Hi, this is Ray.

Let me tell you about my Aunt Linda. (Not her real name… she would absolutely kill me if I used her real name in a newsletter, even though she'd then secretly forward it to her entire book club.) Aunt Linda decided, at 67, that she wanted to learn the cello. Not "play the cello a little." Not "try the cello to see if she liked it." Learn. The. Cello. With actual lessons, actual practice, actual recital ambitions. She had played piano as a child, abandoned music in her twenties, and not seriously played any instrument since.

When she announced this at a family dinner, the response from the table was, charitably, mixed. There were polite smiles. There were "good for yous" with the slight tilt of the head that means "we're being supportive but we don't believe this." My uncle made a joke about her arms not being long enough, which, accurate or not, did not improve her mood. Several people privately told me they thought she was setting herself up for disappointment. The cello is hard. She was 67. The window had closed.

Three years later, Aunt Linda played in a small recital at her music school. She wasn't Yo-Yo Ma. She wasn't going to win any competitions. But she played a piece by Bach, with her hands and her arms and her brain that everyone had assumed were too old to learn this, and she did it well enough that the audience clapped sincerely instead of politely. She has since added another piece to her repertoire. She is, by any reasonable definition, a cellist now. At 70. Started from approximately scratch. Built it from there.

I think about Aunt Linda constantly when I encounter the "I'm too old to learn this" thought in myself or others. Because the cultural script around adult learning is so wrong, and so toxic, and so much in the way of what people could actually do with their lives. Today's newsletter is about why that script is wrong, what the actual research says about adult brains learning new things, and (because I'd be doing you a disservice without it) the honest version of what's harder later in life and what to do about it. Let's get into it.

Let me start with the foundational fact that destroys most "too old to learn" thinking. Your brain remains capable of structural and functional change throughout your entire life. This isn't motivational fluff. This is measurable, replicated neuroscience.

According to a Mayo Clinic Press summary of the research, though the number of neurons may decline with age, emerging research has shown that neuroplasticity helps the brain retain its ability to adapt both structurally and functionally throughout life. In short, neuroplasticity means you can retrain your brain, tap into new skills and maybe even learn a new language, no matter your age. The brain doesn't lock at 25 or 30 or 60. It keeps rewiring in response to experience and challenge for as long as you keep giving it experience and challenge.

The neuroscience research community has actually overturned a lot of older assumptions about adult brains over the past 20 years. As one summary of the field noted, the latest research challenges the older notion that healthy cognitive aging results in the loss of neurons… in fact, new brain cells emerge in memory centers of the brain, well into old age, and neuroplasticity persists throughout life and can even be enhanced through environmental factors. New neurons. In memory centers. Well into old age. The brain you have at 70 is not the brain you have at 25, but it's still actively building new infrastructure when you give it reason to.

This isn't theoretical. Researchers have been documenting it in the lab for decades now. Stroke patients in their 60s and 70s recover language and motor function through neuroplastic adaptation. Older adults learning instruments show measurable changes in their brain structure. People starting from scratch in their 60s, 70s, even 80s continue to demonstrate that the underlying machinery of learning is functional. The "use it or lose it" maxim turns out to be quite literal: brains that keep getting challenged keep adapting. Brains that don't, slowly stop. The variable that matters most isn't age. It's whether you're still asking the brain to learn.

Here's a piece of research that fits Aunt Linda's case so well I had to share it. In late 2025, researchers from the University of Nebraska published findings from a study on language learning in older adults. They took 41 monolingual participants aged 60 to 80, put them through an online language-learning program for 90 minutes a day, five days a week, for four months, and then measured both their performance and changes in their brain structure.

The results were striking. According to the researchers, behavioral results suggest that all participants successfully learn their language of choice with an average performance score of 96% in the post-intervention proficiency test, and neuroimaging analyses revealed structural brain alterations in regions implicated in working memory, attention, cognitive control, executive functions, and language processing. Average performance score: 96%. In adults between 60 and 80. Learning a brand new language from scratch.

Read that again. The popular myth says these participants shouldn't have been able to do this well. Their brains should have been "too old" to acquire new linguistic patterns. The research says they did it, and their brains physically changed in the process to support what they were learning. Same brains. Same general neuroscience that supposedly limits older learning. Different result, because they actually engaged in the learning. The limitation was never structural. It was behavioral.

This is what gets me about so many "too old to learn" beliefs. They're empirically falsifiable, and they keep getting falsified, and yet the cultural narrative keeps repeating them. The research has been pointing the other direction for at least 20 years. Most people have just never been told.

Now let me give you the honest other side, because I think the "you can do anything at any age!" framing is also wrong in its way, and you deserve the real picture.

Some specific aspects of learning DO get harder with age. Raw processing speed slows down for most people, which means rapid-paced learning environments (the kind that work well in your 20s) often don't fit as well later. Working memory capacity tends to slip somewhat. The ability to learn purely abstract, decontextualized material without much hook to existing knowledge does become harder when you have less existing scaffolding to attach it to.

Motor learning research provides a particularly clean example. A comprehensive review of aging and motor learning concluded that in the aging population, motor performance typically declines, characterized by slower and less accurate movements; however, despite these age-related changes, older adults maintain the capacity for skill improvement through training, and skill acquisition is accompanied by neural changes. The two-part finding is the key. Yes, baseline motor performance declines with age. AND the capacity for further improvement through practice is preserved. Older adults can absolutely learn new motor skills. They may not get to the level a 20-year-old could reach with the same training time. But the trajectory of improvement is real. The brain still adapts in response to practice.

A direct comparison of motor learning between younger and older adults found a similar pattern. According to one study, in both younger and older adults, motor performance shortened significantly during motor learning, with younger adults showing bigger reductions. Younger learners gained more per session, but older learners still gained. The slope of improvement was different. The improvement itself was real for both groups.

So the honest version is: learning later in life often takes longer, requires more deliberate practice, benefits from being structured well, and may not get you to the absolute peak you could have reached starting at 18. AND you can still genuinely learn new skills, develop new abilities, and build real proficiency at almost any age that you're willing to put in the work.

The question is never "can I learn this." The question is "am I willing to put in the work, given the rate at which I can expect to progress." The answer to that question is yours to decide. But you should at least make the decision based on accurate information, not on a folk neuroscience that was outdated 20 years ago.

Let me get specific about what late-life learning typically actually looks like, since the abstract picture sometimes obscures the practical reality.

You'll be slower than younger learners initially. This will be frustrating. You'll do an exercise, watch a video, try a problem… and you'll have to rewatch, redo, retry more often than you would have at 22. This is real. It's also recoverable through patience and consistency. The first few weeks of any new skill at any age involve a lot of "wait, what?" The wait-what phase is just longer for older learners.

Your existing knowledge will help you more than you think. As I covered in a previous newsletter on adult learning, the prior knowledge you've accumulated over decades is one of the most powerful learning aids you have. Every skill you've previously mastered, every domain you've previously explored, becomes attachment material for the new thing. Aunt Linda had played piano as a child. That was 50 years before she picked up the cello. The piano experience still helped. She had musical concepts, rhythm, basic notation, ear training… not at performance level, but in her bones. Those didn't evaporate. They were waiting to scaffold the new skill.

Your motivation regulation will be better than a younger person's. One of the cognitive abilities that actually IMPROVES with age, according to recent reviews, is the ability to direct your effort toward goals you've chosen even when the work is hard. You're better at sticking with things you care about than you were at 22, even if your raw cognitive horsepower has slipped slightly. For self-directed learning projects, this is enormous. Most ambitious learning projects fail because of motivation collapse, not capacity limits. You're better-equipped to handle the motivation part now than you were earlier.

You'll need to take care of the foundations more deliberately. Sleep, exercise, hydration, stress management, social connection… all the things I've covered in previous newsletters. These matter at every age, but they matter MORE as you age. The same level of foundational neglect that a 22-year-old can absorb without much consequence will sink a 65-year-old learning project. Build the infrastructure. Defend it.

You'll plateau and recover, plateau and recover. This is actually true for learners at any age, but the plateaus often feel more dispiriting later in life because of the "see, I knew I was too old" narrative running in the background. Don't listen to it. Plateaus are part of how learning works, regardless of age. They pass. The improvement resumes. Trust the process.

Here's where it gets bigger. The "I'm too old to learn that" belief doesn't just stop you from learning specific things. It quietly shapes how you live the rest of your life.

People who believe they're too old to learn new things stop trying new things. They contract their world. They stop meeting new people through hobbies they're not pursuing. They stop traveling to places that would require them to navigate unfamiliar contexts. They stop engaging with new ideas that would require updating their mental models. They become smaller, quieter, less curious versions of themselves over time. Not because they had to. Because they internalized a story that was wrong.

The research on cognitive aging actually suggests this contraction itself accelerates decline. As one Mayo Clinic Press summary noted, research suggests that the phrase "use it or lose it" applies to your brain and cognitive abilities, and you can build up your cognitive reserve through moderately challenging activities that engage your brain. The people who keep learning, keep being able to learn. The people who stop, start losing the capacity. The belief that you're too old becomes self-fulfilling not because the belief was right, but because acting on it actually does the damage the belief predicted.

This is the deeper reason to push back on the "too late" framing. It's not just about whether you can learn the cello at 67. It's about whether you can be the kind of person who is still adding new dimensions to themselves at 67, 75, 85. That person ages much better, in measurable cognitive ways, than the person who decided years ago that the door was closed. Aunt Linda is not just a person who plays cello. She's a person who proved to herself that she could still become someone new. That self-knowledge matters more than the cello.

Here's what I'd suggest if you've been holding back on something:

Pick one thing you've been putting off. Not five. One. The thing that comes to mind right now as you read this… that's probably the right one. Don't overthink the choice. The choice is much less important than the starting.

Set a small initial commitment. Not "I'm going to become fluent in French." Try "I'm going to do 15 minutes a day of language learning for 30 days." Small enough to actually do. Long enough to feel real. After 30 days, evaluate whether you want to continue. Often you will. Sometimes you won't. Either is fine.

Find a teacher early. The DIY approach is harder later in life because you have less time to recover from inefficient learning approaches. A few sessions with a teacher who can structure your initial practice will save months of fumbling.

Be patient with yourself in a way you maybe weren't with younger you. The progress will be slower than you remember. That's okay. The progress is still progress. Compounding still works. Six months from now, you'll be measurably better at the thing than you are today. A year from now, more so. Five years from now, you might be Aunt Linda in your own way.

Tell the right people. The people who will support you, not the people who will roll their eyes. Surround the project with belief. Defend it from the family member who will joke about your arms not being long enough for the cello. Some people in your life genuinely will not understand. That's their limitation, not yours.

Here's what I want you to take from all this. The brain you have right now is the youngest brain you'll ever have for the rest of your life. Whatever you're going to learn from here, you will learn it with this brain, today, or with a slightly older version of this brain, tomorrow. The window doesn't open later. The conditions don't get better. The only question is whether you start.

The "I'm too old" belief is probably the single most expensive lie people tell themselves. It costs them entire decades of growth, joy, expansion, and self-knowledge. It costs them the cello, the painting, the language, the new career, the chess mastery, the woodworking skill, the writing they've always wanted to try. It costs them friendships they would have made in those new pursuits. It costs them the version of themselves they could have become.

You don't have to pay this cost. The neuroscience doesn't make you. The research increasingly says the opposite… that learning new things later in life is one of the highest-leverage ways to actually maintain cognitive health. Aunt Linda isn't an exception. She's an example of what's available to you, if you'll let yourself believe it's available.

So the thing you've been putting off because you're "too old"… you're not. You weren't. You probably never were. Start. Today is a good day for it.

Even Bilbo started his adventure at 50, and Gandalf was thousands of years old when he was still learning new things about hobbits. Age was never the obstacle. The story was the obstacle.

Time to write a different one.

Keep learning (at any age),

Ray
