One thing that was not addressed in your book was health care. This is another reason why I hesitate starting my retirement even earlier. Perhaps you could write another chapter on what you do about healthcare.
For example, I had a hernia operation earlier this year, also I have had my appendix removed. I am in very good physical shape as I am a runner. However, sometimes these things happen. Fortunately, I have excellent health care insurance so I was covered from a major expense. How do you handle these things while Vanaboding?
