Anxiety is a physiological state characterized by cognitive, somatic, emotional, and behavioral components (Seligman, Walker & Rosenhan, 2001). These components combine to create the feelings that we typically recognize as fear, apprehension, or worry. Anxiety is often accompanied by physical sensations such as heart palpitations, nausea, chest pain, shortness of breath, stomach aches, or headache. The cognitive component entails expectation of a diffuse and
certain danger.

• Almost all men are over-anxious. No sooner do they enter the world than they lose that taste for natural and simple pleasures so remarkable in early life. Every hour do they ask themselves what progress they have made in the pursuit of wealth or honor; and on they go as their fathers went before them, till, weary and sick at heart, they look back with a sigh of regret to the golden time of their childhood.
