Brandon Davies' life is all about risk. A guru of global financial markets, he's on the boards of two new banks. Until recently, he headed an international association of risk professionals. He runs a trading operation, using his own money, just for kicks. Risk, he says, is how we learn and grow as people. We should embrace it, not avoid it. At least that's what he said last summer, when producer Sean Cole spent a few days with him in London. Then the global financial system collapsed. Sean took a deep breath and called him back.
