The Longevity Imperative

the average human lifespan has increased significantly in recent decades and continues to rise. this provides us with more time to explore our ambitions, build meaningful connections, and redefine how we approach each stage of life. these additional years bring immense potential but also challenge us to ensure that this extended time is spent in ways that are healthy, productive, and fulfilling.

to respond to this shift, we need to move beyond outdated views that frame longevity as a burden on society. instead, a longevity society envisions transforming health care, education, and economic systems to support longer lives and create opportunities for all generations. at its core is the idea of an evergreen agenda – a commitment to remaining engaged and purposeful throughout life’s extended course. by embracing these changes, individuals and communities alike can thrive in an era defined by longer lifespans.

in this chapter, you’ll discover practical ways to make the most of a longer life. from strategies for healthy aging and financial security to overcoming age-related challenges, you’ll learn how to maintain purpose and productivity, adapt to a changing workplace, and plan for a fulfilling future. along the way, you’ll see how individuals and societies alike can embrace the opportunities that come with extended lifespans.

longevity isn’t just living longer – it’s living better. by rethinking aging and preparing for a new era of life expectancy, you can turn your extra years into your most meaningful ones. 

life expectancy has risen dramatically, shifting from an era of high infant mortality to one where longer lives are the norm. this trend means that younger generations can expect to live into their 80s, or even 90s. with this extended lifespan, it's essential to rethink how we plan for the future – not just in terms of old age, but throughout all stages of life. this includes taking proactive steps to stay healthy, financially secure, and emotionally fulfilled.

as we grow older, concerns about health, loneliness, and irrelevance are common. these fears highlight the importance of addressing physical and mental well-being early on. the good news is, aging doesn’t have to mean inevitable decline. by making smart choices, such as prioritizing diet, staying active, and fostering meaningful relationships, many age-related health issues can be delayed or prevented. aging itself is not a fixed process – it’s malleable. the habits and choices you make in earlier life, including your education, health practices, and social connections, will significantly impact your later years.

rather than seeing an aging population as a burden, it’s more productive to view it as a “longevity society” where people of all ages remain vibrant and continue to contribute. this shift, however, requires planning ahead. focus on maintaining health, securing finances, and finding purpose – all while being aware that living longer – demands we adapt our life strategies. the earlier we start, the better equipped we’ll be to enjoy a fulfilling life, no matter how many years it brings.

aging presents challenges, like frailty, but we don’t have to passively accept these. healthy habits – such as nutritious eating, regular exercise, and maintaining social bonds – are key in minimizing age-related issues. the goal should be to live healthily as long as possible and to compress the period of frailty toward the end of life. preventative care and staying active are essential in this process. for this vision to become a reality, society must invest in systems that promote healthy lifestyles for everyone, not just the privileged few. in doing so, we can truly make the most of the longer lives we’re now able to live.

what does aging ‘well’ mean? it’s not just a matter of living longer, but staying healthy throughout life. the concept of healthspan – the years spent in good health – should be prioritized over lifespan, which only tracks how many years we live. aging better means focusing on quality, not just quantity, of life.

to illustrate different ways aging could unfold, let’s look at four fictional characters. jonathan swift’s struldbruggs are immortal but suffer from poor health, showing that living forever isn’t worth much if you don’t have quality health. contrasting them with oscar wilde’s dorian gray – who maintains his health but doesn’t try to live forever – suggests that a healthy life, even if shorter, is preferable to ill-health in later life. j. m. barrie’s peter pan offers an example of slowing down aging itself, both improving health and extending life whereas marvel comics’s wolverine, with his ability to reverse aging and regain his youthful state, brings in the idea of regenerative medicine, which could one day help us restore health and vitality.

in real life, governments should focus on extending the years people live in good health, rather than simply increasing the number of years they live. a major part of aging better involves shifting the focus from treating diseases to preventing aging itself. this could be achieved through the lifestyle changes we’ve already mentioned – like regular exercise, a balanced diet, and mental engagement – as well as medical advancements. the economic benefits of investing in healthier aging are significant, too. longer, healthier lives mean reduced healthcare costs, less spending on disease treatment, and more productive citizens, which could even lead to a boost in gdp.

advances in science, particularly in the field of geroscience – the science of health and aging – offer hope for breakthrough treatments like senolytic drugs and stem cell therapies. additionally, technologies like genetic testing and biomarkers can help us predict age-related risks earlier, allowing for early interventions. menopause, especially for women, should also be considered in the broader conversation about aging, as it plays a major role in long-term health.

although we’re not there yet, the future holds potential for significant improvements in how we age, and focusing on prevention today will lay the foundation for a healthier tomorrow.

longer life expectancy brings significant economic challenges, particularly as people live longer, work more years, and face rising costs for retirement and health care. when considering how to deal with these challenges, there are two main strategies: saving more or working longer. while saving more might seem like a good idea, working longer often becomes the more practical choice, given that many people can’t save enough. but simply raising the retirement age won’t solve the problem. many governments have already raised retirement ages, but these measures alone aren’t enough. more comprehensive reform is needed.

making longer careers possible requires more than just delaying retirement; it means maintaining people’s ability to earn. this means focusing on health, education, skill updates, and making jobs better suited for older workers. tackling ageism is also important to ensure older workers aren’t overlooked. creating workplaces that are age-friendly – like offering flexible hours and reducing physical strain – will help workers stay productive longer. additionally, policies should promote lifelong learning, so older workers can transition to new roles and stay adaptable in changing industries.

but what do you need to do to plan for your own longer career? start by investing in your health and skills now. plan for mid-career shifts, building financial security and staying open to moving into less demanding roles as you age. embrace flexible work and lifelong learning to keep yourself engaged and productive. longer, productive lives can benefit the economy and challenge the idea that aging populations are a financial burden. but policies must also reflect the diversity of needs, especially for those in poor health or with limited education. consider these factors in your own planning.

from a financial standpoint, a longer life means you’ll need more savings. the ongoing pensions crisis, with many systems underfunded, adds urgency to this need. managing those savings wisely is essential, especially with the shift from defined benefit to defined contribution schemes, which place more responsibility on individuals. consider options like living insurance or annuities to help reduce the risk of outliving your savings. financial literacy and systemic reforms are key to supporting you through these challenges. regularly reassess your financial plans, and don’t forget to invest in your health and skills to ensure long-term security in an uncertain world.

why should we even want to live longer? it’s a question that shifts the focus from how we extend life to why it matters. longevity is only meaningful if those extra years bring purpose, fulfillment, and joy. simply adding years without considering how they’re lived – like hoarding time as if it were treasure – can feel empty. the real value of longevity lies in the relationships we nurture, the meaning we create, and the quality of the experiences we embrace.

bertrand russell once compared aging to a river, which grows broader and deeper as it flows, suggesting that later years can foster growth and self-discovery. david bowie spoke of aging as a process of peeling back layers to reveal your truest self, showing how these transitions can enrich life. but these opportunities for growth depend on rethinking how society views aging. too often, older people are marginalized, seen through a lens of decline rather than potential. this perspective isn’t just limiting, it’s harmful, undermining the ability to find meaning in later years.

there’s also the risk of losing sight of quality in the pursuit of longevity. strict practices like joyless fasting or obsessive health regimens often promise longer lives, but at what cost? jorge luis borges explored this idea in his story the immortal, where he portrays eternal life as a paradox – life becomes meaningless and achievements are stripped of value. without engagement or cultural support, extra years can feel more like an obligation than an opportunity.

living longer doesn’t happen in isolation, of course. as life spans increase, generations will overlap in ways never seen before, reshaping family, societal roles, and even opportunities. young people now face a future where living into their 90s is common, but that future also comes with challenges: rising health issues, stagnant wages, crushing debt, and an unstable housing market. these struggles are compounded by broader uncertainties like climate change and evolving technology, which demand adaptability and resilience.

for longevity to be a shared opportunity rather than a source of friction, collaboration across generations is essential. it’s not about dividing resources or attention but finding ways to support one another. with thoughtful policies and a collective commitment to fairness, longer lives can enrich not just individuals but entire communities.

as people live longer, the way we think about life’s stages, social norms, and institutional priorities needs to evolve. this shift isn’t simple – resistance is natural when changes challenge deeply held habits or systems. the agenda for longer lives, much like efforts to combat climate change, demands a persistent focus on future-oriented strategies. a key component of this is promoting healthy aging, which involves extending not just the years of life but also the productivity and sense of purpose throughout them.

the challenges are pressing. in places like the us and uk, where life expectancy is declining, the progress achieved in longevity is at risk. this “shortgevity” trend highlights how essential it is to shift societal priorities. stereotypes about aging often obscure the importance of later-life health, while governments underemphasize the value of healthy life expectancy as a fundamental measure of welfare.

the health-care system, too, needs a major overhaul. current approaches favor interventions over prevention, despite evidence that preventative measures can yield more significant long-term benefits. shifting incentives in the pharmaceutical industry can encourage treatments that add healthy years, not just more years. large-scale government-led initiatives in longevity research, like past innovation projects, can also play a transformative role.

demographic trends add another layer of complexity. longer lives typically correspond with declining fertility, which presents challenges for balancing population dynamics. policies that make parenting more affordable and flexible are essential to addressing this issue while supporting families in adapting to these shifts.

at an individual level, you should also prepare for a longer life proactively. stay healthy, financially secure, skilled, and connected. this will require effort but will pay off in resilience and fulfillment. strong relationships are particularly important. they’ll provide you with emotional support and a sense of purpose that sustains your well-being throughout life’s ups and downs. by embracing these challenges and opportunities now, you’ll help pioneer an “evergreen” approach to aging – one that benefits not just today’s society but also generations to come.

the main takeaway of this chapter to the longevity imperative by andrew j. scott is that longevity offers immense opportunities – but only if approached proactively with a focus on health, financial security, and purpose. by rethinking aging, individuals and societies can transform extended lifespans into fulfilling and meaningful experiences.

thriving in a longer life starts with prioritizing your health. adopting healthy habits like balanced nutrition, regular exercise, and cultivating relationships can prevent or delay many age-related challenges. your goal isn’t just to live longer, but also to extend your healthspan – the years you spent in good health – allowing you to experience more vibrant and fulfilling years of life. financial and career security are equally important. a longer life requires planning for an extended career, lifelong learning, and flexible retirement options.

your longevity is only meaningful if those extra years bring you purpose and joy. so nurture your relationships, embrace personal growth, and encourage intergenerational collaboration. 

by reframing aging as an opportunity rather than a burden, we can create a society that empowers people of all ages to thrive and contribute.
