Healthspan Over Lifespan: A Better Goal for Healthy Aging
By Carmen Désart
Do you want to live longer—or simply live better?
You're certainly not alone. Interest in longevity and healthy aging has grown tremendously over the past decade, fueled by advances in nutrition science, exercise physiology, and our understanding of metabolism. It's easy to see the appeal. Most of us hope to maintain our strength, independence, mental clarity, and vitality as we grow older.
Yet despite the excitement surrounding longevity research, it's important to recognize that the science is still evolving. Rather than focusing solely on adding years to life, a more practical and evidence-informed goal is improving healthspan—the number of years we remain healthy, active, and able to enjoy life.
Exercise: One of the Most Powerful Tools We Have
Among the many lifestyle factors associated with healthy aging, regular physical activity consistently stands out as one of the most effective.
Research has demonstrated that physically active adults in their seventies can maintain muscle mass and physical function comparable to much younger inactive individuals. Even approximately six hours of weekly exercise, divided between aerobic activity and resistance training, has been associated with meaningful improvements in strength, mobility, metabolic health, and cognitive function.
Resistance training is particularly important because skeletal muscle serves purposes beyond movement. Muscle functions as an endocrine organ, releasing signaling molecules known as myokines, which influence blood glucose regulation, immune function, brain health, and overall metabolic well-being.
In other words, maintaining muscle isn't simply about appearance—it's an investment in long-term health.
Aging Remains Complex
Although exercise offers remarkable benefits, it cannot completely prevent every biological change associated with aging.
Researchers continue to investigate age-related changes within mitochondria—the energy-producing structures inside our cells—including declines in mitochondrial calcium transport that may contribute to reduced muscle performance over time.
Early laboratory studies have explored naturally occurring compounds such as oleuropein, a polyphenol found in olive leaves and olives, for their potential role in supporting mitochondrial function. While these findings are scientifically interesting, they remain preliminary, and additional human research is necessary before drawing clinical conclusions.
A More Practical Perspective
The goal of healthy aging isn't to chase every new longevity trend.
Instead, it's to consistently invest in the habits that have repeatedly demonstrated benefits across decades of research:
Regular physical activity
Resistance training
Nutrient-dense whole foods
Quality sleep
Stress management
Meaningful social connection
These practices may not promise extraordinary longevity, but they consistently support better metabolic health and improve quality of life.
Ultimately, we cannot control every aspect of aging, but we can influence how we care for our bodies throughout life.
Rather than viewing longevity as a race against time, I believe we should view it as an opportunity to move with intention, nourish ourselves thoughtfully, and pursue strength—in body, mind, and spirit.
Because living well today may be one of the most meaningful investments we can make in tomorrow.
