Attia defines longevity as maximizing both the length and quality of life, then makes a sharper point: even if you do everything right — diet, sleep, exercise — lacking emotional health means you may not live as long. And regardless of lifespan, if it's unhappy, why bother. The implication is that emotional health is not a 'nice to have' alongside longevity metrics; it's the prerequisite that determines whether the rest matters.
