Conventional wisdom regarding The Lord of the Rings posits a subtext of J.R.R. Tolkien's disgust with the effects of the industrial revolution and rejection of it for the agrarian England epitomized by the Shire. Found outtakes from a 1968 BBC documentary about Tolkien reveal that the author was not as dismissive technology as popularly surmised. Among other things, in one outtake he says he's fond of driving.
Alex Honnold is a fearless free climber who scales sheer walls without ropes or companions. That's him in the photo at right doing something I would not. He is what's called, by a certain set of neurologists, a "super sensation seeker"—someone who deliberately puts himself in extreme situations that would terrify a normal person. Neuroscientists once put Honnold in an fMRI and showed him images that generate a strong response in the amygdala of most people; his amygdala did not fire at all. He says he has experienced fear on climbs, but may use visualization to reconsolidate memory, turning a terrifying experience into a desirable one. Neat trick, if you can do it.
Speaking of the amygdala, there's a disease called Urbach-Wiethe that damages it. Among the behaviors that result is, yes, absence of fear, but also an odd sense of personal space. For example, there's an account in the literature of one person with the condition was comfortable standing nose-to-nose with strangers, staring into their eyes, while talking. I believe I've met this person.
