Working from Dr. Clayton’s framework, Monika Ardelt, an associate sociology professor at the University of Florida in Gainesville, felt a need to expand on studies of old age because of research showing that satisfaction late in life consists of things like maintaining physical and mental health, volunteering and having positive relationships with others. But this isn’t always possible if the body breaks down, if social roles are diminished and if people suffer major losses. “So these people cannot age successfully? They have to give up?” she recalled asking herself.

Wisdom, she has found, is the ace in the hole that can help even severely impaired people find meaning, contentment and acceptance in later life.
