A philosophy of health: life as reality, health as a universal value 2020-03-18 .txt text/plain 9761 475 40 The biological immune system, an individual's system of health behaviors, and the social system will be observed as systems that generate maintainable-ease of functioning in cells, selves, and societies respectively (Fig. 2 ). To observe health at the level of the cell, the self, and the society simultaneously, we consider systems that support maintainable-ease of biological, behavioral, and social functioning. Through this philosophy, one can go beyond biological systems to observe how precision (in the form of hostdefense functions, decision-making/executive functions, and values) and variation (in the form of microbiota functions, habits/habitual life functions, and population-wide behaviors) integrate to generate to maintainable-ease of functioning in cells, selves, and societies simultaneously (Fig. 3) . Similarly, when behavioral and social exposures are not tailored to the needs of individuals and groups, populations can become resistant to healthy change, and health is no longer valued at the level of the self and the society. ./cache/cord-264749-m1awr1rm.txt ./txt/cord-264749-m1awr1rm.txt
