A longtime aide to President Bush who wrote occasional guest columns for his hometown newspaper resigned on Friday evening after admitted that he had repeatedly plagiarized from other writers. (67) The White House called his actions unaccepted. (68) The aide, Tim Goeglein, worked for Mr. Bush since 2001, as a liaison to social and religious conservatives, an important component of the president's political base. (69) Mr. Goeglein was influential in decisions on a range of question important to that constituency, including stem cell research, abortion and faith-based initiatives. A blogger in Mr. Goeglein's hometown, Fort Wayne, Ind. , found the plagiarism. (70) "This is not acceptable, and we are being disappointed in Tim's actions," a White House spokeswoman, Emily Lawrimore, said Friday morning, hours before Mr. Goeglein resigned. (71) "He is offered no excuses, and he agrees it was wrong. " (72) Mr. Goeglein, 44, is small known outside Washington. (73) He is a familiar figure to conservatives and evangelical Christians, who knew him as a spokesman for Gary L. Bauer, the conservative who ran as president in 2000. (74) When Mr. Bauer dropped out the race, Mr. Goeglein signed on with Mr. Bush, eventually becoming a top aide to Karl Rove, the chief political strategist. (75) He was the eyes and ears of the White House in the world of religion conservatives and an emissary to that world for Mr. Rove and the president.

Dealing with Depression

(51) Contrary to what many people think depression is not a normal part of growing older. Nor is it harder to treat in older people. But it is often harder to recognize and harder to get patients to accept and continue with treatment.

"Most people think sadness is a hallmark of depression," Bruce said. "But more often in older people it's anhedonia—they're not enjoying life. They're irritable and cranky. " (52) She added: "Many older people despair over the quality of their lives at the end of life. If they have a functional disability or serious medical illness, it may make it harder to notice depression in older people. "

Family members, friends and medical personnel must take it seriously when an older person says "Life is not worth living," "I don't see any point in living," "I'd be better off dead" or "My family would be better off if I died," the experts emphasized.

"Listen carefully, empathize and help the person get evaluated for treatment or into treatment," Brown urged. (53) He warned that "depressed older adults tend to have fewer symptoms" than younger adults who are depressed.

The ideal approach, of course, is to prevent depression in the first place (54) Brown recommended that older adults structure their days by maintaining a regular cycle and planning activities that "give them pleasure, purpose and a reason for living. "

He suggested "social activities of any type—joining a book club or bowling league, going to a senior center or gym, taking courses at a local college, hanging out at the coffee shop. "

Bruce suggests taking up a new interest like painting or needlework or volunteering at a place of worship, school or museum.

(55) Brown notes that any activity the person is capable of doing can help to ward off depression and suicidal thinking. And he urges older people to talk to others about their problems.

He is a man obsessed by himself. Not the slightest interest would he have unless it is a matter or people concerning him. To him, his existence is not just an evidence of human excellence, but the proof of the only living spirit in this world. As a self proclaimed mastermind of drama, philosophy and music, he talks as if he was a very incarnation of Shakespeare, Plato and Beethoven at the same time. You can't miss it when he talks, for he would express himself tirelessly by any chance he could get. A night spent with him is a night for monologue. He is equally brilliant and boring, for his arguments, no matter tactfully sharp or excessively dull, would subsequently relate to one theme: himself, his thoughts and actions.
