If you’ve ever dabbled in looking into how to extend your life, your social media feed might be inundated with the “hottest” longevity trends: from cold plunges to VO2 max tests to celebrity-endorsed supplements. As a society, we are obsessed with the idea of living longer.
And longevity has become a multi-billion dollar industry where everyone’s trying to sell you their secret to a longer life. But if you meet the people leading that movement, you start to ask yourself “are they even happy?” If we’re all trying to live all these extra years, we should also make sure we genuinely enjoy them.
That’s why I wanted to talk to Dr. Kerry Burnight about how we age. Known as “America’s Gerontologist”, she specializes in the mental, physical, and social aspects of aging. Kerry has spent two decades as a professor of geratric medicine, and co-founded the nation’s first elder abuse forensic center, where she saw older people isolated, exploited, and suffering. After years of arriving after the damage was done, she started asking a different question: what would prevent that suffering in the first place?
Kerry’s answer is a concept she calls “Joyspan,” which is also the title of her New York Times bestseller Joyspan: The Art and Science of Thriving in Life’s Second Half. Her work reframes how we think about our long lives: not as a problem to solve by suppressing the aging process, but as a chance to grow with age and build a life with intention and joy.
In this episode you’ll learn:
➡️ Why the longevity movement lost its way (in a word: humility)
➡️ How Kerry’s mom changed her outlook on life in her late 70s, and is thriving at nearly 98
➡️ Three questions you should ask yourself every birthday
➡️ Why we should stop “growing older” and start “growing with age”
➡️ The one sentence that helps you find something good even when things are hard
➡️ How to help someone who’s stuck, without just commiserating
➡️ Why friendship might be “the Ozempic of longevity”
➡️ The four practices of people who are still loving life at 100
This conversation isn’t about rejecting the gym or the green vegetables – you should take care of your body too! But the parts of life that make it worth living are often difficult to assign a metric. They take work too. And it’s never too early (or too late) to start.
This… is A Bit of Optimism.
