On the Rolling Stone's website Keith Richards said of their long career,
It's still too early for me to talk about the Stones' legacy. We haven't finished yet. There's one thing that we haven't yet achieved, and that's to really find out how long you can do this. It's still such a joy to play with this band that you can't really let go of it. So we've got to find out, you know?"
