Zoobiquity (26 page)

Finally, the bears were moved to a larger home. In this new environment, their food could be presented to them in ways that were “inconvenient,” causing them to mimic the foraging and hunting they’d do in the wild and expend more energy getting at a meal.

Yet even with all these changes, Watts was not able to wholly re-create the bears’ natural diet. Just as it would be almost impossible for us to eat like our ancestors did even a hundred or a thousand years ago, it’s unfeasible for zoos to duplicate a wild diet for each animal.
The fruit zookeepers buy from grocers and wholesalers is a far cry from the fruit a wild animal eats.

There are no naturally occurring banana plantations in the Canadian Rockies. No orange groves. No wild watermelon vines
or mango trees. And even if Watts could have gotten fruit with the same characteristics in the exact proportions to what is found in the wild, the microorganisms on that washed, boxed, refrigerated, and shipped fruit would be completely different from what the animal would be eating in a natural setting.

Fortunately, Watts understood that the fantasy of creating “the perfect wild diet” was just that—a fantasy. She did the best that she could under the circumstances. And it turned out that adjusting the bears’ diets in ways that were simply informed by knowledge of their natural ecology was enough. They lost weight. They seemed to feel better and have more energy. In short, they were healthier.

Watts’s success carries lessons we can apply to our own lives, whether we want to address the global obesity epidemic or a personal weight-loss effort. Researchers and doctors ought to consider the environment’s cyclical periods of abundance and scarcity as well as the seasons’ effect on our food-absorbing intestines. We must take seriously the complex universe of the microbiome and the metabolic consequences of infection. We need to think about global forces like day length and light cycles.

Modern, affluent humans have created a continuous eating cycle, a kind of “uniseason.” I’ve started calling this blissful, bountiful, yet static and superfattening environment the “eternal harvest.” Sugar is abundant, whether in our processed foods or in beautiful whole fruits that have had their inconvenient seeds bred out of them and that “unzip” from easy-to-peel skins and pop open into ready-to-eat segments. Protein and fat are everywhere available—in eternal harvest the prey never grows up and learns to run away or fight us off. Our food is stripped of microbes, and we remove more while scrubbing off dirt and pesticides. Because we control it, the temperature is always a perfect seventy-four degrees. Because we’re in charge, we can safely dine at tables aglow in light long after the sun goes down. All year round, our days are lovely and long; our nights are short.

As animals, we find eternal harvest an extremely comfortable place to be. But unless we want to remain in this state of continual fattening, with its accompanying metabolic diseases, we will have to pry ourselves out of this delicious ease.

Name a medical complaint or affliction, and you’ll find an online support group for it. These sites allow people to swap stories, share remedies, and feel less alone. The posts are often heartbreaking. Recently, I was scrolling through some online forums. The threads practically wailed with misery: “
I am so worried,” “This is tearing me apart,” “I am afraid he isn’t going to stop,” “I am at wits’ end,” “He’s had this problem for years,” “Can someone please help me?,” “I feel so terrible—like I am a horrible mommy.”

The sites were not about human patients. They were about pet birds with the surprisingly common problem known as “feather-picking disorder.” While the individual stories varied, the overall theme was the same. Birds with names like Juliet, Zeke, Jubilee, and Ms. Earl were all perfectly healthy, until one day their owners discovered a pile of colorful plumage at the bottom of the cage … and a bald patch on their pet’s shoulder or chest or tail. The birds were plucking out their feathers, one by one, and sometimes pecking the underlying skin until it bled. Veterinary exams ruled out physical causes of irritation, like mites or infections. The owners installed humidifiers, smoothed aloe vera on the stubbled skin, and invested in higher-quality birdseed. Still the picking
continued. One despairing owner of a self-plucking Quaker parrot wrote, “
Lately she has been pulling and letting out that little scream like they do when you touch the wrong pinfeather, then she goes right on and does it again, so now she’s plucking even if it HURTS … and I have seen several small spots of blood on her crop and under her wings.”

As a human physician and psychiatrist who’s never in my life owned a bird, I nonetheless recognized these symptoms: an inexplicable change in behavior, deliberate actions that caused bodily pain and disfigurement, and confusion and distress in loved ones. They brought to mind a patient I saw a couple of years ago, a twenty-five-year-old woman who presented with heart palpitations. Traversing her inner left forearm was a series of expertly cut incisions, ones that in other circumstances might have been the handiwork of one of my surgical colleagues. Thought had clearly gone into sterilization, cleanliness, and how the cuts would heal. But no doctor had been present when they were made. Instead, my patient had taken a razor in her right hand and sliced into her own skin. She was a “cutter.”

Cutting is probably our era’s most iconic form of human self-mutilation, seemingly tailor-made for suburban-parent hand-wringing and tabloid ogling.
Its name says it all, but in case you don’t know: it means taking something sharp—maybe a razor blade, scissors, broken glass, or a safety pin—and purposely slicing it across your skin to draw blood and create wounds. Usually, cutters target parts of their bodies that can be covered up with clothing to hide the evidence—say, their inner arms, thighs, or stomachs. Some do it impulsively, with whatever tool is at hand; others are more ritualistic about it. They might cut at the same time and in the same place every day. Or they create “kits” that hold their favorite cutting implement, along with gauze, Band-Aids, and alcohol wipes for mopping up afterward. As you can imagine, cutters—especially those who do it for many years—develop scars, often parallel lines like crimson ladder rungs up and down their favorite cutting site.

Psychiatrists call cutters “self-injurers” to include the whole range of inventive ways people dream up to hurt themselves. Some burn themselves on purpose with cigarettes, lighters, or tea kettles. Others bruise their skin by banging, punching, or pinching themselves. Those with trichotillomania rub and rip out hair on their heads, faces, limbs, and genitals. Some are swallowers, ingesting objects such as pencils, buttons, shoelaces, or silverware. We see this particular method a lot in prisons.

You may think self-injury occurs only in edgy subcultures or the seriously mentally ill. But my psychiatrist colleagues say it’s sweeping through the general population. Therapists and school guidance counselors confirm this.

Self-injury has gained an unintended endorsement by public figures.
I, for one, was shocked by Princess Diana’s disclosure to the BBC in 1995 that she cut herself with a lemon peeler and a razor blade. She also engaged in non-blade-related self-injury, including hurling herself into a glass cabinet and throwing herself down a flight of stairs.
While Angelina Jolie has restyled herself as a supermom and human rights crusader, she joined such other celebrities as
Christina Ricci,
Johnny Depp, and
Colin Farrell in telling the world about a self-injuring past; their tools included knives, soda can pop-tops, broken glass, cigarettes, lighters, and their own fingers. Cutting’s edgy street cred includes feature appearances in angsty teen films like
Thirteen
and
Girl, Interrupted
. And cutting even made a comic turn in the movie
Secretary
, with Maggie Gyllenhaal and James Spader embarking on what is perhaps the most happy-go-lucky sadomasochistic love story ever told.

But confronted by my cutter patient’s razor-notched arms, I was still confused. She was a thoughtful, intelligent adult woman with a respectable job, very much like the Maggie Gyllenhaal character in
Secretary
. Why would she cut herself
on purpose
—something a doctor would consider doing only with anesthetic and strict protocols? So although she was in my office for a heart consult, I asked her. She answered matter-of-factly, “My shrink says I’m trying to kill myself. But I’m not. If I wanted to die, I would. Cutting just makes me feel better. It relieves me.”

Her answer jibed with what other cutters say. A twenty-two-year-old woman writing on a Cornell University website put it this way: “
I began cutting my arms at the age of 12.… I think I could best describe the feeling I get as total bliss. It relaxes me.”

Bliss? Relaxation? Relief? It “
feels good
”? Even after years of psychiatry training and two decades around a hospital, I still think this sounds
incredible. But cutters and their therapists say it’s true.
And they confirm that most self-injurers are not suicidal, though sometimes a cutter will go too deep with the blade and require medical attention.

But as to
why
they do it, the short answer is that we don’t really know.
Psychiatrists have linked cutting to adolescence, control issues, emotional imperceptiveness, and an inability to talk about feelings. Self-injury has also been associated with childhood sexual abuse and such other mental conditions as borderline personality disorder, anorexia nervosa, bulimia nervosa, and obsessive-compulsive disorder (OCD). Patients who self-harm report being stressed and anxious, overwhelmed by expectations and choices—or completely isolated and numb.

Childhood traumas and abusive parents have traditionally been blamed for self-mutilating behavior. But this formulation, it turns out, is incomplete. The stereotypical cutter featured in movies and on TV may be a sexually abused, poorly parented borderline girl.
But it turns out that rates of self-injury may be roughly similar for men and women. The difference is more in how they do it: men tend to hit or burn themselves, while women usually cut.
Some begin the behavior as young adults when they’re no longer under the influence of their parents. And many report no history of childhood abuse.
