia, Environment, Health, Technology — Tags: , , — Nicholas @ 14:38

From the Guardian:

The ecological toilets installed at Daxing were the design of Sweden’s Stockholm Environment Institute — about five million people use the model worldwide. In China, they are manufactured in the south-coast city of Chaozhou and cost about 700 or 800 yuan (US$100-125). Unlike normal toilets, they separate urine and excrement. In short, you aim your urine at the urine bowl and it is piped to an underground storage tank. And when you sit down, an excrement receptacle automatically pops out. You pull a lever to sprinkle some sawdust over your waste, and then when you stand up it flips over and everything is dumped down an excrement pipe to a tank in the basement. The tank is emptied two or three times monthly.

No water is used for flushing in either case — the cistern is full of sawdust, which residents collect from an office on-site. The toilets are designed to save water, prevent odours, and turn excrement into fertiliser. Fans blow air out of the pipes to the roof, and this is meant to ensure that smells do not enter the apartments.

Yan’s family just couldn’t get used to it. The toilet smelled bad from day one, they said: there was a stench of ammonia throughout the house, sometimes enough to make their eyes water as soon as they stepped into the bathroom. “I could hardly eat at home, and felt miserable on my way back after work,” said Yan. So the family usually ended up eating at Yan’s sister’s house. And their relatives didn’t want to visit.

The excrement bowls, which need to rotate, started to break. Every single house had to have the bowls repaired, and in 60% of households they needed to be replaced frequently. In 2007, Yan’s toilet was changed for one with a retractable tray, but the smells didn’t improve.

Matt Gurney: The LCBO and the “social responsibility” joke

Filed under: Business, Cancon, Government, Health — Tags: , , , , , — Nicholas @ 00:08

Following-up yesterday’s post on the call to break up the LCBO’s monopoly, Matt Gurney points out that the “social responsibility” claim is a farce:

It’s impossible for the LCBO to really pretend that its primary goal is to prevent Ontarians from drinking when it advertises heavily in print and broadcast media and has periodic sales and events to introduce consumers to new products. You’d think that would be enough to kill the social responsibility argument, but apparently not.

But there are plenty of other things that do. If Ontario believed that it had a social responsibility to directly control the sale of potentially harmful and addictive substances, why are cigarettes sold in every convenience store, milk mart and gas station in the province? Cigarettes kill an estimated 13,000 Ontarians every year. It’s completely inexplicable that this deadly substance can be sold by non-government monopolies while less lethal substances are tightly controlled under the banner of social responsibility. If the only way to ensure that alcohol is consumed in a socially responsible way is to have the province control its sale, why doesn’t that apply to tobacco? What about the two products is different in such a way that makes one OK for convenience stores and one not? This is the unanswered question that drives a stake through the heart of the social responsibility argument. Either the booze controls aren’t about social responsibility or the province is massively dropping the ball on the smokes. Which one is it, guys?

And it’s not like Ontario is somehow blind to the problem of smoking. During the tenure of Premier Dalton McGuinty, the province has cracked down on smoking in any number of ways, including but not limited to outlawing smoking in restaurants and bars (even those with specially ventilated smoking areas), making it illegal to smoke in a car containing a child (including, memorably, even if the child is a teenager who is also smoking), and forcing convenience store owners to cover up their cigarette displays, lest a child see a brightly coloured box and become a tobacco addict by default. All of these steps clearly demonstrate that Ontario is aware of, and concerned about, smoking. Yet I can still buy a pack at my local convenience store. Hmm.
