A short discussion exploring the ideas
She didn’t notice the damage until surgeons showed her the scans. Jo Cameron, a retired teacher from the Scottish Highlands, walked into a clinic in her mid-sixties expecting a routine answer about a nagging hip, and walked out with a very different story: years of severe joint degeneration that had unfolded almost entirely outside her awareness. She had given birth without pain relief, needed no medication after hand surgery most people describe as brutal, and only realized she had burned herself when she smelled her own skin. Friends and journalists were quick to call it a superpower. The team of pain geneticists who studied her were not so sure.
Their work eventually traced her unusual experience to a pair of rare genetic changes that turn down one of the body’s key pain pathways, leaving her with high levels of the so-called “bliss” chemicals that modulate discomfort and anxiety. On paper, that sounds enviable: less pain, less fear, faster healing. In practice, it meant living in a body that could be injured badly without her even knowing it, with no reliable early-warning system to demand attention. What looked from the outside like a gift was, up close, a reminder of what happens when one of the nervous system’s most basic maintenance signals goes missing.
Most people will never share Cameron’s experience, yet the way her story has been told matters for a different reason. It exposes how easily we misread pain itself. In a culture that treats discomfort as either something to conquer or something to fear, it is tempting to imagine that feeling less would always be an upgrade. For men in midlife, already carrying their own mix of aches, scans, and half-ignored warnings, Cameron’s case offers a different invitation. Instead of asking how to get rid of pain altogether, a more useful question begins to emerge: what if the real skill is learning how to read what pain is trying to say?

What Pain Is Actually Doing
If you only listened to the way people talk about it, you could be forgiven for thinking pain is a simple problem with a simple fix: a warning light you switch off once you’ve “handled” whatever caused it. The biology does not cooperate with that picture. Over the past few decades, pain science has moved away from the idea that pain is just a direct readout of tissue damage and toward a more demanding definition: pain as an experience the brain produces when enough evidence of possible threat is on the table. In 2020, the International Association for the Study of Pain updated its definition to make this explicit, describing pain as “an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage,” and emphasizing that you cannot infer pain just by watching nerves fire. The electrical signal travelling up a nerve is called nociception. The feeling that makes you pause, wince, guard, or change your plans is something else.
That distinction sounds technical, but it matters in daily life. Nociception is the body’s detection system, the flow of information along specialized nerve fibers that respond to heat, pressure, and chemical change. Pain is the brain’s verdict on that information in context. Two people can walk away from the same fall with very different experiences not because their tissues are radically different, but because their brains are evaluating what just happened through different lenses. The signals coming in from the body are part of the story, but they are not the whole story, and they are never read in isolation.
One useful way researchers describe this is the balance between what they call “Danger-In-Me” and “Safety-In-Me.” The brain is constantly weighing signals that imply danger: inflammation, fatigue, social isolation, recent scans, money stress, a story you tell yourself about what pain at this age must mean, against signals that imply safety: good sleep, movement you trust, supportive relationships, and a sense that someone competent is helping you make sense of what you feel. When the danger side of the ledger outweighs the safety side, pain becomes more likely. When safety signals are strong enough, pain can ease even when there is still tissue damage in the background. This is why the same arthritic knee can feel almost fine on a good day surrounded by people you enjoy and intensely painful on a lonely night after bad news, even though the joint itself has not changed dramatically in twelve hours.

Even in the simplest acute situations, pain is layered. When you touch something sharp or hot, the first flash of sensation that makes you pull away travels along really fast “A-delta” nerve fibers that carry a quick, sharp “first pain” lasting seconds. The heavier ache that follows travels along slower fibers called “C fibers” and can hang around much longer, nudging you to protect the area, rest, and pay attention. One phase is about getting you out of immediate trouble. The other is about changing your behaviour long enough for damaged tissue to repair. Both are part of a larger maintenance protocol the nervous system runs in the background, not just an annoyance attached to your day.
We’re in midlife, juggling work, family, and a body that does not always behave like it did at forty, this modern view of pain offers a more useful interpretation than “everything is just wearing out.” This view suggests that what you feel is not a simple, honest report of damage, but a composite signal: biology, yes, but also stress, sleep, mood, expectations, previous injuries, and the stories you have absorbed about what pain after fifty is supposed to mean. It does not trivialize serious problems or imply that pain is all in your head. Not at all. It does something more practical than that. It reframes pain as an integrated output, part sensory, part emotional, part behavioural, that your brain generates to protect you. The question then shifts from “How do I shut this off?” to “What is my system responding to, and which parts of that picture can I influence?”
When Pain Goes Missing: The Cost of Numbness
If Jo Cameron’s story tempts us to envy her, the broader history of people who cannot feel pain brings us back to earth. Congenital insensitivity to pain sounds like a comic-book origin story, but clinical descriptions are sobering: broken bones walked on until they deform, joints quietly destroyed over time, self-injury, and infections that progress because they never hurt enough to be noticed. In the most severe cases, children may lose vision, sustain irreversible joint damage, and, in some instances, die young, not from a single catastrophic event, but from the cumulative effects of injuries no one could feel. The absence of pain does not make them safer. It removes one of the body’s most reliable ways of insisting that something needs attention.

Seen that way, Cameron’s painless hip is not a quirky footnote. It is a case study in what happens when the volume of the signal we call pain is turned down too far. The system keeps taking loads, forces, and frictions it would normally ask you to redistribute or rest, and it does this in silence. On a scan, the story is obvious: cartilage worn, bone remodeling, structures slowly failing. In the lived day-to-day of someone who cannot feel those changes, life goes on as usual until the gap between appearance and reality becomes too large to ignore. The superpower frame starts to look less like freedom from suffering and more like a gentle caution: if you subtract pain entirely, you subtract one of the few ways your body can reliably get your attention before the consequences become too costly.
Most of us will never face that extreme. Our problem is more ordinary and, in its own way, trickier. We can feel pain, but we live in a culture that teaches us to treat it either as an enemy to be conquered or as a verdict to be feared. The result is that many men in midlife move through the world as if they are trying to approximate Cameron’s condition on purpose, numbing or overriding what they feel for as long as possible, or, at the other extreme, organizing their lives around avoiding any sensation that might hint at trouble. Her story, and the research around it, suggests a different option: not less pain at any cost, and not more stoicism, but a more precise relationship with the signal itself.
The Genome’s Lesson: We Mapped the Letters, Not the Language
In the same way we misunderstand pain, we often overestimate how much we understand the biology beneath it.
Part of what makes Cameron’s biology so revealing is where the key change sits. The mutation that drew scientists’ attention was not in a famous “pain gene” sitting in the protein-coding heart of the genome, but in a stretch of DNA once written off as junk. For years, large regions of noncoding DNA were treated as evolutionary leftovers. Her case helped overturn that assumption. The altered region turned out to participate in a subtle regulatory network that turns down a gene involved in breaking down the body’s own cannabinoids, small signaling molecules that help regulate pain, mood, and stress. When that network is nudged off balance, pain perception, mood, and wound healing all shift.
This is part of a much larger revision in how scientists think about the genome itself. The vast majority of our DNA does not code for proteins at all. Instead, it acts more like punctuation, spacing, and grammar: shaping when, where, and how strongly different genes are expressed. We have the alphabet figured out. We are still learning the language.

For men living in midlife bodies that feel more opinionated than they used to, this might sound far removed from everyday decisions. In practice, it offers a kind of interpretive humility that is worth carrying into the clinic and the gym. If a small change in an overlooked regulatory region can reshape pain, mood, and healing, then the systems we inhabit are clearly more layered than any simple story about “good” or “bad” sensations suggests. When a knee complains on stairs, or a back stiffens after a long drive, it is not just cartilage and muscle speaking. It is also a nervous system tuned by genetics, history, stress, sleep, and all the unseen regulatory machinery that decides how much emphasis any given signal should get. The point is not to make you suspicious of every ache, but to remind you that the body’s signaling system is sophisticated enough that quick, all-or-nothing interpretations rarely do it justice.
Midlife Men and the Two Common Failure Modes
Once you accept that pain is both a signal and an interpretation, another pattern starts to show up in midlife: not so much in the biology, but in how men respond. One failure mode is dismissal. Pain is folded into a familiar story about aging, work, or toughness and pushed into the background for as long as possible. Culturally, this kind of stoicism is often praised.
The second failure mode is catastrophizing. Here, the problem is not that pain is ignored, but that it is granted too much authority over the rest of life. Pain catastrophizing is characterized by rumination, magnification, and helplessness, and it has been linked to worse disability, poorer treatment responsiveness, and reduced function. Over time, this pattern can lead to more disability than the original injury ever warranted and can make even helpful treatments less effective, because every flare is interpreted as failure rather than part of a normal adaptation process.
Most men know both tendencies, sometimes in different domains. You might shrug off knee pain as “nothing” while quietly fearing that any twinge in your chest is a prelude to catastrophe, or dismiss chronic neck pain from desk work while avoiding strength training because you are convinced it is too risky “at this age.” The common thread is that in both dismissal and catastrophizing, pain stops operating as a nuanced signal and becomes either background noise or an alarm that never switches off. In neither case is the signal actually being read.
Pain Literacy: Learning to Read the Signal
Between those two extremes lies a third option: treating pain less like a moral test and more like a literacy problem. Pain literacy is not about developing a higher tolerance or bragging rights about what you can endure. It is the skill of asking, when something hurts, “What is this likely to be?” and “What is this asking me to adjust?” rather than defaulting to “nothing” or “everything”.

It also means paying attention to how context shapes what you feel. The clinical framework distinguishes different types of pain, and not all of them signal the same thing or call for the same response. None of these questions turn you into your own doctor, but they do move you from being a passive recipient of sensations to an active interpreter. They make medical visits more productive because you can describe patterns rather than just intensity, and they make self-care decisions more grounded because you are basing them on how the signal behaves, not just how loudly it speaks in one moment.
For many men, developing this literacy is less about memorizing anatomy and more about unlearning old rules. “No pain, no gain” and “never complain” are poor guides in midlife. So is the idea that any pain automatically means “stop everything.” A more accurate set of defaults might sound like this: new, severe, or unexplained pain deserves timely attention; persistent pain that limits life is worth investigating even if you can still push through it; familiar, low-grade pain that settles with reasonable adjustment is often a sign to recalibrate rather than to retreat. The body will still surprise you, but you are no longer flying blind. You are treating pain as information and yourself as someone capable of learning its basic grammar.
How To Work With Pain, Not Against It
You do not need to become a pain expert to change how you respond. A few simple habits can shift you out of ignoring it or fearing it, and into working with it.
1. Upgrade your questions: The next time something hurts, instead of asking how bad it is, try asking when it shows up, when it eases, whether gentle movement changes it, and whether sleep, stress, or training have shifted recently. This kind of pattern-tracking supports better symptom interpretation and more useful clinical conversations.
2. Use a simple traffic-light rule: Most day-to-day pain is easier to manage when you stop sorting it into only nothing or emergency. Mild, familiar discomfort that warms up and settles can often be monitored, while pain that is new, sharper, more persistent, or function-limiting is a cue to reduce load or seek care sooner rather than later. This approach fits the broader pain-literacy goal of matching your response to the kind of signal you are receiving rather than reacting from habit alone.
3. Make small, testable adjustments: When pain is not clearly dangerous, small changes often teach you more than either grinding through it or stopping everything. Reducing load, range, or frequency for a short period, and changing one variable at a time, allows you to observe whether symptoms settle or spread. That kind of structured adjustment is consistent with biopsychosocial care and with the evidence that pain-related fear and catastrophizing improve when people regain a sense of workable control.
4. Set a time limit on waiting it out: Stoic delay is one of the easiest traps to fall into, especially for men who are used to functioning through discomfort. For familiar, low-grade pain that behaves in predictable ways, giving yourself a simple rule such as “if this is still limiting me in four weeks, I will talk to someone about it” reduces the odds that a manageable issue quietly becomes a bigger one. New, severe, or unexplained symptoms, especially those involving the chest, breathing, or neurological changes, operate by a different set of rules and warrant much earlier attention.
5. Bring a better story to the appointment: When you do speak with a clinician, a short timeline, a few observed patterns, and one clear question are often more useful than a pain score alone. When did it start, what makes it better or worse, how has it changed over time, and what does it limit you from doing are all details that help turn a vague complaint into something interpretable. Pain care improves when the signal is described in context rather than as an isolated number, because decisions are rarely based on pain intensity alone, but on how the pattern behaves. Bringing that kind of structure into the conversation makes it easier for both of you to see what is most likely going on and what to do next.
6. Keep one movement that means you are still in the game: If pain has shrunk your world, hold onto one realistic form of movement you can tolerate most days. It does not need to be heroic. It just needs to be repeatable. This supports function, reduces fear-driven retreat, and helps keep pain from becoming the sole organizer of daily life.

Turning Signals into Stewardship
If there is a common thread running from Jo Cameron’s silent hip through the genome’s regulatory complexity to the everyday back, shoulder, or knee that complicates a midlife day, it is that pain is not a simple villain or a simple verdict. It is one of the ways a complex system tries to keep itself intact in a world that asks more of it than it did at thirty. For men in the second half of life, that is not a reason to tolerate unnecessary suffering or to admire those who ignore their bodies the longest. It is an invitation to a different kind of relationship with discomfort, one that treats pain neither as a badge of honour nor as a prophecy, but as a message that deserves to be read with some care.
Stewardship is a helpful word here. You cannot control every signal your body sends, but you can decide how you respond when a pattern keeps showing up. You can choose to notice earlier rather than later, to seek clarification before you are forced to, to adjust load, sleep, and stress when a familiar area starts complaining more loudly, and to ask for help without waiting until the situation is dramatic enough to justify it. None of this turns midlife into a pain-free territory. What it does offer is a way to stay in relationship with your body that is more collaborative than adversarial.
In that sense, the real superpower is not feeling less. It is being willing to listen more closely, to update old stories about what pain means, and to let those updates shape how you move, train, rest, and seek care. The signals will keep coming. Pain, in one form or another, is part of being alive in a body that changes over time. The question is whether you will treat those signals as random noise, as threats to brace against, or as part of a conversation you are having.
Health after 50 is rarely shaped by any single factor.
It emerges from how multiple systems interact and adapt over time, often in ways that aren’t obvious when viewed in isolation.
