Optimistic Aging is a very thorough review of an incredible amount of research into the science and sociology of aging. There is so much information on the subject out there and Margit Henderson does all the hard work of sifting through some really dense subject matter. The book provides a wonderfully succinct summary with action steps to formulate your own plan at the end each chapter. It can be read in parts or as a whole and so one can jump around in the book to access the information that is most relevant to the reader. A must read for those of us in our middle years who hope to have a happy and healthy journey into a ripe old age!
