Accelerating medical breakthroughs and AI driven tech are increasing lifespans and healthspans, leading us to reimagine the wealthspan required to support them. The standard retirement model is a legacy of an era with shorter lifespans. Most planning is built on prudent modeling for living to age 90. Anchored by the fact that the average U.S. lifespan is 76 for men and 81 for women, these plans will fall apart if investors start to more frequently live to 100 or 110, requiring higher investment returns with greater consistency.
Convergence of Longevity
We have long heard about the Blue Zones around the world where people live longer, healthier lives: Okinawa, Sardinia, Nicoya, Ikaria, and Loma Linda have provided the blueprint for longevity through lifestyles of plant-rich diets, high activity levels, and strong social ties leading to exceptionally long lives with low rates of chronic disease.
The concept of healthspan has gained momentum, drawing rigorous attention to the need for lifelong exercise, the quality of what we consume, and the importance of personal connection. At the same time, we are witnessing a remarkable shift in medical technology, much of it driven by AI.
• Checkpoint inhibitors ignite the bodies cancer fighting mechanisms
• Genetic medicine is re-coding how we battle disease
• GLP-1s are improving metabolic health and weight regulation
• Wearables provide real-time health data
This blend of blue zone lifestyle principles and technological capability suggests that we are on the cusp of a significant jump in lifespan.
This conversation is essential because for years, the U.S. has been moving in the wrong direction. Our healthspan has been declining, leaving us 72nd globally behind Malaysia and just ahead of Serbia. On average, Americans spend their final 12 years of life incapacitated or struggling with chronic disease.
It is easy to be fatalistic about this and assume the trend of shorter lives and longer periods of ill health will continue. I believe the intersection of changing attitudes and medical technology will lead to a pivot toward longer heathier lives in the U.S. This necessitates us to rethink our investment philosophy in favor of higher returns and lower volatility, moving away from the classic process of swapping equity for fixed income in the post-retirement years.
