Fantasy vs. Science Fiction

when you're hungover and demons are running around the room, that's :smile18:, but when green little men (probably aliens) appear, that's life.

I don't really like fantasy, although there are some things I enjoy reading.
As for science fiction and life, 100 years ago, only science fiction writers wrote about space travel, and now everyone who wants to can fly. 50 years ago, heart surgery was science fiction - now it's a reality. And there are many similar examples.
