Because of the increased obesity and inactivity in the United States these days, it is possible that we will lose, as a country, all the health gains of the last fifty years. Some economists suggest that we could lose it in a single generation. This is frightening when you consider, for instance, that physical health is related to dementia. We might see an increase in the rates of dementia and Alzheimer’s disease. Right now, a conservative estimate is that a quarter of the population over eighty will get Alzheimer’s. Reports show that by midcentury as many as fifty million older Americans may get the disease. While research is under way to prevent or postpone Alzheimer’s, scientists already know that people in their sixties can reduce their risk of Alzheimer’s—by half!—through exercise. This is why, when I work out, I am not just thinking about my body; I’m also thinking about my brain. I want to do everything I can to maintain it, so that if I am one of the fifty million Americans who will get Alzheimer’s, it won’t happen until I am ninety or older, as opposed to when I am eighty-two.
Challenge the Brain
Dr. Denise Park says that “if you are living a life with a high degree of engagement in activities that are cognitively demanding, it may delay the onset of Alzheimer’s a little bit—delay it, not change it. You might still be diagnosed, but putting it off by a couple of years extends your quality of life and benefits you, your family, and even our health care system.”
When it comes to cognitive function—or brain health—education plays a strong role. This is partly because early education positively affects brain circuitry. Also, a well-educated person will tend to engage more in mentally stimulating activities such as reading, chess, and ongoing learning. Higher incomes and mentally challenging types of work also contribute to maintaining one’s cognitive ability.
At a seminar on longevity, Dr. Park explained,
tasks will improve cognition if they continually challenge the cognitive system by making sustained demands on executive function over a prolonged period of time and are relatively novel for the individual performing the task. Just like the person who has had a stroke has to use a different hand to perform tasks to develop new neural networks, it is plausible that performing other novel tasks will do the same for a healthy aging brain. As an example, we think learning to quilt could be stimulating for someone who never sewed before. If you are already an expert quilter, I would suggest learning a musical instrument or some other skill that you find both challenging and fun. It is critical to keep learning and adapting new sequences of complex behaviors. Have fun and try a new domain that broadly stimulates some new neural networks.
“The other thing that people underestimate,” continued Dr. Park,
is the unique demands of social interactions. In a social situation, it’s really inappropriate not to remember someone’s name, or what they told you the day before about their grandchildren, and there is thus actually quite a bit of cognitive demand. I would put social interaction as an important element of stimulation. To enhance cognition, you need to be productively engaged in activities that demonstrate sustained activation of your working memory, reasoning, and other higher-order cognitive functions. These are all primarily frontal cortex functions—the most flexible, plastic area of the brain you have to be using those areas of the brain. Think of a guy who is multitasking at work. He’s on the phone; he’s at the computer; he is planning for his upcoming meeting. This would be very demanding of neural function, and I would venture to guess that this productive engagement would enhance cognition (as long as the stress level did not become destructively high). The couple that’s familiar with each other, sitting around and having a great time at the beach, chatting and telling old stories, are probably not facilitating their cognition very much.
Here are some examples of brain exercises you might consider:
learn anything new: a new language, a new hobby, a musical instrument;
meet new people who involve you in conversation;
memorize poetry;
learn new words every day;
…and, as I have said, get physically active. All of these activities can be successfully begun anytime, including later in life.
One more thing: Estrogen therapy, if begun while a perimenopausal woman is in her late forties or early fifties, can improve and protect the brain. Hormone replacement is so controversial, and its effects vary with the individual, so it’s best to consult a doctor. Still, Cynthia Gorney wrote in the New York Times Magazine, “It makes new cells grow. It increases what’s called ‘plasticity,’ the brain’s ability to change and respond to stimulation. It builds up the dendrites and number of dendritic spines, the barbs that stick out along the long tails of brain cells, like thorns on a blackberry stem, and hook up with other neurons to transmit information back and forth. The thinning of those spines is a classic sign of Alzheimer’s.”2
In the next chapter, I will tell you some really good and interesting news about aging.
CHAPTER 9
Positivity: The Good News Is You’re Getting Older!
We are all happier in many ways when we are old than when we are young. The young sow wild oats. The old grow sage.
—WINSTON CHURCHILL
GUESS WHAT? YOU CAN PRETTY MUCH EXPECT TO BE HAPPIER at eighty than you were at twenty! Regardless of whether you are male or female, married or single, employed or not, or have your children living with you! Regardless, in other words, of events in your life. Surprising, huh? Especially given all the things that can start to go south with age—for example, buttocks, joints, valves, skin, hairlines, and social networks!
Nonetheless, a 2008 Gallup poll showed this result after interviewing 340,000 Americans aged eighteen to eighty-five. Dr. Arthur A. Stone, a professor of psychology at the State University of New York at Stony Brook, who led the study based on the poll, isn’t sure why this uptick in well-being occurs.1 Could it be psychological changes? Alterations in brain chemistry or endocrine changes? No one really knows. What appears to be certain is that between the ages of eighteen and fifty, those interviewed tended to feel more sadness, stress, worry, and anger—and then, vavoom, beginning at fifty, life seemed to take an upward turn.
This has been my personal experience as well, although I became more aware of it at age sixty than at fifty. As I said in an earlier chapter, one of my main character traits as a younger person was a tendency to melancholy. On top of that, I was wound pretty tight. The ten years I spent with Ted Turner (from ages fifty-two to sixty-two) taught me more about laughter and letting go than almost anything ever had before. In fact, I’ll tell you a secret: I wouldn’t have been able to be as funny playing Jennifer Lopez’s mother-in-law in Monster-in-Law had I not had that time with Ted, who made it possible for me to learn to laugh at the outrageous and to see that over-the-top can be endearing.
But it has been more than ten years now that Ted and I have been apart—from ages sixty-two to seventy-two—and I continue to notice how much more positive I have become … joyful, even. Most things that would have run me up the wall with anxiety or sent me to bed with depression roll right off my back now. Very few things really stress me anymore. Well, children and grandchildren can still cause stress! As they say, “You are only as happy as your least happy child.” But for me, it’s not anywhere near what it used to be, and when stress comes, it doesn’t linger.

Dr. Ken Matheny, Regents Professor in Georgia State University’s Department of Counseling and Psychological Services, which he founded in 1966, told me that one of the premier sources of information about centenarians in the country is the Institute of Gerontology, at the University of Georgia in Athens. “There are now about fifty-six thousand Americans who are centenarians,” he said, “and when they study these folks, they find that on the whole they report more happ
iness than the average person. Which is startling, isn’t it?”
Come to think of it, the oldest people I have interviewed for this book have one striking thing in common: a sense of humor. For instance, ninety-five-year-old Karl. When I asked him for his age, he said, “I don’t know how old I am, but I was around when the Dead Sea was only sick.” When 104-year-old Cal Evans was asked by a Denver reporter, “Have you lived in Denver all your life?” Cal laughed and answered, “Not yet, sonny.” And there was Jeanne Louise Calment of Arles, France, the longest-lived person on record. Born in 1875, she died at 122 years and four months. She is reported to have quipped at age 119, “I have only one wrinkle, and I am sitting on it.” At one of Jeanne’s last birthday parties, in Paris, a journalist said with great hesitancy in his voice, “Well, I guess I will see you next year,” to which she responded, “I don’t see why not; you look to be in pretty good health to me.”
The Zen priest Joan Halifax and I were discussing the various ways in which our bodies are starting to weaken. “Yes,” she said at age sixty-five, “on some level, certain aspects of my life are shrinking. But as they shrink, something else expands, and there seems to be this compensation.”
“Give me an example,” I said.
“Well, my sense of humor has expanded. My robustness has expanded. My tolerance and patience have expanded. My love of people and of my work and of the earth has expanded. Younger people tend to get more obsessed over little details,” Joan explained, “whereas older people tend to just find out what is important.”

“They don’t sweat the small stuff,” I said.
“That’s right. And on the other side of the equation, I think aging has stripped away a lot of my fear.”
I had heard the same thing from the writer Erica Jong. “I am much more relaxed now,” Erica told me over lunch in her art-filled New York apartment. “I am much less uptight. I know that things are not personal. If somebody criticizes something I have written, if somebody says something vicious about me, I think it is funny and I think it’s about them, not about me. I hadn’t gotten there earlier. After Fear of Flying I nearly dried up and stopped writing because the attacks were so vicious.”
At a breakfast meeting in Ann Arbor, Michigan, I told Dr. Marion Perlmutter about my own growing sense of peace and detachment. “I hate to even use that word, ‘detachment,’ ” I said, “because it can be interpreted as noncaring when, in fact, I do care about most things just as much as ever.”
Dr. Perlmutter, who is with the Department of Psychology at the the University of Michigan, answered me: “I understand. As a scientist, I not only know more things about the brain, but I appreciate more all of the things I do not know. It is that, perhaps, the appreciation of the limitations of our knowledge, that has us detach a little bit and maybe moves us to something spiritual. Knowing what you don’t know is the first stage of knowing. But I think that only in late life does that part of understanding kick in. And this, I think, helps us detach.”
Dr. George Vaillant, director of the Harvard Study of Adult Development, discovered that older people develop “mature defenses.” By this he means the ability to turn lemons into lemonade and to not turn molehills into mountains.2
Dr. Laura Carstensen, founding director of the Stanford Center on Longevity, says that while there are some older people who don’t show a “Positivity effect” at all, and some younger people who do, generally Positivity represents an important developmental shift, a way to approach life that is expressed through humor, gratitude, forgiveness, playfulness, creativeness, and flexibility. “Goals change as people age,” she told me. “There are so many what-ifs in the lives of younger people, whereas we are armed with a long backward look—‘this has happened before.’ ”
Dr. Perlmutter agrees that Positivity may be due to “the accumulation of perspective. The first time that something happens, like financial loss, for instance, it is horrible. But after you have seen cycles of something like that happening, you have some perspective that this doesn’t mean the end of life. It just means a new challenge that we will get through.” All of these psychologists seem to agree that the “this too shall pass” view of life is a hard one for young people—and many in midlife as well—to fully accept; less so, for folks in Act III.
During a meeting in Atlanta, Dr. Matheny told me, “Life has shown you that you survived before, you’ll survive again. And since you now are no longer competing like you were earlier, there is not as much hypervigilance, there are more acceptances, letting things develop. You can’t possibly oppose every force that comes up, every little problem that you’ve got, and so learning to accept and, I think, accommodate and adjust is every bit as important as mastery because you can’t master that many things. So it is like martial arts—if the force comes, you don’t oppose it, you just try to guide it. And I think there is something of that that happens with age.”
Dr. Carstensen concurs. “Elders tend to know what they want and need to make their lives richer and deeper, and they are able to discard what they no longer need,” she told me.
We are less apt to be thrown by outside events. When people are very young they have long and nebulous futures ahead of them and all sorts of information might be useful even though it might not be useful immediately. It is very informative to know where the tiger is hiding in the brush. But once you know that, you don’t have to keep going back to visit the brush. You don’t need to spend so much time preparing, you just know. So as the future becomes shorter, you know what information is relevant to your goals and what isn’t because your goals are clearer; you know what you are focused on; you know what is important and what is not; you can separate the wheat from the chaff, so to speak. What is relevant to your goals you will learn quickly and you’ll let the rest go. I’ve spent the last thirty years investigating the psychology of aging and my research consistently shows that, in terms of emotions, the best years come late in life.… Older people as a group suffer less from depression, anxiety, and substance abuse than their younger counterparts. In everyday life, they experience fewer negative emotions but just as many positive ones as people in their twenties and thirties—the people we stereotypically think of as the most happy.3
Carstensen also notes that seniors are less apt to bear grudges and that they pick their fights carefully, which is why we make good mediators and facilitators.
Many psychologists have identified the Positivity of aging. According to John Gabrieli, a professor of cognitive neuroscience at the Massachusetts Institute of Technology, “As people get older, they seem to be willing to accept things that, when we’re young, we would find disturbing and vexing.” Betrayal, for instance, is so hard to accept when we are young. But Dr. Gabrieli believes that seniors may be more able to see things from the other person’s perspective and thus don’t view certain actions as betrayal. He says, “It paves the way for you to be sympathetic to the situation from his perspective, to be less disturbed from her perspective.” He calls this “compassionate detachment,” which doesn’t mean not caring or that we’ve become bankrupt of certitudes. It means having no personal agenda, no ego stake in outcomes. This means that with age, we can be more trustworthy—it’s easier for us to see all sides and give advice that comes more from our heart than from our ego.
As I learned about the Positivity that seems to come with age, it began to feel more and more like wisdom. Experts on such things have never quite come to an agreement on what constitutes wisdom or whether we get wiser with age, but the descriptions of it that resonate with me include:
The ability to step outside oneself and assess troublesome situations with calm reflection.
The ability to regulate our emotions.
Knowing what is nonessential and letting it go. The philosopher and psychologist William James observed, “The art of b
eing wise is the art of knowing what to overlook.”
The willingness to embrace uncertainty.
Though I know young people who demonstrate some or all of these qualities, I cannot help but feel that these are attributes that tend to come to the fore as we age and gain experience. Mary Catherine Bateson says, “Experience doesn’t make people wise. It is reflection on experience that makes us wise.” Many of us don’t take time to reflect until age provides us the time to do it. Doing a life review forces us to reflect on our experiences; thus, I believe, it can help lead us to wisdom.
I asked Dr. Matheny why he thought some seniors can adjust and adapt to the challenges of age with humor when others can’t. Is it possible, I asked, to get better at that if it hasn’t been your character style?
“Look, an awful lot of people suffer terribly in old age, so I’m not judging anybody,” he replied. “I am sure that being positive is not all just a matter of willpower. In other words, there is a whole history of conditioning experiences people have—in childhood and throughout their entire lives. So it’d be cruel to say that you should just be able to be positive. But I think this is where you want to get to if you can, and apparently a lot of centenarians have.”
After listening to all these experts, I realized that my being able to experience Positivity is, in part, simply because I am older. But I have also worked at it. Doing my life review helped a lot. There is something wonderful about self-examination—looking, devoting enough time and energy, interest, and psychological openness to understand what your trajectory was that made you who you are today. The next step is taking responsibility for it, owning it. Physical exercise, which releases feel-good endorphins, helps with Positivity, and so, for me, does meditation.
