What are the theories of old age?
There are several error theories of aging: Wear and tear theory asserts that cells and tissues simply wear out. Rate of living theory is the idea that the faster an organism uses oxygen, the shorter it lives. Cross-linking theory states that cross-linked proteins accumulate and slow down the body’s processes.
What are the 2 major theories of aging?

What is Erikson’s theory of aging?

What is psychosocial theory of Ageing?
Psychological Theories on Health and Aging refer to approaches that explain how healthy aging can be promoted and how diseases can be prevented or delayed. They provide starting points for interventions to support adaptation to health-related changes that become more and more prevalent in later life.
Which major theory of aging is from the psychosocial perspective?
The activity theory
The activity theory is one of three major psychosocial theories which describe how people develop in old age. The other two psychosocial theories are the disengagement theory, with which the activity comes to odds, and the continuity theory which modifies and elaborates upon the activity theory.
What are the physiological changes in the elderly?
