The Lifelong Power of Close Relationships

From a Wall Street Journal essay by Robert Waldinger and Marc Schulz headlined “The Lifelong Power of Close Relationships”:

When it comes to understanding what happens to people as they go through life, pictures of entire lives—of the choices people make and the paths they follow, and how it all works out for them—are almost impossible to get. Most of what we know about human life we know from asking people to remember the past, and memories are full of holes. The more time that passes, the more details we forget, and research shows that the act of recalling an event can actually change our memory of it.
