Dont get mad

Anger is something that everybody has but why is it that when people get mad they have a trouble controlling it. You think the older you get the easier it would be to control and that is not the case. It seems the older you get the easier it is for you to get mad I am guessing that is something that comes with the territory of getting older and the consequences get greater with the age. When you were a lil kid you were able to throw a temper tantrum and threw things but the older you get you gotta out that anger into something productive or else you will release it in other was and you will end up hurting someone or something. You see that the ones that you care about the most are the ones that can make you mad easier than easier than anyone else that you can think of. The ones you care about can drive you to kill a lot faster than the ones that you do not even know just because you expect more from them and you have to find a way to get back at them. Somebody please tell me is this true or not and why?
