I see Waton posted a possible time line. He likes the perfection of 2075. I think this is too long. I thihk we have a significant change in the next 10 years.
I use Ken Cook as a model
The wt 1914 generation is not only about the GB, as D. Splane stated, but about any of the anointed Class.
any 20 year old that had the anointing potential could have worked with Fr. Franz or the like (as I did) before his death, and still carry on today. She would be only 48 years old today. ( I am nearly twice that age). The potential super centenarian "overlapper" that D. Splane mentioned would be only ~ 100 by 2075,
If wt would revert back to the natural lifespan,generation 1914 + 118 would give them 2132, so
that are the current upper limits, The "soon," last days are" are wt diversions.
Rev 11:18 is the only realistic trigger for a quieter planet. the math is in the missile algorithms.
