I still regularly read New Scientist to try to keep up with quantum theory and cosmological discoveries and so forth. And I read National Geographic—that’s not a plug.

One of the saints in my life is this woman named Imogene Hill, who was a fourth-grade teacher who taught this advanced class. She got hip to my whole situation in about a month and kindled a passion in me for learning things. I learned more that year than I think I learned in any year in school.

I have also benefited from teaching; as I try to explain my views to students with critical and open minds, I find myself continually being challenged to go back and rethink ideas. I now see teaching and research as complementary, mutually reinforcing activities.

Science is about curiosity-driven learning, and unless you are curious, you will never find science exciting.

Oh, over the years, there are so many. One would be the man — I wanted to take his job away some day — Paul Zimmerman, sports editor of the L.A. Times. Jim Murray is writing for the Times now. Red Smith. I had the honor of meeting Grantland Rice way back when I was at the University of San Francisco. When we played New York in football back in 1951. Just a lot of good sports writers became friends of mine. And I respect them a great deal.

I think to a certain respect, yes. But also, you try to follow the best guidelines you have, the constitutional by-laws. You have to interpret them from time to time, but in the final analysis, in some instances, it would be a gut reaction. But a gut based on preparation and study. Not just a fly-by-night gut reaction.

It’s difficult. You really have to do it as best you can. Because your family is important too. You can’t be so totally absorbed that you are not involved in their activities as well. So, I tried to divorce the two as best I could.

You can’t make decisions based upon whether it will be popular or not. You have to make decisions based on whether they’re right.

I have never really studied them very much. I think that I was proud of — not just what I did — but my staff played obviously a major part, did in popularizing the sport, with the early promotional activities of NFL Properties, merchandising, NFL Films, all the work that we put on the Super Bowl to make that a top attraction. All those things, I feel very good about, but I think they played a big part in popularizing the league.

Because of my love for sports, and the nature of my job, it was pretty intense for 30 years, and you have to be sure. I would take it home. My wife would know when things were tight, and she would hear me get up in the night, and walk around and sit and think. It’s not something you can leave at the office.
