Psychology says people who put their date of birth or year in their email address aren't trying to reveal too much: What this habit may actually mean?

Psychology says people who put their date of birth or year in their email address aren't always sharing personal information without thinking. In many cases, the habit develops for practical reasons, identity needs, or because preferred email names are unavailable. Psychology explains that such choices can reflect convenience, self-identification, memory support, and digital habits. Understanding this behavior can help people create better online identities while also protecting their personal information.
