Vitality (Template:Etymology, Template:Etymology, Template:Etymology) 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]
Overview
The pursuit and maintenance of health and vitality have been at the forefront of medicine and natural philosophy throughout history.[4] Life depends upon various biological processes known as vital processes. Historically, these vital processes have been viewed as having either mechanistic or non-mechanistic causes. The latter point of view is characteristic of vitalism, the doctrine that the phenomena of life cannot be explained by purely chemical and physical mechanisms.[5]
Prior to the 19th century, theoreticians often held that human lifespan had been less limited in the past, and that aging was due to a loss of, and failure to maintain, vitality.[6] A commonly held view was that people are born with finite vitality, which diminishes over time until illness and debility set in, and finally death.[7]
Religion
In traditional cultures, the capacity for life is often directly equated with the Template:Em or Template:Em.[8] This can be found in the Hindu concept Template:Transliteration, where vitality in the body derives from a subtle principle in the air and in food,[9] as well as in Hebrew and ancient Greek texts.[8]

Vitality and DNA damage
Low vitality or fatigue is a common complaint by older patients.[10] Template:Clarify and may reflect an underlying medical illness.[10] Vitality level was measured in 2,487 Copenhagen patients using a standardized, subjective, self-reported vitality scale and was found to be inversely related to DNA damage (as measured in peripheral blood mononuclear cells).[10] DNA damage indicates cellular disfunction.
