Document Summary

Aging: definitions, mechanisms and the magnitude of the problem. It would be detrimental to live longer but suffering from a chronic disease. Relies on a dynamic interaction b/w le and the age of onset of a chronic illness or disability, to be successful there must be a compression of morbidity. Muslims during ramadan have an increase in hdl. A japanese island consumes fewer calories than the mainland and have a higher average le. A restricted diet leads to less cancer and cvd and a longer le: neuro-endocrine theories. Neurons do not divide or replicate and are therefore not replaced, they must survive as long as we do. Known that senescence is associated with a decline in neuro-endocrine cells. Suggests that the hypothalamic-pituitary glands are the regulators of senescence as they control hormones which regulate endocrine glands: genetic theories, programmed theories. Aging is the result of a pre-written programme.
