Hi Steve,
So, the more pertinent and telling question is - by JWs own past reckoning - how many people who were ages 13 to 16 at the time the War broke out are still alive?None. Absolutely none. There are three periods that the "generation" teaching mentioned:
15 or above at the time WWI started. - None left
10 or above at the time WWI started - 6 left
Had been born when WWI started - look at the counter to see an estimate of how many are left.
