Document Summary

The biological determinants are more proximate to health: the biological determinants thus affect the biological determinants. Car analogy: like of car depends on 4 elements: design------genes, accidents------external agency, maintenance -----internal agency, aging-----aging. Who 3 common causes of disease: communicable, non-communicable. Genes: genes matter in relation to other components of health, less than 2% of illness related to 1 gene locus. External agency: environment as threat to well-being, pathogens. Aging: result of entropic decay inherent in metabolic process, we can delay/speed our aging by our behvrs.

Epigenetics: can choose what genes to express- thus your genes from birth are not necessary stuck. More likely to die from non-communicable diseases than communicable diseases and that is largely revolved around our behvr and so the interplay b/w the host and environment- internal agency.
