Happiness levels are really high when we’re young. They then steadily dip through our 20s, 30s, and 40s, and bottom out in our early 50s–at which point, they make a sharp and sudden rise. Then, through our 60s, 70s, and 80s, they are way above where we were in our youth.  Why is this? Why do we get happier even as our bodies are falling apart? Here’s another question: Why, from the standpoint of evolution, do humans stick around way past the point of reproductive age? The answer to all of these questions, per our guest today, is: wisdom.  Dr. Dilip Jeste is a Distinguished Professor of Psychology at the University of California, San Diego, and the author of Wiser: The Scientific Roots of Wisdom, Compassion, and What Makes Us Good. In this conversation, we talk about how exactly he defines wisdom, what people of all ages can do to become wiser now, and the relationship between wisdom and loneliness. A quick content warning: this conversation includes references to sensitive topics, including suicide, substance abuse, and depression.
