Chapter 51 51．Is the human skin dirty?

Q dream small garden asked I am a mild clean freak, and the fastest daily necessities in our household are hand sanitizers.If someone else touches my stuff, I will definitely wipe it again.For example, if the part-time workers wiped my table and my bottles and jars, I would wipe them again with wet paper towels.I want to know, if someone "touched" my thing, what would be left on that thing?his fingerprints?Dead cells from his skin that had sloughed off?Are these things left behind dirty? A Blue Maple A dream small garden Hello, I'm Lan Feng from the Science Squirrel Club. I just saw a patient. Can I shake hands?Just kidding, but my answer might be too much for you.Therefore, please read the following text carefully accompanied by your partner or guardian. If you feel uncomfortable, please follow up for help in time.

From your description, I seem to see a hardworking and beautiful housewife, wearing home clothes all day long, holding a mop pole, fighting from the bedroom to the living room, from the bathroom to the terrace.Of course, I am very happy that it seems that your cleanliness did not cause you excessive panic, and you did not have the symptoms listed in CCMD-III such as extreme anxiety, doubt, and rough self-judgment, so you are just cleanliness , and did not suffer from obsessive-compulsive disorder.And if you make good use of your slight cleanliness, you may also bring a very healthy, comfortable and tidy home environment to your family. This is a good wife that many men dream of.

Then let’s talk about your problem. You want to know what will be left after someone “touched” something.Then it depends on how you "see" people.Intuitively, we are a whole made up of a piece of skin and flesh, but under a high-powered microscope, we are actually giants composed of various small cells one after another.Under normal circumstances, an adult of us will have hundreds of trillions of cells. Through special bonding methods, these cells are either densely packed or swim leisurely, forming our human body.In this way, the epidermis of our hands is naturally composed of some cells. These cells are called keratinocytes, which are doing their best to resist friction, prevent the leakage of body fluids and the invasion of chemicals.However, it also undergoes apoptosis, and when it dies in battle, it will slowly leave its comrade-in-arms—our body.As for where it lands, it's all a matter of luck.So, it is very likely that you will leave it to me when you "touch" my things.

In addition to the ones you are worried about, the other invisible ones are some bacteria.When it comes to bacteria, I can recommend you to watch the classic blockbuster "Old Stories of Bacteria City" by the Science Squirrel Society.Simply put, the number of bacteria in the human body can reach about ten times the number of cells, and the total weight is only three or four catties.There are beneficial bacteria and harmful bacteria in it, and there are even two-faced people who wait and see.Speaking of this, a recent study, Professor Martin of New York University, believes that due to the excessive use of antibiotics by humans, some bacteria passed down from our ancestors have been strangled, so... We have become obese sadly.So, sisters who want to lose weight, you need to treat the bacteria on your body well.Not to mention the bacteria on our hands, there can be dozens of millions of bacteria on our hands, and billions of bacteria can be hidden in one gram of nail stains. It sounds like you don’t know if you will be full of goose bumps land.So, even washing your hands won't completely let them leave you.Of course, unless there are some deadly and harmful bacteria, the inheritance of countless generations of human beings has allowed our cell populations to coexist harmoniously with these bacteria, so don’t worry, they are actually the same as us, but smaller a little.

As for the other things in your hands, those that can be seen, I don't think you will be afraid.What about dirt and stains? Many people, like you, worry and fear nothing more than invisible and unknown things.Then get to know them slowly, next time you will tell me whether they are dirty or not.
