Question: who is quality of human being is necessary to lead a happy life

title: Quality of life
text: Unlike per capita GDP or standard of living , both of which can be measured in financial terms , it is harder to make objective or long - term measurements of the quality of life experienced by nations or other groups of people . Researchers have begun in recent times to distinguish two aspects of personal well - being : Emotional well - being , in which respondents are asked about the quality of their everyday emotional experiences -- the frequency and intensity of their experiences of , for example , joy , stress , sadness , anger , and affection -- and life evaluation , in which respondents are asked to think about their life in general and evaluate it against a scale . Such and other systems and scales of measurement have been in use for some time . Research has attempted to examine the relationship between quality of life and productivity . There are many different methods of measuring quality of life in terms of health care , wealth and materialistic goods . However , it is much more difficult to measure meaningful expression of one 's desires . One way to do so is to evaluate the scope of how individuals have fulfilled their own ideals . Quality of life can simply mean happiness , the subjective state of mind . By using that mentality , citizens of a developing country appreciate more since they are content with the basic necessities of health care , education and child protection .
