Play deprivation is a major cause of the teen mental health crisis
This may be obvious or well-discussed but I had an epiphany some years back when my dad, regarding my kids, said (paraphrasing),"they're not playing. 'Play' is a misleading term. They're testing the world. They're learning how things work. How gravity works. How friction holds lego together. How actions cause reactions. How friends and strangers behave when you do things. How to use language with make believe. How to comfortably and safely explore new ideas out loud with their action figures. How to discover what feels good and what doesn't.  They're not playing. They're growing."My kids are young. But I'm confident this is generally true for teenagers, too. One quick example: I played WoW and looking back... I learned a ton about how to work in a team. How to be social. What social behaviours work and don't work. How to deal with people you don't like. How to delay gratification. How to plan.  And it was all in a low-stakes environment.
