     Andy - part of my last message was not kept, for some reason. I began with 
     a paragraph in which I said I appreciated your definitions, which
     were quoted below. I accept that biologists working on cell division 
     call cell lines that do not stop replicating to be 'immortal'. I am 
     also a biologist, and would rather define 'immortal' (if I would use the
     word at all) for an individual cell or an individual polycellular orga-
     nism. The word immortal, however, is not very exact as it is not easy to
     prove.
     
     Thank you for explaining the terminology of biologists working on cell 
     lines. It clearly helps the discussion.
