Yuan Shichen smiled slightly: "You are worthy of being the most famous life scientist in the league! I believe you have noticed it long ago!"

"Haoho~" Dr. Mingqi said with a smile, "Indeed, I discovered that you were unusual in the media live broadcast yesterday."

"Although flying near the speed of light and long-term dormancy will slow down your aging speed, there is still a clear difference in your appearance from another astronaut."

"I also realized this!" Yuan Shichen said frankly, "Maybe everyone else thinks it is related to flying at the speed of light and long-term dormancy, but I don't think it's that simple!"

"Will it have anything to do with Roland's invasion?" Dr. Mingqi asked back. He also participated in the Mars scientific exploration operation with Harashi Naichen. He also knew the background of Commander Roland, that is, Genesis Artificial Intelligence 8.

"I can't be sure of this!"

The invasion of alien artificial intelligence is indeed one of the factors that Yuan Hashichen considered. After all, Commander Roland, that is, Princess Hanyue's body, has actually survived for a long time for 2,000 years.

However, in addition to this, Yuan Shichen also has an option in his mind, that is, the mysterious meteorite energy found in the pool by the Sun and Moon Creek. Since it has the ability to change and strengthen its thinking ability, observation ability, reaction ability and even physical strength, it is not impossible to delay its aging speed!

"You look exactly the same now as when you left Earth!" Dr. Mingqi said in amazement.

"Do you have any great ideas? Please give me some advice." Yuan Shichen asked humbly.

"Can you contribute some blood and a little tissue cell to me?" Dr. Mingqi asked suddenly without answering his question.

"This is no problem." Yuan Shichen's mind quickly changed. With his understanding of Dr. Mingqi, he felt that there was nothing wrong with it, so he agreed.

"Haohuo~" Dr. Mingqi laughed strangely again, "Don't worry, we won't slice you and study it!"

Yuan Shichen shook his head with a wry smile, and complained in his heart: "It's indeed a Frankenstein!"

With his ability and status today, he certainly would not worry about anyone who dared or had the ability to slice and study it. Moreover, slice and study itself is a very absurd thing.

From another perspective, if some blood and a little cell can contribute to the research of human life sciences, Yuan Shichen would still be happy!

"Qingchenjun, do you know why humans and most advanced animals age?"

Dr. Mingqi asked while bleeding Yuan Shichen, and the scene was quite strange.

"This is also a scientific problem that has not been finalized yet!" Yuan Shichen replied, "I have read some related books before."

"Jun Chen is worthy of being a super scientist, and he is indeed widely involved!" Dr. Mingqi praised.

"You're too much!" Yuan Shichen took a cotton ball and pressed his pierced arm tightly.

"Do you know, how often do cells in the human body change?" Dr. Mingqi continued to ask.

"The lifespan of different cells in the human body is different. Some cells have several months, but some are only a few minutes or even less. For example, the lifespan of liver cells is 18 months, and the lifespan of skin cells and digestive tract walls is only a dozen days. Some cells can exist for a lifetime, such as nerve cells, skeletal muscle cells, and cardiomyocytes, all belong to permanent cells." Yuan Shichen replied.

"You're right. People of different ages have different cell renewal speeds." Dr. Mingqi added, "According to cell algebraic theory (also known as cell division mathematical theory), human cells are completely renewed every 2.4 years."

"In addition, you must have heard that the replication lifespan of each cell has a certain limit." Dr. Mingqi continued, "We have improved cell culture experiments, but the effect is not obvious. Under artificial culture conditions, even the best culture method cannot change this established destiny. For example, the human fibroblasts can only reproduce for up to 50 generations (according to relevant theories, the lifespan range of humans is about 2.4 years x 50 = 120 years old.), and by then, the cell will inevitably die. Other species, such as mouse fibroblasts, can only divide for 19 generations, and tortoise fibroblasts can divide for 110 generations."

"Dr. Mingqi, you don't want to cultivate my cells, haha!"

"You are right, I'm just thinking!" Dr. Mingqi replied with his eyes shining.

"Then you have to train more generations, which means I can live a few more years!" Yuan Shichen quipped.

Soon, Dr. Mingqi drew blood for Yuan Shichen with satisfaction and retained a little tissue cells. This process was like an ordinary physical examination.

"However, not all cellular organisms are restricted by the number of cell divisions." Harashi Chen asked, "Single-cell organisms such as bacteria and protozoa have been relying on cell division to reproduce and reproduce, and have never stopped for billions of years. It seems that there is no problem of cell aging. Moreover, among higher organisms, there are exceptions, such as germ cells and cancer cells."

The phenomenon of unrestricted germ cell division is strange and easy to understand. Please imagine that the combination of your parents' germ cells gave birth to you, and you are a brand new individual. That is to say, when you were born, the life clock of your parents' germ cells had been accurately turned back to zero, thus avoiding the tragedy that was destined to be twenty or thirty years shorter than your parents.

As for cancer cells, it seems that there is a magical mechanism to help them get rid of the misfortune of final aging. Biologists found in culture that cancerous cells can reproduce indefinitely, generation after generation, and will not tend to aging like normal cells. In clinical medicine, it is precisely because cancer cells are immortal and divide unruly that cancer patients will eventually die.

"This is the wonderful place of life!!" Dr. Mingqi sighed, "The microscopic world of life is as great as the macroscopic world of the universe!"

"The sun is mid-day, the moon is full and the moon is full and the loss is lost. The same is true for personal growth, from weak to mature, and finally to aging. So, how long should human life span?"

Dr. Mingqi is indeed familiar with Chinese culture and is very knowledgeable about citing classics. This is also what Yuan Shichen has a good impression of him.

"From the perspective of nature, although the matter we see is eternal, most things have their own lifespans. Radio elements have half-life, organisms have birth, old age, sickness and death, and even society will have ups and downs. I believe that with the development of science and technology, molecular design and genetic design will become possible. Humans may have the ability to transform themselves in the future, and aging and diseases will be conquered. Perhaps using genetic technology will make future humans stronger thinking, stronger muscles, and more sensitive reactions." Yuan Shichen looked forward to the future of human beings while thinking.

"Mr. Wei Chen, you really dare to think that with our current scientific level, it is already amazing to be able to fight aging and extend human lifespan!" said Dr. Mingqi.

"So, the cells are constantly renewing, why does the human body still age?" Yuan Shichen continued to ask.

"When humans grow old, their hair gradually turns gray, their skin wrinkles, their muscles gradually loosen, and their bones become fragile... All parts of the body are quietly changing. Aging is an extremely complex process. This complexity has led to at least 300 aging theories at present." Dr. Mingqi said seriously, "I think aging is related to evolution!"
