"When you make out with someone (or swap spit), your body takes that genetic material and decodes if that person’s immune system is complementary to yours and would produce strong offspring. Your body (and brain) assess biological compatibility with our partners (or potential partners)."
When I read the title, I thought you'd be describing the obvious thing ... that the idea of swapping spit is pretty undesireable for most people ... unless their aversion is overcome by drugs (in this case, hormonal ones). But, I've never really considered the answer you gave, concerning bio-genetic compatibility testing! Thanks!
