You are nature Richard. Nature is you, Just as much as trees, elephants and chickens. You are coming at the subject of health on a completely different path to me.
The body has evolved to do basic things. Protect itself, grow, reproduce and then protect the babe; as it was itself protected.
Given the tools, the body will maintain itself to keep in the best of health. It will heal itself, and whatever it does, is for the goodness of itself. When symptoms arise, they are the body putting right something that is amiss.
The white-coats would have us believe that there is an entity, called a virus, behind every tree, round each corner, just waiting to pounce. And of course if/when they do, a vaxx, created in a factory will sort it. I don't subscribe to that view one little bit.
You can insult me all you want, but the truth is there for anyone to see. Just have to open eyes and mind. But I will say Richard, that you do attempt to discuss; unlike some others.
Nature has the answers we seek.
