Well, I was already 51 when I became Director of Frankfurt Zoo, which is in Europe, nowadays, rather old to become director. And my predecessor I knew for a long time and we worked very well together. And I usually visited, he has had his office in our administration building because he remained President of the Frankfurt Zoological Society. And I usually stayed in his office every third week or so to discuss some matters. I never discussed personal matters, but exhibits, animals, and so on, I was always interested to learn his opinion. Not to get orders, but to learn his opinion on different matters. And, of course, I have had a lot of friends among German zoo directors and if I have had questions, I especially approach my good friend Kuntenoke, who was director in Cologne Zoo.
