Particularly in the digital environment, critical analysis of health concepts helps us to better understand health policies and politics and their consequences. All modern concepts of health recognise health as more than the absence of disease, implying an individual's maximum capacity for self-realisation and self-fulfilment. In 1977, with the adoption of the WHO Global Strategy "Health for All by the Year 2000", a pragmatic concept of health was indirectly accepted: the ability to lead a socially and economically productive life, which was an essential objective of this strategy (1). The popular conception of a gene is "a strange collection of DNA and chromosomes and other things that determine whether or not you will get this type of cancer, how long you will live and whether you will have a coronary bypass at some point in your life".
Respecting this definition as an overarching concept, many researchers and theorists subsequently advocated the adoption of operational and practical definitions of health. The concept of health as the balance between the person and the environment, the unity of soul and body, and the natural origin of disease, was the backbone of the perception of health in ancient Greece. Being able to identify and recognise the individual conception of health is important, particularly when this conception of health contradicts recommendations for diseases that need medical intervention.
