As a septuagenarian, I like reading books on health, as to be healthy is the most important thing at this juncture of my life.  Recently I read this book: "Anti-Ageing Handbook" by Dr. Geraldine Mittons - New Holland Publishers (UK) Ltd. I particularly like this piece: What is youthful ageing?  Good health and youthful ageing have many dimensions.  This means having all your body parts in good working order; having a good memory, with precision in thought and action; having enough energy to enjoy physical activities; going to sleep and awakening easily; being able to laugh and be playful; being able to love and be loved; being able to enjoy the support of a wide circle of friends; being flexible and open to new adventures; being able to  appreciate the beauties of nature and the environment; having a purpose and meaning in life; having spiritual well-being etc, etc.

I feel inspired on reading this book.  It has lots of advice on keeping you healthy and to be healthy is my magnificent obsession.
