In all honesty, to hijack the post, First Person Shooters. An hour of Team Fortress 2 or Guild Wars and all my anger aggression and hostility is done and gone. Everyone gets angry. Everyone needs an outlet that gives you a way to vent frustration and anger that will let you refocus and find your calm center. And this is normal. Repressing anger, sorrow, joy, any emotion leads to poor behavior. I think that it is important to teach people that emotions are not... is bad the word I'm looking for here? We all get sad, angry, happy, etc. It is how we deal with those emotions and how we deal with the world outside of our control that matters. You also cannot control other people; you use your character and virtues to define your reaction to them instead. By reacting this way you set an example for others to follow and hopefully they treat you the same way you treat them.
