I guess it's time for something other than cute pictures and videos...
I stumbled upon this in one of the recommended readings for a biopsych course: "Love joins hate, aggression, fear, expansiveness, withdrawal, and so on, in blends designed not to promote the happiness of the individual, but to favor the maximum transmission of the controlling genes" (E. O. Wilson, 1975). If you're feeling sentimental, you may take this as a romantic quote. But what it's really trying to say is that the brain isn't designed to benefit a person's happiness or even health; it was designed to produce the maximum amount of viable offspring (Darwinian fitness). So next time you feel like you're falling and the only thing capable of catching you is the person you're all starry-eyed for, just know it's you're brain's way of saying, "make as many babies as you are capable of raising to puberty, so that they too can trip over the stones of natural selection and unabashedly fall into someone else's arms."
