I tend to read mostly science fiction books, but also huge numbers of magazines, journals and web sites on science, space and computing. I also read books that give me a glimpse of the world beyond the pampered west, such as "The Wealth and Poverty of Nations" by David Landes, and pretty much anything by Raj Patel.
As a result, my book has a lot of characters that are machines, the science is all hard (I either know or strongly suspect it will work), and the relationship of 1st and 3rd worlds has changed but not improved.
As for the football, well that all comes from the dream: I don't care for the sport, but some of my characters do, and deeply, so I've had to work hard to convey that.
