biological aging
is associated with a reduction in the body’s potential to repair and regenerate tissue.
Gerontology
is the scientific study of the physical changes that occur with aging.
social aging
refers to the shifts in our relationships and societal roles as we age.
These changes are often the result of major life events such as retirement, changes in income, deaths of family members and friends, or moving to a new location. These changes may occur abruptly and sometimes result in rapid deterioration in self-identity and social functioning.
Psychological aging
refers to the cognitive, emotional, and behavioural changes that naturally occur in humans over time.
These include a gradual decline in cognitive processing speed, memory, and other mental functions, which occurs in most healthy older people.

Reimagining Aging
There are many advantages of aging:
——–As we age, we acquire skills, wisdom, a sense of history and perspective that only time can provide
Knowledge and wisdom make up for a loss of cognitive speed
Need to appreciate the knowledge, productivity and wisdom of the growing numbers of older citizens
Happiness follows a U-shaped curve
Least happy in middle age and happiest in youth and older years
Defining Death
Cessation of the flow of vital body fluids
—–Heart stops beating and breathing ceases
Cellular death is a gradual process after the breathing and heart stops
—–Irreversible changes in cell metabolism
