[Aerkuld]

I watched this the other evening, on Hulu if I recall. Personally I thought it was extremely well filmed and did a good job of exploring the man, his methods, and his reasoning. I disagree about him being born with no sense of fear. Although the brain scan showed he has little activity in that area compared to most people, I thought the point was that he had trained himself to not be fearful of things he could control rather than overcoming his fear. The difference is subtle, someone can overcome their fear by doing something that they know is risky, but dismissing the fear and doing it anyway. He isn't doing that. He's planning, practicing, preparing, rehearsing in order to remove the element of risk. He isn't fearful because there's very little left of which to be fearful.
There were clearly times in the film where he demonstrated some fear - the uncertainty of a foothold for example. Also, the fact that he spent ten years thinking about this climb, planning, and preparing for it. If he wasn't fearful he'd have just gone ahead and tried it, but he didn't. He's meticulous, and that was the whole point of the film. For him this isn't about the thrill. This climb was, as he said, about perfection. There was one segment in the film where he was talking through the climb to the camera. He knew that rockface like the back of his hand. He knew exactly where his hands and feet would be at any point, knew where they were going next, and where they went after that. He had memorized every single foot and hand hold up the entire route. THAT is what excited him about this challenge. Practicing to the point where he could climb it in his mind, almost to the point where he could do it blindfold. That was his thrill, not the risk.
If you want to accuse the guy of not being normal, fine, but he's 'not normal' because of his extraordinary ability to focus himself - absolute dedication to a project.
I can't help but admire the guy for how amazingly focused he is. He doesn't need fancy clothes, houses, cars, or bags full of money. The fact that he seems perfectly content to find happiness within himself is amazing.
