To begin with I am 80 and according to my pulmonologist my FEV1 says I am at stage 4. He has told me (just a month ago) that he has patients at my stage in beds in hospitals and nursing homes. But having said that, if you and I were to take a "walk around town" with me you would not know I had emphysema unless I told you. I can make beds, take showers and (on level ground) walk as far as I care to. This is because I do not "worship" at the alter of western meds and big pharma. I look at things from any and all parts of the world. I take and use whatever I feel is valid from whatever source.
I have been following with great interest the research being done in the field of vitamin A and emphysema. The theory (and question) is why does emphysema continue to progress long after the original causation has ceased? (i.e. smoking for example. My emphysema showed up 30+ years AFTER my LAST cigarette!) But "why" we ask. After all, it's NOT driven by a bacteria or a virus! Scientists now think they know. They now think that smoking for example is merely the "trigger" action and ANOTHER culprit is to blame. That culprit being vitamin A deficiency!
I personally intend to act on the information presented in this British (I think British) web site: oxygenworldwide.com/news/ar...
I intend to do it safely WITHOUT the use of store bought artificial supplements of any kind.
Finally I'd like to state that I am only sharing my beliefs and research. I am NOT advocating anyone do, or not do, anything. Anything anybody decides to do, or not do, is strictly their decision and responsibility.
