@nazokiyoubinbou @eniko Agreed.
It is hard for most people to recognize and understand that we live in a biological soup that we cannot see or directly sense, and that includes but is not limited to viruses, prions and all the other bioactive stuff floating around in air and water. We are not separate from our biosphere, not even inside a Class 10 clean room.
Secondly, people donβt easily grasp that this means all that stuff is already in our bodies, even becoming part of us (like ancient virus DNA). Mostly, our bodies manage pretty well. But now we have new challenges to our immune system, for example. To stay resilient and healthy, we need to help our bodies out by limiting our exposure, limiting the amount of crud inside us so our bodies are not overwhelmed or subverted (as with COVID-19).
