Healthspan vs Lifespan: How to Age Better, Not Just Longer

Most people do not actually want more birthdays if those years mean frailty, isolation, and losing independence. The better target is healthspan: more years with mobility, cognitive clarity, purpose, connection, and the ability to do what you value.

In this solo episode, Dr. Hillary Lin breaks down the healthspan–lifespan gap: why acute-care systems are often better built to rescue illness than to protect long-term function, how work, cities, healthcare incentives, social norms, stress, sleep, food, and reward loops shape healthy aging, and what small practical habits can protect function over time.
