Once you've spent a week out in the middle of the woods alone with nothing but a lighter, a backpack with extra clothes, a fork and a sharp ass knife fear is simply a nervous feeling you really tend to forget... (no cellphone, no flash light, NO ELECTRONICS.)

Of course there's worse situations you could be in but it really puts your instincts to the test. Helps you realize what you are capable of when your life is threatened.

So I decided to try it. I'm still alive and trust me, what they say is true. Natural instincts are undeniably the most powerful force on this planet. (except gravity)

Do I "fear" what someone thinks of me? Short answer, no.

Fear isn't the word for it in my opinion. I think concern would better suit what you're trying to say. Everyone has some sort of concern about thier personal image within others. Not everyone really responds to that concern, but it's naturally there whether they like it or not. It's an instinct...
