Do you read books “meant” for other age groups? Adult books when you were a child; Young-Adult books now that you’re grown; Picture books just for kicks … You know … books not “meant” for you. Or do you pretty much stick to what’s written for people your age?
I don’t think I ever cared all that much about age groups.
Not that I think I started reading adult books extremely early; I guess from my early teens or so. (I think my mother rather encouraged it; she read a lot herself.)
I still enjoy reading or re-reading classic children’s books or young-adult books from time to time (even at age 55+). I can’t say I have kept up to date with that kind of literature from more recent years though – except for the Harry Potter series and a few others in that genre.
On the other hand, I can’t really claim that I’ve been able to keep up to date with literature written for my own age-group either!
