Social Relationships and Longevity: How They Connect

Written by Jordan Hamilton, Director of Behavioral Science

We know that social relationships impact healthspan. But I had no idea how much.

A new study just identified what separates "superagers", people in their 80s who score as well as adults 30 years younger on memory tests — from their peers.
The answer? Robust social connection.

Not just better diets or more exercise. Richer, more meaningful relationships. Larger social networks. More frequent, higher-quality interactions. And neuroimaging confirmed it: their brains looked structurally younger, with a thicker cortex in regions tied to memory and cognitive resilience.

The anterior mid-cingulate cortex, the brain's hub for motivation, effort, and cognitive persistence, is measurably larger in superagers. And one of its most powerful inputs is feeling seen, challenged, and genuinely engaged by the people around you.

Social connection isn't a soft science. It's brain medicine.
It's why we treat the Connect Pillar as foundational to healthspan at Optispan, a core biological driver of how well and how long we live. Most longevity conversations obsess over biomarkers and blood panels. I get it. But if we're not investing in the depth of our relationships, we may be leaving our most powerful neuroprotective tool on the table.
