The notion of men being less complex is not true in my humble opinion. That particular statement would question the roles of men in society. Think about it, you don't see as many poets, artists, scientists, musicians who are women in comparison to men. I am not biased, just observant. I know that some may probably argue about "men taking over women", but even that posesses a counter argument to itself.
It is true that women hide their feelings more so than men do. A woman is more prone at nuances, whilst the man just blurts out what is on his mind. I have read some articles dealing with this, but lets not get into a different topic here.
Concerning video games, I have made some keen observations that may ameliorate or somewhat expatiate this topic or discussion herein. My sister is a fan of video games. The paradox lies in that she likes violent games, e.g, World of Warcraft. From observing the game, the character kills others, fights, etc. I suppose that it is a matter of preference, but anyhow, an observance is an observance.
Returning again to the "complex" theme, my conjecture would hold that women are not more "complicated", if that's the word you want to use, than men are. In my college class, women are less striving to involve in phylosophical conversations, debates, and their views are generally that of trite, with no new information or argument involved. Men however are more apposite for such discussions that compare different thoughts and visions, and are more prone to get involved in conversations. I do not say this against females or males for that matter, I just relinquish my observations.
Breasts are reproductive organs in that they enable the infant to be fed via natural means. Therefore, they should be classifed as reproductive organs.
