Dr. Xue Lian continued: "When a patient suffers from inflammation of the respiratory tract, such as sputum in tracheitis or bronchitis, or in a cold, he will spit out white or milky sputum;

"When there is purulent inflammation in the patient's body, due to bacterial infection and pus incorporation, yellow or green thick phlegm will be spit out;

"When a patient suffers from pulmonary edema, he spits out pink foamy sputum, and if the sputum is bloodshot, it is most likely tuberculosis;

"When a patient has a lung tumor, they spit out jam-colored phlegm;

"When a patient has lobar pneumococcal pneumonia, they spit out rust-colored sputum;

"When the patient is affected by his occupation, as he or she usually deals with iron, charcoal or dust, he will vomit gray or black phlegm due to the influence of environmental pollution......"

After saying this, Dr. Xue Lian raised her eyebrows and asked, "You said, all kinds of patients spit out thick phlegm of different colors with various bacteria and viruses into the spittoon, what has become of this spittoon?" ”

What has become? Isn't that dirty spittoon a place and the source of a hundred poisons?

Thinking of the thick phlegm as dirty as snot, Niu Tiangou felt a wave of nausea and a stomach surge. Pen % fun % Pavilion www.biquge.info

Dr. Xue Lian's "spittoon" theory is really a big "deterrent" for Niu Tiangou, just like a strong preventive injection, so that he no longer dares to live casually.

There was no quarrel, no warning, no cold war, and no coercion, Dr. Xue Lian just calmly and calmly reasoned by the way, and completely received his Niu Tiangou's heart into himself, so that he consciously and voluntarily no longer dared to easily mess with flowers and grass, and he could only find himself "tired" when he had passion.

Such a woman, such a wife, such an invisible trick, high, really high.

After being stunned for a long time, Niu Tiangou couldn't help muttering, "That's the case...... No wonder the ladies always carry condoms with them. ”

"You think it's safe to use condoms? Condoms are called condoms, and they only prevent pregnancy and are ineffective against many viruses. ”

Dr. Xue Lian gave him a blank look, she couldn't let Niu Tiangou have the illusion that using a condom was "safe", and then took chances: "Using a condom can only say that the probability of being infected with STDs is lower, but it cannot completely eliminate the possibility of being infected."

"According to a foreign medical journal, the failure rate of condoms to prevent AIDS is 16.7%~31%, and it cannot completely prevent 9 sexually transmitted diseases such as hepatitis B, AIDS, gonorrhea, chlamydia, syphilis, chancroid, venereal lymphosarcoma, genital herpes and genital warts."

"Why?"

"Because the material used in condoms on the market is mainly natural latex, its natural fissure is between 5,000 and 70,000 nanometers, which is enough to prevent the head of human sperm with a diameter of 5,000 nanometers, but the diameter of HIV is only 120 nanometers, the diameter of human ** tumor virus is between 45~55 nanometers, and the diameter of the large spherical particles in hepatitis B virus is 42 nanometers, which is easy to penetrate the small fissures that are not easy to detect in condoms.

"The virus will easily infect the human body through these cracks and minor abrasions."

"That means there's no way to prevent the spread of STDs right now?" Niu Tiangou seemed to ask unwillingly.

"Yes, wow." Doctor Xue Lian smiled faintly, "Clean yourself, stay away from external sex, and ensure that all poisons are not invaded." ”

"That'...... What if you're not at home and I can't help it? Niu Tiangou deliberately teased her, and the thief said with a smile.

Doctor Xue Lian Danfeng raised his eyes, stared at him for a while, then smiled lightly, and teased: "As long as you are not afraid of abscesses, flowers on your face, and death, you will boldly go to Miss." ”

Niu Tiangou hehehe, he posted it with a smile on his face, and said greasy in her ear: "Don't look for it, don't look for it, never touch it, thinking of the spittoon you said, I'm disgusted and nauseous, I don't want to be the second Zhang Dalong ......"

Although Niu Tiangou's words have a bit of a "show" flavor, they at least reveal part of his true feelings.

He believed that Dr. Xue Lian's words were not without scientific reason. Although the beauty is seductive, the shadow of the "spittoon" has taken root in his heart, and it can't be erased, it is like an invisible killer that makes him fearful, so that he has to be afraid in the future.

Dr. Xue Lian's "spittoon" theory is like an invisible anti-epidemic needle, which greatly curbs his cranky thoughts, awakens his fascination, and makes him have a considerable degree of immunity to temptation from now on.

The "spittoon" theory, high, really high!

Seeing his obscene look, Dr. Xue Lian gave him a blank look, pretended to be angry and gently pushed him away, got up and went to the bathroom to take a shower.

Niu Tiangou sat for a while, suddenly remembered something, and went into the bedroom and turned on the computer.

Enter the word "STD" in the search bar, press search, and a string of web pages about STDs will appear, Niu Tiangou casually clicked on a few web pages with pictures, and all kinds of pictures about STDs appeared in front of his eyes.

Looking at those strange and dazzling pictures, Niu Tiangou felt shocked!

Grandma's, is this God's punishment for human disorder?

Niu Tiangou could only see a churning in his stomach, a burst of gagging, and a cramp all over his body!

It's even more disgusting than a spittoon!

Niu Tiangou shuddered!
