but, getting back to your concern about lead, dubya, dubya, i don't think you have much to worry about.. your mind still seems very sharp, and the other most common symptom is irritability-- a trait i have not noticed in you.

when questioned about irratability, my friend with lead poisoning answered Yes!-- when asked the symptom onset, he replied Age two.( his lead poisoning was directly related to refinishing all the woodwork in his old house, and total adult onset!)
