Sung Fong had two strong obsessions during a long, eventful life: to become a millionaire and to "go it alone." He never married and now, at age 90, has a net worth of more than $10 million, almost all in stocks and bonds. He has no enemies, explaining with a chuckle that he's outlived them all. He has no true friends and no known relatives. With his health failing rapidly, he's added a third goal: to pay no death tax to the government. "Not one cent," he repeats. Can you tell him how to accomplish this last strange goal?
