Sorry, guys, but it's been scientifically proven that a woman can now blame her anger and aggression on her genes. Scientific research found that some women are genetically programmed to be angry and aggressive by a serotonin receptor gene. The good news is that not every woman carries it.

What does this mean for you? Not only is anger and aggression in a woman the fault of her genetics, but it may be passed down to your daughters, too. Yikes.

Bad enough, but why are men so darn attracted to bitchy types?
