Building Resistance to Stress and Aging: The Toughness Model
by Richard A, Dienstbier
"As we engage in toughening activities, physiological toughness develops in response to various genes being turned on or off—sometimes temporarily, but sometimes for a lifetime. Those physiological events lead to modifications of our neurochemistry and the development of various neurons and structures within our brains. As we become physiologically tougher, those modifications lead, in turn, to positive psychological and mental outcomes that include emotional stability, enhanced energy, more efficient cognitive functions, fluid intelligence, and even self-control... Once toughness begins to develop, the experience of enhanced mental and physical energy, and of sustained mental abilities, allows us to optimistically approach life’s various challenges. Confronting those challenges toughens us even more. Thus once we begin to toughen we experience an upward spiral where toughness leads to choices that in turn continue to toughen us."
