 I think about an athlete like Alex Honold. He's been into a CAT scan where they've scanned his brain and put images up that cause fight-or-flight responses. In the CAT scan they show no real reaction. He's able to completely block out any kind of fear which is how he's able to go up on these mountains without any kind of harness, rope, no nothing. And I'm wondering is fear an outsized player in this whole ordeal?
