Doctor: start with the heart

Chapter 181 Zhang Guoer's Suspicion?
"Could it be that your goal is like the one written in the novel, longevity or something?"

Zhang Guoer said half-jokingly.

"Do you know why humans have a lifespan limit?"

Zhao Xu didn't answer, but asked back.

"Why? I'm not a medical professional, how do I know?"

Zhang Guoer said.

"In 1961, the scientist Hayflick discovered that there is a limit to the cell division of mammals, and the number of divisions of each cell is limited. He called it the internal biological clock. That is to say, when everyone is born, the limit of life span is It has been determined by genes, the only difference is that some people have reached the limit of their lifespan, and some people have died early due to diseases or accidents due to various reasons. The number of divisions has reached the limit, the cells of the whole body of the human body are dying, and the organs are slowly failing."

Zhao Xu explained professionally.

"Then is there a cell that can divide infinitely? In this case, wouldn't people be able to live forever?"

What Zhao Xu said was easy to understand, and Zhang Guoer understood, but she asked in a whimsical way.

"The cells you mentioned that can divide indefinitely do exist."

Zhao Xu nodded and said.

"Huh? Really? I thought it was my whimsy."

Zhang Guoer said with some surprise.

Originally, she was just talking casually, but even a pure artist like her became interested in what Zhao Xu said, such as longevity.

This is not surprising, as long as you are a human being, you will be interested in things like lifespan.

"A cell that divides infinitely is a cancer cell."

Zhao Xu explained slowly.

"Cancer cells? Doesn't that mean that human beings can't live forever. If they were all replaced by cancer cells, wouldn't they all become monsters?"

Zhang Guoer frowned and said.

"Therefore, it is impossible to extend the number of cell divisions. When human cells divide, they replicate through the telomeres at the ends of chromosomes. Every time they replicate, the telomeres will shorten, and the telomeres will be degraded many times. After disappearing, the chromosome has reached the limit of replication. Therefore, the research direction I envision in the future is to start with the control of telomeres."

"A desk clock, we can artificially adjust the clockwork to make it faster or slower. Similarly, the life clock can also control the speed by controlling the length and shortening of telomeres, and can even go forward or backward. Since the number of divisions If it cannot be changed, then try to extend the interval between each division as much as possible, as long as the interval is long enough, then the lifespan of human beings will also be extended."

Zhao Xu explained his future research direction in detail and professionally.

To study the control of telomeres on human cell division is not simply the workload of preparing endorphins.

To complete this work, the prerequisite is to draw the human genetic map, and then we can start to study how to regulate the division of cells in various parts of the human body through telomeres based on the human genetic map.

Depicting the human genetic map is a very huge project. Even if Zhao Xu develops artificial endorphins and earns tens of billions a year, all of these are invested, and it may not be splashed at all.

In fact, in the 80s, scientists in the United States had already proposed a human gene sequencing plan. The plan at that time was $30 billion a year.

And now, this number has at least doubled, that is to say, it needs 300 billion U.S. dollars per year, which is equivalent to nearly 2000 billion soft sister coins. This is absolutely unbearable for any person or company in the world, or even any country. Huge research funding.

Most importantly, in recent years, this plan has slowly stagnated.

Because this plan sounds great, but it will not happen overnight to actually produce economic benefits.

What Zhao Xu has to do is to take the lead in starting a part, and then slowly through gene sequencing, produce some results that can generate economic benefits, so as to drive the whole world to participate in this plan.

After getting the system, Zhao Xu couldn't bear the fact that he would die one day.

"Immortality? Sounds cool."

When Zhang Guoer thought about it for a while, she thought it was very cool. Thinking about it, being able to have a young body forever, enough body to do what she likes to do, this is the real paradise on earth.

"It's not immortality, but in this world, longevity is the biggest factor limiting the progress of science and technology in this world. Modern science is too complicated, and it takes at least a few decades for a field to reach the top, but the masters in these fields of science , could have made more contributions to mankind, but because of the limitation of lifespan, it may cause a scientific fault."

Zhao Xu said slowly.

"Your idea is very good, and I support you."

Zhang Guoer said with a smile.

"This plan is too huge, and it may take decades to complete, but the days are still long, so we can take our time."

Zhao Xu is very confident that in his lifetime, he will be able to crack the code of eternal life and allow himself to achieve eternal life.

"Then if you succeed, we can be together forever."

Zhang Guoer thought about it and said happily.

"This... this guest, I have a question..."

Just as Zhao Xu and Zhang Guoer were enjoying their future eternal life, the chef, Master Wang, was engrossed in listening, and suddenly had an idea.

Although he didn't understand the professional knowledge that Zhao Xu said, he did understand Changsheng.

"Huh? Master, please tell me."

Zhao Xu looked at the very burly chef standing behind the iron plate in surprise, not knowing what he wanted to say.

"Just now I heard you guys talking about longevity. I, Old Wang, don't understand those professionals, but I remembered that I heard from the old man that there was a big villain in our past. Everyone had nothing to do with him. We'd better wait for his lifespan to come later. , after death, the village will be clean. If such a wicked person can live forever, then what should we do?"

The chef, Master Wang, said very simply.

Master Wang has been in the society for many years, and has a lot of knowledge, which is actually much richer than that of Zhao Xu and Zhang Guoer.

He listened to Zhao Xu and Zhang Guoer talking for a while, and felt that these two people were too simple and naive, and he didn't know how many villains there were in this world.

"Master, what you are talking about is sociology. We are discussing how to make human beings progress."

Hearing what Master Wang said, Zhao Xu frowned and said.

"Well, well, what you said, guest."

Master Wang nodded, seeing that the big customer who ordered expensive steak and seafood in front of him was a little unhappy, so he stopped asking.

Originally, he just heard what Zhao Xu said and wanted to ask a question on a whim.

If he offends such a high-profile customer, the manager will definitely deduct money from him.

"I'm full, shall we go home?"

Zhang Guoer looked at Zhao Xu affectionately and said.

"go home?"

Zhao Xu hesitated. The last time he stayed with Zhang Guoer, he felt a little weird.

"Could it be that you still take me to open a room? I don't like staying in hotels, and the privacy of staying in hotels is not good."

Seeing Zhao Xu's hesitation, Zhang Guoer couldn't help saying.

"Then go to the apartment where I live. When it is free another day, we can go to see the house together. We should buy our own house."

Zhao Xu thought for a while and said.

The apartment I live in is allocated by the Young Talents Program. The environment and decoration are very good. Although the area is only eighty or ninety square meters, it is actually enough to live in.

"Well, then you can accompany me to the supermarket to buy some daily necessities."

Zhang Guoer nodded. He could go anywhere if he could be with Zhao Xu.

Besides, the two have just completed the most in-depth communication, and now is the time when their relationship is in full swing and their passion is on fire.

In things like playing poker, one has two, and it is also addictive.

After a while, Zhao Xu and Zhang Guoer came to the cash register, ready to pay.

"Doctor Zhao, are you leaving now?"

Seeing Zhao Xu coming to pay the bill, Fan Mei said with some regret.

If it weren't for his real girlfriend to come, she would still be able to stay with Zhao Xu, maybe there would be some sparks.

Zheng Gong didn't dare to think about it, but it's good to be a lover.

That's hundreds of billions, just a little bit of corners and corners is enough for Fan Mei to become a rich person.

"Well, check out."

Zhao Xu nodded.

"Doctor Zhao, the total here is 12420. I'll give you a [-]% discount. Just pay [-]."

Fan Mei quickly settled the account and said to Zhao Xu.

This discount is actually a means of showing favor to high-end customers in the store.

Originally, the profit of high-end ingredients is very high, so a [-]% discount is nothing at all.

"it is good."

Zhao Xu took out his bank card without changing his face, and swiped it to pay.

There are still 300 million in his account, and there will be a steady stream of credits in the future. For ordinary people, the cost of [-] meals is nothing to him.

"Doctor Zhao, you spent more than [-] yuan here, and there is special red wine for you in the shop, take it."

Fan Mei said very attentively again.

If the cost exceeds a certain level, there must be a gift, but this red wine was added by Fan Mei herself. It was originally an anniversary gift that only the highest-level members could have.

Coming out of the store, Zhang Guoer took Zhao Xu's hand and walked towards the parking lot. She came by car.

"Is this car new?"

Looking at the fiery red, streamlined Tesla electric sports car in front of him, Zhao Xu asked with some doubts.

"My aunt gave it to me."

Zhang Guoer said casually.

This fiery red Tesla electric sports car is the most model, and the price is 100 million, but for Zhang Youqing, it is not a big deal to give such a car to his niece.

Zhang Guoer's current promotion to the company alone is not comparable to a car, not to mention Zhang Guoer and aunt Zhang Youqing have been in love with their mother and daughter since childhood.

"Quite good looking."

Zhao Xu looked at the electric sports car in front of him with a streamlined shape, fiery red color scheme, and a futuristic and technological sense. Then he remembered that he didn't even think of buying a car of his own.

When he was in college, he learned his driver's license and even worked as a substitute driver in his spare time. For a man, owning a car of his own is a must!

"Are you coming?"

Zhang Guoer said with a smile.

"Forget it, I prefer to drive an off-road vehicle."

Zhao Xu shook his head slightly and said.

He prefers rough off-road vehicles to sports cars.

After getting in the car, Zhao Xu looked at the imposing Zhang Guoer, who was sitting in the co-pilot and started the sports car proficiently, and couldn't help but think that someone said that she likes to watch girls who drive the most.

I'm afraid this makes sense. A girl's beauty can also be of various kinds. It can be soft or saucy.

Soon, Zhang Guoer drove to the supermarket and parked the car in the underground parking lot. Zhang Guoer put on a mask to cover her face tightly, walked into the supermarket with Zhao Xu, and started shopping.

"I need this body lotion, and this, oops, there are too many things to buy."

In the daily necessities area, Zhang Guoer said while shopping.

This supermarket is considered a high-end supermarket, and many things are imported, so there are much fewer customers than ordinary people.

"Body lotion?"

Zhao Xu couldn't help curling his lips when he heard Zhang Guoer's words.

As a straight man of steel, he has never used any body lotion.

"Why don't I buy some skin care products for you? Your foundation is so good. If you don't take good care of your skin, it will be wasted."

Zhang Guoer looked at Zhao Xu with fair skin, sword eyebrows and starry eyes, and said suddenly.

"I don't have to."

Zhao Xu shook his head slightly. He was not interested in skin care.

"Of course I use it. If the skin is healthy, the complexion will be good."

Zhang Guoer insisted on pulling Zhao Xu and bought him a lot of men's skin care products.

After shopping for daily necessities, Zhang Guoer dragged Zhao Xu to stroll casually.

When passing the health products area, Zhang Guoer stopped and looked at the piles of Neptune gold bottles, kidney treasures, etc. in the health products area, Zhang Guoer couldn't help but look at Zhao Xu.

"Huh? What do you see me doing? Do I need these?"

Zhao Xu couldn't help laughing when he saw Zhang Guoer looking at the health care products and then sizing him up.

"No, you are so powerful, so naturally you don't need these. I'm just curious, can these things really enhance that ability?"

Zhang Guoer is a new recruit, and has developed a strong curiosity about this aspect.

Her physical fitness is already very good. This person has just opened up and entered this field. Naturally, this demand will be much stronger than that of ordinary girls.

This is also very normal. The better the body, the more the demand will naturally be.

But she was also worried. After all, she had heard that a boy's body needed to be taken care of. If it was overdone, it would hurt his body. That's why she thought about whether to buy some health products for Zhao Xu to take care of him in advance.

"Hmm.. I read online that it will hurt your body if you do it more than three times a night..."

Zhang Guoer said tentatively.

Both she and Zhao Xu are in good health. Zhang Guoer has been exercising since she was a child, and Zhao Xu's body has been systematically transformed. No, the two scored three goals in the first night together.

"You don't have to worry about that, even if it's ten times a night, I'm fine."

Zhao Xu said a little speechlessly.

"Huh? Ten times...!"

Zhang Guoer looked at the confident Zhao Xu and didn't know what to say for a while.
