In most cases though anger can't be helped and is in some cases understood or even expected.
I try not to be angry and most of the time I'm not but I'll admit that I tend to hold onto things far too long, like if someone wrongs me I'm a little quick to label them as my enemy and I tend to brood on what they said and/or did to me slightly longer then I should
You know, it's funny that you mention this, Will. These are some true words, and I think it's hilariously ironic. Usually people who are bigger are stereotyped into being angry or brutes. It's like when people are behind the wheel of a car and feel powerful because they're controlling several tons of roaring steel, and are prone to road rage, or people who are computer savvy and like the quasi-anonymity the internet provides on a site like YouTube and therefore feel entitled to say whatever they want with little to no repercussions.
But like I said, you're right, but in a different sense. Yes, anger is a natural emotion and it can be a healthy release, if done right (I.E. meditation, calmly voicing your displeasure, breathing exercises, etc.), but on the opposite side of the coin it can not only kill people you love emotionally or literally, but yourself as well. Unfortunately, not a lot of people like to heed my advice and instead think that acting like a savage ape or Godzilla will help, but the repercussions can and will come back to bite them on the butt.
On the matter of what things make people blow their stack, losing it over trivial things is ridiculous. I understand if someone had a rough day and there's only so much BS they can handle before something must be done, but I believe you and I are referring to people with hair-trigger tempers, where the person has a rage repository always filled up and are just waiting for someone to just so much as glance in their general direction. Life's too short to live a life of rage. Save it for the bigger things; the things that matter.
As I've said, there's healthy ways to extinguish anger. If it's a big problem, use the anger as a motivation to get the problem rectified, especially if it can be fixed. Exercise helps as well, like maybe a punching bag or running (I personally enjoy the latter). Now if only more people could see this, maybe, just maybe, life would be a little bit better and a little more fair.
I'm kind of the same way, but overall I'm a chill guy. Usually it's computer problems that cause me to get a bit miffed (Unless I can fix it), but otherwise I don't get pissed easily (Pardon my French)
But like I said, anger is a perfectly normal feeling, it's just how you use it. ^_^
