If Alcohol Were Discovered Today, Would it be Legal? - 0 views

  • This false distinction is a large part of the communication problem I encounter whenever I try to emphasise how harmful alcohol is. It has a separate language – you get “high” on drugs, but “drunk” on alcohol, drug addicts need a “fix” but alcoholics need a “drink.”
  • We are currently facing a public-health crisis of immense proportions. The increase in harms caused by alcohol over the last 50 years in the UK is comparable to the Gin Craze in the early 18th century, when the urban poor of London were consuming a pint of gin a day per head on average.
  • It’s certainly true that most societies throughout history have brewed some sort of alcoholic drink, and that this has been part of the human diet for so long that many of us are genetically adapted to consume alcohol.

  • So, drinking alcohol is “normal,” in a sense – people who possess the high-activity variant of the ALDH2 enzyme, come from a long line of people whose bodies adapted to consuming and breaking down alcohol. Indeed, until the 1850s weak beer was often “healthy”: it was the safest thing to drink, because most water was contaminated with viruses or bacteria. However, in the past most of what was drunk was mostly relatively low strength beer and wine, and its consumption was surrounded by custom and ritual to mitigate its social harms.
  • We’re at a similar point now in the UK: the access people have to cheap, high-strength alcohol is almost unprecedented, and binge drinking of the sort we see today is something our ancestors would rarely have been able to indulge in even if they’d wanted to.
  • The drug does have some positive psychological effects, and it can be calming for some people with anxiety disorders (see Case Study 1 below) although with heavy use the effects of withdrawal will start to make them even more anxious when they’re sober.
  • Physiologically, alcohol’s benefits have never been proven, but the idea that low levels of drinking are protective is a pervasive myth – and a very useful one for the industry.
  • However, this may be because this group has more healthy lifestyles, or because of the “sick teetotaller effect” – where many people give up alcohol because they are ill (perhaps from some other disease); their worse health outcomes may have nothing to do with whether or not they drink, but do make the health statistics of non-drinkers appear worse.
  • There is no such thing as a safe level of alcohol consumption. Alcohol is a toxin that kill cells and organisms, which is why we use it to preserve food and sterilize needles.
  • Alcohol is a depressant (similar to GHB, and benzodiazepines like Valium) which, if taken at high enough doses, will produce amnesia, sedation and eventually death.
  • Alcohol also indirectly stimulates the noradrenaline circuit, producing some stimulating effects. This is what creates the noisy energy we associate with drunkenness, even though the drug is a depressant.
  • Some interesting recent research showed that alcohol interferes with our ability to recognize emotions in facial expressions, which may be part of the reason drunk people are so quick to take offense and start fights.
  • Millions of people, not a tiny minority, suffer harm from their own alcohol consumption, or cause harm to others.
  • These are all perfectly valid choices, yet non-drinkers are often heavily pressured to consume alcohol in order to fit in with others. This message is constantly reinforced in the press, on TV, and in alcohol advertising.
  • Far from being safe, there is no other drug which is so damaging to so many different organ systems in the body. Figure 6.2 illustrates how alcohol can harm almost every part of the body through its toxicity alone.
  • But there is a fundamental conflict of interest: however much the industry wants to pretend otherwise, you can’t reduce harm without reducing the amount people drink, whereas companies looking to maximize profits need to sell as much alcohol as possible.

    "A terrifying new "legal high" has hit our streets. Methyl-carbonol, known by the street name "wiz," is a clear liquid that causes cancers, liver problems, and brain disease, and is more toxic than ecstasy and cocaine. Addiction can occur after just one drink, and addicts will go to any lengths to get their next fix - even letting their kids go hungry or beating up their partners to obtain money. Casual users can go into blind rages when they're high, and police have reported a huge increase in crime where the drug is being used. Worst of all, drinks companies are adding "wiz" to fizzy drinks and advertising them to kids like they're plain Coca-Cola. Two or three teenagers die from it every week overdosing on a binge, and another 10 from having accidents caused by reckless driving. "Wiz" is a public menace - when will the Home Secretary think of the children and make this dangerous substance Class A?"

If the Earth Stood Still - What Would Happen if the Earth Stopped Spinning? - 0 views

  • Typically, we do not pay much attention to the delineation of the sea because it seems so obvious and constant that we do not realize it is a foundation of geography and the basis for our perception of the physical world.
  • Why is the sea level where we currently observe it? What controls the sea level? How stable are the forces that determine the sea level? This article does not refer to the climate change and the potential increase of the water level in the global ocean but rather to the geometry of the globe and the powerful geophysical energies that determine where oceans lie.
  • Sea level is—and has always been—in equilibrium with the planet's gravity, which pulls the water toward the earth's center of mass, and the outward centrifugal force, which results from the earth's rotation. After a few billion years of spinning, the earth has taken on the shape of an ellipsoid (which can be thought of as a flattened sphere). Consequently, the distance to the earth's center of mass is the longest around the equator and shortest beyond the polar circles.
  • ...3 more annotations...
  • What would happen if the earth's rotation slowed down and finally stopped spinning over a period of a few decades? ArcGIS lets us model the effects of this scenario, performing calculations and estimations and creating a series of maps showing the effects the absence of centrifugal force would have on sea level.
  • The lack of the centrifugal effect would result in the gravity of the earth being the only significant force controlling the extent of the oceans. Prominent celestial bodies such as the moon and sun would also play a role, but because of their distance from the earth, their impact on the extent of global oceans would be negligible.
  • If the earth's gravity alone was responsible for creating a new geography, the huge bulge of oceanic water—which is now about 8 km high at the equator—would migrate to where a stationary earth's gravity would be the strongest.

    "The following is not a futuristic scenario. It is not science fiction. It is a demonstration of the capabilities of GIS to model the results of an extremely unlikely, yet intellectually fascinating query: What would happen if the earth stopped spinning? ArcGIS was used to perform complex raster analysis and volumetric computations and generate maps that visualize these results."

Why Bill Clinton's Speeches Succeed - 0 views

  • Different people have different natural modes for their speech, and not many people can pull it off just the way Clinton does. But Clinton reminds us of the value (and rarity) of this tone in politics -- and the next time you listen to a sports-talk channel, think how much better our political discussion would be if participants assumed as much sophistication about argument as ESPN and radio-talk hosts do.

    "Because he treats listeners as if they are smart. That is the significance of "They want us to think" and "The strongest argument is" and "The arithmetic says one of three things must happen" and even "Now listen to me here, this is important." He is showing that he understands the many layers of logic and evidence and positioning and emotion that go into political discussion -- and, more important, he takes for granted that listeners can too." Thanks, Erik.

Arsenic in Rice: of Baby and Bath Water - 0 views

health arsenic

shared by anonymous on 01 Oct 12 - Cached
  • Arsenic is an element present in the earth's crust. There would likely be some of it in ground water even without the human activities that traumatize that crust in a variety of ways, but not enough to threaten health. Our various activities that have moved both rocks and water, from mining to drilling wells into aquifers, have resulted in significant mobilization of arsenic from rock into ground water.
  • Arsenic comes in two forms, organic and inorganic.
  • Organic arsenic, which is present in foods in very small amounts, is probably non-toxic, and may even be an essential trace element.
  • ...14 more annotations...
  • Inorganic arsenic is certainly a toxin, as was made famous in the movie, Arsenic and Old Lace. It is the primary variety released from rocks into water, and the main concern for human health.
  • Attention to arsenic in the environment by the Environmental Protection Agency, and in our food by the FDA, can only be a good thing, advancing food safety. Eating a variety of whole grains, for those without reasons to avoid them such as gluten sensitivity, is good for health in general—and may also reduce arsenic intake.
  • But inevitably, when a peril in our food or medicine cabinet or environment is pointed out to us, it invites the hyperbole of concentrated media attention, an inclination to invoke conspiracy theories, and at least some temptation to panic. When we do give in to panic, we tend to jettison the baby along with the bath water, resulting in net harm.
  • 1. Don't make perfect the enemy of good.
  • since we can't have perfectly pure food, the operative question in the real world is: Which of the available choices are best for health?
  • The presence of a contaminant in food does not reliably indicate that eating the food is harmful.
  • Similarly, there is more arsenic in brown rice than white, but the health benefits of eating a whole grain may outweigh that.
  • 2. Don't exaggerate a risk just because you don't control it.
  • We have known for decades that the four leading causes of chronic disease and premature death in industrialized countries are smoking, poor dietary pattern, lack of physical activity, and obesity. Yet these four are routinely ignored or neglected by people who get very worked up over the latest chemical threat in our food or environment.
  • We should not ignore big risks just because they are under our control, nor exaggerate much smaller ones simply because they are not.
  • 3. New in the news is not new in the world.
  • The tendency when a chemical threat is highlighted in the news is to think the threat itself is new, and the consequences are unknown, and in the future. But if arsenic in rice or other foods does actually contribute to cancer risk, it has been doing so for years.
  • the notion that there is a spike in cancer or other disease rates looming around the next bend is misguided; we are already around that bend, and any harms of arsenic are already part of the epidemiologic landscape we know.
  • Perfectly pure food is, alas, not available on this planet. So those of us living here should focus on net health effects rather than the media hype du jour, and do the best we can with the food supply we've got.

    "Predictably, there was widespread media attention to a recent release by Consumer Reports highlighting contamination of rice by arsenic. In customary "consumer watchdog" fashion, Consumer Reports presented a long list of popular consumer products, from cooking rice, to rice cakes, to breakfast cereal, and most worrisome, baby food, with arsenic levels in each. The story was covered extensively by the major network news programs."

Steve Martin's Advice for Building a Career You Love - 0 views

  • In the last five minutes of the interview, Rose asks Martin his advice for aspiring performers. "Nobody ever takes note of [my advice], because it's not the answer they wanted to hear," Martin said. "What they want to hear is ‘Here's how you get an agent, here's how you write a script,' . . . but I always say, ‘Be so good they can't ignore you.' "
  • It took Martin, by his own estimation, ten years for his new act to cohere, but when it did, he became a monster success. It's clear in his telling that there was no real shortcut to his eventual fame, and the compelling life it generated. "[Eventually] you are so experienced [that] there's a confidence that comes out," Martin explained. "I think it's something the audience smells."
  • If you're not focusing on becoming so good they can't ignore you, you're going to be left behind. This clarity is refreshing. It tells you to stop worrying about what your job offers you, and instead worry about what you're offering the world.
  • ...5 more annotations...
  • As I'll explain below, regardless of how you feel about your job right now, adopting the craftsman mindset can be the foundation on which you build a compelling career.
  • Research shows that the traits that lead people to love their work are general, and can be found in many different career paths. They include things like autonomy, a sense of impact and mastery, creativity, and respect and recognition for your abilities. Once you recognize that these traits have little to do with following a pre-existing passion, and can be cultivated in many different fields, you can safely abandon the myth that there's a single right job waiting out there for you.
  • Basic economic theory tells us that if you want something that's both rare and valuable, you need something rare and valuable to offer in return—this is Supply and Demand 101.
  • They start by painstakingly developing rare and valuable skills—which we can call career capital. They then leverage this capital to gain rare and valuable traits in their career. These traits lead to a feeling of passion about their working life.
  • The reality I'm proposing is less glamorous. It argues that passion takes time and hard work—harder work than most people naturally invest in their jobs. It's also less certain in the sense that you cannot predict in advance the details of the compelling career you're cultivating. But it compensates with clarity.

    "To simplify things, I'll use the "passion hypothesis" to refer to the popular belief that the way to end up loving your career is to first figure out what you're passionate about, and then pursue it (a strategy often summarized with the pithy phrase, "follow your passion.") The more I studied this hypothesis, the more I noticed its danger. This idea convinces people that there's a magic "right" job waiting for them, and that if they find it, they'll immediately recognize that this is the work they were meant to do. The problem, of course, is when they fail to find this certainty, bad things follow, such as chronic job-hopping and crippling self-doubt."
