This phrase is relative because what is seen as quality of life in one place or time may not be the same for another place or the same place at another time. It also relative because different people will perceive 'the good life' in different ways depending on their position in society. These issues aside, quality of life may be taken to mean 'life satisfaction' or 'subjective well-being' (see, for example, the American Thoracic Society, 2002). As such, quality of life has a number of dimensions, including (a) physical and material well-being; (b) relationships with other people; (c) engagement in social, community and civic activities; (d) personal development and fulfilment; and (e) recreation.
