i belive your right as child my father brought him mercury for us to play with he is a elctriacian this is before it was known to be so bad for you. we played with it in the kitchen. it fell on the floor you cant clean it up. it falls in to a million beads. i do think i am sick because and have been for many years because of this. i also found a way to help myself not feel so sick/ my brothers is dentist and i belive that fillings in your teeth are bad . i know people who have had them all taken out and felt much better once they were all gone. sky
