On the meaning of ‘aging’
Primary aging (or just ‘aging’) – 1normal, 2disease-free, 3age-related changes which occur
throughout adulthood. This is the basic meaning of the term, and the key concern of this
course.
- Aging not a disease
o Example, Nobel Peace Prize prof who just pasted away still active in research
near death
•‘Secondary aging changes related to disease, lifestyle, and environmental factors that are
not intrinsically part of aging per se.
- Not related to aging per se
o Lifestyle environments
Hearing in industrial environments vs rural
Ppl in rural places have much better hearing
•‘Tertiary aging rapidly occurring decline that occurs shortly before death
The ‘ seven ages of life’ according to Shakespeare (From: ‘As you like it’ 1600)
- Aging expections differs according to different historical periods
Western Division of the human lifespan
Currently, in the West, the human lifespan is subdivided into a number of periods, such as the
following :
•Infancy
•Childhood
•Adolescence
•Adulthood
- (emerging adulthood period is questionable period, us as uni students)
- Young Adulthood (20-40 yrs)
- Middle Adulthood (40-65 yrs)
- Late Adulthood (65 yrs and older)

Only pages 1-2 are available for preview. Some parts have been intentionally blurred.

The division of the lifespan into distinct periods
•Is accomplished by using so-called ‘markers’, which can be
- Biological
o Easiest to measure puberity, ability to walk. Completion on physical growth
18-21
- Psychological
o Mental & emotional levels development
Example, able to make long term plans & commit
Variable among culture
Subjective sense of decline
Wisdom, controversial
- Sociological
o Example, becoming a parent
HOWEVER, one can be one at age 40 or even never
- Not 1 of 3 is significant to define an adult, needs to be a combination
A key problem associated with the use of such markers
•is that there are no universally valid, age-related markers that can clearly, meaningfully, and
unambiguously demarcate the various periods of human life
•Because of this, some critics contend that we would be better off avoiding the use of such
markers altogether
The great surge of interest into issues related to adulthood and aging
- is importantly related to major demographic changes that have taken place worldwide,
most notably among the more economically advantaged societies (wealthy G8
countries)
- wealthy countries had an aging population
The ‘Squaring’ of the Population Pyramid
•Current major demographic changes are expected to progressively lead to populations
whose age distribution morphs from a pyramidal (triangular)shape, with many young
