Quality of life (QoL) is the standard of health, comfort, and happiness experienced by an individual. The World Health Organization defines Quality of Life as ‘an individual’s perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns’. A Loop is your record of an experience and how it made you feel. Your Loops build over time as a collection of experiences and associated feelings that generates a Quality of Life Index (QoL Index) which is directly linked to the type of emotions you experience the most.
