摘要：Concern about the quality of life is to a great extent learned and rational. It arises from what humans learn about life, death, incapacitation, suffering, health, and success and from the realization that they need to know more about the quality of life to make decisions. And although during the decision-making process they may be prompted by instinctive impulses, in the main, quality of life decisions are arrived at through deliberating alternatives, predicting the consequences of following. Happiness, life satisfaction and subjective well-being are mutually interrelated – and indeed they are all closely connected with the notion of quality of life – but they are also highly contested constructs.
