Document Summary

Distinguish between chronological age & functional age & discuss changes in life axpectency over the past century. People age biologically at diff rates, making chronological age an imperfect indicator of fucntial age. Dramatic 20th century gains in average life expectancy confirm tha tbioloigcla aging can be modified by environmental factors, including improved nturiton, medical treatment, sanitation, & safety. Length of life & especially average life expectancy (cid:272)a(cid:374) (cid:271)e predi(cid:272)ted (cid:271)y a (cid:272)ou(cid:374)try"s heatlh (cid:272)are , housing, & social services & lifestyle factors. With academic age, gender gap in average life expectancy declines, as do diff btw higher0-ses whites & low-ses ethnic minorities. Longevity runs inf aimlies but environmental factors become increasingly important with age. Scientits disagree on whether maximum lifespan can be extended beyond 22 years oldest verified age. Describe physical declines of late adulthood, including change sin the nervous & sensory systems. Neuron loss occurs thoughouth cerebral cortex, with greater shrinkage in frontal loes & corpus callosum.
