I've been reading more non-fiction books lately and recently completed two that you might want to check out (literally as from the library LOL).
Drop Dead Healthy by A.J. Jacobs is another one of those months long self-improvement projects documented in book form. I like his writing style though and he is careful to clarify the scientific or not validity of what he discusses. An easy and informative read.
A Bittersweet Season: Caring for Our Aging parents and Ourselves is by Jane Gross who also writes the NYTimes The New Old Age column which I highly recommend. This book is a combination of her personal story of her Mother's final years and all of the decisions (good, bad and ugly) that she, her Mom and her brother made about living situations, finances and care. She also expands on topics with additional factual information. Her discussions of Medicaid spend down and application, what assisted living is and isn't, the challenges of finding a new primary care doctor who takes new Medicare patients who have moved away from their existing doctor, etc. are worth the read if you are in the midst of or potentially facing helping to care for an elderly person.
