Query: A very interesting book

I know of Dr. Norman Rosenthal as an outstanding psychiatric researcher, but it was a very pleasant surprise to find his new book, The Emotional Revolution, so fascinating and readable. The book is packed with wisdom, stories and hints that could be useful to anybody.I liked the way Rosenthal shows how emotions can help or hurt us depending on their degree and context. One story that comes to mind is about a woman who ignored her fear instinct to her regret, but there are so many interesting tales that it is worth reading for them alone. Rosenthal's description of a visit to the famous neurologist and legendary Holocaust survivor, Viktor Frankl, was particularly moving to me.Bottom line: I enthusiastically recommend this book to everybody.
