When Howard Rutledge was shot down over Vietnam, he prayed for the first time in 20 years, but, believe me, it didn't take another 20 years for Rutledge to try prayer.  He started praying and praying hard.  "When one is dying from starvation," he later wrote of his ordeal, "a bowl of sewer greens is a gift from God.  Before every meal during my captivity," he said, "I offered a prayer of thanks."
