how CAN you read too much?

You can't.
I've been an obsessive reader since 2nd grade.
I always feel weird if I don't have something to read.
When I travel, I read the advertisements on the subway going from the hotel to the attraction.
I insist on reading every little caption in the museum, in its entirety, much to the annoyance of my parents (I managed to somewhat avoid this in Mexico only because they gave me half a day in the Museum of Anthropology, then dinner a plane to catch (I would have preferred to go without dinner).
In elementary school, I would spend all lunch and recess reading (still usually spend lunch reading, unless I lack something to read).
In seventh grade, our English teacher had us take journal entries on each book we read. She made an exemption for me after it became clear that I read almost a book a day (I think that my end of the year tally was about 120, primarily because it took me a month to get through the five Susan Cooper books, and a week to get through one equally thin, don't know why exactly).
I have hundreds of books in my room and have taken whole sections out of the library at a time (and cleared bookstores of all books by one author). My parents used to joke that I single-handedly kept the local bookstores in business.
I fill my suitcase with books when I travel, and when I'm without a book that I really want to read, will ultimately get desperate enough to start almost anything (I once started a book on the German problem, for lack of better material).
I've mellowed a bit since middle school, I now read maybe a book or two a week and read a lot of funnies & webcomics, which can't really be called reading. Still. . .
Almost daily I decide to research some topic on the internet (often using Wikipedia, since it leads me in directions I've never intended), simply because I'm curious.
Nope, certainly not possible to read too much.
Some of my fondest memories are of spending weekends, evenings, class trips, and school vacations doing pretty much nothing but read.
Still don't quite compare to this one girl in my school who always navigates the packed hallways during passing period while reading. And there was another like that in elementary school.
