What are some false common senses in our lives?

<> there are many times when we think that something is right, but in fact, there are many "I think" things that are wrong, for example, you think that walking is more tiring than standing, which sounds very logical, after all, one is in the middle of the action, and the other is doing nothing, but why is it so tiring when standing? Standing is no more comfortable than sitting, because while standing, the legs are constantly bearing the weight of the body, and conversely, when walking, each step allows the other foot to relax. Some people say that eggs should be refrigerated, otherwise there will be Salmonella, if so, the eggs should also be refrigerated**, this is actually because the number of Salmonella in the refrigerator is very small, however, in the alternating hot and cold environment than in warm conditions easier to help the growth of Salmonella!

Some parents will tell their children that overly acidic food can cause stomach perforation, which is a very common horror fairy tale for parents who want to stop their children from eating too many soda and other messy sweets but are helpless, we have to think that our stomachs already contain stomach acid to digest food, so our stomachs are not harmed by acidic substances. Also, there are many friends around us who love to clean, they brush their teeth after eating, but generally speaking, brushing teeth immediately after eating is not a very recommended practice, because the acid in food will erode the enamel, at this time, brushing teeth immediately will only strengthen the destructive effect of acid, therefore, the more recommended way is to rinse your mouth, first remove most of the acidity in your mouth, and then about half an hour later, and then brush off the food residue attached to your teeth!

Personally, I think there are a lot of "home remedies" and "local methods" circulating among the people, and some of them you will think are very right. In fact, many "local methods" are wrong, so let's take a look at what they are.

1. Combing your hair 100 times a day is good for your health.

Combing your hair 100 times a day is good for your health, and I believe many people have heard of this method. In fact, this method is not suitable for all people, people with oily hair, the hair will be combed less and less; People with dry hair are more suitable for combing their hair more, but also be careful not to use ordinary plastic combs, be sure to use combs made of natural bristles, so that it will not hurt the scalp.

2. Walking is more physically demanding than standing.

I believe that many people will think so, in fact, this view is wrong, because when a person stands, his legs bear all the weight of his body, and his feet cannot relax at this time. And when we walk, we only need one leg to bear the weight of the body, and the other leg is relaxed.

3. People with sweet blood are susceptible to mosquito bites.

Many people think that people who love to attract mosquitoes are because of the sweetness of blood, but in fact, this view is wrong, because mosquitoes can't smell blood at all. The truth is that mosquitoes are particularly sensitive to heat, so they love to bite people with hot bodies.

4. Smart people have big heads.

This statement is wrong, because the size of the brain is not the key to determining IQ, the level of IQ is determined by neural networks, so whether you are smart or not has nothing to do with the size of your brain.

5. Sweat is stinky.

I believe that many people will think that sweat has a smell, but in fact, sweat itself does not have any taste. I feel that sweat smells because sweat contains a lot of organic substances, and these substances tend to nourish bacteria, and when bacteria break down sweat, they produce unpleasant excrement.

Summary: The little common sense ingrained in our minds is actually wrong, so hurry up and correct yourself and your friends.
