I didn't know what Facebook was, and now that I do know what it is, I have to say, it sounds like a huge waste of time.

I'm in the middle of my sixth book, which is about animals at the Los Angeles Zoo.

I had to make a major decision with myself because I just don't think you can do both: try to have a baby career and raise it and have a baby baby and raise it. And to try to do justice to either one. It was a very conscious decision on my part not to have children - which I have never regretted.

It's been phenomenal, but everybody keeps congratulating me on my resurgence and my big comeback. I haven't been away, guys. I've been working steadily for the last 63 years.

You know what the problem that animal activists sometimes have? They only concentrate on the heartbreaking things to the point where the general public thinks, 'Oh, here comes those animal folks again and I'm going to hear all the things I don't want to hear.'

I think everybody needs a passion. Whether it's one passion or a hundred, that's what keep life interesting.

I enjoy being busy, I really do. Remember, I'm the stub end of the railroad. I have no family, so I'm not taking busy time away from people that I should be spending it with. So I'm just relaxing and enjoying it.
