The Longevity Imperative: Aging Like Evergreen Trees!

As human beings, we’ve long viewed ageing through a lens clouded by fear—like the withering leaves of autumn. But what if we started seeing ageing as something different? Not as an inevitable fall but as an evergreen tree, continuously thriving, adapting, and growing? The world is changing, and so is our understanding of ageing. In Andrew J. Scott’s book, “The Longevity Imperative: Building a Better Society for Healthier, Longer Lives,” we’re not just urged but empowered to think of ageing in new, empowering ways. He explores the implications of increasing life expectancy and the necessity of enhancing the quality of our later years. As we stand on the threshold of a new era where living into our 80s, 90s, or even beyond is becoming commonplace, Scott urges us to rethink not just how long we live but how well we live. This shift not only helps individuals and societies move from merely counting years to making those years count but also inspires us to embrace this new perspective with vigour and determination.

Why Living Longer Isn’t Enough: The Healthspan-Lifespan Balance

When we think of a longer life, we tend to imagine it like a marathon where we cross the finish line exhausted. But what if we could run this marathon with the vitality of our youth? This is the difference between focusing on lifespan (simply living longer) and healthspan (living well during those years). Imagine life as a long journey across a vast landscape. As we travel, we accumulate experiences, relationships, and wisdom. However, if we neglect to maintain our vehicle—our health—we risk breaking down along the way. Scott emphasises that merely extending the number of years we live is not enough; we must prioritise our “healthspan,” ensuring that those years are filled with vitality and purpose.

Take the example of extending life expectancy by one year in the U.S., which, if coupled with better health, adds far more value—nearly $180,000 per year compared to only $100,000 if life expectancy rises without improving health​. This illustrates that quality of life matters as much, if not more, than the number of years we live. It’s a comforting reassurance that our focus on living well is not in vain and that the quality of our years is what truly counts.

The Key to Longevity: An Evergreen Approach to Aging

Ageing, as Scott emphasises, is not about reaching an inevitable “old age” destination. It’s more like tending to a garden. The more care we invest in ourselves—like sunlight, water, and good soil—the better we thrive. This proactive mindset, which mirrors what Scott calls the “evergreen” approach to ageing, is not just a suggestion but a call to action. This means viewing ageing not as a decline but as an ongoing process—a journey that requires care and attention at every stage. It’s a commitment to mental and physical wellness, ensuring that we remain green year-round, thriving in every season of life. By focusing on where we fall on the “health and frailty” spectrum rather than just our chronological age, we can better understand and support healthy ageing. It’s a powerful reminder that we are in control of our ageing process and that our actions can significantly impact our well-being.

Adopting an evergreen lifestyle means focusing on six key factors: avoiding smoking, limiting alcohol, staying active through regular exercise, combating obesity by maintaining a healthy diet, reducing social isolation by staying connected with friends and family, and lowering exposure to air pollution by living in clean environments. It’s like building strong roots to protect yourself from life’s inevitable storms​.

Scott argues that to fully embrace this imperative for longevity, society must undergo a significant shift in mindset.

Beyond Retirement: Reimagining Work and Purpose

Many think of retirement as crossing a bridge to a tranquil pasture, but Andrew Scott urges us to reimagine it as a time for continued productivity and fulfilment. Governments can support this by raising the retirement age and ensuring older people can keep contributing. The book offers a fresh perspective—like adding more chapters to your career book, where the plot gets richer and deeper with each page turn. Scott points out that most of the job growth in wealthy countries over the past decade has been due to workers over 50​, a clear sign that age doesn’t need to signal the end of productivity. In fact, keeping older workers engaged is essential for both personal fulfilment and economic prosperity.

Ageing Isn’t a Threshold, It’s a Process

We often think of ageing like flipping a switch: one day, you’re young, and the next, you’re “old.” But, as Scott points out, ageing is a continuous journey—like a winding river, not a single waterfall drop. Research shows that seeing ageing as a gradual process helps combat ageism, a pervasive societal bias. Instead of viewing old age as “damage” to society (as some might in Japan, coining the term rogai), we can see it as a continued opportunity for growth, contribution, and wisdom​.

Redefining ageing as an ongoing process is taking control of our narrative. It’s like upgrading a software program—each version brings improvements that make life more seamless, efficient, and enjoyable.

Six Principles for an Evergreen Approach

To sail this journey successfully, Scott outlines six principles:

  • Educate Yourself: Knowledge about health and longevity empowers better choices, like how knowing the rules of the road empowers safer driving.
  • Be Kind to Your Future Self: Investing in your health today for a better tomorrow is like putting money in a savings account that accrues interest over time.
  • Redefine Aging: By challenging societal perceptions and creating your narrative around ageing, you empower yourself. It’s as empowering as rewriting the ending of a book to better reflect your values and experiences.
  • Stay Informed: By keeping abreast of health advancements that could enhance your life, you stay engaged and proactive. It’s like regularly updating your phone to access new features and improvements.
  • Don’t Underestimate Yourself: Embracing your accumulated wisdom and potential for growth is similar to appreciating a well-aged wine that becomes richer and more complex over time.
  • Invest in Yourself: By committing to lifelong learning and self-improvement, you inspire and motivate yourself. It’s like tending to a garden, nurturing it over time to yield a bountiful harvest.

Adopting these principles encourages an evergreen approach to ageing that celebrates life at every stage.

The “Longevity Imperative” isn’t just a call to live longer but to live better, healthier, and more purposefully. It’s about realising that life, much like an evergreen forest, grows best with intentional care, resilience, and adaptability. Our longevity is not just about adding years to our lives but enriching those years with quality experiences and healthful living. Whether you’re 30 or 70, your health today is the soil for tomorrow’s well-being. By embracing this imperative collectively—through policy changes, societal shifts in perception, and individual commitment—we can build a healthier future for all generations. So, treat your ageing process as a lifelong adventure, one where the destination is less important than the steps you take along the way.

By adopting an evergreen approach, we won’t just be living longer; we’ll be thriving in every season of life. And isn’t that the most fulfilling goal of all? A compelling read! Get your copy.
