Real danger is nothing more than just living. Of course, living is merely the chaos of existence, but more than that it's a crazy mixed-up business of dismantling existence instant by instant to the point where the original chaos is restored, and taking strength from the uncertainty and the fear that chaos brings to re-create existence instant by instant. You won't find another job as dangerous as that. There isn't any fear in existence itself, or any uncertainty, but living creates it.
