If this was true then the CoQ rats should have had a shorter maximum
life-span than the controls, but they did not (I gather from your 
report).  Since the CoQ rats had a longer average life-span, but the
same maximum, it sounds like CoQ is all positive in regards to preventing
early death, but does not effect the overall life-limiting mechanisms.
