Dana Jennings, who gamely did an impromptu rendition of The Honkey Tonk Blues in the greenroom, while a guest on Episode 6 of Titlepage, was diagnosed with prostate cancer in early 2008. He's been writing a very raw, and sometimes painfully honest weekly blog about it in the New York Times Science Blog.

Two springs ago, his son Owen's liver failed. Owen too shares his experience in a blog. Both Dana and Owen are also the topic of a Times video.Very touching, very inspirational.
