I voted SF & F but only because these are the genres that I read most.
However, SF & F only make up say 30-40% or so of what I read.
I also read Historical fiction and non fiction, Mystery and Thrillers, Science and Political non fiction and Humour.
I read other types of books as well but not in such numbers that it makes any difference (say once or twice a year I will read a book that does not fit in any of the above).
I'm one of those people that re-reads books, in some cases a a lot of times (I have "favourite" books and series that I must have read 7-8 times).
