Stress addiction

Nature 
A number of activities and situations increase the flow of the brain's opiates, creating a sense of euphoria or excitement. One of these is stress. When a person is in a stressful situation endorphins are produced reducing pain and creating a sense of joy. Endorphins are much like morphine in their effect. Sports people, religious practitioners and military personnel use this effect to enhance their activities.
