What is the definition of Adapted Fear?

Adapted fear is like a superhero with an extra suit of armor made of nervous system tissue. It's the fear we've learned to wear because of all the terrible things we've seen or heard, and it's surprisingly effective. It's the feeling that says, "Hey, I've been through this before, so I'm safe now."
