I've stated it here previously and will do so again for those that missed it;
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. He graduated High School in 1980 (17 years old) That makes him 60 today. He would have needed to be annointed prior to 1992. By early 2030's he'll be staring at his own mortality. As will any other "Overlapper" of the same age or appointed since. This will predicate a new definition of "this Generation" or a change in the Start / End date for the Gentile times.
