It is always sort of unnerving to hear from people who've read my books. I'm not reading any of the reviews and most of my friends haven't read it - they bought it, which is all I frankly care about, but they haven't read it.

As with editing, I think my strength as a writer is structure. It's not a skill that's much discussed when we discuss fiction, or not as much as language or character development anyway, but it's the first thing I determine before I begin writing - not just books, but anything. I think I know how to pace a narrative well. I think I'm aware of repetition, that I try to create different kinds of sentences as often as I can. Those are all things I learned from magazine editing.

When you're 21 you think, "Old people sound like this. Old people think like this." I don't think my ideas about aging and about eternal life changed that much, but it became more poignant to me as I did get older and I could better imagine, as you sort of inch closer to death every day, why legacy, more than aging, becomes important to people.

My father collected turtles when he was young. My parent's wedding album, there's two pictures of them getting married and the rest are just pictures of turtles. I remember they had Galapagos tortoises that they had somehow imported illegally and a bunch of other turtles too. I like the animals themselves. They're so self-possessed and self-contained and there's something wise and mysterious about them. I also like that they are prehistoric animals.

Health insurance, which is exceedingly difficult to secure as an individual in New York. Obamacare, while certainly better than nothing, is pretty awful, and if you have a complicated health history, as I do, you need premium insurance, which means private insurance. The challenge, though, is finding a company that will give you the privilege of paying up to $1,400 a month for it. When I didn't have a job, I spent more time thinking about insurance - not just paying for it, but securing it in the first place - than I wanted to.

I was fortunate to be at that school in an era in which encounters between students and teachers were encouraged; there were a number of teachers who lived on campus, and they'd regularly invite students over for dinner on the weekends. I hope it's still like that: being treated seriously by an adult you admire is a great gift. Children, like adults, want respect - but it's only when you're older that you realize how few people actually extend it.

If you start asking how do we make life meaningful and life never ends, then you get into sort of these terrible sort of metaphysical quandaries and it gets really, really bleak looking.
