Why Men Want Sex and Women Need Love Read Online Free PDF Page A

instant hormone surge. It also helps explain why men are more likely than women to fall in love at first sight.
    In essence, men use their eyes primarily for evaluating the potential of a woman. When men are turned on, they become flushed with hormones and have erections. These hormones can overtake rational thinking, and therefore men can make decisions that may not be in their own best interests. It becomes a situation where his erections override his brain. This is hardly a shock to any woman who has had experience with men. These scans corroborate the research by David Buss showing that these behaviors are a universal, cross-cultural phenomenon.

How Women’s Brains Rate Attractiveness in Men
     
    Studies of women’s brain scans revealed something very different from the men’s scans. In women, several brain areas associated with memory recall became active when evaluating men for attractiveness. In evolutionary terms, this is an adaptive strategy to remember all the details of a man’s behavior.
    For hundreds of thousands of years, women have had the job of raising babies to a stage of independence. Motherhood is a complex job, and it is harder for human females than forany other mammal. Human mothers need support and protection when feeding and caring for their offspring. In prehistoric times, if a woman’s partner died, she’d need to expend an enormous amount of energy to find a replacement. Unlike a man’s immediate visual approach to evaluating the opposite sex, it’s not possible for a woman just to look at a man and know whether he’s honest and trustworthy, whether he can hit a moving zebra with a rock from fifty meters, or if he’ll share the meat with her. The same evaluative process is used by a woman today to be able to remember things such as what a man said yesterday, what he said three weeks or three months ago, how he reacts to children, whether he is kind and generous, how he treats his mother, his employment history, and his assets, and she’ll use all of this to evaluate his potential as a partner. When a woman studies images of one man, she recalls other men she knows who have similar features and then recalls their personality traits. Her brain then decodes the traits that correspond to the face of the man she’s looking at. It’s as though she is putting together a mental jigsaw of one man’s character by using a database of pieces of many other men. This doesn’t mean she gets it right; it means that she constructs a mental composite based on the men she knows. While women’s brains are recalling data about many men to assess a man’s potential as a partner, men just take long, hard, and many obvious looks at women. Now you know why women never forget and men are always being caught ogling women.

Why Lust Doesn’t Last
     
    Donatella Marazziti, a psychiatrist at the University of Pisa, Italy, investigated the hormonal changes connected to obsessive-compulsive disorder (OCD) with a focus on serotonin, the chemical that has a soothing effect on the brain. Too little serotonin has been linked to aggression, obsession, depression, and anxiety. Drugs in the Prozac family fight these conditions by boosting the chemical’s presence in the brain. Marazziti was intrigued by how both people with OCD and love-struck individuals can spend hours fixating on a certain object or that certain someone and how both groups often know their obsession is irrational but seem to have no control over it. She measured the serotonin levels of twenty OCD sufferers against twenty “madly-in-love” people. She then compared the results against another twenty people who were not affected by OCD and were not in love. While the “normal” subjects had the normal level of serotonin, both
