Document Summary
Canada will not have a problem supporting the age population as long as we have some growth economically. Biological aging - decremental physical changes over time (structural and functional) Different from psychological again which is concerned about gains and losses. Life expectancy - average age maximum in a particular cohort; has been increasing; affected by facturs such as nutrition, sanitation, medicine available, etc. Life span - upper limit/maximum longevity of a specific member of a species; humans 120-122; stayed the same and not expected to change without further research about aging. Compression of mortality: greater amount of deaths occurring later on in life. Compression of morbidity: illness/disability occur only immediately before death. Primary aging (senescence) - unavoidable, universal, intrinsic biological processes; individual differences. Secondary aging - associated with defects in biological functioning resulting from hostile environmental influenced; evitable, not universal; extrinsic influences. Theories of biological aging *** midterm (remember which ones are which type and descriptions)
