We're living in science fiction, but we don't realize it.

When I was a kid, I read the science-fiction shelves, and I read the fantasy shelves.

It cannot be said often enough that science fiction as a genre is incredibly educational - and I'm speaking the written science fiction, not 'Star Trek.' Science fiction writers tend to fill their books if they're clever with little bits of interesting stuff and real stuff.

The most watched programme on the BBC, after the news, is probably 'Doctor Who.' What has happened is that science fiction has been subsumed into modern literature. There are grandparents out there who speak Klingon, who are quite capable of holding down a job. No one would think twice now about a parallel universe.

Every intelligent being, whether it breathes or not, coughs nervously at some time in its life.

Time is a drug. Too much of it kills you.
