Springtime by Émile Vernon, an artistic depiction of seasonal vitality
Vitality (from Middle French vitalité, from Latin vītālitās, from Latin vīta 'life') is the capacity to live, grow, or develop. More simply it is the property of having life. The perception of vitality is regarded as a basic psychological drive and, in philosophy, a component to the will to live. As such, people seek to maximize their vitality or their experience of vitality—that which corresponds to an enhanced physiological capacity and mental state.
