ELI5: Explain Like I'm 5

Social Age

Social age is an idea about how old people act, not how old they actually are. For example, if someone looks like they are nine years old, but they act like a grown-up, people might say their social age is much older than their actual age. It also means that people act differently at different points in their lives. For example, a teenager might be more outgoing and adventurous than an adult.
