         "false"??  How do you know, James?  You still have refused to 
present us with your CV.  What makes you think you know so much about 
genetics and about mutations?  (I always thought you were a phrenologist.)

         How large was the dose?  Remember, the dose makes the poison.  And 
how many humans take doses that big (adjusted for weight)?

         More of James' slanders of CHPs.

         Still more slanders.  Besides, if JS's "conflict" is the 
Russian-Georgian war, he still hasn't shown that DU is so much as being 
used there.  Hence his arguments about it are worthless.
