It's kinda weird to see the view of someone else. I can't imagine going to bed without reading at least 50 pages/screens of a book. I've always got a book on the go and if I'm likely to be waiting anywhere for a period of time then I'll take a book (now the reader) to pass the time.
I fade in and out of interests myself all the time along with forums and websites and all sorts of things. For me though, reading is always there. Collecting books and reading is just something I've never considered to be an interest but more of a background to everything else. It's always there but I don't notice it.
