His poigniant, moving and humourous diary has been inspirational. His closing words, written in 2004 in case he became to ill to continue, were:
I will end with a plea. I still have no idea why I ended up with a cancer, but plenty of other cancer patients know what made them ill.
If two or three people stop smoking as a result of anything I have ever written then the one of them who would have got cancer will live and all my scribblings will have been worthwhile.
Farewell Ivan, go in peace.
