In this groundbreaking relationship book, positive emotions expert Barbara L. Fredrickson gives us an entirely new way of understanding love and appreciating its benefits. "A radically new conception of love."-The Atlantic Even more than happiness and optimism, love holds the key to improving our mental and physical health as well as lengthening our lives. Using research from her own lab, Barbara L. Fredrickson redefines love not as a stable behemoth, but as micro-moments of connection between people-even strangers. She demonstrates that our capacity for experiencing love can be measured and strengthened in ways that improve our health and longevity. Finally, she introduces us to informal and formal practices to unlock love in our lives, generate compassion, and even self-soothe. Rare in its scope and ambitious in its message, Love 2.0 will reinvent how you look at and experience our most powerful emotion. "I wish I had known years ago about...Barbara Fredrickson...In particular her theory that accumulating 'micro-moments of positivity,' like my daily interaction with children, can, over time, result in greater overall well-being."-Jane Brody, The New York Times
