late aduldhood
starts in 60's, can be the longest age grouping in one's life if an individual lives
to old age
Do most older adults develop dementia?
No, It is not a normal part of aging. Only a small percentage of
65-to-75-year-old people have a neurocognitive disorder. However, this
number increases with age (50% of individuals 85 and older have a
neurocognitive disorder)_

What are some causes of neurocognitive disorders?
various diseases, severe drug/alcohol abuse, stroke, or progressive
deterioration caused by a variety of factors
Why do women typically outlive men?
Partly genetics, but mostly environmental. Men are more likely to engage in
risky behaviors, abuse drugs and alcohol, and be less vigilant about their
overall health.
primary aging
, the universal and irreversible physical changes that occur to all living
creatures as they grow older, genetically influenced, and thought to be
unavoidable at this point
secondary aging
aging that is not inevitable and occurs due to choices we make and
environmental exposures
"wear and tear" theory
States that time and exertion is the enemy, and focuses on secondary aging
but ignores the actual cause which is primary aging. However there are holes
in this theory: body does a great job at repairing itself, individuals who engage
in a lot of exercise and activity are typically healthier and longer-lived than
sedentary individuals,
free radical theory
theory of aging that states that free radicals triggered by certain environmental
contaminants might be linked to various diseases and maladies that coincide
with aging. Accumulating free radicals over time might be associated with
problems such as cataracts and arthritis
Cellular theories of aging
-Free radicals
-Hayflick Limit
Hayflick Limit Theory
states that human adult cells have a limited number of times that they can
divide (approximately 20). After this limit is reached, the cells will begin to die.
programmed cell death theories
focus on how cells appear to be designed to self-destruct in our genetic code.
A variety of processes contribute to this programmed cell death, and many of
the diseases associated with aging, such as osteoporosis and Alzheimer's,
have evidence of being at least partly caused by these processes.
