Vitality

 . Vitality (from Middle French vitalité, fromLatin vītālitās, from Latin vīta 'life') is the capacity to live, grow, or develop.^[1] Vitality is also the characteristic that distinguishes living from non-living things.^[2] To experience 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.^[3]
