Old Age Flashcards
(83 cards)
prejudice or discrimination based on age
o Ageism
– gradual, inevitable process of bodily deterioration that begins early in life and continues through years irrespective of what people do to stave it off (nature
o Primary Aging
results from disease, abuse, and disuse – factors that are often within a person’s control (nurture)
o Secondary Aging
65-74 yrs old
o Young Old
75-84 yrs old
o Old Old
85 and above
o Oldest old
how well a person functions in a physical and social environment in comparison with others of the same chronological age
o Functional Age
study of the aged and aging processes
o Gerontology
branch of medicine concerned with aging
o Geriatrics
the age to which a person born at a certain time and place is statistically likely to live, given his or her current age and health status
o Life Expectancy
actual length of life of members of a population
o Longevity
death rates
o Mortality Rates
longest period that members of our species can live
o Human Life Span
– the decline in body functioning associated with aging
o Senescence
propose that people’s bodies age according to instructions built into genes and that aging is a normal part of development
o Genetic Programming Theories
aging also may be influenced by specific genes “switching off” after age-related losses occur (Epigenesis)
o Programmed Senescence Theory
o Telomeres become shorter as the cell divides (cells can divide for no more than 50 times
Hayflick Limit
– biological clocks act through hormones to control the pace of aging
o Endocrine Theory
programmed decline in immune system functions leads to increased vulnerability to infectious disease and thus to aging and death
o Immunological Theory
Aging is an evolved trait thus genes that promote reproduction are selected at higher rates than genes that extend lives
o Evolutionary Theory
aging is the results of random processes that vary from person to person (Error theories
o Variable-Rate Theories –
– cells and tissues have vital parts that wear out
o Wear-and-Tear Theory
Accumulated damage from oxygen radicals causes cells and eventually organs to stop functioning
o Free-Radical Theory –
the greater an organism’s rate of metabolism, the shorter its life span
o Rate-of-Living Theory
