People laugh. A lot. We do it involuntarily, sometimes in embarrassment, through comedy and jokes, or simply to feel more in with the crowd. It is a language in itself, complicated with its own syntax and a social way of communicating. But a lot of times we don’t really know why we laugh.

Next time you laugh, consider why you’re actually doing it and what meaning it has.
