Whether in real life or in the movie, there are often such scenes: he and she meet on a specific occasion, no step earlier nor one step later, the two people who met in Pingshui just looked at each other, and then gave each other a polite smile, and from then on, only each other was left, which may be what everyone calls love at first sight.

But while enjoying delicious dog food, I wonder if you've ever wondered what would make you fall in love with a stranger who knows nothing at first sight?
Let's take a look at the scientific explanation!
In short, there are three main areas in the human brain that are related to love, namely the ventral cover area, the accumbens nucleus and the caudate nucleus.
When you meet the charming TA, the ventral cover area begins to secrete a large number of compounds such as dopamine and phenylethylamine, of which phenylethylamine is the most prominent, which can make people feel a feeling of extreme excitement. When this message is conveyed to the brain, there will be a state of "love at first sight": a rapid heartbeat, blushing, and even overwhelmed.
Finally, I wish you, who are still single, that you will meet love on the next corner!
