It may be the 10th often heard question is, how endangered are gorillas or so. So it’s rarely a visitor service. And at one point I was very keen and that was the reason I was previously always quite skeptical that these volunteers, of course, we train them a few months or so but they don’t have the university education and therefore, they can not know so much about animals. And my fear was always that these volunteers would pretend things that are not right. And so my advice for them was always, if you do not know something, tell the people you don’t know. And if you see that a visitor is very much interested, just take the mail address or whatever, and answer it afterwards. But I think nowadays, a zoo needs a visitor service. When you were director at Frankfurt, there were many major events that affected zoos, as you were director.
