As far as the Carter Center's concerned, I would like to see guinea worm completely eradicated before -- before I die. I'd like for the last guinea worm to die before I do. ... I think right now, we have 11 cases. We started out with 3.6 million cases. And I think we have two cases in South Sudan and one case in Ethiopia and one case in Mali and seven cases in Chad. That's all the guinea worms in the world, and we know where all of them are. So obviously, that would be my top priority.
