The magician, mentalist and endurance performer David Blaine has been stunning audiences for decades with his card tricks, illusions, and extreme stunts that challenge both his mind and his body. He’s been buried alive, trapped in ice and suspended in the air while sealed inside a box for 44 days. But in his new series, “Do Not Attempt,” David is the one who's left speechless as he travels the world taking in amazing feats by some of the greatest masters alive — and even trying some of them himself. He talks to Tom Power about his career in magic, what he does to manage fear and pain, and how being a dad has changed the way he calculates risk.
