I'd say that there are likely scarcely any individuals who were old enough to comprehend the significance of events unfolding in 1914 who are still alive, including JWs.
Ah, but lest we forget the Great Oracle FWF was alive then and did not die until 1992 (?). By that chart that Splane 'splaned" things with if one were to consider 14 years of age the age of comprehension someone born in as a JDubya in 1978 could possibly be part of the "over-lapper" class. And they could be "anointed" by H.S. (Holy Suggestion) of the current anointed ruling body, like the new kid on the block. If that happened they could be as young as mid to late thirties or early forties. That buys "this generation" another possible fifty years or more. Of course by then WE will all be dead, and no one else will be around to contradict whatever drivel THAT bunch of over-lapping over-lapping over-lappers will trot out as their definition of "soon".
