Yeah I used to be able to read a 500 page book in a day but that was back before I had anything to do and could just sit down and read for hours on end. Now it takes me about 2 and a half weeks to finish books that long. Of course it also depends on how good the book is. A great book I tend to read faster simply because I get so caught up in it I just can't put it down.
THATS pretty intense. I'm almost the same way. Only I read about 100 or so pages a day, of course, depending on how good the book is.
