Welcome to the world of advertising. They have researched and know the buttons to push to pull people in. And if a person has been so conditioned to think that the "only" way is through the medical community, which is a very strong presence, what can you expect. They feel at their mercy. We are also a get "quick fix" society, nobody wants to wait for anything anymore. I even find myself guilty of that in some areas. Just fix it! I don't have time for anything. That is sad.
The part of the comercials I love is when they start listing the side effects, I sit there going - who in their right mind would want to take that!
Per Louise Hay, Arthritis probable cause is "feeling unloved, criticism, resentment", and joints (which is usually what is effected) "represent changes in direction in life and the ease of these movements".
