New studies suggest that play may be as essential to our health as sleep. Here’s why—and how you can incorporate it into your grown-up life.

Some of these influences on development may stretch back a long way in time. ...
Some are biological and date back to before humans even existed as a species. Others develop as part of our social and cultural practices. We may never have the complete answer to what makes us a violent species. But we should always ask ourselves these questions -- if nothing else, we ...
Most of these things are learned in the long developmental periods that primates have, during which they engage in countless play experiences with their peers. [#paragraph7]There is a danger, of course, that play may be misinterpreted or not recognized as play by others, [#highlight11]...
