Has suppressing my anger made me unhealthy?

Some people work out their anger by punching a punching bag or doing some physical activity that is draining to the body. Then they seem to think more clearly about whatever topic it is. Holding in your feelings can cause health problems, but exhibiting too much anger is also not good for you or whomever you are taking it out on. I know some guys are afraid to let out the anger cause it would be like letting a tiger loose. Talking with a counselor is also a good option, learning how to open up and discuss things and not to just explode. Stress, it's a killer!
