The writer is not from the same religious background as mine and also is of a different generation; he is very definitely of the boomer generation that he claims to be older than. 
Nevertheless he had some interesting things to say and I found myself agreeing with more of what he wrote than I had expected to. 
The book is aimed at people entering the last year's of their life. Perhaps I am fooling myself, but I don't think I'm quite there yet. It is true that physically I am past my peak (I probably could not cycle the mountain bike marathon that I did about five years ago), but I would like to think that I'm still learning new things and having new experiences.
