In this conversation between Dr. Ben Rein, Neil deGrasse Tyson, Chuck Nice, and Gary O’Reilly, they explore the neuroscience of extroversion, introversion, and social connection — and how these traits directly affect happiness, brain health, and longevity. Dr. Rein explains that social interaction strengthens the brain like a workout, lowering inflammation and slowing aging, especially among extroverts. However, he emphasizes that introverts also benefit from connection — just in smaller, more meaningful doses that match their “social battery.” The discussion also touches on autism, social performance, and Dr. Rein’s concept of “social journaling,” a self-reflective practice to understand which kinds of social experiences make you feel best.
