So when you do your family tree and Margaret Cho does hers, and... Wanda Sykes and John Legend... we're adding to the database that scholars can then draw from to generalize about the complexity of the American experience. And that's the contribution that family trees make to broader scholarship.

You can say I had a severe case of 'Roots' envy. I wanted to be like Alex Haley, and I wanted to be able to... do my family tree back to the slave ship and then reverse the Middle Passage, as I like to put it, and find the tribe or ethnic group that I was from in Africa.

The more you learn about yourself and your family tree, your self-esteem goes up. They will learn archival skills, historical analysis and science skills. You learn all this in the most seductive way, and that is through learning about yourself. Who doesn't like talking about themselves? It doesn't seem like science or history, it's just fun.

The story of the African-American people is the story of the settlement and growth of America itself, a universal tale that all people should experience.

I think that is what we do by preserving and telling our stories. If you don't tell your stories, other people will tell their story about you. It's important that we nurture and protect these memories. Things change. Existence means change.

The thing about living in a village at the foot of a mountain is that the world for you becomes, without thinking about it, self-contained. People are of two kinds, really: from the Valley, and from Elsewhere.

My father lived to be 97 and played bridge every day up to the end, so I've got a 50 percent chance of living a long life like him.
