I received the Medicare & Social Security audiobook free in exchange for an honest review. It was 3 hours packed with information about retirement health and financial benefits in the USA when you get to that magical age. I am a couple of years away from retirement but this set answered a lot of questions for me and my husband (who is a few years closer than I am!).
Look into this book set when you are wondering when to file, how to file and not receive your money right away, and how to file and then stop receiving money, and why you would want to do any of these things based on your situation.
