I always wanted to be a surgeon, because I had a lot of admiration for my father, who is also a surgeon. I also wanted to be a heart surgeon. That was motivated by the fact that my young aunt, a sister of my dad, died in her early 20s of a correctable heart disease.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
