In my work, I am constantly exposed to the potential for violent behavior (psychologist on an inpatient psychiatric unit). While the actual occurences are infrequent , due to good planning and management, the potential is almost a constant. I find that the anticipation or worry about such an event is worse than the actual fact (when it does occur). The actual events themselves are usually brief and, though upsetting to all in the vicinity, usually end without serious damage to anyone. I find that the 'deeper nature', or 'instinct' takes over at the moment of truth... the fear somehow just goes away, and you do what you have to do to restore control and order. You usually feel drained and shaky afterwards (as the chemical cocktail is metabolized by the nervous system while you are regaining your equilibrium. It is the constant, low-level worry about the potential event that is worse than the event itself. Ironic, but true. And I think this is one reason why a good vigorous workout at the dojo serves such a useful function... it helps us metabolize, on a day-to-day level, the chronic 'subclinical' anxiety we deal with in our fast-paced, and often insensitive, American society of the late 1990's.
