Lifespan is how long you live. Healthspan is how long you live without significant disease. PerformanceSpan is narrower and more useful: the years in which you remain strong, fit, energetic, mobile and capable of doing what you actually want to do.
Framed that way, the priorities change. The goal stops being avoiding illness and becomes protecting capability — strength, cardiovascular fitness, movement quality and the energy to use them.
What extends PerformanceSpan
- Resistance training maintained across decades rather than in bursts.
- Regular cardiovascular work, including some genuinely hard efforts.
- Enough protein and enough overall quality in ordinary meals.
- Recovery and sleep treated as part of the plan.
Think in decades. The decisions that decide your sixties and seventies are being made now.
- Identity
- Willingness
