The quality of life is a systemic concept defined by the unity of its components: the human being properly as a biological and spiritual being, his/her activity and living conditions. It follows that the nomenclature of quality of life indicators should include both the objective characteristics of the person (or society) and the characteristics of subjective evaluation that reflect the subject's attitude towards the realities of his/her life. The most justified is the interpretation of the quality of life of people from the perspective of understanding the essence of human life as a process which generally aims at preserving and developing the life of mankind in an increasingly wide range of natural conditions, through creative activity and fighting, overcoming contradictions and natural, personal and social difficulties. In this article we will analyze in detail aspects of the formation and development of the quality of life.
