That is a good question. Growing up, I read anything and everything; backs of cereal boxes, any and all literature, printing on maps, and so on. And as I was the younger of two boys, I never was able to pick TV shows. Also, I was always reading about reading, which led to picking up longer and more challenging books. I always had a love of SciFi and crime fiction and started seeing those elements in more and more lit, such as Nabakov's Ada, or Doris Lessing's works. While none of the books you mention peak my interest, others like them do, but I will admit to being a prose snob. I would pick up a CK Chesterton work on theology before a dry book on a subject I find interesting.
