I have just finished reading a very good book. It's title is Being Mortal and it's written by Dr. Atul Gawande, a most wise surgeon. I recommend it highly if you are an elder or even more importantly, a member of the generation with living parents and their own adult children. (I know there is a name for this generation but I can't remember it)
I think it's important that, if possible, all three generations read this book. It's about dying. But it's also about living to the end and being in control till that time. It's about ending with joy. Oliver Sacks, himself recently dying, praised the book. I think quite highly of Dr. Sacks and his books are always worth reading.
Look up the title of the book, Being Mortal, on Google and read some of the descriptive reviews for a 'feel' of the book. I think you will find it to be a book for your library. Mine is; as soon as my family finishes reading it.
