“In my life right now, I’m eighty. There is so much left to do. So I would like to go back and give myself a bit longer, but as it is, I don’t know how long I have to live, but certainly it is that every year takes me closer to the end, whenever that end is. And so there is this feeling of desperation - there’s so many places I want to go, so many people I want to talk to, and so many hearts I want to reach.”

— Jane Goodall, Human documentary
