Matt recently went to dinner with a bunch of poker friends. They decided to play credit card roulette for the $2,000 dinner tab -- everyone tossed their credit cards into a pile, and the server picked one at random to charge. Matt's card got picked, and the only reaction it elicited from him was an annoyed chuckle. And it wasn't because $2,000 meant nothing to him. It's just what poker does to you. You get desensitized to losing huge gobs of money due to random chance.
