Right to health
The preamble of the consitution of the World Health Organisation defines it as  "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." It says that the right to health is fullfilled, when the person enjoys the highest attainable standard of health.  It also lists some examples, such as healthy child development, spreading medical knowledge among all people in the population, and a government providing social measures to provide adequate health.
