I found Frank Bruni's couple of columns in the NY Times about his sudden vision troubles moving. At book length, though, this topic doesn't work for him. For one thing, there's too much filler that's not about him - he had only about 100 pages of good, relevant material. Secondly, I didn't notice it in 1000 words, but at book length I couldn't help seeing that Bruni processes information through his intellect and not through his emotions. There's not much feeling expressed in the book or that comes across to the reader. On such a personal topic as disability and mortality, that makes him seem remote and unemotional.
