Minnesota, USA (Star Tribune): David Nelson got the bad news about his wife in December 2005. He just didn't know it. For three months, the Nelsons met with doctors at North Memorial Medical Center, but they weren't aware Mary Ann was dying of cancer. In fact, they thought she was doing well enough in her battle with the disease that she could go to her retirement party. So they were stunned in March 2006 when her oncologist abruptly put an end to their hopes -- and their request -- with a terse note saying, "We can't cure the cancer."
