Graham goes one-on-one with one of the world's most renowned rock climbers, Alex Honnold. Known for his heartracing "free solo" climbs - where he ascends 2,000-foot rock walls without ropes or safety equipment - Honnold reflects on his mindset of casting aside fear, visualizing death and the advantages and disadvantages of living in a van. Now a father of two, Honnold also reflects in this 2015 interview about the difficulty of being in relationships as he ascends to the top of his sport.
