How to Add Life to Your Years (Not Just Years to Your Life)

Somewhere along the way, living longer became a full-time job.

We track our steps, optimize our protein intake, and supplement stack like we’re preparing for a storm. We talk about lifespan in years, healthspan in metrics—blood sugar, VO2 max, bone density. All important, no question. But lately, I’ve been thinking about something we don’t measure nearly as often: how much we actually enjoy being alive.

Because what’s the point of adding years if they don’t feel like years you want to be in?

I keep coming back to this idea of a joyspan, the stretch of life where you feel engaged, connected, curious, and truly happy about your day. So I’ve started looking at it differently, not as another list to optimize, but as a handful of habits that make everyday life more enjoyable, while also supporting longevity. 

Let’s start here because it’s hard not to. It turns out, dog owners consistently live longer than non-owners. Studies1 have linked pet ownership to lower blood pressure, reduced cardiovascular risk, and even improved survival after heart attacks. But beyond the data, there’s something simpler happening. You’re moving more, you’re outside more, and you’re rarely alone.

If there is one thing the science of longevity keeps circling back to, it’s relationships.

The longest-running research we have, including the Harvard Study of Adult Development, has found that strong social connections are one of the most consistent predictors of a longer, healthier life. Not cholesterol levels. Not income. Relationships.

I notice it in my own life. The nights that stretch longer than planned because no one wants to leave the table. The friend you can call without rehearsing what you’re going to say. These moments regulate your nervous system, lower stress hormones, and quite literally change how your body ages.

Longevity, it turns out, isn’t a solo pursuit.

Somewhere in adulthood, play starts to feel optional. Like something we’ll get to after the “important” things are done.

But there’s a reason so many of the world’s longest-living populations build their days around movement that feels like play—walking, dancing, gardening, or sports2 like tennis. It’s not just exercise; it’s engagement.

Tennis, for example, has been associated with one of the largest increases in life expectancy among recreational activities. And it makes sense. You’re moving, reacting, thinking, connecting, all at once. It’s physical and social, and just competitive enough to keep things interesting.

You know that feeling when you’re somewhere new, and everything feels a little more interesting? You’re more observant, more present, a little more tuned in to what’s around you. Maybe the food is extra flavorful, the bustling streets bring you energy, or the coffee at that cute cafe is 10 times better than home. 

And this matters more than we give it credit for. Novel experiences stimulate the brain, support cognitive flexibility, and may even help build cognitive reserve, the brain’s ability to adapt as we age. In other words, curiosity is protective.

Time in nature changes your physiology in real, measurable ways. Studies on green space exposure show lower cortisol levels3, better mood, improved sleep, and even a reduced risk of chronic disease and early death. 

Awe is one of those emotions we don’t talk about enough, but it’s surprisingly powerful.

It’s that feeling you get watching a sunset, listening to music that hits just right, or standing somewhere that makes you feel small in the best way. Studies have shown that experiencing awe can reduce inflammation, shift focus away from the self, and increase feelings of connection4.

There’s a specific kind of satisfaction that comes from doing something just because you enjoy it. No outcome, no optimization, no productivity angle.

Reading5, cooking, painting, gardening—these aren’t just ways to pass time. They create a state of flow, where you’re fully absorbed in what you’re doing. That state has been linked to lower stress, improved mental health, and greater overall life satisfaction.

I’ve noticed that the weeks I feel the most like myself are the ones where I’ve made space for something creative or just enjoyable. For me, this looks like taking a pottery class or just finding a little extra time to bake. 

When you step back, all of these habits have something in common. They’re not just “good for you” in a clinical sense. They make your life feel fuller while you’re living it.

Joy is not a bonus, but a part of the foundation.

Lifespan tells you how long you live. Healthspan tells you how well your body functions. But joyspan, this softer, harder-to-measure thing, might be what makes the other two worth pursuing in the first place.

I still care about the basics. I lift weights, I try to eat well, I pay attention to sleep. But more and more, I’m starting to create space for a more joyful pursuit of health.
