Men vs Women

This is a question men often ask:

"I really don't understand why a small rock would cause so much delight in women."

And men often continue by saying:

A small rock can set me back a few sets of good Hi Fi system. The way I see it, a few thousand dollars can buy me quite a few bits of technology like an Xbox, a psp, a 500GB hard disk and a great big LCD screen.

I read from somewhere which states that there is a medical reason that might explain this issue. The ability to see the colours Red and Green comes from the X Chromosome. Women have two X chromosomes while men have only one. When the genes on the X chromosome is non functional and since men only have a single X chromosome, they are unable to perceive the colours Red and Green.

Women are protected because if one X chromosome is faulty, they have another one which most probably will be normal. Research has shown that because women have two X chromosome, some women can actually see a wider spectrum of colours! So, for some women, instead of seeing just seven colours of a rainbow, they can actually perceive ten colours. That might explain why women value a diamond much more than men!
