Yes
So why is it different in the case of covid? Isn't limiting spittle n such part of it?
COV-2 is a virus. Like influenza flu is a virus. A virus is not a living organism, like say, bacteria. Bacteria is a type of parasite, it invades a host, reproduces, and becomes a health threat. Many types of bacteria live in spittle and sneezes.... hence, the masks. This is called germ theory. But a virus is not much more than a strand of messenger RNA wrapped in a protein. It is not living organism, it does not spread by germ theory. Viruses are produced by our own cells. Viruses are not alive, they do not invade the human cell and take over the mitochondria, they are in fact, taken in by human cells and the mitochondria receives the messenger RNA the same as it receives gazillions of messenger RNA from the DNA, and the mitochondria manufactures more of it, that's a normal process of life. That is happening in every one of your cells right now. That is not the same program as germ theory.
So we become susceptible to viruses when we are weak for any reason. Our immune system kicks out anti-bodies to counter the virus... or so the theory goes. Does anyone really understand what the human body is doing? Does anyone really understand what is happening at the molecular level? Just because we can see a tiny fraction of that world under a microscope, don't buy into the idea that science understands that whole world. We isolate and categorize various chemicals, and we now have a library of thousands of antigens, so we are so capable, eh? Never mind there are trillions of DNA combinations left to learn about. Even trillions of trillions. And then there is that mystery of life... where is the mind of the DNA? How does the DNA know how to react to its environment and decide which of its trillions of trillions combinations to put together to counter act forces outside of the cell? Because DNA does that, we used to think it was just static code for reproduction of the species and it was all hit and miss with traits, but now we realize that DNA is alive and reacts to its environment and that's how we get antibodies. But again, there's a difference between messenger RNA sent to the mitochondria as instructions to build antigens to combat parasites, and the parasites themselves. Bacteria is the parasite attacking the body from without. A virus is just another strand of messenger RNA within, used to combat threats. We are still learning how a virus works or what a virus is... but it is like a malfunction in the immune system. It is a shared behavior of our immune systems. These viruses are actually a reaction of our own system. It isn't germ theory, and it doesn't spread from human to human by germs. The Spanish flu popped up all over the globe simultaneously in a time when it took weeks to travel from the USA to South Africa. Viruses are a completely different phenomena than germ theory.
Wearing a mask for 100 days is a total waste of time. About all it will achieve is actually hurt out health by giving bacteria the body is ejecting through our mouths a 2nd chance to re-enter us... because the bacteria will be stopped by the mask, that's what the masks are supposed to do.
