"Okay, Xiao Langlang, you are honest now, where did the clothes you wear come from?" Yin Yuting looked at Wu Lang with disgust and said.

"Sister Yan bought it for me. Wu Lang told him what happened in the hospital today.

"I'll forgive you this time, you are only allowed to wear the clothes I bought in the future, otherwise I will pull your ears off. After Yin Yuting finished speaking, she smiled and kneaded Wu Lang's ears.

"Tingting, I thought you would be so violent that you tore my clothes, I didn't expect you to be so generous and open-minded!" Wu Lang looked at her in surprise.

Yin Yuting looked at Wu Lang's exaggerated expression, glanced at him, and said: "Look at your pretentious appearance, I'm not as stingy as you think, you are the reason for work, Li Yan'er is in the care of colleagues, but there must be another purpose for you, let you follow her to learn administrative management during this time, it is the naked heart of Sima Zhao, but Miss Ben is full of confidence in herself, and she also trusts you well, it doesn't matter, just let you go, as long as you belong to me physically and mentally." After speaking, he grinned and grabbed Wu Lang's two ears and kept pinching.

Hahaha......

Yin Fat Man and Shang Minjie couldn't stop laughing when they heard this, and Wu Lang also shook his head while laughing, dodging her hands.

After a long time, Wu Lang looked at Shang Minjie and said with a smile: "Xiao Wen, you are engaged in human life science research, is it possible for human beings to achieve immortality in the future?"

After Shang Minjie listened to Wu Lang's words, she also smiled: "It is the instinct of all living beings to want to survive longer, but when a creature survives for a longer time, the weaker its ability to resist various accidents in the outside world. Human beings are different from other animals in nature, human beings have the ability to recognize themselves because of sufficient intelligence, so many human beings will look for their own ways to prolong their lives, in ancient times, many people used various methods to prolong their lives, but unfortunately, from the currently known data, no one can succeed, there is a Bafeng coefficient here. ”

"Xiao Wen, what is the Ba Feng coefficient?" Yin Yuting asked curiously.

Shang Minjie took a sip of tea and said with a smile: "For example, a dog's one year old is about equal to 18 years old for humans, how did this statement come from?" In fact, this is the Bafeng coefficient, the life limit of mammals, in fact, it is related to the growth cycle, the faster the body development cycle, the shorter the life expectancy, in general, mammals can achieve, their own growth cycle time 5 to 7 times the lifespan, and then take dogs as an example, the growth cycle of large dogs is about one and a half to two years old, and the life span of most large dogs is about 14 years old. This wind coefficient is common in mammals, so it is also applicable to humans, we know that human beings are basically complete at the age of 18, if calculated according to this method, then human life expectancy should reach 140 years old, but unfortunately few people can reach this age. ”

Wu Lang picked up the wine bottle, took a big sip of "water of life", took another deep sip, nodded, and quietly listened to Shang Minjie's explanation.

"Human cells can divide, but there is also an "upper limit" for this division, if the cell can divide indefinitely, then human beings are equal to immortality, but unfortunately human cells have an upper limit of division, and because of age, cells will lose activity and water, scientists found after experiments that human cells have an upper limit of division, about 50 times, which is the same as the "telomere" on our cells Related, each cell division telomere will become shorter, which determines that our cells can not divide all the time, the division survival cycle of each cell is about more than a year, combined with the upper limit of 50 times, it is concluded that about 120 years old is the limit of human lifespan, the average life expectancy of human beings may be more than 120 years old, about 140 years old, from the record of the world's long-lived old people, it can also be seen that this number is still relatively accurate, this answer makes people sigh, because this has a lot to do with the existence of entropy. After Shang Minjie finished speaking, she frowned slightly.

Wu Lang was stunned for a moment and said: "I have seen the word entropy in books before, but I don't understand the specific meaning, so let's popularize it for all of us!"

Shang Minjie nodded: "All living beings on the earth will go through a process of growth, from infancy to old age, and finally die for various reasons, this process is irreversible to us, everything in nature will change from an orderly entity to a disordered nothingness over time, simply put, everything in the universe will disappear over time." In fact, in physics, there is a physical law that gives the answer, and also tells us the end of the universe, this law is the "law of entropy increase", we can see the end of the universe from this law, entropy is a physical concept, representing a closed system, the sum of the degree of chaos, the universe we are in is a huge closed system, simply put, entropy is "decay", any object in the universe will "decay" with time , but this does not mean that the object has disappeared, but has only changed its form and still exists in the universe. For example, if we burn a piece of wood, the process of its burning is a process of continuous "entropy increase", the wood itself is a closed system, after burning, the wood is converted from its own structure into heat and gas, and finally a piece of coke is left, the original "orderly" charcoal has become disordered heat and gas, and the charcoal left behind is more "disordered" than the original, for the universe, the energy represented by wood has not changed, but has become "disordered". ”

Wu Lang was shocked when he heard this, frowned slightly, and listened carefully to Shang Minjie's explanation while thinking about other things in his brain.

Because of the existence of the law of entropy increase, the closed whole of the universe may slowly turn into a disordered void over time, under such a premise, life cannot achieve "eternal life", because the universe cannot exist forever, after losing the cosmic space on which we live, we will have no substance, and the meaning of eternal life will not exist. The birth of life, the universe in the future, may appear other possibilities, because the meaning of life itself is "entropy reduction", if there is a living organism that can achieve the theoretical "entropy reduction", then can it achieve eternal life? As far as the current research is concerned, the answer is also no, the aging of life itself is a process of "entropy increase", if the entropy is successfully reduced, this organism will become more and more "orderly" But the problem arises, life is slowly growing from tiny cells, and finally becoming life, this process can also be seen as entropy increase, if life reaches entropy reduction, it will only become a cellular state, and finally disappear. So logically speaking, life can never achieve "eternal life", but the meaning of life is to slow down the "entropy increase", but can not achieve the "entropy reduction", otherwise the opposite effect will occur, from this point of view, life is more like the silent struggle of the universe itself, to a certain extent, slowing down the "entropy increase", but life is too scarce in the universe, just a drop in the bucket. After Shang Minjie finished speaking, she shook her head and smiled bitterly.

Yin Fat Man put his arm around her waist and said with a smile: "Then there is no way, for example, to keep a person's body and mind at a glorious age of about twenty-five years old forever?"

Shang Wen glanced at him: "How can there be such an easy thing, some things are just theoretical, but it is difficult to find a practical and effective way, human beings, the emergence of diseases and cancer, is a good "entropy increase", with the increase of time, our body will become more and more disordered, some disobedient "disordered cells" appear, and finally lead to the death of life, but we can use drugs to alleviate or even cure diseases, this is a certain degree of "entropy reduction" The meaning of life itself is to resist "disorder" in order to prolong its existence and reproduce at the same time. ”
