The Longevity Playbook: Closing the Gap Between Lifespan and Healthspan
“He who has health has hope; and he who has hope has everything.” — Thomas Carlyle
Happy Friday, Brew Nation!
The topic of longevity falls off the lips freely in many conversations these days—the market for longevity products, biohacks, and health tech has to be in the trillions.
It’s a topic I’ve studied over the last few years as I’ve watched my parents age.
It started when I read Dr. Gabrielle Lyon’s book Forever Strong. After that came the book that impacted me the most, The Power of Ownership. I’ve read other great books on the subject since—Peter Diamandis’ The Longevity Guidebook, Younger Next Year by Chris Crowley and Henry Lodge, MD, Outlive by Peter Attia, and even Jim Kwik’s Limitless talks about it.
Oh, and then there is the oldest book on the topic: The Bible! In Romans 12:1, Paul calls us to offer our bodies as a living sacrifice. Old Testament figures often lived long into three digits, and Daniel proved the undeniable value of healthy eating, too.
This is a topic that will continue to drive me.
Mind the Gap: Lifespan vs. Healthspan
In Dr. Peter Attia’s book Outlive, he highlights a powerful graph comparing Lifespan (the total number of years you live) versus Healthspan (the quality and vitality of those years).
Too many leaders spend decades grinding out success in business, only to experience a sharp decline in physical quality of life during their final years. They gain years, but lose vitality.
Here are the key pillars I’ve found to be most important to keep that healthspan curve high:
- Purpose: “I want to dance at my grandchildren’s wedding.” Having a clear, emotional “Why” keeps your daily actions aligned.
- Faith: I know I will not live forever. And while I certainly hope that I achieve my purpose, I am also fully aware that it is not totally in my control. Most importantly, I am deeply aware of what awaits me eternally.
- Sleep: This is where I’ve learned the most. Running a 3-2-1 routine (no food 3 hours before bed, no work 2 hours before, no screens 1 hour before), using mouth tape, and keeping the room at a cool temperature make all the difference.
- Exercise: Returning to Romans 12:1, moving the body was something I didn’t think I would miss. As I always say: I hate doing it, but I love having done it!
- Nutrition: You simply cannot out-exercise a bad diet. I journal my nutrition when I’m at my best, and key supplements have become critical to positively impacting my cholesterol, blood pressure, and overall health.
- Community: Accountability is key. Family and friends hold me accountable and keep me on purpose when I start to veer off course, and they affirm me when I’m staying on track.
The Continuous Improvement Flywheel
Healthspan isn’t a destination you arrive at once; it’s a continuous cycle—just like improving your business, your leadership, your relationships, or your family.
It requires an operational process:
- Identify your True North.
- Set measurable targets.
- Identify the barriers.
- Design solutions.
- Make changes.
- Verify it’s working.
- Reflect, and DO IT AGAIN!
Once you think you’re done… you’ve just begun.
Quote of the Week
“Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your body.”— 1 Corinthians 6:19-20
Being the Uncommon Leader means recognizing that physical stewardship is not a secondary thought—it is a primary responsibility. It is the “huddle room” of personal discipline, where true commitment meets daily action. Common leaders treat their bodies like rental cars, burning through energy until the system breaks down. Uncommon Leaders take total ownership of their healthspan so they can serve their families, their organizations, and the Kingdom for decades to come.

“Growth is the only guarantee that tomorrow will get better, but you need the energy and longevity to show up for it. Set your targets, audit your habits, and keep climbing. – John Gallagher”
