We've been told for decades to slather on sunscreen and stay in the shade. But what if the real health risk is avoiding the sun?

Margie Lachman is a psychology professor at Brandeis University where she conducts research on adult development and aging. She is an investigator on the Midlife in the United States (MIDUS) study, in which they have followed thousands of adults for over 30 years to understand the variety of pathways to health and well-being in midlife and beyond.

In the new book, Primetime: A New Vision for Midlife⁠, she agues that midlife is not a period of inevitable decline but a crucial opportunity to shape healthier, more fulfilling aging through positive attitudes, strong relationships, and investments in physical and mental well-being.

In the second half of the show, entrepreneur Jane Marie Chen shares her own experience of midlife transformation. In the memoir Like a Wave We Break, she tells the story of achievement, burnout, trauma, and the hard-won discovery that we are more than what we produce.

What happens when screens stop being something we watch…and become a place we live? Today, The Atlantic writer Megan Garber unpacks the strange new social reality she explores in Screen People: How We Entertained Ourselves into a State of Emergency—where everyone’s performing, politics feels like plot, and “main character energy” starts to warp how we treat real human beings.
