Passage:
Quality of life is a broad concept, of which happiness forms only a part. Often the term refers to the quality of the living environment. Ecologists employ the phrase when appealing against environmental degradation; sociologists speak of it when evaluating a society. The term also denotes how well people cope and is commonly used in therapeutic professions. Medical doctors refer to the quality of life as the restored ability to work and love, while in the psychological discourse, the term refers to mental propensities, such as realism and vitality. Still, another characterizes the quality of life in terms of its outcomes; products and enjoyment. Products are what life leaves behind – in socio-cultural terms, a contribution to the human heritage, but from a purely biological perspective, procreation, for otherwise, the evolutionary mission ends in failure. As for enjoyment, the focus is on personal experience of life, and it is in this sense that happiness is subsumed.
