I totally agree with Demi, I don't think anyone is unaffected by mercury, sooner or later it's devastating effects will rear it's ugly head in one way or another....here is an article on the 3 degrees of mercury toxicity.

"First degree micromercurialism results in lowered work capacity, increased fatigue, light nervous excitability.

Often, in the second degree there is swelling of the nasal membranes, progressive weakening of memory, feelings of fear and loss of self-confidence, irritability, headaches. Simultaneously there may be catarrhal symptoms and upper respiratory discomfort, changes in the mucous membranes of the mouth, bleeding gums. Sometimes there are feelings of coronary insufficiency, shivering, quickening pulse, and a tendency towards diarrhea.

Third degree micromercurialism is characterized by ... headaches, general weakness, sleeplessness, decline in intellectual capacity, depression. Among other signs are tears, diarrhea, frequent urination, a feeling of pressure in the cardiac region and shivering."
