Instead of love, I can also imagine that it's about growing up. "A thousand years" as a picture for the jump you make inside your mind. The question "you ready?" has something more final then. But it "takes you" anyway as the life goes on until you can't resist anymore. I won't go into a detailed description like Solarius did, that's way too hard for me in english, so just read his text again and think about it with this theme ;).
Damn, you can call me "Master of double posts"...
