Hormone decides love at first sight, dopamine decides eternity. What do you mean?

Because hormones are the reaction of male hormones and the expression of the degree of love for friends of the opposite sex, hormones determine whether they fall in love at first sight.

Dopamine determines the eternity of love, and also determines that love will never be separated. Dopamine is a neurotransmitter, a chemical used to help cells transmit pulses. This brain secretion is related to people's lust and feelings, and it conveys information of excitement and happiness.

Adrenaline is also a hormone and a catalyst for passion and courage. Adrenaline decides whether to take action after love at first sight.

Reasons for the existence of phenylethylamine

Scientist Fisher speculated that there are many reasons for the occurrence and development of human passion and emotion. Passion can make people distinguish which mating objects are among all sentient beings, and let "a couple continue to associate until sexual behavior happens naturally"; And feelings "can make couples endure each other's shortcomings for a long time and have children with him or her."

Studies have also proved that love and desire are obviously different for human beings: human sexual behavior is more stimulated by hormones such as testosterone (both men and women), but testosterone can't make people love.

Sociologists say that most of our marriage customs are to mediate the tension between love and desire. Pepper said, "Many people long for romantic passion, but most people need loyal and friendly love".
