Harvard Study of Adult Development

How can a life be visualized? Can a happy life be captured in numbers and diagrams?

The Harvard Study of Adult Development is the longest prospective study of mental and physical well-being ever conducted. For 72 years, researchers at Harvard have been following 824 individuals—all selected as teenagers for different facets of mental and physical health more than half a century ago— through war, career, marriage and divorce, parenthood and grandparenthood, and old age.

In this book, I'm taking 10 representative case studies and visualizing their salient character traits, personal timeline, social supports, and physical health to draw conclusions about "the happy life."
