The Longevity Book

The Science of Aging, the Biology of Strength, and the Privilege of Time

Cameron Diaz and Sandra Bark


As soon as she turned thirty-nine, the questions began. In seemingly every conversation, journalists asked Cameron Diaz the same thing: Was she afraid of turning forty? “As these questions about my age became a consistent part of every interview,” she says, “I realized just how frightened we all are of getting older.” 

But instead of fearing the aging process, Cameron set out to learn more about it. And in this enlightening follow-up to the #1 New York Times bestseller The Body Book, she shares what she's learned.

The Longevity Book provides a comprehensive overview of the female body over time, from those first gray hairs that crop up in our thirties through the menopause transition that can begin in our forties or fifties to the increased health risks—for breast cancer, Alzheimer’s, heart disease, and more—we face in our sixties and beyond. Cameron shares cutting-edge research on aging, synthesizing insights from top medical experts with her own thoughts, opinions, and experiences. Informative, intimate, and hopeful, The Longevity Book offers an all-encompassing, holistic look at how the female body ages—and what we can all do to age better.
