 Well, Alzheimer's can progress very rapidly after it's diagnosed. As I said, I've dealt with a lot of people. You could see them, and six months later, they're totally different people. It's really sad because when it comes to a relative, you lose them before you lose them. You know what I'm saying? It's time to keep up the good work. Yeah, you're so right. Ralph, thank you. I appreciate the call.
