Zest, enthusiasm, vigour, energy
Vitality is an approach to life marked by an appreciation for energy, liveliness, excitement, and energy. A vital person lives life as an adventure to be approached whole-heartedly. A life of vigour allows one to experience the overlap of the mental and physical realms of experience, as stress decreases and health increases. Vitality differs from contentment in that it involves greater psychological and physiological activation and enthusiasm.
