I went on a field trip kinda thing on Friday, to a 'revision lodge'... where I learnt how to successfully revise, with a bunch of people from school. We stayed over and it was shit etc. etc.
But today we had this psychologist guy telling us about things. He said quite a lot of interesting stuff, but he also said that the more 'hard' or 'heavy' your music you listen to is, the bigger affected by it you are.
What I mean is, he said your IQ apparently drops when you've been listening to some metal music for a while, and your IQ increases when you listen to Mozart etc.
He said he'd done an experiment with some mice where he played them classical music, and gave them an exam, which they did successfully. He played them Black Sabbath and after a while, they started eating eachother and going mental.
