Right, but you're making it sound like people who don't fear things also don't have any judgement. Just because I'm not afraid of heights doesn't mean I'm going to jump off a building. I'm not afraid of the dark, but I'm not going to walk down an alley downtown in the middle of the night. Not everyone is like the Jackass crew who do things for the rush/money/sex/fame, whatever the consequence. You can live with a fairly anxiety-free life while still making choices that will protect yourself from harm.
