Harvard Thinking

Just under half of households in the U.S. own dogs and say they view their dogs as members of their family. The love goes both ways. Dogs depend on us for their survival, just as humans benefit from their presence. Research shows that having a furry companion is good for us physically, emotionally, some might even say spiritually. In this episode, host Samantha Laine Perfas talks with bestselling author Alice Hoffman, lifestyle medicine expert Beth Frates, and evolutionary biologist Erin Hecht about why we love dogs so much – and why they love us back.

It’s common for our brains and bodies to atrophy with age. But some adults, those known as super-agers, have shown that we may be able to keep the sharpness of someone decades younger, even matching the cognitive abilities of a person in their 20s. In this episode, host Samantha Laine Perfas talks with biologist Will Mair, neurologist Alexandra Touroutoglou, and geriatric doctor Suzanne Salamon about what we’ve learned about super-agers and the secrets that may help us all extend and enrich our later years.

Owning a home feels increasingly unattainable for many middle-class Americans. Last year, home prices surged to nearly five times the median income. Yet the pace of building new housing, which could create more affordability, remains slow. In this episode, host Samantha Laine Perfas talks with urban economist Ed Glaeser, former CEA chair Jason Furman, and innovative housing expert Amy Tomasso about how those hoping to buy can make sense of the current housing crisis.

Different forms of adversity – like abuse, violence, and neglect – not only damage our physical and mental health but also change our cells. Scientific advances in the biology of adversity are showing us that in some cases, the harms of negative experiences run dangerously deep in our bodies and minds. In this episode, host Samantha Laine Perfas talks with children’s psychologist Kate McLaughlin, psychiatric epidemiologist Karestan Koenen, and cellular biologist Jason Buenrostro about what the future holds for protecting people from their worst experiences.

Marriage has evolved a lot through the years – and so have the problems and rewards that come with it. Research suggests it benefits our physical and mental health, but it might not seem like it when conflict arises and couples struggle to co-manage a household. With greater social acceptance of a variety of lifestyle choices, many people – especially young women – are thinking twice before tying the knot. In this episode, host Samantha Laine Perfas talks with business professor Debora Spar, psychiatrist and family counselor Richard Schwartz, and bestselling author Eve Rodsky about the role of marriage in modern society.
