I think they can but I also think it is open to outside influences like for example, this forum (in which we can get recommendations and learn about new books from others), educational experiences ie. having to follow reading lists etc. Also what we read can be very much of its time and at the time seem really good but then in retrospect seem dated and make us feel we have grown out of it (that doesn't include the timeless classics though). Maybe reading is a thing that reflects phases in our lives when we have more or less time to read and may choose books to fit with those limitations.
Oh dear I've rambled quite a bit here - hope it makes sense.
