Well worth an examination

Wow, Cor, Phew - what is this girl doing?  Why - improving her chances in an exam, according to Polish researchers.

Girls who wear red underwear get the highest grades in examinations- so in Poland you can't buy red knickers for money or love - well - erm - possibly love then.

Now think about the poor guys.  How on earth are they going to pass with tests when all they're going to be thinking about is what colour lingerie have the girls got on.
