Just like singing in a song, everyone has a grassland in their hearts, where the grass is green and the red flowers are gorgeous. Surrounding the boundless world of grassland, people are always relaxed and happy, with long-term sentiments. Even if we have never been to such a vast prairie, if we go outing in the suburbs, we will be involuntarily immersed in the fragrance of grass.
In the past, the pleasant, peaceful, and healthy mood produced by the grassland was considered unreliable and unscientific, and was exaggerated by fairy tales, novels and poems. However, it took a long time for scientists in biology and medicine to come up with a new point of view: Our body is dominated by microorganisms. These microorganisms are as vibrant as lawns in spring, so in our bodies, there will be grasslands. Characteristics and memories.
Microbes control our body
Scientists say that our body actually has a developed ecosystem. Without this ecosystem, we cannot decompose and digest food. In this system, microorganisms play a vital role.
Microbes are completely dominant in healthy humans: out of the 10 billion cells in our body, there are 100 billion microbes that play an important role in our metabolism. This greatly increases the choices in the process of our body's survival and reproduction: if we include the genes of microorganisms, then there are more than 100,000 genes in our body, not just more than 20,000.
American microbiologist Bruce Billen concluded: "Our body is a colony of bacteria." Our body is occupied by microorganisms. Different colonies develop in different body organs, especially in the intestine. The metabolic process plays a vital role.
The type of bacterial ecosystem in the intestine will determine to a certain extent how successful we absorb nutrients. For example, when children from the independent state of Papua New Guinea in Oceania are born, they carry a nitrogen-fixing bacteria in their intestinal tissues. This bacteria is generally found in plants and algae. With the help of this bacteria, even these children have been vegetarians for many years. , And there will be no symptoms of malnutrition; people with obesity tend to have a particularly effective digestion of bacteria, just a bite of the biscuit, they can absorb all the nutrients in the biscuit, and the food eaten by the thin people is passed through the digestive tract. Not to be absorbed.
Not only the metabolism, but the balance of our neurotransmitters and hormones cannot be completely controlled by our brain and body. Scientists believe that whether a person feels happy or not may also depend on the bacteria in the body.
Man and the grassland are integrated
Looking at the grassland again, the microbial "biofilm" covers the wet surface of the grassland. Hundreds of microbial species entangle, swallow, eliminate, extract and synthesize substances. This is actually the same as the operation of microorganisms in our body.
It can be said that the communication relationship between people and the grassland means that we are part of the grassland landscape. The moment human beings got food from the grassland in the early days, they also integrated the grassland and its inhabitants into their bodies and genes. Therefore, when we are in the grassland, not only can we perceive hundreds of plants and countless insects to form the grassland ecosystem, but we will also regard ourselves as part of this scene.
Similarly, the grassland is a part of our body. It is one of our sensory organs. In the grassland, we can feel things that we cannot understand correctly. The emotion brought to us by the natural world is not just a metaphor for poets and singers, nor is it an arbitrary conjecture, but a feeling that really exists in our body. The sentiment about the grassland comes from the physics of the organic world, and as an individual, only by integrating into the natural world can one achieve true tranquility and joy.
