After 30 years in nursing, Debbie Volker has learned if there's one thing people want to do on their own terms, it's die. She tells the story of a weakened, dying woman who just wanted to have her Christmas tree decorated. The woman hung a few ornaments each day, succumbing to cancer a few days before Christmas. But the tree was done. Another patient's request was to be transported by air from Houston to West Texas so he could see his cattle one last time.
