If there is a new vision of what “The New Retirement” should be, it is the “all of the above” retiree: stay healthy, stay involved in something you are passionate about, and be a dedicated caregiver to your future grandchildren. In episode 1, we meet Esmaeil Porsa, the CEO of Harris Health, to hear about his arduous and shockingly improbable road to the top of Harris Health, and what it means for the retirement that may not come as soon as his family hopes.

In episode 6, we explore an insidious epidemic, equivalent to the health effects of smoking 15 cigarettes a day. It can cause inflammation, heart disease, stroke, and type 2 diabetes. And it can cut our lives short by as much as 30 percent. It’s not Covid - or a virus - or a bad diet. It’s loneliness. More than 60 percent of Americans report feeling lonely and disconnected. And that number keeps going up. Today we’ll explore the health effects of loneliness. And our host Ken Stern comes up with an ingenious way to overcome his own feelings of isolation - as he sets out to make six new friends in his neighborhood.

Obesity rates have exploded in the US over the past half-century, with negative consequences for healthy longevity. We travel to rural Arkansas, where we visit countless dollar stores and explore the impact of ultra-processed foods on the obesity epidemic. We also examine potential solutions – from anti-obesity medication to Food Is Medicine interventions – as we begin to tackle obesity as a disease and not a personal choice.

In Episode 4, we explore how the built environment—and trees—impact communities. Renowned landscape architect Frederick Law Olmstead designed Buffalo, New York, around its parks, and it was once considered the best-designed city in America. But in the mid-20th century, one of his parkways was torn out and replaced with a highway that connected downtown with the new suburbs, in the name of urban renewal. We explore the impact of the highway on the surrounding community and traffic safety for automobiles and pedestrians alike. The city plans to put a cap on the highway to restore the urban parkway—and Frederick Law Olmstead's vision. But is it too late?

In Episode 3 of Century Lives Season 4: A Lifetime of Inequality, we go to Phoenix, Arizona, to understand how it is that the built environment can have great consequences for lifelong health and longevity. We focus our story on trees, which are abundant in wealthy North Phoenix, and almost completely absent in South Phoenix—instead replaced by concrete, warehouses, railroads, highways, and the like. In Episode 3, we discuss how climate change is only exacerbating the situation, and how the consequences affect predominantly poverty-level Black and Latino people.

As it turns out, a person's lifelong health and longevity take root even before they are born. Preterm birth and low birth weight are connected with a range of medical issues that span the life course—including all-cause mortality. But when it comes to maternal and infant health, complications for Black mothers and babies far surpass those of other demographics. In Episode 2, we head to Los Angeles County to find out why—and to learn how the African American Infant and Maternal Mortality Initiative is working fiercely to improve health outcomes for Black mothers and babies.

In Episode 1 of Century Lives Season 4: A Lifetime of Inequality, we visit Albuquerque, New Mexico, to explore the impact of early childhood education on lifelong health. The story looks at the impact of high quality early childhood education on health, and then follows the 12-year effort to pass Constitutional Amendment 1—an amendment to fully fund childhood education for all children in the state.

In our last two episodes of the season, we explore the challenges of concentrated urban poverty—and the depressive effects it has on health and life expectancy. And we examine two different approaches that might remedy it.

In episode 6: a story about going. We reexamine Moving to Opportunity: a grand 1990s public housing experiment intended to improve the incomes of public housing residents. That didn’t work, and the program was initially seen as a failure. But alongside the negative results, a positive and unexpected finding emerged, with a lesson about the surprising impact of neighborhood on health and longevity.

In our last two episodes of the season, we explore the challenges of concentrated urban poverty, and the depressive effects it has on health and life expectancy. And we examine two different approaches that might remedy it.

In episode 5, we tell a story about staying. We visit Woodlawn, a neighborhood in Birmingham, Alabama, that is literally on the wrong side of the tracks. We learn how health improves when a community that long suffered from disinvestment comes together to rebuild from within.

Do the ladies of the Quilt Guild, the short order cooks at the City Pool Hall, and “Pumpkin Joe” hold the secrets to longer life? In episode 4 of Century Lives: Place Matters, we travel to Eastern Kentucky: a region marked by drug use, job loss, and life expectancy decline. But these folks live in Wayne County, a bright spot where life expectancy exceeds that of neighboring counties by four years. In this episode, we investigate the role of weak ties and social cohesion in community health.
