How ironic would it be that something which everyone got told off for doing in school was actually making us smarter all along? Scientists have put forward the theory that daydreaming can improve memory, future planning, creativity and more. This is brilliant news if youre one of those people who constantly find their mind wandering while at work - although maybe not so much if you're an air traffic controller - as it shows youre taking this brief moment of down-time to increase your smarts. What could be the next evolution in using daydreaming as a mind-improving tool? How about courses and degrees dedicated to the art? Just sit in a classroom and stare out the window.
