Quality of life is defined as the level of enjoyment in a person's life. In general, it is based on many factors. At a minimum, a person's basic needs must be met for them to have a high quality of life---they must be generally healthy, have enough to eat and have a place to live. Once a person's basic needs are met, that person's quality of life is largely determined by their own personality, their desires and their level of personal fulfillment. A person with a high quality of life tends to feel as though all of their important needs and wants are fulfilled. They are generally happy and overall feel as though their life is good. A person without quality of life is lacking in one or several basic areas of his life. For example, the very ill or those who are no longer able to care for themselves or do activities they enjoy because of physical, mental or restrictions are often said to have a low quality of life.
