A few months after I retired, I had a moment that took me completely by surprise.
I had spent years looking forward to having more freedom. I had held senior leadership positions, managed large teams and carried the sort of responsibility that does not always disappear when you close the office door. Retirement was supposed to mean relief: no meetings, no deadlines, no difficult decisions and no problems arriving in my inbox before I had finished my morning coffee.
And initially, that freedom felt wonderful.
But once the novelty wore off, I began to feel strangely unmoored. I did not want my old job back, but I was starting to understand how much it had quietly been giving me.
My work had organised my time. It had required me to think, plan, learn, negotiate and solve problems. Other people expected me to turn up. Decisions depended on me. Even on days when I did not feel particularly motivated, the structure of work pulled me into the world.
When that disappeared, I was left with a question that our traditional approach to retirement planning rarely asks:
What was going to replace it?
We don’t only retire from a job
Most conversations about retirement focus on what we are leaving behind.
We talk about leaving the commute, the pressure, the office politics and the alarm clock. We calculate whether we have enough money and imagine what we will do with all those gloriously empty hours.
But retirement also removes things we may not realise we need until they are gone.
Work often provides challenge, identity, social contact, routine, recognition and a sense of contribution. It makes us use memory, judgement and problem-solving skills. It asks us to adapt when plans change and deal with people whose opinions are not always the same as ours.
This helps explain why retirement can feel liberating and unsettling at the same time. We may be delighted to escape the pressure while still missing the structure. We may not miss the job itself but miss being competent, useful and part of something.
That distinction matters.
Retirement itself is not the enemy
A 2025 review examining 22 studies explored the relationship between retirement and cognitive functioning. Most of the studies identified either a negative association or no clear effect, while a smaller number found positive outcomes.
This does not mean retirement inevitably causes cognitive decline, and it certainly does not mean we should cling to our jobs out of fear.
Retirement can be enormously beneficial, particularly for someone leaving physically exhausting, highly stressful or unhealthy work. More time for sleep, exercise, relationships and medical care can improve both physical and emotional wellbeing.
The brain remains capable of learning and adapting throughout life, but it responds to what we repeatedly ask it to do. If work was our main source of challenge, social contact and complex problem-solving, removing it can create a sudden drop in stimulation.
The answer is not to recreate the stress of our working years. It is to make sure freedom does not quietly turn into withdrawal.
A full calendar is not necessarily a fulfilling life
When people worry about retirement, they are often advised to “keep busy.”
I understand the intention, but I do not think being busy is enough.
It is possible to fill an entire week without doing anything that stretches us, connects us deeply or gives us a sense of progress. Errands, television, housework and occasional lunches can occupy plenty of time. They may even be enjoyable. But activity and engagement are not quite the same thing.
A better question might be:
What in my life is still asking something of me?
Perhaps you are learning a language and have reached the awkward stage where your brain insists it knows the word but refuses to produce it. Perhaps you have joined a community organisation that needs your experience. You might be learning to paint, mentoring a younger person, planning an unfamiliar journey or trying strength training for the first time.
The challenge does not need to be grand or impressive. It simply needs to take you slightly beyond what is already comfortable and automatic.
There is a valuable middle ground between relentless productivity and complete passivity. We do not need to spend retirement proving our usefulness, but most of us still need opportunities to grow, contribute and feel involved.
Knowing what is good for us is not the same as doing it
Australian researchers recently demonstrated how important this distinction can be.
The Maintain Your Brain trial, led by Professor Henry Brodaty and colleagues, recruited more than 6,000 Australians aged between 55 and 77 who had at least two modifiable risk factors for dementia.
The control group received publicly available health information. The intervention group received personalised online coaching in areas relevant to their individual risks, including physical activity, nutrition, cognitive training and support for depression or anxiety.
After three years, the personalised intervention group achieved significantly better overall cognitive results, measured through tests of memory, reasoning and processing speed.
The study did not prove that the program prevented dementia. However, it provided encouraging evidence that a personalised, multidimensional approach can support cognitive health.
Most of us already know the broad advice. Move our bodies. Eat well. Keep learning. Look after our emotional health. Stay connected.
Information is rarely the whole problem. The problem is translating “I should” into something that repeatedly happens in real life.
Structure turns a good intention into a real life
The 2025 US POINTER trial reached a related conclusion.
The trial involved 2,111 adults aged 60 to 79 who were at increased risk of cognitive decline. Both groups were encouraged to improve their physical activity, nutrition, cognitive challenge, social engagement and cardiovascular health.
However, one group followed a more structured and intensive program with regular meetings, prescribed activities and greater accountability. The other received a lower-intensity, self-guided program.
Cognitive scores improved in both groups, although some of that improvement may have resulted from becoming familiar with the tests. Importantly, the structured group experienced a modest but statistically greater improvement in overall cognition. The researchers emphasised that more investigation is needed to understand the long-term clinical significance.
For me, the most useful message is not that everyone needs a highly organised retirement program. It is that intentions become more powerful when they are supported by structure.
Your retirement vision needs an ordinary Wednesday
When we imagine retirement, our minds naturally jump to the highlights. We see holidays, family celebrations, long lunches and places we have always wanted to visit.
Those experiences matter. I am a great believer in dreaming big and having adventures to look forward to.
But most of retirement is not lived on a river cruise through Europe. It is lived on an ordinary Wednesday.
That is why one of the most revealing retirement exercises is to imagine a normal weekday two or three years from now.
Where are you living? What gets you out of bed? How do you move your body? Who will you speak to? Is there somewhere you are expected to be? What are you learning or creating? What are you working towards? What gives shape to the day?
I believe a thriving retirement needs four broad ingredients: health and vitality, meaningful connection and growth, a sense of purpose, and room to dream big.
An ordinary Wednesday does not need to contain all four in equal measure. But over the course of a week, each ingredient should have somewhere to live.
Without energy, it becomes harder to participate in life. Without connection, freedom can become loneliness. Without purpose, days can lose their shape. Without dreams and growth, life can begin to shrink around what is already familiar.
Retirement is allowed to be restful
None of this means every hour needs to be productive.
Retirement should include slow mornings, spontaneous trips, afternoon reading, time with family and days when absolutely nothing useful is achieved. Rest is not something we need to earn repeatedly by staying busy.
The goal is not to replace one demanding schedule with another. It is to create enough chosen structure to support the life we want.
That was one of the most important lessons of my own transition. I did not need my old role back. I needed to understand what the role had provided and find new, more intentional ways of meeting those needs.
Retirement is not simply freedom from work. It is freedom to decide what will challenge us, where we will contribute, who we will share our lives with and what we still want to become.
We can leave behind the deadlines, meetings and office politics without leaving behind curiosity, growth and the feeling that our presence matters.
Perhaps that is the retirement vision worth creating: not a life permanently on holiday, but a life we still feel fully part of.
