David Blaine begins his visit to Here's The Thing by pushing an ice pick through his hand. He tells host Alec Baldwin that he began training his brain to overcome pain at a young age. Blaine grew up in Brooklyn, an only child with a single mother. He spent many afternoons at the local library and he channeled his isolation and loneliness into an early fascination with magic. Today, Blaine is an acclaimed street magician and sleight of hand artist, and also performs staggering feats of endurance: He has balanced on a 100-foot pillar for 35 hours; hung in a transparent box for 44 days; held his breath for more than 17 minutes at a time. He calls it magic, but says his work is mostly about mental toughness. "Anything I do, anybody could do... It's playing with that line of how far can you push yourself before you crack, live in front of an audience, that I'm intrigued by."
