What if your brain’s health in retirement depended as much on who you see as on what you eat or how you move? Neuroscientist Dr. Ben Rein, author of the new book Why Brains Need Friends: The Neuroscience of Social Connection, joins us to reveal how social connection shapes your brain. He explains why isolation is as toxic as chronic stress, how friendship fuels brain resilience, and why your dog might be one of your best wellness allies. In this e, ye-opening conversation, you’ll learn how staying socially engaged literally protects your brain from decline, the science behind “nature’s medicine” — oxytocin — and practical ways to rewire your social habits for longevity, joy, and emotional well-being. If you’ve ever wondered why friendships matter more than ever in retirement, this episode will change the way you think about your brain — and your calendar.

You’ll learn:

Why social interaction is a fundamental pillar of brain health, as critical as sleep and nutrition – and what happens when we don’t get enough of it
The invisible pattern of retirement isolation: how time spent alone steadily increases while connections with coworkers, friends, and family decline simultaneously
Why text-based communication doesn’t satisfy your brain’s need for connection (and what to do instead to restore the social cues your brain craves)
The surprising neuroscience behind why dogs are so good for us—and how they activate the same brain reward systems as human connection
Two scientifically-proven exercises you can start today to train your empathy and strengthen the brain regions associated with compassion and social connection

Ben Rein joins us from Buffalo, New York.

Wise Quotes

On Why Social Interaction is Essential

“As a social neuroscientist, so I have spent a decade studying the biology of our interactions and not just in my own studies, but in reading a ton of literature, there is so much science out there on this. Basically, interacting is really, I consider it a fundamental pillar of wellbeing. And that goes for throughout the entire lifespan. But I think there are especially sensitive periods where we really need interaction. And that is early life. And that is also late life. In early life, it really shapes the development of our brains. And in late life, it sustains the health of our brains.”

On the Hidden Crisis of Retirement Isolation

“The data show that as we get older, the number of hours we spend alone continues to rise. And similarly, imagine if the amount of fast food you ate went up steadily as you got older, or the amount of hours you slept went down steadily as you got older. We would be pointing at this and saying, oh gosh, this is really not bad. 75 year old people are not sleeping. They are eating fast food. This is super bad for their health, but we are not really looking at the social component of it. And that is why I really point to it and say this is something that actually I think has to be a need-to-have because it is really significant for the brain and body.”

On the Nightmare That Changed His Life

“That was the first time where I realized I am interested in the organ behind the behavior. I mean, what incredible computational power to be able to do that, that same computational power is behind all those behaviors that I am interested in from a psychology viewpoint. I cannot ignore this anymore. I need to change my major. And I did. And what is funny is the reason I shared the story of The Nightmare is because I actually think it reflects my brain playing out an undesirable future where I do not listen to that inner voice. And I end up in a career that controls me and does not let me do what I want. And I feel distorted. My identity is distorted. And I think that was sort of my subconscious trying to tell me, wake up. It is the brain. Study neuroscience.”
