• What constitutes a happy and fulfilled life?
• What is ultimately a good life?

These questions are attempted to be answered by a unique research conducted for the past eighty and more years at Harvard University. As part of the Adult Development Study, the researchers of the program have been following and continue to follow the evolution of hundreds of men and women throughout their lives. It is worth noting that the people participating in the study, which began in 1938, come from different economic and social backgrounds - privileged and non-privileged. The valuable conclusions that arise from the research are presented in this special book, which combines scientific data with hundreds of personal life journeys in an enjoyable narrative.

The most important of these will surprise you with its simplicity:

The key to a happy, fulfilling, and overall healthier life is our relationships with other people. The power of our relationships is a decisive factor for the health of both our bodies and our brains. Relationships in all their forms - friendly, romantic, familial, collegial, neighborly, or within the context of a common activity - contribute to living a good life. Thus, it is never too late to strengthen the relationships you already have and it is never too late to create new bonds.
