Neto may never prove his theory in a clinical study—social connection is notoriously difficult to measure in a Petri dish—but his 113 years of life offer a compelling data set of one. He spent his days in the company of family and friends, prioritizing the “right hearts” over the right habits. He understood instinctively what science is only beginning to grasp: that the human nervous system is wired for connection, and when we are surrounded by those who truly see us, our bodies respond by staying.
The implications of his story are far-reaching. If we took Neto’s advice seriously, our pursuit of a long life would look very different. We might spend less time on treadmills and more time on front porches. We might worry less about the chemicals in our food and more about the bitterness in our spirits. We would acknowledge that a life stretched thin by isolation is not a life at all, regardless of how many years it lasts.
