Anger

Here's another one I'm a little nervous about the result (before seeing it)...

You Are 50% Angry

Generally, you are not an angry person. But you're easily frustrated and enraged. You have one heck of a temper. And because of your anger, you [sometimes] tend to feel resentful and even spiteful. You already know how to quell your anger. You just need to do it more often.

How Angry Are You?

Pretty accurate. I'm actually surprised at how low this is...

I have said that I'm much like The Hulk: you wouldn't like me when I'm angry. And I find it very difficult to quell, which is why that last line isn't italicized.
