I certainly want to continue trying to understand how the global environment functions. The earth as a system is a very complicated one. And to understand it, we need very many disciplines, very many different scientists working together. I want to continue working with my specialty, which is chemistry, with the atmosphere. There is still much to learn about chemical reactions that occur out there in the air, in the atmosphere. So one of my projects now is to really learn more about this pollution that occurs in cities and that is spreading more through the globe. To learn it in enough detail so we can better tackle it, we can better come up with new ways of using energy, for example, that are not so damaging to the environment.

There's still much to do, and I'm not slowing down.

Try to make better antibiotics. I’m not sure we can cure everything, that we can win the game against bacteria, but we can try to control it, to make the appearance of resistance more controllable. We can look for new antibiotics, not overuse antibiotics, not use antibiotics where they are not needed. If possible, if somebody has an idea for something completely new, I would love that.

So a great deal has changed, but we in the Truth and Reconciliation Commission said, “Watch it. You can kiss reconciliation and forgiveness goodbye, unless the gap between the rich and the poor — the haves and the have-nots — is narrowed, and narrowed quickly and dramatically.” So yes, we face very, very considerable problems.

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.

Not really on a major basis. We lost the court case when the Raiders moved, so now you have more or less free agency on the part of franchises. They move from city to city. I thought that was a loss. But I tend to discount extreme praise or extreme criticism. You just have to do what you think is right.

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.

There really wasn’t. That’s one thing I kind of regret. I started reading, and became interested in reading very young. But I read sports books. I read sports pages and newspapers. That’s one thing that I would like to have had that I missed, reading more scholarly books than I did. I was so devoted to sports.

Because everyone has to have an outlet. Otherwise you can get so involved in your job, or any one thing, that you’re not a very well-balanced person, and you’re not happy either, normally. I think it’s very important to take up an avocation. Sports — that was mine. But gosh, it could be music. It could be any number of things that can help give you that escape from your job or your family problems.
