I'm not going to debate you, Dragline, but I will say that I disagree to some extent, as I know the difference in ears ringing and ears NOT ringing. If the ears are ringing for several minutes, and yet at other times, acute hearing is not lost, SOMETHING was different, call it what you will. And I believe that something protects the hearing on those occasions. (And though you may use different terminology, I figure adrenaline plays a part...)
Don't invest in idiots....the market's flooded!!!
