Pea is a nerve stimulant synthesized by the human body itself, which can make people feel extremely excited. With this substance, both parties in love will "summon" and tirelessly provide confidence and courage in the process of love. However, don't think that pea secretion is a good thing. It will enhance people's self-confidence and make people crazy and irrational in love.

Peas can make lovers forget everything except love for a while and only pay attention to love, so there are sayings that "beauty is in the eye of the lover" and "a woman in love has zero intelligence". Generally speaking, the peak concentration of PEA can last for about 6 months to 4 years, with an average of less than 30 months.

Chemicals such as phenylethylamine in the human body cannot exist forever. After the passion of love and first marriage, chemicals such as phenylethylamine began to decrease gradually in about four years until they disappeared.

It stands to reason that this will cause the relationship between husband and wife to gradually fade. In fact, the feelings of most couples will be further deepened and consolidated. This is because couples who live together for a long time will produce endorphins similar to sedatives, which can make couples depend on each other and even be inseparable, deepening their love.
