THE PUZZLING GAP BETWEEN HOW OLD YOU ARE AND HOW OLD YOU THINK YOU ARE

T his past thanksgiving , I asked my mother how old she was in her head. She didn’t pause, didn’t look up, didn’t even ask me to repeat the question, which would have been natural, given that it was both syntactically awkward and a little odd. We were in my brother’s dining room, setting the table. My mother folded another napkin. “Forty-five,” she said.
She is 76.
Why do so many people have an immediate, intuitive grasp of this highly abstract concept —“subjective age,” it’s called—when randomly presented with it? It’s bizarre, if you think about it. Certainly most of us don’t believe ourselves to be shorter or taller than we actually are. We don’t think of ourselves as having smaller ears or longer noses or curlier hair. Most of us also know where our bodies are in space, what physiologists call “proprioception.”
Yet we seem to have an awfully rough go of locating ourselves in time. A friend, nearing 60, recently told me that whenever he looks in the mirror, he’s not so much unhappy with his appearance as startled by it—“as if there’s been some sort of error” were his exact words. (High-school reunions can have this same confusing effect. You look around at your lined and thickened classmates, wondering how they could have so violently capitulated to age; then you see photographs of yourself from that same event and realize: Oh .) The gulf between how old we are and how old we believe ourselves to be can often be measured in light-years—or at least a goodly numb.
As one might suspect, there are studies that examine this phenomenon. (There’s a study for everything.) As one might also suspect, most of them are pretty unimaginative. Many have their origins in the field of gerontology, designed primarily with an eye toward health outcomes , which means they ask participants how old they feel, which those participants generally take to mean how old do you feel physically , which then leads to the rather unsurprising conclusion that if you feel older, you probably are, in the sense that you’re aging faster.
But “How old do you feel?” is an altogether different question from “How old are you in your head?” The most inspired paper I read about subjective age, from 2006, asked this of its 1,470 participants—in a Danish population (Denmark being the kind of place where studies like these would happen)—and what the two authors discovered is that adults over 40 perceive themselves to be, on average, about 20 percent younger than their actual age . “We ran this thing, and the data were gorgeous,” says David C. Rubin (75 in real life, 60 in his head), one of the paper’s authors and a psychology and neuroscience professor at Duke University. “It was just all these beautiful, smooth curves.”
Why we’re possessed of this urge to subtract is another matter. Rubin and his co-author, Dorthe Berntsen, didn’t make it the focus of this particular paper, and the researchers who do often propose a crude, predictable answer—namely, that lots of people consider aging a catastrophe, which, while true, seems to tell only a fraction of the story. You could just as well make a different case: that viewing yourself as younger is a form of optimism, rather than denialism. It says that you envision many generative years ahead of you, that you will not be written off, that your future is not one long, dreary corridor of locked doors.
I think of my own numbers, for instance—which, though a slight departure from the Rubin-Berntsen rule, are still within a reasonable range (or so Rubin assures me). I’m 53 in real life but suspended at 36 in my head, and if I stop my brain from doing its usual Tilt-A-Whirl for long enough, I land on the same explanation: At 36, I knew the broad contours of my life, but hadn’t yet filled them in. I was professionally established, but still brimmed with potential. I was paired off with my husband, but not yet lost in the marshes of a long marriage (and, okay, not yet a tiresome fishwife). I was soon to be pregnant, but not yet a mother fretting about eating habits, screen habits, study habits, the brutal folkways of adolescents, the porn merchants of the internet.
I was not yet on the gray turnpike of middle age, in other words.
“I’m 35,” wrote my friend Richard Primus, 53 in real life and a constitutional-law professor at the University of Michigan Law School. “I think it’s because that’s the age I was when my major life questions/statuses reached the resolutions/conditions in which they’ve since remained.” So: kind of like my answer, but more optimistically rendered. He continued: “Medieval Christian theologians asked the intriguing question ‘How old are people in heaven?’ The dominant answer: 33. Partly bc age of Jesus at crucifixion. But I think partly bc it feels like a kind of peak for the combined vigor-maturity index.”
The combined vigor-maturity index: Yes!
Richard was replying to me on Twitter, where I’d tossed out my query to the crowd: “How old are you in your head?” (Turns out I’m not the only one with this impulse; Sari Botton, the founder of Oldster Magazine , regularly publishes questionnaires she has issued to novelists, artists, and activists of a certain age, and this is the second question .) Ian Leslie, the author of Conflicted and two other social-science books (32 in his head, 51 in “boring old reality”), took a similar view to mine and Richard’s, but added an astute and humbling observation: Internally viewing yourself as substantially younger than you are can make for some serious social weirdness.
“30 year olds should be aware that for better or for worse, the 50 year old they’re talking to thinks they’re roughly the same age!” he wrote. “Was at a party over the summer where average was about 28 and I had to make a conscious effort to remember I wasn’t the same—they can tell of course, so it’s asymmetrical.”
Yes. They can tell. I’ve had this unsettling experience, seeing little difference between the 30-something before me and my 50-something self, when suddenly the 30-something will make a comment that betrays just how aware she is of the age gap between us, that this gap seems enormous, that in her eyes I may as well be Dame Judi Dench.
Although many hewed close to the Rubin-Berntsen rule, the replies I got on Twitter were not always about potential. Many carried with them a whiff of unexpected poignancy. Trauma sometimes played a role: One person was stuck at 32, unable to see themselves as any older than a sibling who’d died; another was stuck for a long time at age 12, the year her father joined a cult. (Rubin has written about this phenomenon too—the centrality of certain events to our memories, especially calamitous ones. Sometimes we freeze at the age of our traumas.)
My friend Alan, who is in his 50s, told me he thinks of himself as 38 because he still thinks of his 98-year-old father as 80. The writer Molly Jong-Fast replied that she’s 19 because that’s the age she got sober. One 36-year-old woman told me she thought the pandemic was a time thief—she simply hadn’t accumulated enough new experiences to justify the addition of more chronological years—which made her younger in her head sometimes, as if she were willing back the clock.
When I mentioned to a colleague that I was writing this piece, he told me he was 12 in his head, not because he thinks of himself as a child, but because his inner self has remained unchanged as he’s aged; it’s “the same consciousness as always since I became conscious.” His words instantly brought to mind a line from the opening pages of Milan Kundera’s Immortality : “There is a certain part of all of us that lives outside of time.”
Of course, not everyone I spoke with viewed themselves as younger. There were a few old souls, something I would have once said about myself. I felt 40 at 10, when the gossip and cliquishness of other little girls seemed not just cruel but dull; I felt 40 at 22, when I barely went to bars; I felt 40 at 25, when I started accumulating noncollege friends and realized I was partial to older people’s company. And when I turned 40, I was genuinely relieved, as if I’d finally achieved some kind of cosmic internal-external temporal alignment.
But over time, I rolled backwards. Other people do this too, just starting at a younger age—25—and Rubin has a theory about why this might be. Adolescence and emerging adulthood are times dense with firsts (first kiss, first time having sex, first love, first foray into the world without your parents’ watchful gaze); they are also times when our brains, for a variety of neurodevelopmental reasons, are inclined to feel things more intensely, especially the devil’s buzz of a good, foolhardy risk. The uniqueness and density of these periods have manifested themselves in other areas of Rubin’s research. Years ago, he and other researchers showed that adults have an outsize number of memories from the ages of about 15 to 25. They called this phenomenon “the reminiscence bump.” (This is generally used to explain why we’re so responsive to the music of our adolescence—which in my case means my iPhone is loaded with a lot more Duran Duran songs than any dignified person should admit.)
Rubin and Berntsen made a second intriguing discovery in their work on subjective age: People younger than 25 mainly said they felt older than they are, not younger—which, again, makes sense if you’ve had even a passing acquaintance with a 10-year-old, a teenager, a 21-year-old. They’re eager for more independence and to be taken more seriously; in their head, they’re ready for both, though their prefrontal cortex is basically a bunch of unripe bananas.
In Rubin and Berntsen’s 2006 study, socioeconomic status, gender, and education did not significantly affect their data. One wonders if this has something to do with the fact that they conducted their research in Denmark, a country with substantially less income inequality and racial heterogeneity than our own.
The picture changes when there’s more variety: A 2021 meta-analysis of 294 papers examining subjective-age data from across the globe found that the discrepancy between chronological age and internal age was greatest in the United States, Western Europe, and Australia/Oceania . Asia had a smaller gap. Africa had the smallest, which could be read as an economic sign (poverty might play a role) but also a cultural one: Elders in collectivist societies are accorded more respect and have more extended-family support.
“Could it be that feeling younger is actually dysfunctional and no longer helping you focus on what’s going on? That’s the more complicated question,” says Hans-Werner Wahl (69 in real life, 55 in his head), a co-author of the meta-analysis. “A lower subjective age may be predictive of better health. But there are other populations around the globe for whom it is not necessary to feel younger. And they’re not less healthy.”
This seems to be the conclusion of Becca Levy, a professor of epidemiology and psychology at the Yale School of Public Health. As a young graduate student, she went to Japan and couldn’t help noticing not just that people lived longer, but that their attitude toward aging was more positive—and her decades of research since have shown a very persuasive connection between the two. In the introduction to her book, Breaking the Age Code , she describes newsstands in Tokyo lined with manga books filled with story lines about older people falling in love. She reports wandering Tokyo on Keiro No Hi, or “Respect for the Aged Day,” and seeing people in their 70s and 80s lifting weights in the park. She talks about music classes filled with 75-year-olds learning how to play electric slide guitar.
At first blush, Levy’s scholarship may seem to quarrel with the literature of subjective age. But maybe it’s a complement. What underpins them both is an enduring sense of agency: If you mentally view yourself as younger—if you believe you have a few pivots left—you still see yourself as useful; if you believe that aging itself is valuable, an added good, then you also see yourself as useful. In a better world, older people would feel more treasured, certainly. But even now, a good many of us seem capable of combining the two ideas, merging acceptance of our age with a sense of hope. When reading over the many Oldster questionnaires, I was struck by how many people said that their present age was their favorite one. A reassuring number of respondents didn’t want to trade their hard-earned wisdom—or humility, or self-acceptance, whatever they had accrued along the way—for some earlier moment.
Recently, I wrote to Margaret Atwood, asking her how old she is in her head. In the few interactions I’ve had with her, she seems quite sanguine about aging . Her reply:
At 53 you worry about being old compared to younger people. At 83 you enjoy the moment, and time travel here and there in the past 8 decades. You don’t fret about seeming old, because hey, you really are old! You and your friends make Old jokes. You have more fun than at 53, in some ways. Wait, you’ll see!
Single malt of course
I've found that broken bones are a pretty good indicator in determining the difference between my mental age and physical age...
I’m 14 months out from 70 and trying to decide what I want to be when I grow up.
I woke last night to the sound of thunder
How far off I sat and wondered?
Started hummin' a song from 1962
Ain't it funny how the night moves?
When you just don't seem to have as much to lose
Strange how the night moves
With autumn closin' in
what I want to be when I grow up
At 68 still trying to figure that out.
... didn't they have any black ones shaped like a seal, or are those only available at the tourist shops?
I'm 86 and I damn well feel like it. My brother is 90 and I'm hoping to catch up with him.
Having not paid any attention to my age for well over 50 years and going on feelings both physical and mental (both being liars), I had to look it up. Yikes I’m 73 … gee thanks Google! How old I feel these days is a minute by minute head to/or feet experience that is rarely in coordination and woe be me when they are … the conundrum of being too young to die and too old to live takes aim and there better be a Scotch-like substance close by.
