One Thing to Age BetterOne of the most worthwhile efforts I make is cutting through the noise—the pseudo-fitness gadgets, miracle supplements and time-wasting trends. The problem is, most people don’t have the time or the patience to separate what works from what’s nonsense. So I do. At age 40, I needed medical clearance to qualify for arduous duty as a wildland firefighter. Because of my family history—my father died of a heart attack at 53—I was required to pass an exercise stress test. I remember sitting with the cardiologist, Dr. Smith. He sensed my anxious thinking. “I have 13 years?” After confirming that my heart and circulatory system were healthy, he said something that stayed with me: “Your father’s heart attack is not prophecy. It’s information. If you choose to live differently, your outcome can be different.” I’ve been developing and testing that idea—living it, refining it—for nearly 30 years.In my March newsletter, I wrote that the longevity I’m pursuing is performance longevity. I don’t want to simply live longer, dependent and limited. I want to be hiking, climbing, and fly-fishing in remote, roadless places regardless of age. That perspective aligns with what physician-researcher Eric Topol said in a recent interview: “If we could live to 85, totally intact, that would be a phenomenal advantage.” But that kind of outcome doesn’t come from fascination with longevity. It comes from commitment. Today, many people are captivated by the idea of living longer. It’s compelling. It’s marketable. But it pulls attention away from something more important: living better now. Most of the flashy tools—biological age tests, full-body scans—create the illusion of control without meaningfully improving daily life. They measure, but they don’t move the needle. What does? Effort.Here’s a personal update: all four of my brothers—both older and younger—have had stents or bypass surgery. I have had neither. During my most recent 2025 exercise stress test, the physiologist remarked: “I’m impressed how you continue to exceed the expected maximum heart rate for your age.” That’s not a story about genetics. It’s a story about alignment. And here’s the real takeaway:I am not the story. The human body is. When you align your lifestyle with biology—how your body is designed to function—it responds. It adapts. It reveals capacity you might not expect. The leverage isn’t in a device, a test, or a trend. It’s already in you—latent and waiting. You activate it with consistent, deliberate effort. If my work has changed how you think about aging, consider sharing your thoughts. A review of my book The Ageless Angler helps others find this work and see what’s possible. Stay Well!

Bob Marshall Wilderness Complex, Montana Muscle is your engine for aging well. It allows you to climb stairs, carry groceries, pick up the grandchildren hike trails, recover from a stumble, and remain independent. As we age, that engine slowly loses horsepower—but it doesn't have to. Muscle mass shrinks with age. We lose strength and power—all the things that fuel an active life. Beginning around age 35, most adults begin losing muscle at roughly 1–2 percent per year unless they actively work...
In the past, I shared with you research that shows the genetic contribution to health and longevity accounts for an estimated 25% contribution. As recently as 2026, another researcher quantified heritability at 50 %, mentioning that researching human life is challenging and full of confounding factors that are difficult to pin down. My personal experience (and maybe yours too) points directly to this challenge. I have outlived my dad and my older brother by 20-plus years. In addition, my...
Capacity for the Season It’s trout season—fishing season, in fact. If you haven’t been exercising throughout the winter, you may feel under the gun, tempted to compress your effort to get in shape into a short window before the season begins. That’s not optimal, but your something is better than nothing. To maximize effectiveness in a short window of time, focus on what matters most. Cardiorespiratory fitness is known as the holy grail of longevity and health span. It also delivers something...
