I once again think of what Xizhen said about love-dopamine. Dopamine is a key neurotransmitter in hypothalamus and pituitary gland. The concentration of dopamine in the central nervous system is influenced by mental factors, which directly affects people's mood (recorded in the encyclopedia). Scientists use dopamine to explain love. Dopamine participates in the process of love and stimulates emotions. Love a person, because the body secretes abundant dopamine, no longer love a person, because this strange thing is exhausted. According to the data, when we fall in love with someone, dopamine only exists for 18 months. In Korean dramas, the time limit is two years, and at most it is four years. The peak of instant passion and fanaticism brought by dopamine is always short-lived. Because the human body can't bear the constant stimulation of ingredients such as cocaine, it will inevitably let those chemical ingredients metabolize naturally under its own control. We watched our love disappear. When love withers, taking dopamine can make love last a lifetime? Masanji has been looking forward to having him all his life without getting tired and dying. Perhaps, after years of turning on the TV or strolling down the street, "Do you need a cup of dopamine?" Don't let your love wither. " "Take a shot of dopamine to defend your love." People are complex, thoughtful, emotional, responsible, forbearing and tolerant (in fact, many animals in nature always guard one side, such as wolves and love birds). Most people, without dopamine, can tolerate a dull time because of other factors. Love is dopamine, but it's not just dopamine. More often, it is an attitude of knowing how to choose, knowing how to advance and retreat, and a responsibility to life and others. Dizzy, go to sleep! There will be classes for students tomorrow, and the task is arduous! If you don't have black eyes, the skin near you will be terrible.
