As a journalist, one tends to think there's nothing off limits - Peter Jennings

Finally this evening, a brief note about change: Some of you have noticed in the last several days that I was not covering the Pope. While my colleagues at ABC did a superb job, I did think a few times I was missing out. However, as some of you now know, I have learned in the last couple of days that I have lung cancer. Yes, I was a smoker until about 20 years ago, and I was weak and I smoked over 9/11. But whatever the reason, the news does slow you down a bit. I have been reminding my colleagues today, who've all been incredibly supportive, that almost 10,000,000 Americans are already living with cancer, and I have a lot to learn from them...and "living" is the key word. The National Cancer Institute says that we are survivors from the moment of diagnosis. I will continue to do the broadcast, on good days; my voice [laughs] will not always be like this! Certainly, it's been a long time, and I hope it goes without saying that a journalist who doesn't value deeply the audience's loyalty should be in another line of work. To be perfectly honest I'm a little surprised at the kindness today from so many people; that's not intended as false modesty, but even I was taken aback by how far and how fast news travels. Finally, I wonder if other men and women ask their doctors right away, "Okay, Doc, when does the hair go?" At any rate, that's it for now on World News Tonight. Have a good evening; I'm Peter Jennings. Thanks, and good night.

On 9/11, those of us who do the jobs that I do, flew without a net for hour and hour and hour after end. And then you hope and pray that you've had the experience to be up to it. Because then you're editor, analyst, reporter, correspondent, ringmaster, the whole thing.

"I'm a little concerned about this notion everybody wants us to be objective," Jennings said. Jennings said that everyone — even journalists — have points of view through which they filter their perception of the news. It could be race, sex or income. But, he said, reporters are ideally trained to be as objective as possible. "And when we don't think we can be fully objective, to be fair."
