I think the most important thing is to keep active, and to hope that your mind stays active.

I want to change awareness.

One thing I had learned from watching chimpanzees with their infants is that having a child should be fun.

I cannot remember a time when I did not want to go to Africa to study animals.

The chimps' way of aggression is quick and brutal. I compare them to gang attacks.

The least I can do is speak out for the hundreds of chimpanzees who, right now, sit hunched, miserable and without hope, staring out with dead eyes from their metal prisons. They cannot speak for themselves.

Other people have talked about chimpanzees being a window into the past, which I suppose is true, in a way.
