I don't understand why.  Isn't argyria really rare?  How many of us are on this 
list, and how many have argyria?  It would be interesting to see the results, 
but I bet there aren't many!  And given people's fears, I know for certain that 
if I told the people I know who are taking EIS that they could get argyria, 
(even if they only take the smallest amount) then they *wouldn't* take it, and 
would lose out on all the benefits. I don't think its worth this for such a 
remote possibility, especially as argyria is not life threatening and 
reversible.  Also, I can't understand why if people start to get a tinge of 
colour, why they don't stop taking it?  dee
