Chimpanzees can be quite political.

I've got different ideas of complete happiness. But one is being by myself out in a forest, completely happy. Another is walking with a dog in some nice place. And three is sitting around preferably a fire, but not necessarily, and drinking red wine with friends and telling stories.

I want to change awareness.

Chimps act the way they feel unless they are afraid of reprisal if they do so. But that doesn't apply to humans.

I believe that the tragedy [like terror attack] that's caused so much grief and suffering to so many thousands and thousands of people has also served as a call to action, because many people now are re-examining their own value systems, and the churches, temples, mosques and cathedrals are packed to overflowing for the first time in years.

You know the old expression "We haven't inherited the world from our parents, we've borrowed it from our children"? Well it's just not true. We haven't borrowed anything.

The person who has the most influence on me is my mother. Think of life as a flight where we fly higher and higher. If I were a bird that needs feathers to fly higher, I would regard my mother as my strongest feather.
