Actress Cameron Diaz wants common people to be on the cover of the second book that she is penning. It will center on the mental, physical and emotional journey of ageing. After The Body Book: The Law of Hunger, the Science of Strength, and Other Ways to Love Your Amazing Body, her first book which landed her in the The New York Times’ bestseller list, Diaz is working on The Longevity Book, reports eonline.com. “It is centered on the mental, physical and emotional journey of ageing, and as we diligently put the finishing touches on the book, we’d like to ask for your help once more. This book is for you and about you, and that’s why we’d like to see you on the cover. Much like the cover of the Body Book, under the jacket, where we featured women of all different shapes, sizes, builds and ethnicities,” she wrote on her website.
