I have often read this quote as being by Mark  Twain.
 
I'm convinced, however, that's not the case.  Barb Schmidt would  have
included it on _www.twainquotes_ (http://www.twainquotes) .   And it's not 
there.  Or if it's there, I'm blind 
and haven't seen it.
 
Should anyone have any convincing evidence otherwise, I'm pretty
sure it will surface here on the List.
 
Best,

I have  seen this attributed to Mark Twain:  "Age is an issue of mind over  
matter. If you don't mind, it doesn't matter."  My questions are:   Did MT 
originate this quote?  Or, at the very
least, did he at some  time say or write it?  If not, is the source known?
