If you haven't seen will forte's "the last man on earth" on Amazon prime, do as its really funny. The setting of the story is that 2 years prior a virus has killed all humans except one...

It's got me thinking, all the wt's illustrations show the time when Armageddon is over as being really joyful and there being plenty for everyone. But in fact that would just not be the case, especially since most jw's have no survival skills or expert knowledge of any kind.
Jws just don't think about this, how are all those couples who are waiting untill the new system to have kids, going to have kids in a survival setting? No drs no stand by if anything goes wrong etc.
And those jws who are waiting until the new system to get married... well there's a lack of decent mates available now, what about when half of them are dead cos their heart condition wasn't quite right? You might end up having to settle for brother pervy weirdo!
As always I make the disclaimer that I'm an atheist, but its fun to debate these beliefs, helps to deprogramme ourselves.
