I just started it, and I'm loving it so far. I truly appreciate all the research she did to put this together. I read books kind of differently than a lot of people. I also skip to the back and see what's in the appendix, and in other books, I'll check out the index--this one, alas, has no index--and you can tell a lot about the book before reading it. This just looks like a very well-crafted book.
(But I do wish there had been an index.)
The whole concept of the happiness set-point makes so much sense to me. Mine is kind of high, Dear Hubby's is rather low, and this book helps explain how all of this happens.
I am also reading "The Genie in Your Genes", and find the two support each other nicely.
Thanks to LSC for setting up this forum--as I read more, I know I'll want to read what others say.
