What you describe is how I was when I was younger, too. I read everything, I read pretty fast, and I could read for hours on end. That is no longer the case at all, and I'm uncertain when or why it changed so drastically. (The "when" is tough to pinpoint because for much of my early 20s I wasn't doing much reading, and it's possible that the "why" is related to some change my brain underwent during/because of that.)
