What I'm really interested in, as a reader and as a writer, is the idea of the nonfiction book that is not defined by its content, by its "about"-ness. Where you read it irrespective of whether you're interested in the subject.

All sorts of things can keep one awake. But as you get older - this is what the stroke thing really brought home to me - this thing that I never paid attention to: my brain. I've always been conscious that, of course, after a night of getting stoned, my head would feel foggy; if I got drunk the night before I'd be hungover. But that was the extent of my concern about my brain. And then with the stroke thing, it made me realize, "God! That's my main source of income." So it relates actually to your other question about growing old.

The thing that strikes me, from looking at the names so far in the Donald Trump's Cabinet on the foreign policy side, is the one thing that unites them - and that's General James Mattis at the Pentagon, Mike Pompeo at the CIA, even Mitt Romney to become secretary of state - they're all very, very hawkish on Iran.

Nicholson Baker talks about the way in which the most successful nonfiction books are those that can be boiled down into an argument so that everybody can wade in with an opinion without having to undergo the inconvenience of having to read the book itself. The more you can condense it, the better.

For so long I didn't have any kind of readership at all - I'd get published, but not read - the idea of writing for an audience is so anathema to me, it's never bothered me.
