This is a fantastic way to spend twenty minutes, it's a TED talk by a video game designer, and it's really a great talk (almost every TED talk ever is amazing, btw, if you've never seen one, you are in for 1000 treats.) Happy gaming, my dears! Ava https://www.ted.com/talks/jane_mcgonigal_the_game_that_can_give_you_10_extra_years_of_life
