Health-related quality of life (HRQOL) measures are used to assess the multifaceted impact of disease, and determine the utility and associated disability. In addition, the impact of medical interventions must be assessed by psychometrically robust HRQOL measures based on a comprehensive and dynamic model. To develop such a model, the concepts of life, its quality, domains, essence, and purpose must be properly and clearly understood. The correct understanding of these entities is specifically important for patient-centered medicine and has universal implications for all fields of human endeavor. Therefore, in order to explore questions about life and quality of life adequately, every necessary field of knowledge should be employed. A multilinguistic and etymological appraisal reveals that life is related to medicine, freedom, being, soul, and spirit, all of which must therefore be considered in its conceptualization.
