This   (CLICKY)   is a very long article, so I'm quite sure that those who need to read it the most will not do so. Nevertheless, it gives an excellent overview of the nature of scientific research into gender orientation with a good look at the findings so far.

This is a challenge, which, as I say, those who really should read it will undoubtedly wimp out on because they won't want to read what it has to say.

There will be a test!
