Jane Wagner’s words, “reality is the leading cause of stress amongst those in touch with it,” highlight the dire truth that day-to-day life is stressful and, all too often, traumatic.

We know that many older people consider severe adversities in their early life to be "just part of life," implying very limited or neglected utilization of professional intervention (Hiskey & McPherson, 2013).
