Hey, I found this well good link http://www.bbc.co.uk/science/humanbody/ You can do quizzes/tests like.. 'personality type' where you answer questions and it tells you your personality type, also 'spot the fake smile' it shows a clip of a person smiling and you gotta say if its fake or genuine. other quizzes are psychological tests and loads more. I think they are really interesting.
If anyone does any, post what you get and what you think. Thanks
