Recently there are always some strange and bizarre ideas, perhaps breeding for a long time, just do not have time to organize it, perhaps some absurd, as thinking is not guilty, write it down. I often think about the bacteria that live in our gastrointestinal tract, they may have lived there for generations, living their unique life in their unique way, the gastrointestinal tract is their whole world, they also have generations of reproduction, they also have happiness, sadness, they also have life, old age, sickness and death, seems to be the law of life is destined when the origin. If one day accidentally run into the hands of people, like to another planet, wow, there are aliens it (met the hands of bacteria), leaving the human body is like we left the earth, was thrown into the unknown space of the universe, maybe will die. Bacteria must have a mind, but will he be aware of the existence of humans? Taking some antibiotics when humans feel sick one day would be like a sudden plague or an unpredictable natural disaster for them, right? I also often imagine tumors and imagine their world. To distinguish ourselves from other species, we call ourselves humans, and because of the infinite growth of certain cell clusters, we call them tumors. Perhaps we humans ourselves are also a kind of tumor, growing without limit, developing without limit, destroying and changing our environment without limit, perhaps these natural environments are the tissue fluid we live on, and when we develop and destroy to a certain extent, some bigger species we are parasitic on will have to start treating us, unleashing tsunamis to slap us to death, holding floods to drown us, shaking our bodies hard (earthquakes However, the tsunami did not kill many, the flood did not drown many, the earthquake did not shake us all to death, on the contrary, after surviving these disasters we learned how to take refuge, just like the little Japanese house under 7 earthquake how to shake not fall, if more profound, we will realize to live in harmony with nature, convergence of our brutal attack, will get a temporary peace, but Mankind can never stop moving forward, just like a tumor cell, development is his nature. If there was a louder voice telling us how mankind should develop to be harmonious and long-lasting, after several disasters maybe we would listen and accept, but there is no such a voice. Just like we don’t know how to educate our tumor, how to say to it: “Hey, breast cancer cells, I’m talking about you, you have to stop, if you go around again, I should have chemotherapy”, there are really desperate tumor cells that end up with their parasites. Maybe we should find a better way to communicate between human and tumor. I don’t know what I’m talking about, maybe these are called conjectures, the reason why I wrote this down is that I think our medicine is gradually moving from macro to micro, the understanding of life is getting more and more fine, it has come to the molecules inside the cell who and who are how to communicate, this is a kind of progress, but maybe in addition to micro research, you can jump out and look at the macro to see our whole, maybe there will be some epiphany.
