Document Summary
Women in mid 80s can live over 92. From 1981 to 2000 over 65 group increased by 2 thirds and over 85 tripled. Most older adults regard health as good. Chronic illness at age 65 predicts rapid decline later. Physical problems or disease like arthritis, hyper tension, obesity. Frail elderly with impairments so extensive cannot care for self. Measure of ability to do chores of daily living. Smoking, low level of activity, being under/over weight cause mortality. Live longer, low disease rate, high cognitive functioning. 30-60 mins of exercise daily can be in 10 min segments. Loss of dendrites (primary aging) linked to education: less cerebral cortex atrophy occurs in those with more education. Loss of dendrites causes slower synaptic speed, slows reaction time. Enlarged blind spot reduces field of vision. Cataracts, glaucoma, macular degeneration diminish visual acuity +adaptability. Age-related declines result from species genes for aging. Atoms with unpaired electron by-product of metabolism.
