Lucky,
I think Bruce Banner may be overstating the point a little

Basically I've always had a short temper, and never really known why. It's just been a case of my trying to come to terms with it such that it affects my life in a minimal way (such as only getting angry when it is appropriate). I've never been violent towards anything animate when I've lost my temper, but I do appreciate that because of my size (6'4 about 230 lbs in your money) an outburst can make other people who don't know me worried.
I wouldn't describe it as a "red mist" scenario either, I think this is a cop out to try and avoid taking responsibility for your actions when angry. I have enough control to not injure any people when I lose my temper (except maybe myself) but when I'm angry it seems that's the extent of my control until it passes.
I understand what makes me angry, but as I've said before, anger bypasses the rational part of your brain. You astutely point out that learning to deal with anger is important. More important is learning how not to become angry, see the link I've posted earlier. I'm working on this, and it's not going to happen overnight. What I have found is that for me, it takes a conscious effort not to get angry about something, and most of my triggers centre around one of two things:
My expectations of myself
My expectations of the world around me
When I, or the world, don't align with these expectations, frustration occurs, if this mismatch continues, then I get angry. It's a long and involved process, trying to force my higher brain to kick in at these times and rationalise to myself and prevent the anger "taking hold".
I can say one thing with certainty. I don't enjoy being angry, that's why I've spent most of my life trying to reduce the impact that anger has on my life in general, and my bowling in particular. But it's not an overnight thing, and people only see a snapshot of me being angry, they rarely see what I was like 15 years ago, 5 years ago, last time I was angry, and they will likely not see me in 2 years either when i hope it will be better again.
I hope this provides a little insight...
