Folks come to these forums (I really believe) for assistance to regain their health.. or to secure the well being of a loved one.
Several of us have traveled a "winding path" towards healing.. and the path is crawling with predatory asps, differing opinions, contradictory information..etc...
Most new comers will indeed ask all of the questions that have been asked before (they are new) .. and may challenge the wisdom associated with what the proposed solution really is.
This does not detract from the usefulness of the forum... I think it only enhances it !
Several folks have doubts.. and want to be re-assured before taking another dead end path... that's all.
