We think that we are all individuals who operate on a conscious level of free will...But we're not.
The human animal is driven by Primal Instincts. These instincts push us to eat, to sleep, to find a mate, and to reproduce.
If you think that you are above that level, chew on this:
When women are in the fertile/receptive period of their monthly cycle, their lips swell slightly and redden. This is a signal to men.
When Barbara Walters interviewed Monica Lewinsky on national television the number one question viewers asked was "what lip gloss was Monica wearing?"
Ha! And I thought I just wore make up to look prettier.
