If one day I cry, what is the reason for that?

When tears suddenly welled up, I thought: Why do people cry? Primates, humans are the only ones who shed tears.

Charles Darwin, the founder of the theory of evolution, once speculated that tears were the relics of some kind of evolution... When crying, the microvessels around the eyes become congested, and at the same time, the small muscles contract to protect the eyes, causing the lacrimal glands to secrete tears...

For the human body, tears are a by-product of no effect, and the American anthropologist Montago has the exact opposite theory: human tears are the result of the survival of the fittest. Tears contain lysosomal bacteria, a self-defense substance that protects the nasopharyngeal mucosa from bacterial infection...

Then there were studies that divided tearing into reflex tears and emotional tears... The protein content of reflex tears is significantly lower than that of affective tears... This protein is a painkiller-like chemical...

Tearing is an act of excretion... It can eliminate the biochemical toxins caused and accumulated by the human body due to emotional stress... Restoring the mental and physiological balance of the weeping ...

Female ** tears are mostly emotional... The pain and sorrow of strangers cannot resonate suddenly ... That kind of feeling needs to be cultivated, just like watching movies and television, it needs to be sensational...

Just as in the old days of crying and mourning, we talked while crying... I think of some trivial things when we get along... No one goes home anymore ...

No one checks whether the doors and windows are closed every night before going to bed... No one cares about warmth and coldness anymore ... I also remembered some things that I didn't do well...

Once impatient emotions ... That's how I couldn't help but cry... It's a confession...

Crying can be many ways, happy will cry, sad will cry, moved will cry ......The things hidden in the heart are often what you don't want to mention and don't want to remember, but you can't forget it, since you can't forget it, why try to forget it, isn't it better to face everything happily?

It's just dead....And not a celebrity....It's the same as a pig died....I won't know you're dead at this time....Because I didn't even know there was you...

I come from among the clouds, and the white clouds are my resting place!

I don't have a peaceful life, and when the rain comes, I am dyed black with the white clouds, drifting with the wind and rain!

At last it dissipated, and I left, hurriedly, and walked so empty....Now you love him in your heart, and suddenly I feel that saying you love and hate you is just a superfluous companion talk!

I love your heart, how can you bear to smash it hard.

The comfort to you, those sincere pains, is it just a misunderstanding on my part!

The tears that flowed, the heart snuggled tightly, it was all in vain.

The heart you loved, how can I get it back, it turns out that everything is just a misunderstanding on my part.

I don't care, all the sorrow is up to me, don't say anything, your smile reveals your choices.

Our past, forget, forget!

I can't hear your sweet words anymore, I can't feel your messy mess anymore, and in the end I can't see you, I'm gone, I'm gone, I'm gone, I'm so empty....

Our love, it turned out that everything was just a misunderstanding on my part.

Love is pathetic.

You will meet all kinds of people in your life, stop gossiping and believe that you are right.

There is a lack of trust between you.
