Fear

I'm watching Iron Man 3--I won't spoil it for a the six of you who are still planning to see it, but at its core is an investigation of fear.

How can others manipulate us, pulling us from our logic to our base terror?

Do we fear the things that actually hurt us?
How can we overcome fear, or at least keep it from paralyzing us?

And what hope is there for those of us without a fancy metal suit?
