"No evolutionary biologist will ever tell you that humans have evolved to mate for life. Lately some of them will tell you that humans have evolved to pair-bond for four-year increments (about as long as it takes to get a child up and running), which seems about right. This information is not particularly hard to come by. But a weird thing about the show [Millionaire Matchmaker], and about American culture in general, is that we are so eager to hear and believe scientific and pseudoscientific explanations of why people "fall in love," but then we cover our ears and hum so that we don't hear the end of the sentence, which is about why people fall out."
