"What makes a life fulfilling and meaningful? The simple but surprising answer is: relationships. The stronger our relationships, the more likely we are to live happy, satisfying, and overall healthier lives. In fact, the Harvard Study of Adult Development reveals that the strength of our connections with others can predict the health of both our bodies and our brains as we go through life."--Provided by publisher.
