Picked scifi and fantasy as that has always been my favourite genre... but really, I read almost everything. I love all fiction, even enjoyed some old romantic adventure type books. I've also read thrillers and mystery. And occasionally I pick up a history book, or any other educational book about whichever subject interests me, as well as I sometimes read religious books (I'm not religious, but I do enjoy reading about it. Helps me with my own beliefs, as well as helps me to have a conversation with religious people)
So really, I pretty much read everything. Only two choices above I never recall touching are self-help and sports.
