As someone in her late 50s and with parents/in-laws in their late 70s, early 80s, I naturally find this a topic of great interest. There's a lot to think about here, and although this book is pretty depressing, it does bring up a number of things to think about - and, fortunately for me, at a stage when I can still plan and prepare in a meaningful way.Although I don't necessarily agree with everything she says, and I think the book is much longer than it needs to be, I think it's a book that's well worth reading. It led me to give a lot of thought to what the experiences of my parents/inlaws are now, what my experiences will or can be in the next 20/30 years, and also to the problems that are inevitably going to be faced by society as a whole - how do we deal with these issues as a society?
