I'm a bit confused by your first statement, that "strong sexual
attraction is related to inverse odors associated with the immune system
and the gene markers of the person doing the smelling." I mean, it's my
understanding that olfactory cues are critical to sexual attraction in
mammalian systems as well as in the insect systems wherein pheromones
were originally identified (I think pheromones were first identified in
insects--- apologies, Dr. Ruth!)--- but what does this have to do with
the immune system? Are we saying that the olfactory system must use
something like VD(J) recombination to generate the diversity of
chemosensory receptors necessary to differentiate between the diversity
of odor cues? I've heard such things discussed from time to time. Or
are we ignoring the mechanistic details and just throwing these ideas out
there to see what kinds of ideas, what kinds of criticisms they invoked?

Now that I'm "self-employed," should I change my disclaimer to read that
*I* should not be held responsible for any of the opinions expressed here?
