Good reader, and many interesting stories about persons whose injuries allow a closer examination of those parts of the brain that control habits and other behaviors. And some of the other stories well researched (London Subway Fire, Rosa Parks boycott, etc,) and were interesting.
No. This is a collection of stories looking for a theme. In fact, it seems like he had to work hard to find a theme to fit his stories. The longer I read, the thinner the connection.
In the final section, the author sets up a comparison between two individuals (a sleep walker who killed his wife and a gambler who spent all her family's money) and set up a red herring suggesting that habits out of their control forced their actions and they should have been treated equally. The weakness in the argument was so apparent that it was just irritating when he finally came around to make the obvious case that the gambler had many opportunities for intervention and the sleepwalker who acted once. So while I learned some things about habits early in the book and then listened to some interesting stories in the middle, the longer the book went, the more it became obvious that anything in this author's world could be easily explained--and included in--a book about habits.
I really didn't learn much from this book, and so it came across and somebody nagging me to do things that we all pretty much know are important. So in comparison to books like Spark, this one was kind of a dud. I will say that the one thing I have tried to follow from the book is a little more sleep.
