The Body Heretic: It Scorns Our Efforts

    THE promises are everywhere. Sure, you smoked. But you can erase all
    those years of abusing your lungs if you just throw away the
    cigarettes. Eating a lot of junk food? Change your diet, lose even 5
    or 10 pounds and rid yourself of those extra risks of heart disease
    and diabetes. Stay out of the sun - who cares if you spent your youth
    in a state of bronzed bliss? If you protect yourself now, skin cancer
    will never get you.

    Maybe it should be no surprise that America's popular and commercial
    cultures promote the idea of an inexhaustible capacity for
    self-rejuvenation and self-repair. After all, if America as an idea
    has meant anything, it has meant just that - the possibility of
    continual transformation - becoming wealthier, more spiritual, more
    beautiful, happier and feeling younger.

    That optimism has helped create a society of unmatched vitality - a
    source of bewilderment, alarm and envy to the rest of the world. But
    Americans often forget, or aren't aware, of how unusual they are in
    this respect, notes Dr. Daniel Haber, director of the cancer center at
    Massachusetts General Hospital.

    "I grew up in Europe and I travel in Europe," he said. "And there's an
    amazing contrast." Europeans are far more fatalistic about their
    lives, he said. They believe "you need to enjoy life," so they smoke,
    they bask in a sun, they take pleasure in a leisurely, indulgent meal
    and they don't feel compelled to go to a gym.

    Americans, Dr. Haber says, believe in control - of their bodies, their
    mental faculties and their futures. So shedding some pounds or some
    unhealthy habits is not merely sensible. It suggests a new beginning,
    being born again.

    Maybe that is why people may feel betrayed when Peter Jennings
    explains that he stopped smoking, at least for a while, and still got
    lung cancer. Or why, two decades after his death, people still talk
    about Jim Fixx, the running guru who lost weight, stopped smoking, ran
    every day and dropped dead of a heart attack.

    In fact, science is pretty clear on all of this: There are real limits
    to what can be done to reverse the damage caused by a lifetime of
    unhealthy living. Other than lung cancer, which is mostly a disease of
    smokers, there are few diseases that are preventable by changing
    behavior in midlife.

    But that is not what most people think, said Dr. Barnett Kramer, the
    associate director for disease prevention at the National Institutes
    of Health. Instead, they believe that if you reform you'll erase the
    damage, in part because public health messages often give that
    impression. "It is easy to overestimate based on the strength of the
    messages," Dr. Kramer said. "But we're not as confident as the
    messages state."

    Eating five servings of vegetables and fruit has not been shown to
    prevent cancer. Melanoma, the deadly skin cancer, occurs whether or
    not you go out in the sun. Gobbling calcium pills has not been found
    to prevent osteoporosis. Switching to a low-fat diet in adulthood does
    not prevent breast cancer.

    At most, Dr. Kramer said, the effect of changing one's diet or
    lifestyle might amount to "a matter of changing probabilities,"
    slightly improving the odds. But health science is so at odds with the
    American ethos of self-renewal that it has a hard time being heard.
    Here, where people believe anything is possible if you really want it,
    even aging is viewed as a choice.

    "It's hard to find an American who doesn't believe that, with enough
    will, he or she can achieve anything - we've been brought up to
    believe that," said Dr. Barry Glassner, a sociology professor at the
    University of Southern California. Health, he emphasized, is no
    exception: "It's the same whether you're 40, 50 or 80. It doesn't
    matter whether you are male or female, black or white. "

    But in matters of health, the strongest willed person simply cannot
    wipe the slate of life clean and begin again. This is true even with
    lung cancer and smoking. Those who quit may greatly reduce their risk
    of lung cancer. But they cannot eliminate it.

    "The best you can be is a former smoker - you can't be a 'never
    smoker,' " said Dr. Kramer. "It's not all or none. It's a matter of
    changing probabilities."

    In fact, in every area of desired physical self-renewal, the
    probabilities make it hard to argue that life allows one to start

    At health clubs, pear-shaped people in their 40's and 50's obsessively
    lift weights, trying for those defined muscles that, even in youth,
    come only to those with a certain genetic predisposition. But by
    middle age, the overweight tend to stay that way, and the body has a
    harder time increasing muscle mass. So even the greatest personal
    trainer will not produce rippling abs.

    At the cardiologist's office, middle-age men, learning that their
    arteries are starting to clog, swear they'll never eat chips and
    hamburgers again, and that they will take up jogging. Some do and a
    small percentage even stick with it. But no amount of exercise or diet
    change will make the plaque in their arteries disappear. Despite
    common public health recommendations, walking for half an hour a day,
    five days a week probably won't make most people lose weight. And
    while a regular regimen of walking or running will likely improve your
    stamina and cardiovascular fitness, there is no guarantee that it will
    reverse heart disease, prevent or forestall a heart attack or in any
    way extend your life.

    The effects of other measures, like changing lifestyle or switching to
    a diet rich in raw vegetables, are even less clear when it comes to
    preventing cancer, said Dr. Kramer. "Even if they do affect the
    cancer," he said, " it may be that it's over an entire lifetime."

    So what are Americans, with their faith in starting over, to do? When
    it comes to making oneself over, said Dr. Glassner, they have two
    options. One, he said, "is that you can consider yourself inadequate
    or inferior" for failing to force the years to melt away. The other is
    to shift the definition of rejuvenation from a arduous restructuring
    of the self to a paint job.

    "Now, instead of losing the weight you're going to go for cosmetic
    surgery," Dr. Glassner said.

    That is not really an answer. Collagen injections or surgery may give
    people more youthful looking faces, but only for a while. And
    liposuction won't help for long if the body restores the fat that was
    suctioned off the patient's arms or buttocks.

    Then there is a third possibility for the resourceful, Dr. Glassner
    said. An overweight person can simply redefine himself as a "food

    There is one group, however, for whom a strong sense of control over
    the future may be an unalloyed good: the sick.

    "Protective illusions," says Dr. Shelley Taylor, a psychology
    professor at the University of California at Los Angeles, can be a
    good thing. In her research, she found that among people with serious
    diseases, those who felt they still had control over their lives coped
    better with their illnesses.

    The optimists fared better psychologically even when they became more
    ill - shattering the illusion of control. "What you often see is
    people use something like cancer as an opportunity to discover value
    in their lives, and meaning," Dr. Taylor said. "They reorder their
    priorities. They focus on relationships more. Control and optimism
    shift to things that can be dealt with."

    For those in good health, there is still another option, though it is
    decidedly a minority position. This is simply to scale back on one's
    self-engineering and take more pleasure in simply getting from day to

    The American essayist Joseph Epstein nicely expressed this view in an
    essay, written when he hit the age of 60, which he gave the mordant
    title, "Will You Still Feed Me?" In it, Mr. Epstein expresses the
    virtue of just enjoying the ride.

    "At 60," he writes, "one probably does well not to expect wild
    changes, at least not for the better. Probably best not even to expect
    a lot in the way of self-improvement. Not a good idea, I think, at
    this point to attempt to build the body beautiful. Be happy-immensely
    happy, in fact-with the body still functional."

    Of course, many in midlife will still decide to hit the gym, to eat
    better, drink less, relax more. And that's a good thing, if only
    because they will feel better for being fitter. But they shouldn't
    expect it to erase the effects of all those years that came before.
