Many of us dread aging—we associate it with loss, decline, and loneliness, believing that life inevitably gets worse as we get older. But our fears don’t tell the full story. In Joyspan (2025), gerontologist Kerry Burnight argues that anyone can learn to embrace aging joyfully. In doing so, you lengthen what she calls your “joyspan,” the number of years you maintain optimism and a sense of fulfillment. She offers several research-backed strategies for lengthening your joyspan and explains how this is integral to living a long, healthy life. She recommends implementing these strategies at any age, whether you’re 18 or 80, because doing so can help you squeeze as much joy as possible out of the rest of your life.

Joyspan Summary Part 1: Understanding Your Joyspan

Drawing from the ideas of religious leaders Desmond Tutu and the Dalai Lama, Burnight defines joy as a steady state of optimism and fulfillment. Unlike fleeting bursts of pleasure, joy is stable and enduring—it can persist even in the face of hardship, and it helps you achieve a better overall quality of life no matter what the universe throws your way. So, the longer your joyspan, the longer you can maintain a higher quality of life, which makes those extra years feel like they’re worth living.

The other three—fear, anger, and sadness—can create suffering, making joy the only emotion that explores what’s good and satisfying about the human experience. Further, Tutu and the Dalai Lama argue that the purpose of life is to alleviate suffering through the discovery and practice of joy. This not only benefits you (as Burnight argues) but also your friends, family, and community—which is another reason to consider lengthening...

Now that we’ve discussed why joy is essential to your wellbeing as an older adult, let’s talk about how you can experience more joy. In this section, we’ll cover Burnight’s six strategies for lengthening your joyspan: embracing a healthy mindset, maintaining physical health, steadily evolving, adjusting to change, prioritizing relationships, and helping others. As we’ve discussed, it’s never too late to start applying these strategies—no matter how old you are, taking steps to embrace joy can significantly improve your quality of life going forward.

Strategy #1: Embrace a Healthy Mindset

Burnight explains that you can approach aging with one of two mindsets:

An unhealthy mindset sees aging as a negative experience—you feel powerless, overwhelmed by loss, and as if you lose value with each passing day. As a result, you surrender to the challenges aging presents rather than trying to meet or overcome them. This negatively impacts every aspect of your life, which in turn diminishes your longevity.

(Shortform note: If you feel powerless and surrender to challenges rather than trying to face them, you likely suffer from what positive psychologist Martin Seligman calls...
