Science now tells us that the ageing mind does not simply decline. Some of its most valuable capacities continue to deepen.
By Dr. Leahcim Semaj
Transformational Psychologist
There is a peculiar stage of life in Jamaica when a person can become almost invisible to the labour market. You may be healthy. Your mind is still active. You have thirty or forty years of experience. You understand people, systems, customers, conflict and crisis. You have survived recessions, political changes, technological revolutions and more than one difficult boss.
You have made mistakes – and, more importantly, learned from them. But you are over 60. Suddenly, the experience that once made you valuable may now be used against you. You are told – sometimes directly, more often through silence – that you are overqualified, too expensive, unlikely to adapt or too close to retirement. Yet retirement may not be a realistic option. The pension is inadequate, if there is one at all. Savings must now stretch across another twenty or perhaps thirty years. The mortgage may be finished. Food, electricity, medication, insurance and home maintenance are not.
So here you are: Too experienced to hire. Too young to retire. This is not merely a personal problem for older Jamaicans. It is an extraordinary national waste. Worse, it is based on an outdated understanding of what happens to the human mind as we age.
Intelligence Does Not Simply Expire
For years, ageing was discussed as if the brain followed one steady path downward. You became older. You became slower. You became less useful. The science is now far more interesting than that. Psychologists distinguish between two broad forms of intelligence: fluid intelligence and crystallised intelligence.
Fluid intelligence is the ability to process unfamiliar information quickly, hold several new pieces of information in mind and solve a novel problem without depending heavily on previous knowledge. It is useful when learning a completely new system or reacting rapidly to an unfamiliar situation. Some aspects of fluid intelligence, especially speed of processing and certain forms of short-term memory, may decline with age. We should not pretend otherwise. But this is only one part of the human intelligence story.
Crystallised intelligence is the knowledge, vocabulary, judgement, pattern recognition and practical understanding accumulated through education and lived experience. It is what allows the experienced nurse to notice that something is wrong with a patient before the monitor sounds an alarm. It is what helps the veteran teacher recognise that a disruptive child may be distressed rather than simply “bad.” It is what enables the seasoned manager to hear a proposal, remember three similar attempts and quietly ask the one question everybody else overlooked.
Crystallised intelligence often remains stable much longer than many people assume. Some knowledge-based abilities may continue improving well into later adulthood. Research has also found that different cognitive abilities reach their strongest point at different stages of life; there is no single age at which the entire mind “peaks.” Some capacities mature relatively early, while vocabulary and other knowledge-based abilities may reach their highest levels decades later. (Hartshorne and Germine, Psychological Science)
In other words, an older brain may process some new information more slowly, but it may also understand what that information means more deeply. Speed is not the same as wisdom.
The Older Mind Has Seen the Movie Before
Crystallised intelligence is not merely the ability to remember facts. It allows us to recognise patterns. A younger employee may see an isolated event. An experienced employee may see the beginning of a familiar sequence. He has seen what happens when maintenance is postponed for too long. She remembers how a promising partnership collapsed because nobody clarified expectations. He has watched an organisation lose good employees after promoting a technically competent person who could not lead people.
This ability to connect the present situation with accumulated experience can shorten the distance between problem and solution. It may also prevent the organisation from making expensive mistakes. The experienced person has, in a sense, seen the movie before. The actors may be different, but the plot is familiar. That does not mean older workers are always right. Experience can become rigid. Someone may apply an old answer to a genuinely new problem. Crystallised intelligence is most valuable when it remains open to fresh information.
Still, Jamaica should not confuse rapid response with superior judgement. A person may answer quickly and be wrong. Another may pause, search decades of experience and recognise consequences that are invisible to everybody else in the room.
The Résumé Is Evidence, Not Baggage
Imagine a 62-year-old Jamaican who has spent decades in banking, hospitality, education, manufacturing, agriculture, telecommunications or public service. She understands the industry. She has managed staff, handled difficult customers, trained younger employees and solved problems that never appeared in any manual.
She applies for a job. The employer sees her résumé and begins asking silent questions: “Will she understand the technology?” “Will she take instructions from a younger manager?” “How long will she stay?” “Will she expect too much money?” These may appear to be reasonable concerns. Yet notice how often the older applicant is required to prove that age has not diminished her, while the younger applicant is allowed to represent possibility.
The younger person is hired for potential. The older person is rejected despite evidence. Even the expression “overqualified” deserves closer examination. Sometimes an employer genuinely fears that the applicant may become dissatisfied and leave.
But sometimes “overqualified” means: “You possess more experience than we know how to use.” Or, more uncomfortably: “Your knowledge may expose the limitations of the person supervising you.” What a strange national strategy – discarding competence because it comes with too much history.
When Jamaica Loses an Older Worker, It Loses a Library
Every time an experienced employee leaves without transferring what he or she knows, an organisation loses far more than a body occupying a position. It loses institutional memory. The procedures may be written down. The real knowledge usually is not.
Who remembers why that customer requires special handling? Who knows what caused a similar project to fail fifteen years ago? Who can identify the early signs of a labour dispute? Who knows which supplier delivers during a crisis and which one merely gives an impressive presentation? Who remembers the shortcut that saved the company millions – or the shortcut that nearly destroyed it? This is crystallised intelligence at work: not simply information, but information organised by experience. It lives inside people.
When experienced employees leave abruptly, younger workers are forced to learn, often at considerable cost, lessons the organisation has already paid for. We hold retirement functions. We present plaques. We eat curried goat and congratulate the person on “years of dedicated service.” Then the following Monday, we discover that nobody else knows how half the work was really done.
This Is Not Young Versus Old
The argument is not that older workers should occupy every position indefinitely. Young Jamaicans need opportunities. They bring energy, contemporary technical knowledge, fresh perspectives and the willingness to question practices that older workers may have accepted for too long. Older workers may bring judgement, professional networks, emotional steadiness, pattern recognition and a better sense of which organisational battles are worth fighting. We need both.
The younger employee may know how to operate the new technology. The older employee may understand the human system into which that technology must be introduced. The younger person may be faster at finding information. The older person may be better able to determine whether the information makes sense. The younger manager may see what could be. The older professional may remember why something similar did not work before. Put them together and the organisation becomes smarter. Separate them into competing generations and both lose.
Innovation without memory can become recklessness. Memory without innovation can become stagnation. The most productive workplace is likely to be one in which fluid and crystallised intelligence are deliberately combined.
Retirement Without Resources Is Not Leisure
There is another reality we do not discuss honestly enough. Many Jamaicans over 60 are not choosing between working and relaxing. They are choosing between working and financial insecurity. Not everybody has a pension. Not every pension keeps pace with the cost of living. Some people spent their most productive years supporting children, assisting relatives and building a family home. Others worked in the informal economy, where there was no structured retirement plan.
Then life intervenes. A spouse dies. A business fails. A medical condition consumes the savings. An adult child loses a job. A grandchild needs help with school fees. The money that looked adequate at 55 feels very different at 70. We speak romantically about retirement. We imagine travel, gardening and unhurried mornings. But retirement without sufficient resources is not leisure.
It is anxiety with more free time.
It may mean calculating whether the medication can last another week. It may mean avoiding social events because transportation costs money. It may mean becoming dependent on children who are already struggling—or who have migrated and are facing financial pressures of their own. Continued employment is not always about greed or an inability to “let go.” Sometimes it is about survival. Sometimes it is about dignity.
Work Is More Than a Paycheque
Work gives structure to life. There is somewhere to go, something to contribute and somebody who expects you to show up. Work can provide identity, social contact, mental stimulation and a sense of usefulness. Take that away abruptly and the psychological consequences can be serious.
The man whose opinion was sought every day may suddenly feel that nobody needs to hear from him. The woman who supervised an entire department may find that her life is now organised around errands and medical appointments. The phone rings less. The invitations stop. The world appears to move on without them.
Some people adjust beautifully. They deepen relationships, pursue neglected interests and enjoy freedom from organisational demands. Others struggle. The solution is not to keep everyone working forever. The issue is choice. Retirement should be a thoughtfully designed transition – not a compulsory disappearance.
Continued intellectual and occupational engagement may also help people maintain their skills. Recent longitudinal research suggests that age-related changes in literacy and numeracy are influenced not only by chronological age but by how frequently people continue using those abilities. “Use it or lose it” may be an oversimplification, but there is something important in it. (Hanushek and colleagues, 2024) A society that prevents older people from contributing may be helping to produce the very decline it uses to justify excluding them.
A New Architecture of Work After 60
Our traditional employment model offers two rigid options:
Fully employed or fully retired.
That model no longer fits the reality of longer lives.
An experienced manager may not want another five-day, high-pressure executive position. She may be willing to work three days each week, lead a special project or mentor newly appointed supervisors.
A retired teacher may not want responsibility for a full classroom but could coach younger teachers, support literacy programmes or work with students at risk of falling behind.
A skilled technician could train apprentices. A retired hotel executive could help a smaller property improve its service standards. A former public servant could assist with implementation instead of merely being invited to ceremonial functions.
We need more:
- Phased-retirement arrangements.
- Part-time and project-based positions.
- Formal mentoring roles with measurable outcomes.
- Skills-transfer programmes beginning several years before retirement.
- Returnships for older adults who wish to re-enter the workforce.
- Short-term consulting and advisory assignments.
- Digital-skills training delivered without condescension.
- Entrepreneurship support for people starting businesses after 60.
- Intergenerational teams designed to combine different cognitive strengths.
- Recruitment practices that measure competence rather than make assumptions based on age.
None of this requires charity.
The 60+ worker should not be hired because we feel sorry for older people. That would be insulting.
They should be considered because they may still be able to produce value—and, in some situations, a form of value that cannot be quickly taught or easily replaced.
Older Workers Must Also Remain Teachable
The responsibility does not rest only with employers.
Being experienced does not exempt anyone from learning.
An older worker who wants to remain economically relevant must be willing to update skills, use new technology, understand changing workplace cultures and sometimes report to someone younger.
Experience should produce confidence—but not arrogance.
Crystallised intelligence can become a trap when yesterday’s knowledge is treated as the only knowledge worth having.
The sentence “That is how we have always done it” is not proof of wisdom. Sometimes it is proof that learning has stopped.
We cannot demand that employers look beyond age while refusing to look beyond old methods.
The most valuable older workers are not those who believe they know everything.
They are those who know a great deal—and remain curious.
They can say, “I have never used this programme before. Show me.”
They can also say, “We tried something similar years ago. Let me explain what went wrong so that we do not repeat it.”
That combination—experience with openness—is powerful.
The 60+ Generation Is Also a Market
There is another contradiction.
Businesses often overlook people over 60 as workers and misunderstand them as consumers.
This generation purchases food, healthcare, insurance, travel, entertainment, technology, home improvements, financial services and professional care. Many continue supporting children and grandchildren. Some have fewer debts and greater purchasing power than younger adults.
Yet much of Jamaican marketing behaves as if meaningful life ends somewhere around 45.
The same society that does not know how to employ older people also does not know how to serve them.
That is not only ageism.
It is poor business.
Jamaica Needs a Longevity Strategy
We must stop discussing population ageing only as a pension and healthcare problem.
Longer life is also an economic, organisational and psychological opportunity.
What if Jamaica created a national registry of experienced professionals available for part-time work, mentoring, consulting and special projects?
What if companies received incentives for establishing structured intergenerational mentorship?
What if retirement preparation began at 45 rather than six months before the farewell function?
What if universities and training institutions offered short, practical programmes for people retooling at 55, 65 or 75?
What if government ministries, schools and businesses were required to capture critical institutional knowledge before experienced employees departed?
What if entrepreneurship programmes recognised that a 67-year-old may bring judgement, discipline and networks that a younger founder has not yet had time to develop?
We have spent decades educating, training and developing this generation.
Why would we discard the investment just when it has matured?
The Semaj MindSpa Takeaway
Ageing is not one long, uninterrupted intellectual decline.
Some mental processes may slow. Some kinds of memory may become less reliable. People must be assessed honestly and individually.
But the ageing mind may also possess something enormously valuable: a deep reservoir of accumulated knowledge, language, judgement, context and pattern recognition.
That is crystallised intelligence.
It is why the experienced doctor may reach a diagnosis after asking only a few well-chosen questions. It is why the veteran mechanic may hear a sound that means nothing to everybody else. It is why the seasoned leader may sense that a technically correct decision will fail because the people were not prepared for it.
These abilities do not appear overnight.
They are acquired through decades of study, work, failure, correction, observation and reflection.
Jamaica’s 60+ generation is not waiting to die. Many are waiting for another meaningful opportunity to contribute.
Some want full-time employment. Some want smaller roles. Some want to teach, mentor, consult or build something of their own. Others are ready to retire completely—and should be able to do so with dignity.
The future of work cannot belong exclusively to the young. Not in a society where people are living longer, pensions are uncertain and experience remains desperately needed.
To discard our older generation is like spending sixty years building a library—and then locking its doors just when the country needs its knowledge most.
They may not always think as quickly as they once did.
But they may understand more.
They are too experienced to be dismissed.
Too young to be written off.
And far too valuable for Jamaica to waste.
The Best Is Yet to Come.
