Recently, I dragged Mrs. CFS to a documentary called Free Solo, the one featuring Alex Honnold, who is, quite simply, an athlete without peer, maybe the greatest ever.
For those who don’t know, Honnold, 33, is a free soloist, which means he climbs sheer rock walls with no ropes, no crampons, no carabiners, no parachutes, no jetpacks, no nothing to arrest his fall if he makes even the teeny-tiniest mistake.
