Very sad but it all depends on the quality of life, 85 is not too bad.
I think the time for the WT society to change their stance on 607/1914 has long passed. After all these years they could never face their members if they made such a doctrinal change. Their last opportunity was the Oct/Nov 2011 with the two part article "When was Jerusalem destroyed?"
The same is true of evolution. They are still telling their school children to challenge their teachers and it all started 6,000 years ago with Adam & Eve. Despite it being a lost argument they will still hang on, unable to admit they were wrong all these years and that evolution is fact.
