Susan Pinker explores why residents of a Sardinian mountain village live exceptionally long lives, with equal lifespans for men and women.

These interactions reduce stress and enhance well-being more effectively than online communication or medical treatments. Regular social activities play a crucial role in extending lifespan and improving health outcomes.
