Sorry, I’m still dropping science on your bastard asses. Genes, germs, and environment. Who you are is very likely beyond your control.

Fucking fascinating.

Science has also provided a little comfort as to why your amorous advances are sometimes spurned. A famous study had women sniffing the underarms of T-shirts worn by men and then ranking the odor. The more similar the men’s and women’s immune system genes were, the worse the T-shirt stank to the women. There is a sound evolutionary explanation for this: If parental immune genes are too similar, the offspring will not be as well equipped to fight pathogens. In this case, genes used odor receptors as a proxy to size up whether a potential mate’s DNA is a good match. Studies like this affirm that chemistry between people really is a thing. Perhaps we should not take another’s romantic disinterest personally but view it more like organ rejection.
