I was really interested in the fact that blacks have high blood pressure, heart disease, and diabetes at a higher percentage than the rest of the population. That didn't stay very aggressively in the book, but that's how it started. I began to document these moments as support for this other thing I was thinking about, and then the moments themselves began to take over.

I think having a term for a condition that is prevalent is useful, because then people understand it as something not particular to them. It allows you not to ask the question, "What's wrong with me?" and begin to ask the question, "What's wrong with this place that I'm in?"

I was at Yale and I said to the poet Elizabeth Alexander, "I'm interested in the ways in which black health seems precarious in the United States." She introduced me to the term "John Henryism." And then I went back and researched it and understood that, woah, this thing I am thinking about is actually a condition that's named.

I think words are the thing that either triumphs for you, in your desire to communicate something, or fails. I love language because when it succeeds, for me, it doesn't just tell me something. It enacts something. It creates something. And it goes both ways. Sometimes it's violent. Sometimes it hurts you. And sometimes it saves you.

You want to belong, you want to be here. In interactions with others you're constantly waiting to see that they recognize that you're a human being. That they can feel your heartbeat and you can feel theirs. And that together you will live - you will live together.

When you achieve it fully, you create something that's transparent - that people can move into and through their own experiences. As a writer, I don't want people spending time thinking, "What does she mean?" I want, in a way, my text to go away. So that the words on the page become a door to one's own internal investigation. It's just a passage. If the work does its job, it just opens.

If you make a mistake, then you should own that mistake.
