OMAHA, Neb. -- Warren Buffett, 83, practically runs down the hallway of his simple little 14th-floor office to greet me. Not his secretary. Not his receptionist. Warren Buffett himself.
Buffett has a young heart and young ideas, but today he is practically bouncing off the Notre Dame-style "Invest Like A Champion Today" sign over the door to his office. He offers you a Coke, possibly because his Berkshire Hathaway holdings is its largest stockholder at 9.1 percent.
