Life Expectancy
The upper boundary of the human life span is 122 years
Life expectancy in the U.S is about 77years
People are living longer in part due to better sanitation
nutrition medicine
The rapid increase in life expectancy has negative implications for quality of life for older people.
Society reflects the needs of younger people:
• Parks, transportation systems, & so on are built assuming they are used only by able-bodied people.
• Planning & building does not consider the needs of low-strength or low-stamina people.
The focus has been on what older adults lack, not what they can contribute to society.
• Older citizens can share deep expertise & motivation to make a difference.
, Characteristics of the life-span perspective
Development has these qualities:
◦ Lifelong
◦ Multidimensional
◦ Multidirectional
◦ Plastic
◦ Multidisciplinary
◦ Contextual
◦ It involves growth, maintenance, & regulation of loss
◦ It is a co-construction of biological, sociocultural, & individual factors.
Types of contextual influences
Normative age-graded influences are similar for individuals in a particular age group.
• For example, starting school, puberty, menopause.
Normative history-graded influences have common generational experiences due to historical events.
• In the 1930s, the Great Depression; in the 1960s & 1970s, the civil rights & women's rights
movements; in 2001, the attacks on 9/11.
Non-normative life events are unusual occurrences that have a major life impact.
• For example, early pregnancy, losing a parent as a child, winning the lottery.
