 It's called the Gerald Lynn strain. It still is. And he thought that was a nice thing, but it wasn't something. It was just one of those facts of life. Gerald Lynn told us after he was done with mumps, he was just off to the next thing. And, you know, he carried around a list at times. This list he kept in his pocket. A list of diseases that still had yet to be conquered. And I think it was a reminder that, you know, for him, his work would never be done.
