You mention the "film", is that the Children of Men, or is there a film of "The Ambassador".
I read the article you quoted, but realised I would need to print it off to read more closely.
When I got to the point he makes about most people, after recovering from work-related exhaustion, wish to act, it reflects my current situation.
I will be seeking out the book it comes from, possibly from the library.
Thanks for this extremely interesting post.
