Attractive Women Make Men Temporarily Stupid
Ponca City, We love you writes "The Telegraph reports that men who spend even a few minutes in the company of an attractive woman perform less well in tests designed to measure brain function than those who chat to someone they do not find attractive. This leads to speculation that men use up so much of their brain function or 'cognitive resources' trying to impress beautiful women, they have little left for other tasks. Psychologists at Radboud University in The Netherlands carried out the study after one of them was so struck on impressing an attractive woman he had never met before, that he could not remember his address when she asked him where he lived. Researchers recruited 40 male heterosexual students and had each one perform a standard memory test. The volunteers then spent seven minutes chatting to male or female members of the research team before repeating the test. The results showed that men were slower and less accurate after trying to impress the women. The more they fancied them, the worse their score."

Now, you know that whole "chemistry" thing, where some people strike you as attractive and some just... don't? That's in part determined by the differences between your immune systems.
That works because if the genes that code for your major histocompatibility complex (MHC) are similar to the other person's, you'll tend to find them less attractive than otherwise, and vice-versa. Why mate with someone who's immune to the same stuff you are? Your offspring won't have any survival advantage. Instead, evolution has selected for creatures that mate with partners whose immune systems are incompatible. Either because both parents tend to be unlikely to be sick at the same time, ensuring the presence of at least one caregiver. Or because some the offspring of such pairings get a mix of genes that features the the best bits of both parents. (Offspring that get the worst of both parents tend not to survive, but that's a problem for individuals, not the species.)
Love is just a chemical reaction in your brain, anyway. It's not magical, or sacred, or even very special. It's your brain recognizing the opportunity to mate with someone who matches your particular template for an ideal partner (usually based on early experiences, parents, and other external factors), and shooting you up with natural drugs to make you feel like it's way more than it really is.
