Thank you for the responses. Obviously I made a couple of mistakes. The version immediately before yours did have some gaps and problems that I overlooked. I guess the sentences, ""The social implication of viewing ageing as a disease could be profound, though this classical is not yet widespread."" and "" Lepers were a group of afflicted individuals who historically shunned and the term ""leper"" still evokes social sigma. Fear of disease can still be a widespread social phenomena. Yet not all disease evoke extreme social stigma.""  made me think you were not a native english speaker because of the multitude of simple number and agreement errors as well as the awkward structure and unusual word use.

I was trying to get rid of the false distinction between disease and syndrome and linkage of symptom to syndrome. A syndrome is simply a combination of problems (not just symptoms in the accurate sense of subjective complaints) often observed together and presumably related. Whether a condition is called Smith disease or Smith syndrome is more a matter of historical contingency than any meaningful denotative distinction. It looked like you were reasserting that and I was trying to get rid of it. 

I put it back the way you left it as I don't feel up to a rewrite. Sorry for any offense.  "
