Hello, I am a dentist, Park Mira, and I am a person who pursues the truth.
Hello, I am a person who pursues the truth, Kim Young-shin.
Why can't we get rid of all the germs, and why can't we get rid of all the germs?
Have you ever seen an ad for washing detergents that get rid of germs?
Yes, 99.9% sterilization.
That's right. 99.9%.
Have you ever thought about why it doesn't say 100%?
I don't think I've seen 100%.
Even if there's only one germ left, 2, 4, 8, 16, 36.
Oh, I got it wrong. 36.
Anyway, 1024 increases by 2.
So the growth rate is very fast.
To make it completely sterile, facilities and costs are required.
There are also spatial restrictions.
The human population is increasing one by one, but germs are increasing very quickly.
Because germs cannot be killed 100%, there is no detergent that advertises 100% sterilization of germs.
So even if you do laundry, germs will come back?
That's right. If the laundry doesn't dry at the right time, germs will spread and smell.
So we create an environment where germs are difficult to live in, a dry environment, to make it safer.
Oh, that's why you use a dryer.
That's right. Dryers are used a lot these days.
Then why is it not good to get rid of all germs?
Have you ever heard of polyps?
Yes, I know it's a germ that lives in a human body.
As expected, you know a lot.
About 3kg of human weight is a germ.
Oh, that much? Oh, my God.
When I was in class, I was really surprised because there were so many of them.
I thought, oh, if I get rid of germs in my body, I'll gain 3kg of weight.
Oh, I know. Oh, my God.
But if there are no polyps, people die.
People die?
People don't die from germs, but they die because there are no germs?
Yes. It's a different story if there are too many polyps or if the immune system is too weak.
In general, polyps live with humans and protect people's bodies.
It's like a crocodile and a crocodile bird.
That's right. I learned the same metaphor at school.
In addition, polyps also help the function of the human body.
For example, you've heard of colonic germs that are necessary for digestion, right?
Yes, I've seen an article about a stomachache because of colonic germs.
Colonic germs are parasites that harm human intestines.
These parasites help digestion and absorption.
Isn't it because of the colonic germs?
Yes. If there are too many colonic germs or if it's someone else's colonic germs, there's a problem.
In general, if you take antibiotics to the colonic germs and they're all dead, you'll have diarrhea.
When I was young, I used to have diarrhea when I took cold medicine.
That's why we prescribe probiotics together.
If the composition of normal bacteria, called normal bacteria, is destroyed and does not recover, you may die from diarrhea.
Oh, you're going to die? Because there are no colonic germs?
Yes. In fact, in the United States, about 20,000 people die from diarrhea a year.
So it's that dangerous if there are no colonic germs?
So we also treat healthy people's colonic germs by transplanting them.
That's how we save people's lives.
Transplanting colonic germs?
We do a physical examination first so that we can grow healthy colonic germs.
Then we adjust the timing so that we can continue to make healthy colonic germs.
After that, we donate the bowel.
Then we dispose of the bowel well and transplant the healthy colonic germs to the patient.
Oh, my God.
If you eat, no matter how much you eat, you'll get diarrhea, and those who couldn't absorb nutrients will absorb nutrients again, saving lives and gaining weight.
Oh, it's this important. I didn't know colonic germs were this important.
But these are colonic germs.
That's right. But normal bacteria are not only in the colon, but in the whole body.
So they're applied in the same way.
So it's the same for general bacteria?
Of course. You have to live well for all the general bacteria to live well for you.
If you remove all the general bacteria, there will be a problem.
So you're probably wondering if I'm telling you to remove the germs or not.
Next time, I'll explain how to remove the general bacteria.
I want to hear more.
See you next time, everyone.
See you. How can I hold it in?
If you're curious, hold it in.
Oh, episode 10 is already over.
I thought I should smile like that, too.
If you smile, your face really changes.
You have to smile.
I have a face that can't smile when I smile, but I have to smile when I count.
It's really like that when you concentrate.
