There was a programme on BBC1 a while back (can`t remember when) which was also interactive so you could answer questions to tell you if you are a lark or owl.
Maybe you could find it from the BBC or something and do the question and answer stuff. (sorry- vague!!!)
it was all scientifically conducted and presented by that dr guy with the dark hair and moustache who presents a lot of science programmes
lol this is a very vague post
