Mojo,
I do not believe just in one source, reputed or not yet reputed. I do not doubt many sources telling the same, reputed or not yet reputed. I got many informations matching with my understandings (logical or otherwise) & TRS theory from both reputed or not yet reputed sources which satisfies to me, even though not yet got matched by reputed ones. Don't expect everything is/can be "absolute" in "reputed ones". Many or most things are still unclear as you can find in all reputed medical informations, books etc. We are humans & gifted by Nature/GOD --a brain capable of dynamism & creation, not just a computer. We are made to do & creative, not just follow.
How can mucus make you tall or short, strong or weak, deficient or excessive in body? How it can be one of the prime controlling mechanism with systematic effects of body's controlling system/immunity etc.? Whether it is related to all sensory organs apart from its known role in respiratory, digestive & reproductive systems?
eddited to add;
Whether mucus is related to give effect to constitutional, inherited & chronically aquired manifestations? How & why it become thin or thick, sticky, stringy or otherwise?
