Four Processes of Aging • Chronological Aging • Biological Aging • Psychological Aging • Social Aging
What is Aging? • Aging • Changes that occur to an organism during its life span, from development to maturation to senescence • Intragenerational Diversity • Young-Old (ages 65-74) • Old-Old (ages 75-84) • Oldest-Old (ages 85 and older)
An Active Aging Framework • Active aging • Emphasis on autonomy/choice with aging • A model of viewing aging as a positive experience of continued growth and participation in family, community, and societal activities, regardless of physical and cognitive decline
Person-Environment Perspectiveon Social Gerontology • A model that suggests that the environment is not a static backdrop, but changes continually as the elder takes from it what he/she needs, controls what can be modified, and adjusts to conditions that cannot be changed
Growth of the Older Population • Changes in Life Expectancy • Females born in 2005 are expected to reach 80.4 years • Males born in 2005 are expected to reach 75.2 years • Even in 2050, male life expectancy will be less than 80 years; females will achieve 84.3 years
