Whew, what a question — but I've wondered about that myself. At this point I'm much more concerned about running out of time before I get to do All The Things, and I'm relishing my days more fully than perhaps I ever have. But who knows what might cause life to lose its savor? I know it's not up to me, but I do cherish the hope that at the very end, I'll feel satisfied with the journey I've taken.
