Don’t worry; there won’t be an exam. However, attraction is all about chemistry, and specifically, a group of chemicals called “monoamines.” These chemicals send messages between your brain and your body, and they’re the reason love can literally make your skin tingle or cause you to forget your name when you’re around the woman of your dreams.  Dopamine (where we get the word “dope”) is a “feel-good” neurotransmitter responsible for rewards and motivation, among other things. When you’re around a person you’re attracted to, dopamine is released into your brain, making you enjoy the time you spend together and want more of it.  Norepinephrine, sometimes known as noradrenaline (but not the same as adrenalin) is responsible for sending messages to your central nervous system. It helps decide what is most important to focus on at any given moment. When you lose track of time and end up spending 5 hours on a date with someone you’re into, norepinephrine has decided that the woman you love is more important than any of the other information around you.  Serotonin regulates a host of functions, including mood, sleep, body temperature, and sexual desire. When your skin starts to tingle around that special someone, it’s because serotonin has dropped your body temperature, making your skin slightly more conductive of electricity. Pretty magical stuff. Humans may also emit pheromones like other animals do, although scientists aren’t exactly sure if they work the same way. You can’t consciously smell pheromones, but your body picks up on others’, deciding what it thinks is attractive and what isn’t. Because so much is down to how chemicals interact in each person’s body, don’t take it personally if the woman you’re interested in doesn’t return your interest. It probably has nothing to do with you as a person. Studies show that your brain decides what’s attractive in as little as one second, and it’s not really within your control. Research has even shown that taking hormonal contraceptives can change a woman’s “type” at...

How would you rephrase that briefly using Vietnamese?
Tìm hiểu một chút về hóa học. Hiểu rằng không phải tất cả là do bạn. Học ngôn ngữ của tình yêu. Để ý dáng dấp của cô ấy. Giao tiếp bằng ánh mắt. Nở một nụ cười quyến rũ với cô ấy. Tìm hiểu đôi chút về sinh học. Đến gần hơn một chút. Mạnh dạn đi bước khởi đầu.
