Psychologists explain: Why people read their own old messages even years later but rarely admit doing so

People often reread their own old messages years later, even when they have no real reason to. Psychology suggests the habit can be linked to nostalgia, memory, curiosity, closure and the need to understand how much we have changed. Old chats can also act as a record of past experiences, allowing people to compare what they remember with what they actually wrote at the time.
