Ban of TV Rates High with the Stars

Children in North America are undoing the television revolution.

A small but significant trend among middle-class parents to enforce "NO TV" days is paying off in higher levels of fitness, schoolwork and even happiness, according to new research. 

The growing anti-television movement received a boost recently when Tom Cruise and Steven Spielberg, who both made their fortunes in film, said they were curbing their children's viewing in favour of traditional entertainments such as books, sports, and even conversation.

At a time when the average child watches 25 hours of TV a week, more parents are banishing the box for one night a week.

Cruise, 40, who, with Nicole Kidman in the mid-1990s, adopted two children said he imposed strict limits.  "I don't really like my kids to watch that much television.  They are allowed about 3.5 hours a week, but only if they are doing well in school.  We're focused on reading, a lot of reading," he said.

Many children have swapped one screen for another, devoting more hours to computer games, but Cruise believes he has headed off that threat.  "I really don't like to leave them alone on computers - I am not convinced it is healthy for them," he added.

Spielberg said his Los Angeles home was often filled with children - he and Kate Capshaw have five - but the rule remains the same for all.  "One hour of TV a day, but only if they have met the conditions," said the director.  

"They have to do their homework, do their chores, finish dinner and get into their cozy clothes.  After they take their bath and after they are in their cozy clothes, they get to watch TV for an hour.  

"I do not let them watch the news because it is much more uncensored than it was when I was growing up and things are so frightening right now that I like the news to come from me.  That way I can reassure them that they are safe," Spielberg said.

The kings of Hollywood are not alone in expressing their reservations about using television as an "electronic babysitter".  Madonna has pledged "minimal TV" for her children, while Australian actor Naomi Watts, 34, best know for her lead role in the David Lynch film, Mulholland Drive, said:  "I will not allow them to watch anything but World Cup soccer on it.  Once every four years should be enough."

Lobbyists, ranging from religious groups to liberals opposed to the impact of advertising on young minds, are uniting against television.  Earlier this year, a Washington based organization called TV-Turnoff persuaded 6.5 million people to switch off their sets for an entire week. 

"Do not be fooled, for many families it was a tough gig," said one campaigner.  Some reported "withdrawal behaviours" such as disbelief, tantrums and cheating.  

The winners in the trend to abandon television for a night are toy manufacturers.  They boast of increased sales of traditional games such as Scrabble and Monopoly, ironically promoted through television advertising campaigns urging families to "play together" once a week.

Computer trends are changing too, with sales of violent "shoot'em up" games favoured by adolescent boys declining.

A recent report from the Kaiser Family Foundation said children who cut down their viewing by a few hours a week showed remarkable gains at school and in social relations.

A foundation spokesman said: "The American constitution guarantees the right to pursue happiness.  This is the best recipe for happiness we have seen without medication for years."

The Science of Anxiety

It's 4 a.m., and you're wide-awake — palms sweaty, heart racing. You're worried about your kids. Your aging parents. Your pension. Your health. Your sex life. Breathing evenly beside you, your spouse is oblivious. Doesn't he — or she — see the dangers that lurk in every shadow? He must not. Otherwise, how could he, with all that's going on in the world, have talked so calmly at dinner last night about flying to Florida for a vacation?

How is it that two people facing the same circumstances can react so differently? Why are some folks buffeted by the vicissitudes of life while others glide through them with grace and calm? Are some of us just born more nervous than others? And if you're one of them, is there anything you can do about it?  

The key to these questions is the emotional response we call anxiety. Unlike hunger or thirst, which build and dissipate in the immediate present, anxiety is the sort of feeling that sneaks up on you from the day after tomorrow. It's supposed to keep you from feeling too safe. Without it, few of us would survive.

All animals, especially the small, scurrying kind, appear to feel anxiety. Humans have felt it since the days they shared the planet with saber-toothed tigers. (Notice which species is still around to tell the tale.) But we live in a particularly anxious age. The initial shock of Sept. 11 has worn off, and the fear has lifted, but millions of Americans continue to share a kind of generalized mass anxiety. A recent TIME/CNN poll found that eight months after the event, nearly two-thirds of Americans think about the terror attacks at least several times a week. And it doesn't take much for all the old fears to come rushing back. What was surprising about the recent drumbeat of terror warnings was how quickly it triggered the anxiety so many of us thought we had put behind us.

This is one of the mysteries of anxiety. While it is a normal response to physical danger — and can be a useful tool for focusing the mind when there's a deadline looming — anxiety becomes a problem when it persists too long beyond the immediate threat. Sometimes there's an obvious cause, as with the shell-shocked soldiers of World War I or the terror-scarred civilians of the World Trade Center collapse. Other times, we don't know why we can't stop worrying.

There is certainly a lot of anxiety going around. Anxiety disorder — which is what health experts call any anxiety that persists to the point that it interferes with one's life — is the most common mental illness in the U.S. In its various forms, ranging from very specific phobias to generalized anxiety disorder, it afflicts 19 million Americans (see "Are You Too Anxious?").

And yet, according to a survey published last January by researchers from UCLA, less than 25% of Americans with anxiety disorders receive any kind of treatment for their condition. "If mental health is the stepchild of the health-care system," says Jerilyn Ross, president of the Anxiety Disorders Association of America, "then anxiety is the stepchild of the stepchild."

Sigmund Freud was fascinated with anxiety and recognized early on that there is more than one kind. He identified two major forms of anxiety: one more biological in nature and the other more dependent on psychological factors. Unfortunately, his followers were so obsessed with his ideas about sex drives and unresolved conflicts that studies of the physical basis of anxiety languished.

In recent years, however, researchers have made significant progress in nailing down the underlying science of anxiety. In just the past decade, they have come to appreciate that whatever the factors that trigger anxiety, it grows out of a response that is hardwired in our brains. They have learned, among other things:
        • There is a genetic component to anxiety; some people seem to be born worriers.
        • Brain scans can reveal differences in the way patients who suffer from anxiety disorders respond to danger signals.
        • Due to a shortcut in our brain's information-processing system, we can respond to threats before we become aware of them.
        • The root of an anxiety disorder may not be the threat that triggers it but a breakdown in the mechanism that keeps the anxiety response from careering out of control.

Before we delve into the latest research, let's define a few terms. Though we all have our own intuitive sense of what the words stress and fear mean, scientists use these words in very specific ways. For them, stress is an external stimulus that signals danger, often by causing pain. Fear is the short-term response such stresses produce in men, women or lab rats. Anxiety has a lot of the same symptoms as fear, but it's a feeling that lingers long after the stress has lifted and the threat has passed.

In general, science has a hard time pinning down emotions because they are by nature so slippery and subjective. You can't ask a rat if it's anxious or depressed. Even most people are as clueless about why they have certain feelings as they are about how their lungs work. But fear is the one aspect of anxiety that's easy to recognize. Rats freeze in place. Humans break out in a cold sweat. Heartbeats race, and blood pressure rises. That gives scientists something they can control and measure. "You can bring on a sensory stimulus that makes an animal — or human — fearful and study its effects," says Dr. Wayne Drevets of the National Institute of Mental Health (nimh). "Then you can take the stimulus away and see how the animal calms down."

Indeed, a lot of what researchers have learned about the biology of anxiety comes from scaring rats and then cutting them open. Just as the Russian physiologist Ivan Pavlov showed 100 years ago that you could condition a dog to salivate at the sound of a bell, scientists today have taught rats to fear all kinds of things — from buzzers to lights — by giving them electrical shocks when they hear the buzzer or see the light. The animals quickly learn to fear the stimulus even in the absence of a shock. Then researchers destroy small portions of the rats' brains to see what effect that has on their reactions (an experiment that would be impossible to conduct in humans). By painstakingly matching the damaged areas with changes in behavior, scientists have, bit by bit, created a road map of fear as it travels through the rat's brain.

The journey begins when a rat (we'll get to humans later) feels the stress, in this case an electric shock. The rat's senses immediately send a message to the central portion of its brain, where the stimulus activates two neural pathways. One of these pathways is a relatively long, circuitous route through the cortex, where the brain does its most elaborate and accurate processing of information. The other route is a kind of emergency shortcut that quickly reaches an almond-shaped cluster of cells called the amygdala.

What's special about the amygdala is that it can quickly activate just about every system in the body to fight like the devil or run like crazy. It's not designed to be accurate, just fast. If you have ever gone hiking and been startled by a snake that turned out to be a stick, you can thank your amygdala. Joseph LeDoux, a neuroscientist at New York University, calls it "the hub in a wheel of fear."

But while the amygdala is busy telling the body what to do, it also fires up a nearby curved cluster of neurons called the hippocampus. (A 16th century anatomist named it after the Greek word for seahorse.) The job of the hippocampus is to help the brain learn and form new memories. And not just any memories. The hippocampus allows a rat to remember where it was when it got shocked and what was going on around it at the time. Such contextual learning helps the poor rodent avoid dangerous places in the future. It probably also helps it recognize what situations are likely to be relatively safe.

By this point, the other half of the stress signal has reached the cortex, which confirms that there's a danger present and figures out that it's causing pain. Once the shock has warn off, a part of the brain called the prefrontal cortex sends out an all-clear message and lets the amygdala know that it's O.K. to stand down. At least it's supposed to. It seems that it's harder to turn off a stress response than to turn it on. This makes sense, in terms of survival. After all, it's better to panic unnecessarily than to be too relaxed in the face of life-threatening danger.

Discovering this basic neural circuitry turned out to be a key breakthrough in understanding anxiety. It showed that the anxiety response isn't necessarily caused by an external threat; rather, it may be traced to a breakdown in the mechanism that signals the brain to stop responding. Just as a car can go out of control due to either a stuck accelerator or failed brakes, it's not always clear which part of the brain is at fault. It may turn out that some anxiety disorders are caused by an overactive amygdala (the accelerator) while others are caused by an underactive prefrontal cortex (call it the brake).

It may also be that an entirely different part of the brain holds the key to understanding anxiety. Michael Davis, a behavioral neuroscientist at Emory University in Atlanta, has spent six years studying a pea-size knot of neurons located near the amygdala with an impossible name: the bed nucleus of the stria terminalis, or BNST. Rats whose BNST has been injected with stress hormones are much jumpier than those that have got a shot in their amygdala. Could the BNST be at the root of all anxiety disorders? The clues are intriguing, but as scientists are so fond of saying, more research is needed.

Of course, what you would really like to know is whether any of the work done in rats applies to humans. Clearly researchers can't go around performing brain surgery on the amygdalas of living patients to see if it affects their anxiety levels. But the fascinating case of a woman known only by her research number, SM046, suggests that when it comes to fear, rodents and hominids really aren't so different.

Owing to an unusual brain disorder, SM046 has a defective amygdala. As a result, her behavior is abnormal in a very particular way. When scientists at the University of Iowa show SM046 pictures of a series of faces, she has no trouble picking out those that are happy, sad or angry. But if the face is displaying fear, she cannot recognize the feeling. She identifies it as a face expressing some intense emotion, but that is all. Her unusual condition strongly suggests that even in Homo sapiens, fear takes hold in the amygdala.

But studying brain-damaged patients can teach scientists only so much. They would also like to know how anxiety works in normal, intact brains. For this, brain scans have proved invaluable.

For years, doctors have used cat scans and MRIs to help them diagnose strokes, brain tumors and other neurological conditions. But as the technology has become more sophisticated, researchers have started to employ it to tease out some of the subtle changes associated with mental illness. "We're not yet able to use these scans in a diagnostic way," says Dr. David Silbersweig of the Weill Cornell Medical College in New York City. "But we're getting pretty specific about the areas of the brain that are implicated in a number of psychiatric disorders."

One type of brain scan helps identify structures that are the wrong size or shape. Two years ago, researchers at the University of Pittsburgh showed that the amygdalas of a group of overanxious young children were, on average, much larger than those of their unaffected peers. Perhaps they just had more fear circuits to contend with? Neuroscientists are tempted to say yes, but they admit the conclusion is pretty speculative. Another group of researchers found that patients with post-traumatic stress disorder had a smaller hippocampus than normal. Perhaps their stressful experiences had somehow interfered with the hippocampus' ability to make new memories and, just as important, forget the old ones? Again, no one knows for sure.

Another type of brain scan tells scientists which brain cells are using the most oxygen or soaking up the most nutrients. The idea, explains Dr. Scott Rauch of Massachusetts General Hospital, is that any area that seems more active than usual while someone is anxious may play an important role in making the person that way. Rauch's team has spent the past eight years scanning groups of combat veterans, some with post-traumatic stress disorder and some without, to see which areas of the brain light up when they hear tapes recounting their most troubling memories. So far, the signals in the amygdala appear to be more active in those with ptsd than in those without. In addition, signals to the prefrontal cortex of PTSD subjects seem to be weaker than in those without the disorder. Perhaps this explains why the patients still feel threatened even when they are perfectly safe.

The next step, Rauch says, is to scan groups of people who are likely to be thrust into dangerous situations — fire fighters, say, or police officers. Then it may be possible to determine if any changes in their brains are the result of traumatic situations or if the changes predate them. Either is plausible. The stress of surviving a building collapse, for example, could turn a normal amygdala into an overactive one. Or an already overactive amygdala may overwhelm the brain in the wake of a disaster.

Eventually, researchers would like to learn what role our genes, as opposed to our environment, play in the development of anxiety. "It has been known for some time that these disorders run in families," says Kenneth Kendler, a psychiatric geneticist at Virginia Commonwealth University in Richmond, Va. "So the next logical question is the nature-nurture issue." In other words, are anxious people born that way, or do they become anxious as a result of their life experiences?

Kendler and his colleagues approached the question by studying groups of identical twins, who share virtually all their genes, and fraternal twins, who, like any other siblings, share only some of them. What Kendler's group found was that both identical twins were somewhat more likely than both fraternal twins to suffer from generalized anxiety disorder, phobias or panic attacks. (The researchers have not yet studied twins with post- traumatic stress disorder or obsessive- compulsive disorder.)

The correlation isn't 100%, however. "Most of the heritability is in the range of 30% to 40%," Kendler says. That's a fairly moderate genetic impact, he notes, akin to the chances that you will have the same cholesterol count as your parents. "Your genes set your general vulnerability," he concludes. "You can be a low-vulnerable, intermediate-vulnerable or a high-vulnerable person." But your upbringing and your experiences still have a major role to play. Someone with a low genetic vulnerability, for example, could easily develop a fear of flying after surviving a horrific plane crash.

There is plenty to learn about how anxiety and fear shape the brain. One of the biggest mysteries is the relationship between anxiety and depression. Researchers know that adults who suffer from depression were often very anxious as children. (It's also true that many kids outgrow their anxiety disorders to become perfectly well-adjusted adults.) Is that just a coincidence, as many believe, or does anxiety somehow prime the brain to become depressed later in life? Brain scans show that the amygdala is very active in depressed patients, even when they are sleeping. Studies of twins suggest that many of the same genes could be involved. "There's a lot of overlap," says Dr. Dennis Charney, chief of the research program for mood and anxiety disorders at the NIMH. "Anxiety and depression have a similar underlying biology, and the genetics may be such that anxiety surfaces early in life and depression later on." Still, no one can say for sure.

Certainly antidepressants, like the serotonin reuptake inhibitors (Prozac and others) have proved very helpful in treating anxiety; some doctors think they are even more effective against anxiety than they are against depression. Although no one knows exactly why these antidepressants work, one important clue is that their effects don't show up until after a few weeks of treatment. The pathways for toning down anxiety are apparently much more resistant than those for ratcheting it up.

It's a mistake, however, to think that pills alone can soothe your neurochemistry. Remember the cortex? That's where you would expect psychotherapy to work, increasing the repertoire of calming messages that can be passed along to the amygdala. Certain desensitization techniques can also help the brain learn, through the hippocampus, to be less reactive. Of course, you have to do it right. Reliving a trauma too soon after it happened could also make the memory harder to erase.

There are no guidebooks to tell you when it's safe to venture out again. In many ways, the whole country last September was made part of an unwitting experiment in mass anxiety. Our brains are even now in the process of rewiring themselves. How successfully we navigate this delicate transition will depend a lot on our genes, our environment and any future attacks.

Are You Too Anxious?

Everybody feels a bit of anxiety from time to time, but a clinical anxiety disorder is a different matter. If you suspect you may be suffering from one, you should consult a professional for a diagnosis. The psychological diagnostic manual lists 12 anxiety conditions. Here are the signs of five of the most common ones:

Blind Date

"How was your blind date?" a college student asked her 21 year old roommate.

"Terrible!" the roommate answered. "He showed up in his 1932 Rolls Royce."

"Wow! That's a very expensive classic car. What's so bad about that?"

"He was the original owner."

Fair Play

One morning I was called to pick up my son at the school nurse's office. When I walked through the main entrance, I noticed a woman, curlers in her hair, wearing pajamas. "Why are you dressed like that?" I asked her.

"I told my son," she explained, "that if he ever did anything to embarrass me, I would embarrass him back. He was caught cutting school. So now I've come to spend the day with him!"

Two Lines.....

Up in Heaven there are two lines: One with a sign that says, "If you were henpecked, line up here", the other saying, "If you weren't henpecked, line up here."

One day St. Peter was looking at the new arrivals, and he saw the "Henpecked" line going on forever... while the "Non-henpecked" line only had 1 guy standing in it.

St. Peter walked up to him and said, "You mean to tell me you were never henpecked in your whole life??"

The guy said, "Well I don't know about that. All I know is this is where my wife told me to stand."
