In the 1950s that tug-of-war between the expectations of behaving normally and the limitlessness of thinking freely produces some very strange characters.

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'm an indulgent writer - I'm not sure, however, that's something I'm interested in changing. Writing should be indulgent: you should take big risks on the page, you should make big mistakes, you should be excessive at times. I let myself do as a writer what I probably would be less likely to allow as an editor.

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.

I know I'm a better editor than I was when I began, twenty years ago. I'm less scared of the text, I'm less scared of the writer, and, crucially, I no longer believe that I have to leave my mark on every story.

I wanted to write about the time when science became modern, around the 1950s. Right after physicist J. Robert Oppenheimer, science started being so politicized and used as such a political weapon. When my father, who is a scientist, tells me about those years, I get a competing portrait of people who were expected to behave normally and be decent respectable members of society and who were also allowed this freedom to think in big and expansive ways. Now, when you think about people who work in labs, they're allowed to be socially inept in a very fundamental way.

When you never leave the literary biosphere, you forget how few people actually read books, and that in turn makes you start overestimating both your ability to make money and your relative renown, which has dangerous consequences: the first means you may end up in debt; the second means you may end up a horrid bore.
