Reading the Evidence Honestly: Conditions for a Flourishing Early Retirement

Introduction

The ten chapters before this one have explored the many ways early retirement can enrich a life: better health, deeper rest, time freedom, family, friendship, purpose, learning, travel, creativity and reinvention. Those benefits are real, and the stories behind them are inspiring. But a book that only told good news would not deserve your trust.

The honest truth is that retirement is not one experience but many. For some people, leaving work early is the best decision they ever made. For others, it brings loneliness, drift or a sudden loss of identity. For a few, especially those pushed out rather than choosing to go, it can be harmful.

Our question is practical: under what conditions does early retirement go well, and under what conditions does it go badly? The answer turns out to be encouraging, because many of the conditions that matter most are ones you can influence.

What the research tells us

Retirement is not one experience

One of the most important lessons from recent research is that averages hide a great deal. Mo Wang, using two samples (994 and 1,066 retirees) from the US Health and Retirement Study, found three distinct patterns of change in psychological wellbeing coexisting among retirees, and concluded that retirees “do not follow a uniform adjustment pattern” (Wang, 2007). Different subgroups were linked to factors such as whether they took a bridge job and whether their spouse was still working (Wang, 2007).

A German study of 1,456 retirees reached a similar conclusion. Martin Pinquart and Ines Schindler identified three groups: one whose life satisfaction dipped at retirement but then stabilised or rose; one whose satisfaction jumped at retirement but then declined overall; and one who experienced only a very small temporary increase (Pinquart and Schindler, 2007). The groups differed by retirement age, gender, socioeconomic status, marital status, health and whether people had been unemployed before retiring, and the authors observed that “resource-rich individuals are less likely to experience retirement-related change in satisfaction” (Pinquart and Schindler, 2007).

This helps explain why headlines about retirement can seem contradictory. The more useful question is not “is retirement good for people?” but “for whom, and under what conditions?”

A wide review of this field by Wang, Henkens and van Solinge (2011) proposed exactly this kind of resource-based perspective: how well people adjust depends on the resources they have and how those resources change over time.

Condition 1: choice

If there is one finding that runs through the research more consistently than any other, it is that retirement goes better when it is chosen.

A Dutch study of 778 employees, followed across the transition, found that adjustment problems arose partly from “a lack of control over the decision” (van Solinge and Henkens, 2008). A study that followed 117 male retirees found that voluntary retirement status, along with physical health and income, predicted short-term adjustment (Gall, Evans and Howard, 1997). And, as the Introduction noted, a US study found that what shaped the change in happiness on retiring was not whether people phased out gradually or stopped abruptly, but whether they perceived the transition “as chosen or forced” (Calvo, Haverstick and Sass, 2009).

A white paper for the Society for Industrial and Organizational Psychology, summarising some twenty years of research, reached the same conclusion: retirees who perceive their decision as voluntary, and who have prepared for retirement, are more likely to enjoy better psychological wellbeing, while those who retire earlier than they expected or planned are more likely to struggle (Wang and Hesketh, 2012). The authors singled out people with no control over the timing of retirement as particularly at risk (Wang and Hesketh, 2012).

Choice also appears in studies of physical health. A meta-analysis of 85 studies published between 2000 and 2021 found that, overall, the effect of retirement on health outcomes was very small, but that “mandatory or involuntary retirement is associated with a negative impact of retirement on health, although it is small in magnitude” (Filomena and Picchio, 2023). A European study using data from the Survey of Health, Ageing and Retirement in Europe (SHARE) found that retiring for aspirational reasons or in positive circumstances was associated with lower depression, while retiring under negative circumstances was associated with worse mental health (Vo and Phu-Duyen, 2023).

The implication is powerful. Much of what the gloomier studies report belongs to involuntary retirement. Early retirement as this book describes it, a planned and chosen step, starts from the more favourable side of that divide.

Condition 2: patience through the phases

In 1976 the American gerontologist Robert Atchley published The Sociology of Retirement, which described retirement not as a single event but as a process unfolding through phases (Atchley, 1976). One recent study summarises the model as six stages: pre-retirement, retirement, disenchantment, reorientation, retirement routine and termination of retirement (Vo and Phu-Duyen, 2023). The early period of retirement is often described as a “honeymoon” of enjoying new freedom, while disenchantment is the phase in which people meet the reality of everyday retired life and may feel let down (Vo and Phu-Duyen, 2023). Atchley’s phases are a descriptive framework rather than a fixed timetable: not everyone passes through every phase, or in the same order.

Some empirical work fits this picture. Gall, Evans and Howard (1997) followed their retirees from a few months before retirement to six or seven years after, and found increases in wellbeing during the first year, with evidence of a continuing adjustment process afterwards. Vo and Phu-Duyen (2023) found that the mental health benefits of retirement in their European data appeared before and around retirement but were no longer evident two years later, “when the ‘honeymoon’ phase was over”.

The lesson is not that the joy of freedom is an illusion, but that it can change shape. The early months may feel like an endless holiday; later, the question of what to do with the freedom becomes more pressing. Knowing that a flatter period may come can make it easier to weather. The reorientation phase is often where the most rewarding choices are made: the volunteering role, the course, the new friendships, the creative project.

Condition 3: an identity beyond the job

For many people work is more than a source of income. It supplies structure, status, colleagues and a ready answer to the question “What do you do?” Leaving it can mean losing part of one’s sense of self.

The research supports this concern. The SIOP white paper notes that retirees who strongly identify with their work roles are often more likely to experience decreases in psychological wellbeing when entering retirement (Wang and Hesketh, 2012). The Dutch study found that adjustment problems arose partly from pre-retirement anxiety about the social consequences of retirement, and described the transition as involving two challenges: adjusting to the loss of the work role and its social ties, and developing a satisfying post-retirement lifestyle (van Solinge and Henkens, 2008).

Social psychologists working on the “social identity model of identity change” argue that adjustment to retirement is enhanced when people can keep valued group memberships and develop meaningful new ones (Haslam et al., 2019). A striking study from England supports this. Using the English Longitudinal Study of Ageing, Steffens et al. (2016) compared 424 people who retired with a matched group who did not. Among retirees who had belonged to two groups before retirement, the risk of death in the first six years was 2% if they kept both memberships, 5% if they lost one and 12% if they lost both. The authors noted that the effect of group memberships on mortality was comparable to that of physical exercise (Steffens et al., 2016). As an observational study it cannot prove cause and effect, but the message is clear: identities and belonging built outside work are protective.

This is why Chapters 5 (Friendship and community) and 6 (Purpose and giving back) matter so much: they may be among the most important foundations of a good early retirement.

Condition 4: keep the mind engaged

Perhaps the most widely reported worry about early retirement concerns the brain. In a well-known paper titled “Mental retirement”, Susann Rohwedder and Robert Willis used comparable survey data from the United States, England and continental Europe, and exploited differences in national pension, tax and disability policies, to argue that early retirement has a significant, causal negative effect on the cognitive ability of people in their early sixties (Rohwedder and Willis, 2010).

A UK study adds detail. Following 3,433 civil servants in the Whitehall II study for up to 14 years either side of retirement, Xue et al. (2018) found that verbal memory declined 38% faster after retirement than before, after taking account of age-related decline, although retirement had no significant effect on the other cognitive domains measured (abstract reasoning and two types of verbal fluency). The authors framed their work around the “use it or lose it” hypothesis, and concluded that the findings point to the value of the cognitively stimulating activities that employment often provides (Xue et al., 2018).

Yet the picture is genuinely mixed. Using offers of early retirement windows in the US Health and Retirement Study, Coe et al. (2012) found no clear relationship between retirement duration and later-life cognition for white-collar workers and, if anything, a positive relationship for blue-collar workers. Using SHARE data, Celidoni, Dal Bianco and Weber (2017) found that retirement had a long-term detrimental effect on cognition for people who retired at the statutory eligibility age, but a protective role for those who retired on an early retirement scheme. An English study using a regression discontinuity design around pension age found no evidence of changes to cognitive ability at retirement (Rose, 2020).

A plausible and hopeful reading is that it is not retirement itself that dulls the mind, but the loss of mental challenge that can accompany it. Work is only one source of stimulation; learning, community projects, writing, music or a small business can all keep the mind busy. Chapters 7 and 9 are, in this light, partly about protecting cognitive health.

Condition 5: good health habits, and a sober view of mortality studies

Does retiring early help you live longer, or shorten your life? Here, too, the evidence is mixed, and it is worth being candid.

Some studies find harm. Fitzpatrick and Moore (2018), using mortality data for the whole US population, documented a 2% increase in male mortality immediately after age 62, the age of eligibility for Social Security, and linked it to retirement and associated lifestyle changes; the change for women was smaller and imprecisely estimated. In Austria, Kuhn et al. (2020) exploited a policy that let workers in some regions leave the labour force earlier, and estimated that for men, retiring one year earlier increased the risk of premature death by 6.8%, with no significant effect for women. A US study of former Shell Oil employees found that those who retired at 55 and survived to 65 had higher mortality than those who retired at 65 (Tsai et al., 2005). Studies of this last kind face a well-known difficulty: people in poorer health may be more likely to retire early, making it hard to separate cause from effect.

Other studies find no effect. Using data on the entire Norwegian population and a series of policy changes that lowered the retirement age for some workers, Hernaes et al. (2013) found no effect of retirement age on mortality. In England, Rose (2020) found that retirement “substantially improves well-being and reported health”, with no evidence of changes in mortality. And the meta-analysis of 85 studies found that retirement’s overall effect on health was very small, with involuntary retirement the clearest source of harm (Filomena and Picchio, 2023).

How should we read this? Many of the studies showing harm concern people whose retirement was triggered by policy or eligibility rules rather than personal readiness, and effects were clearer for men than for women. And what people do after retiring plausibly matters a great deal. Fitzpatrick and Moore (2018) pointed specifically to lifestyle changes. A US study of 12,189 retirees found that bridge employment was associated with fewer major diseases and functional limitations than full retirement (Zhan et al., 2009). And the English evidence on group memberships suggests that staying socially connected may protect life itself (Steffens et al., 2016).

Condition 6: financial security as a foundation

None of the benefits in this book is easy to enjoy while worrying about money. The research is consistent that financial resources underpin a good retirement. The Dutch study found that retirement satisfaction was primarily related to access to three key resources: “finances, health, and the marital relationship” (van Solinge and Henkens, 2008). Income predicted short-term adjustment in Gall, Evans and Howard’s (1997) study, socioeconomic status distinguished the different German trajectories (Pinquart and Schindler, 2007), and the SIOP review lists financial status among the factors repeatedly associated with better psychological wellbeing (Wang and Hesketh, 2012).

For early retirees the financial challenge is sharper, because savings must last longer. As the Introduction explained, the famous “4% rule” was derived for retirements of about 30 years using US market history, and the Trinity study authors cautioned that “early retirees who anticipate long payout periods should plan on lower withdrawal rates” (Cooley, Hubbard and Walz, 1998, p. 21). Financial security does not require great wealth; many of the pioneers of the early retirement movement lived very frugally. But it does require a realistic plan, a margin for error and, ideally, independent professional advice. (This book, again, is not financial advice.)

Condition 7: retire to something

The final condition may be the most important, and it draws the others together. Early retirement flourishes when people retire to something, not merely from something.

The SIOP review found that people who retire to engage in leisure or other non-work activities are more likely to experience better psychological wellbeing, whereas those who retire for health reasons are more likely to see it decline (Wang and Hesketh, 2012). It also found that bridge employment, volunteering and leisure activities are all beneficial, and that retirees who work for generative reasons, such as teaching and sharing knowledge with younger generations, are more likely to experience improved wellbeing (Wang and Hesketh, 2012). The European evidence that retiring for “aspirational” reasons is associated with lower depression points the same way (Vo and Phu-Duyen, 2023).

This is also what the pioneers of early retirement say from experience, as the stories below show.

Lives enriched: real stories

Jacob Lund Fisker — meaning over fun

Jacob Lund Fisker, whose Early Retirement Extreme blog helped to launch the modern movement, reflected on a decade of freedom in 2019. He noted that the first years of any retirement are often filled with things there was never time for while working, and for him that meant sport. But his longer-term prescription for a successful job-free life was to find activities that combine “meaning+fun and theoretical+practical”, adding that “in the long run, meaning is more important than fun” (Fisker, 2019). He was also candid about the risk of a purely leisure-based early retirement, observing that “it’s not uncommon that young FIRE people eventually get bored and go back to their old jobs” (Fisker, 2019). His own answer was to focus on adding value, which he found created plenty of experiences to pursue.

Pete Adeney — the freedom to work

Pete Adeney, who writes as Mr Money Mustache, left full-time work in 2005 at the age of 30 (Bortz, 2024). Replying to a reader on his first blog post, he suggested that one way to protect an early retirement against poor markets was “leaving the door open to more work in the future if you need it”, adding: “I like to feel empowered by working occasionally even if I don’t need the money” (Adeney, 2011). For Adeney, early retirement did not mean never working again. It meant working only on his own terms, and spending most of his time on what mattered most to him, which, he told AARP, was raising his son (Bortz, 2024).

A balanced view

Reading the evidence honestly means acknowledging its limits.

• Much of the research concerns retirement at conventional ages. Studies of people leaving work at 60 to 65 may not describe the experience of someone who retires at 45, whose friends are still working and whose financial horizon is much longer.
• Cause and effect are hard to untangle. People who retire early differ from those who do not in health, wealth, personality and occupation. The best studies use policy changes or eligibility rules to get closer to causal effects, but these often capture people nudged into retirement rather than those choosing it freely, which is exactly the group this book is most concerned with.
• Findings vary by country and group. Pension systems, cultures and labour markets differ, and results for men and women sometimes diverge.
• Averages hide diversity. As the trajectory studies show, some people thrive, some struggle and some barely change. No single study can tell you which group you will be in.

What emerges is not a verdict for or against early retirement, but a map of the conditions that tend to make it go well.

Putting it into practice

Drawing the evidence together, you might ask yourself these questions before, and during, your own freedom years.

1. Is this my choice? If you have some control over timing, use it. If retirement is being forced on you, recognise that it may be harder, and seek support early.
2. Am I financially secure for the long haul? Build a realistic plan for a potentially long retirement, with a margin for error, and take regulated professional advice.
3. What am I retiring to? Name two or three things (a cause, a craft, a course, a community) that you are moving towards.
4. Where will I belong? Keep up the friendships and groups you value, and deliberately join at least one new group in your first year.
5. How will I keep my mind stretched? Plan for challenge as well as comfort: learning, problem-solving, teaching or creative work.
6. How will I look after my body? Use your new time to build habits of movement, sleep and good food.
7. Can I be patient with the phases? Expect a honeymoon, and do not be alarmed if a flatter period follows. Treat it as the moment to reorient, not a sign of failure.
8. Will I leave a door open? Consider whether some paid or voluntary work, on your own terms, might add structure, purpose and security.

Questions for reflection

• When you imagine your early retirement, how much of the picture is about escaping work, and how much about moving towards something?
• Which of your current friendships and group memberships depend on your job? How might you nurture them, or build new ones, if you left?
• Which parts of your identity would remain if nobody asked, “What do you do?”
• What activities in your life today leave you mentally stretched, and could any of them grow into something larger?
• If a period of restlessness came after the honeymoon, what would you want to turn towards?

Conclusion — Your Freedom Years

We began this book with an ordinary Tuesday: a day with nowhere you must be. We end it knowing a little more about how to make such days good.

The research does not promise that early retirement will transform every life. It shows something more useful: that the outcome is not left to chance. The people who flourish in their freedom years tend to be those who chose to be there; who have enough financial security to stop worrying; who stay connected to others and build new communities; who keep learning and creating; who look after their bodies; and, above all, who retire to something that gives their days meaning. Nearly every one of those conditions is, at least in part, within your influence.

Seen this way, the ten benefits in this book are not simply rewards that early retirement hands out. They are also the practices that make it work. Moving your body protects your health. Family and friendship guard against isolation. Learning and creativity keep your mind alive. Purpose replaces what work once supplied, and often exceeds it. And time freedom, the heart of it all, makes every other choice possible.

We are living longer than any generation before us. The Office for National Statistics projects that people aged 65 in 2023 will live, on average, around two more decades (Office for National Statistics, 2025). That is a whole season of life: long enough to master a skill, build a community, launch a venture, see grandchildren grow, or give something lasting to the world. How you spend it is one of the most important decisions you will make.

This book will keep growing as new research appears and new stories are told. Perhaps, one day, yours will be among them.

Your freedom years are waiting. Make them yours.
