How do I say something like, "As I am growing older, I think more and more about the past."?
Especially the "as I am..." part, which has the meaning of "while" but over an extended period of time.
edit:
I am aware of ながら but don't know if it would be valid for me to say
成長しながら、もっともっと子供の時を考える。
(As I am growing older, I think more and more about my childhood.)
