What is meant by vitality?

Vitality refers to the condition of being strong, active, and full of energy. It encompasses not just physical strength but also an overall state of well-being and liveliness. This concept is often associated with youthfulness and a robust health status, suggesting that individuals who possess vitality are typically more engaged in life and able to participate in various activities with enthusiasm.

While other choices mention related concepts, they do not encapsulate the essence of vitality. For example, a decline in energy and activity would contradict the idea of being vibrant and engaged. A measure of life expectancy could relate to overall health but does not specifically highlight the active and energetic aspect of vitality. Enhanced cognitive functions, while important for overall health, focus on mental aspects rather than the physical and energetic vigor that vitality emphasizes. Thus, the definition that best aligns with vitality is the state of being strong and active.
