A few weeks ago, my wife asked me to pick up a book for her at Barnes and Nobel. The title of the book is Being Mortal (probably a subject many of us have either written about or a least thought about in our personal life). The author is a medical doctor, Atul Gawande, who has written several books (and is a staff writer for the New Yorker).
Being Mortal is a unique look at humans as we age and suddenly find ourselves in a "frail" condition causing changes to occur in our daily lives. He offers some possible explanations for those changes through observations of people he knows personally as well as his patients. In my opinion, this is a good read for anyone no matter what your current age.
