Query: I found this information very useful

I was surprised at how much I have gained by the simple common sense solutions, to issues I am faceing as I grow older, provided by this book. I was most impressed with the fact that it spoke to me in very relatable terms. The author addresses current topics and problems that I have personally experienced. Such as, coming into Middleage without the friends I had been growing up with in my 30s. And living in a social system that is focused on appearences and youthful activities. I did benefit more from the direct information provided by the author, vs the individuals statements from the case study participants. He focused on the topics and solutions for dealing with them, where the individuals (many times) just pointed out their own specific problems.
