Heavy Metal and Clever Teenagers

By Dr. Richard G. Petty, M.D. | April 30th, 2007

You humble reporter loves music: anything from Mozart to Metallica.

She Who Must Be Obeyed is one of many people who has wondered at my enthusiasm for bands like Iron Maiden and Metallica. Was I, perhaps, dropped on my head as a child?

I was gratified to see a report of a study that was presented at a recent meeting of the British Psychological Society in York, indicating that intelligent teenagers often listen to heavy metal music to cope with the pressures associated with being talented.

Though sadly your humble reporter is no longer a teenager, the seeds of his enthusiasm for this kind of music were sown many years ago.

Stuart Cadwallader and Professor Jim Campbell of The National Academy for Gifted and Talented Youth at the University of Warwick looked at 1,057 students
aged between 11 and 18 years old who completed a survey asking them
about family, school attitudes, leisure time pursuits and media
preferences. They also asked them to rank favored genres of music.

They found that rock was the most popular form of music, closely followed by pop.

Researchers found that, far from being a sign of delinquency and poor academic ability, many adolescent “metalheads” are extremely bright and often use the music to help them deal with the stresses and strains of being gifted social outsiders.

Stuart Cadwallader has this to say,

“There is a perception of gifted and talented students as being into classical music and spending a lot of time reading. I think that is an inaccurate stereotype. There is literature that links heavy metal to poor academic performance and delinquency but we found a group that contradicts that… Participants said they appreciated the complex and sometimes political themes of heavy metal music more than perhaps the average pop song. It has a tendency to worry adults a bit but I think it is just a cathartic thing. It does not indicate problems.”

There was something about the metal heads having lower self-esteem and more difficulties in family relationships, but your humble reporter isn’t too sure about that bit….

But here’s the important thing: all things in moderation. A lot of loud heavy metal music may not be good for your health. The data is anecdotal, and comes from sources like the Emoto experiments with water crystals, that have still not been replicated.

But as a rule of thumb, some occasional loud music probably never hurt anyone unless they turned up the volume too high. Listening to it all day long could be damaging to your health.

A Pill for Every Ill?

By Dr. Richard G. Petty, M.D. | April 30th, 2007

Many of us have been becoming more and more worried by the idea that if we don’t like something, then we should take a pill, rather than trying to get to grips with the causes.

Can’t sleep? Take this pill. {Ahem, but why not try sleep hygiene first?)

Shy? No, you’re not allowed to be shy, you have social phobia, take this medicine.

Don’t like the size of your tummy? Don’t exercise; we have just the pill for you!

Not only does this approach undermine our responsibility and autonomy, it also minimizes the suffering of people with real clinical problems. When every headache gets labeled a “migraine” and every cold gets turned into “’flu,” it is easy to lose patience, empathy and understanding for people who are really suffering with the genuine article.

Here is a fine example of an announcement that has doubtless caught the attention of headline writers around the world. Researchers from the Medical Research Council’s Human Reproduction Unit in Edinburgh in Scotland are reported to be working on a pill that would simultaneously boost a woman’s libido while at the same time reducing her appetite for food.

So what is this all about? Professor Robert Millar leads the Edinburgh team that has been looking at the properties type 2 gonadotropin-releasing hormone (GnRH), one of the hormones responsible for the release of sex hormones.

When it was given to monkeys, they displayed mating behavior such as tongue-flicking and eyebrow-raising to the males. When it was given female musk shrews, they displayed their feelings via “rump presentation and tail wagging.” These are two interesting visual images.

The thing is this. The tongue-flicking, eyebrow-raising tail wagers also ate around a third less food than they normally would. So now the search is on to find a pharmaceutical company that would like to make some kind of GnRH pill that would, presumably, produce libidinous skinny women.

Not only is this a frightful type of reductionism, but it raises all kinds of ethical issues.

The researchers in Edinburgh have been turning out a substantial body of very respectable data over the years, and this story looks very much like something that has been embellished.

Few people believe that eating or human sexuality are reducible to single chemicals in the brain. Low libido is a common problem, but it is usually a sign of stress, fatigue or relationship problems, rather than a chemical imbalance in the brain. And what, when and how we eat is an extraordinarily complex issue that is as much psychological and social as it is chemical. Stimulating the libido of someone in a lousy relationship is unlikely to lead to peace and harmony.

The whole concept also returns to the question of “what is normal?” when it comes to food, size or sex.

Mastering Chess: Genes or Environment?

By Dr. Richard G. Petty, M.D. | April 29th, 2007

It is always interesting to look at people who have excelled at something to see what we can learn.

I recently talked about the new research indiating that there are some genes that have some impact on intelligence.

There is an interesting article in today’s New York Times, entited, “Nature? Nurture? Never Mind. Here’s a Sister Act to Watch,” by Dylan Loeb McClain. He has this to say:

“Siblings who are elite chess players are rare. The best known are probably the Polgar sisters of Hungary. Susan, the eldest, is a grandmaster and former women’s world champion. Sofia is an international master. And Judit, the youngest, is the best woman player in history.

Other notable chess-playing siblings have included the Byrne brothers, Robert, a grandmaster and the longtime columnist for The New York Times, and Donald, an international master who died at 45; and Gregory Shahade, an international master, and Jennifer Shahade, a two-time United States women’s champion, who were taught chess by their father, Michael, a master.

Why so few elite sibling players? Is it simply because it is highly unlikely for a single family to produce multiple elite players? Or do most siblings have different interests?

The questions go to the heart of a familiar debate: Is chess talent innate or nurtured?

In his popular book “The Immortal Game,” David Shenk said great chess players were made, not born, writing, “Cognitive chess research punctured the longstanding myth of the chess prodigy, the born genius.”

The best players, Shenk wrote, are the product of intensive study and training. He said the Polgar sisters, who were raised by their father, Laszlo, from an early age to be chess players, were a prime example.

Shenk recounts an episode years ago in which Susan was studying with an international master and they had a problem they could not solve. They woke up young Judit, who, half-asleep, found the solution immediately and went back to bed.

Aren’t the varying levels of talent among the Polgar sisters, who all presumably had the same training, evidence of innate differences? Possibly.

A pair of sisters who have been making a big splash lately do not seem to be separated by ability, at least so far. Nadezhda and Tatiana Kosintseva of Russia are ranked No. 14 and No. 24 in the world among women. But at the European championships, which concluded April 15, Tatiana ran away from a large field, finishing two points ahead of her sister.”


There is undobtedly some set of genes that increase the chance that someone will be good at some game or other, whether it is chess or golf. But there is also the family, school or club that can help someone to realize their true potential.

But even if the genes aren’t all there, you can still become highly competent if you have learned how to learn and if you have learned the arts of patience, perseverance and persistence.

Biology is not destiny!

Honey Bees, Blue Tits and Canaries

By Dr. Richard G. Petty, M.D. | April 29th, 2007

“If the bee disappeared off the surface of the globe, then man would only have four years of life left.”
–Albert Einstein (German-born American Physicist and, in 1921, Winner of the Nobel Prize in Physics, 1879-1955)

Anyone interested in Integrated Medicine should also be interested in trends that may have a major impact on our health and our potential to grow.

Over the last year the sparrow population of England has been declining, and now there is something new. In recent weeks there have been reports from bird watchers in Southern England that some species of birds have suddenly started become obese. The birds most affected seem to be blue tits. There is no suggestion about why it is happening, or what they are eating. Or whether something else in the environment is changing and causing the problem.

Second, British Government inspectors are investigating reports of unusually high numbers of honeybee deaths. Beekeepers all over Southern England are reporting that their hives have been decimated. This is a serious matter. Not just to the bees, but because bees pollinate fruit trees and other crops, the consequences for British farmers of a collapse in honey bee numbers could be devastating. The total contribution of bees to the British economy has been estimated at somewhere around 2 billion dollars.

No one yet understands the cause of these widespread honey bee colony deaths, and it is not just in the England: unexplained, severe colony losses with bees failing to return from their searches for pollen and nectar in Poland, Greece, Italy, Spain and Portugal.

But here in the United States the situation is even worse: Beekeepers in 25 US states have lost 50 to 90 per cent of their colonies to a mystery condition being called Colony Collapse Disorder (CCD) - in which bees suddenly abandon their hives and disappear to die. It is having a major effect on the mobile apiaries (Bee farms) that are transported across the US to
pollinate large-scale crops, such as oranges in Florida or almonds in
California. Some have lost up to 90 per cent of their bees.

The cause of CCD is unknown, but some of the suspects include pesticides, malnutrition, antibiotics, mites and increased solar radiation due to ozone thinning. There has also been a theory that it might have something to do with all those towers that support the cell phone network, or the introduction of genetically modified crops.

In the 1990s, honeybee populations were badly affected by the varroa mite - a parasite that makes colonies more vulnerable to viruses. Some experts believe the recent deaths could be caused by the parasite becoming resistant to drugs used against it.

Like most things in nature, animal populations go through regular cycles: there is a sophisticated mathematics that can be used to describe fluctuations in populations. But when we see several odd things at once, that don’t fit the mathematical models, it is time to ask the question whether the obese blue tits and the disappearance of sparrows and bees are a harbinger of further changes in our environment.

Are the bees and blue tits the “Canaries in the Coal Mine”?

Attention-Deficit/Hyperactivity Disorder: Diagnosis and Complications

By Dr. Richard G. Petty, M.D. | April 29th, 2007

I have had a great many requests to talk more about attention-deficit/hyperactivity disorder (ADHD): what it is, and what it is not; when is it a problem and when is it just “normal” childhood or adolescent behavior? And what evidence is there for non-pharmacological approaches?

Although there is a lot of information about ADHD available in books and on line, some is better than others, and some is misleading. I have recently had the privilege of giving a series of lectures on each of these topics, and many people have thought that I had a different take on the issue, so I an going to summarize some of the lectures here.

First I would like to direct you to a short article on the diagnosis on ADHD. The most important point is that we have to tell the difference between kids being kids and a problem that needs treatment.

Second is an article that talks about some of the problems that may follow if someone has ADHD and it is not diagnosed or treated.

Over the next two days I am going to follow up with articles that I have written on "Non-pharmacological and Lifestyle Approaches to Attention-Deficit/Hyperactivity Disorder":
Diet, nutrition, allergies and sensitivities
Herbs and supplements
Movement, exercise, sleep and environmental design
Massage, qigong, tapping therapies and acupuncture
Mind-body approaches to treating ADHD
Homeopathy and flower essences in ADHD
Using Integrated Medicine in ADHD

“Thoughts of themselves have no substance; let them arise and pass away unheeded. Thoughts will not take form of themselves, unless they are grasped by the attention; if they are ignored, there will be no appearing and no disappearing.”
–Bhikshu Ashvaghosha (Indian Playwright and Master of Buddhist Philosophy, c. A.D. 1st Century)


“The true art of memory is the art of attention.”

–Samuel Johnson (English Biographer and Essayist, 1709-1784)

“Attention makes the genius; all learning, fancy, and science depend upon it. Newton traced back his discoveries to its unwearied employment. It builds bridges, opens new worlds, and heals diseases; without it taste is useless, and the beauties of literature are unobserved.”
–Robert Aris Willmott (English Author, 1809-1863)
