When we are children, we often hear teachers or parents say, "Pay attention to hygiene, wash your hands before eating and after using the toilet." So I often see a colleague touching the keyboard and mouse for a long time, buttoning the face, squeezing the acne, and then going to the toilet to help JJ pee, and after peeing, wash and wash their hands and work with peace of mind.

One day, I couldn't help but ask my colleague Brother Dao, your hands are salty, will it be unhealthy to touch JJ directly! Brother Dao said, how can it be, I have always insisted on the good habit of washing hands before and after meals, I said Brother Dao, let's make a bet, I will tell you a way to cure your prostatitis, Brother Dao said with a questioning expression What method, I said to change the habit of washing hands before and after meals to wash hands before meals, before using the toilet, and after using the toilet! Okay, please eat Malatang!

Today, Brother Dao invited me to eat pork belly chicken, happy!

Juvenile pandas will eat the poop of adult tomcats. Ninety-nine percent of the panda's food is bamboo.

Roses are more durable when picked in the afternoon than in the morning. This is biologically speaking, because the roses in the afternoon experience the whole day's sunlight, the carbon dioxide concentration in the plant is very low, and the plant is neutral or weakly alkaline, in this case, the rose is less likely to rot, and the pigments such as anthocyanins are not easy to be destroyed.

When I was in elementary school, I was short-sighted when I watched TV. When I was in junior high school, I played less on the computer and watched less TV so that I would not be short-sighted. I didn't have time for that in high school. When I arrived at university, I was urged to watch TV every day, in order to make me play less mobile phones and not make my eyes more myopia.

Natural vitamins are no better than synthetic vitamins, and there is no difference between natural vitamins and synthetic vitamins, on the contrary, natural vitamins are more likely to introduce contamination and impure substances in the production and extraction process.

Many people think that eating chili peppers will cause acne, but in fact, excessive hormone secretion is not about chili peppers, but on sugar, which has an ingredient in sugar that is easy to cause hormone synthesis.

The truth does not become clearer the more you argue. Two groups of people with different levels of thinking will not reach an agreement, even after countless debates. Take my mom, for example.

She is a deeply superstitious person, and all kinds of earth and mountain gods will worship tirelessly, and there are a bunch of taboos that have no meaning, even if it is a waste of money. In this regard, I was not only worried about her safety, but also too disturbed by some taboos, and I couldn't convince her, and I would be scolded by her in the end. I'm tired anyway.

Pillows are not for pillows, but for necks. The cervical spine has a curvature, that is, there is a bend, which is called cervical curvature. If we put our head on the pillow, the head is comfortable, but the cervical spine loses its support and becomes suspended.

Over time, it may induce problems such as cervical spine deformation and cervical spine pain. Sometimes when you wake up, not only do you not feel refreshed, but you are dizzy and your neck is sore, which may have something to do with the lack of a pillow. So, pillows are for the neck!

In fact, cold hands and feet are not necessarily a bad thing. In fact, cold hands indicate good health. Healthy people with low blood pressure, both indoors and outdoors, usually have normal blood flow to the trunk, but the temperature of the limbs is low.

However, if your hands are cold and accompanied by hair loss or amnesia, you may have hypothyroidism. If it is accompanied by numbness or tingling, it indicates vitamin B12 deficiency; If it is accompanied by pain, burning, or significant pallor of the fingers and toes, a more severe peripheral vascular disease of the heart should be sought.

No treacherous business, obviously dejorative, but this word is obviously discriminatory, is there really no conscientious businessman? Not to mention, the ancients used this word to praise merchants! The prototype of this word is "no tip no business", which refers to the fact that some rice sellers will weigh the amount of rice that customers want to buy, and then give some rice as an add-on, similar to today's buy ten get one free.

These rice as additives will make the rice that customers buy a point, so there is a saying that "no tip is not business". As for today, it is said that there is no treachery and no business. It's all made up by later generations.

Everyone has to believe that there are still conscientious business drops.

If you need help, don't yell at a crowd, "Please help me." "Quickly find someone who is most likely to help you, and then hold him down.

Human limbs are underdeveloped, and their strength and speed are much worse than those of lions and tigers, but in addition to using tools, when hunting, human bodies are at least in one aspect of abusing these beasts, that is, the development of sweat glands. The well-developed sweat glands make humans have strong endurance and are good at long-distance running, and they can control their body temperature by constantly sweating, and it is not a matter of running dozens of kilometers in a row to chase prey. Although some of the prey that are being chased run fast, the sweat glands are not developed, and if they run for too long, they will die of heat.

Prey either runs or stops to dissipate heat, while humans can dissipate heat while running. Therefore, the hunting of the ancients sometimes chased the prey to death. The seemingly weak human body is much stronger than the beast in this regard. ‍‍

When you have a nosebleed, you should not look up, but keep your head down to let the blood out. If you tilt your head up, the blood will coagulate into a blood clot after it dries, and it will bleed again when you pick it. This is what I saw in a magazine when I was very young.

Every time a friend has a nosebleed, I tell him, but unfortunately he is too busy to stop the bleeding and listens to me. ‍‍

The ancients, in the pre-Qin period, they talked in the format of classical Chinese on weekdays, but since the Tang Dynasty, it has basically become vernacular, and classical Chinese is just a form of writing. These vernacular words are actually similar to our current ones, and vernacular books such as Water Margin can represent some of them, but whether they are vernacular books or not, since they have become books, the way these vernacular books speak is actually a little bit more than the real words at that time. Song, Yuan, Ming and Qing dynasties, especially in the Ming Dynasty, the government's notices and everything require the use of vernacular.

Eating only fats (meat, eggs, milk) will make you thinner, and eating only sugars (pasta, candy, cola) will make you thinner. What really makes people fat is sugar + fat because it gives people a sense of pleasure and unconsciously consumes too much. To put it simply, it's delicious.

The scary thing is that almost all of our food pairings are sugars + fats. ‍‍

Typically, our noses work in shifts. That is to say, both nostrils will not be used to breathe at the same time, and they will take turns breathing left and right, maybe today the left nostril will be the right nostril tomorrow.

Our human vision is amazing. Human glasses are convex lenses, so the images presented on our retina are actually the opposite of the real world, but they are transmitted to the brain through the optic nerve, and the brain adjusts our vision to make it "right". ‍‍
