Stress Management and Stress Relieving Techniques

Utilizing the Internet, please research and find four books that you would recommend on stress management or stress relieving techniques.  You may use Amazon or some other popular book website.  Please provide the title of the book, author, cost, and a paragraph describing the contents of the book and why you think it would be important.
The second part of your research is to research three stress-relieving techniques that you currently are not using.  Describe them as much as you can.
