When I was younger, I'd read slowly, trying to visualize the setting, keep track of character preferences, look up words I don't know, etc. I'd remember a book well enough to talk about it even a year or so after.
These days, I just skim over descriptions and read as fast as I could while still getting the main plot. I get attached to characters only if the book is really good and savor them during rereads.
Ah thanks for clarifying. Would you not say that reading it slower would be the more enjoyable method? If you're after escapism, wouldn't it be better to engage yourself fully in the plot? At least for me, I find escapism works best when I'm fully immersed in the story's world and characters. What you've described sounds more akin to someone skimming a research paper.
