Genetic speed dating

I think couples genetic counseling should include a phylogenetic tree where the lineages can be spread as much as possible. Imagine that?! It turns out, we are driven by pheromones after all and it is genetically determined ..

"Preferences for mates that possess genes dissimilar to one's own at the major histocompatibility complex (MHC), a polymorphic group of loci associated with the immune system, have been found in mice, birds, fish, and humans. These preferences may help individuals choose genetically compatible mates and may adaptively function to prevent inbreeding or to increase heterozygosity and thereby immunocompetence of offspring. MHC-dissimilar mate preferences may influence the psychology of sexual attraction. We investigated whether MHC similarity among romantically involved couples (N= 48) predicted aspects of their sexual relationship. All women in our sample normally ovulated, and alleles at three MHC loci were typed for each person. As the proportion of MHC alleles couples shared increased, women's sexual responsivity to their partners decreased, their number of extrapair sexual partners increased, and their attraction to men other than their primary partners increased, particularly during the fertile phase of their cycles."

From the heart .. to T.
Gosh, it has been so long but he enticed me to write again,
Something about him makes me stop in my track ...
The way he's atonal and all around on that planet of his. The way he pauses after making a point, looking so satisfied .. just by the mere fact he is living and trying and listening and helping .. The way he knows and notices that i always use two points in my suspension points and the fact he is the only one able to figure this reference out .. the way he says okhte .. his vast ability for understanding and his love for the water and the sun .. his ability to love and to contain me even when i do not contain myself .. the way he is protective in the most gentle effort and he is distant at the same time .. i have never .. and i will never .. feel enchanted and puzzled by a man .. the way i feel ..
Exquisite is this raw feeling .. this little adventure that had a "time table" and took on a life .. a force .. strange is this gentle energy that calms mine down to the point of starting to use the word energy ..
Not writing poetry yet but certainly writing ...
