人生最重大的任务：即人活在世上的时候要繁衍后代，并把他们抚养***。

"我们已经学会了如何挑选配偶的类型并且满足异性伙伴的要求。"
引起恋爱欲望最初的一个重要因素很可能是潜在伴侣身上发出那种适合的气味。
好闻与不好闻的气味对双方来说根本没有什么差别；
好闻与不餐闻都是挥发性的分子从一方身体随风飘移传送给对方，并且还载着性 方面的暗示。

But the lure of losing our faculties is one of the things that makes sex thrilling—and one of the very things that keeps the species going. As far as your genes are concerned, your principal job while you're alive is to conceive offspring, bring them to adulthood and then obligingly die so you don*t consume resources better spent on the young. Anything that encourages you to breed now and breed plenty gets that job done.
