DavidH22...I'm with you in terms of your reaction to this book. Indeed, I've been quite surprised to read how many people have been prompted to laugh out loud. Maybe it is an age thing...I'm in my 70s, and looking to what may yet lie in store. I didn't find a great deal here to look forward to.
As others have pointed out, there have been quite a number of popular fiction books with elderly protagonists of late, often embarking on a journey. Last one I read, and enjoyed, was 'The Hundred Year old Man who climbed out of the window and disappeared'.....Signs of a growth industry perhaps in chick lit for the elderly?! It will be interesting to see if Hendrik Groen does produce the novel hinted at towards the end.
Lest what I've said so far sounds terribly negative, I would say that Hendrik comes over as a sympathetic protagonist. You can't help but warm to him and his friends in the 'Old but not dead' club. They care about each other, they help each other, they raise each other's spirits. You get a real sense too of the care home and its many irritations...the money-saving tactics, the rules, the food, the routines, the hotbed of 'gossip, grousing and gibberish', the effects of ageing and the ever present spectre of death.
Overall then?...I found this poignant and insightful, but not a bundle of laughs.
