LONGEVITY:
What is the approximate number of years an individual may live up to?
Between 120-125 years
LONGEVITY:
Number of years that the average person born in a particular year will probably live.
Life Expectancy
LONGEVITY:
The term or name given to individuals that are 100 years and older.

An age referring to a person’s ability to function.
Functional Age
LONGEVITY:
The term for people aged 85 or more
Oldest-old
LONGEVITY:
The term for people aged 65 to 84.

LONGEVITY:
A biological theory of aging wherein natural selection has not eliminated many harmful conditions and nonadaptive characteristics in older adults.
Evolutionary Theory
LONGEVITY:
A biological theory of aging wherein cells can divide a maximum of 75 to 80 times, implying that age makes cells less capable of dividing.
Cellular Clock Theory
LONGEVITY:
Tips of chromosomes; DNA sequences that capture chromosomes
Telomeres
LONGEVITY:
A biological theory of aging wherein people ge because normal metabolic processes within cells produce unstable oxygen molecules that ricochet around inside cells, damaging DNA and cellular structures.
Free-radical Theory
LONGEVITY:
A biological theory of aging wherein aging is caused by the decay of the mitochondria.
Mitochondrial Theory
LONGEVITY:
A biological theory of aging wherein aging in the body’s hormonal system can lower resistance to stress and increase the likelihood of disease.
Hormonal Stress Theory
THE COURSE OF PHYSICAL DEVELOPMENT IN LATE ADULTHOOD:
Brain volume decreases due to 3 things. Namely..?
- Neuron Shrinkage
- Less Synapses
- Reduced Axon Length
THE COURSE OF PHYSICAL DEVELOPMENT IN LATE ADULTHOOD:
Generation of new neurons.
Neurogenesis
