I liked how you hit upon the advantages and disadvantages of making something disappear forever. Not a fan of this giving everyone a bionic heart though. Very creative! :)

A very fun post-apocalyptic description. An eerie last line, brings it all together. I feel the fourth and fifth paragraphs don’t flow as well as the rest, but I’m not sure why and that could just be me.

I question how early it is, 2025? Only 15 years away, the scenario doesn’t seem possible. Though I realize I’m trying to apply logic to fantasy.

Highly creative and wonderfully engaging!

Wait, the twentieth century guns lasted longer than the twenty-first century guns? They just don’t make ’em like they used to!

Oh no, that’s just me getting my centuries mixed up. I’m just a big idiot really.

Wow, brutally tragic. Nicely conceived, even if I don’t think we’d ever stop finding reasons to kill, immortal or not. Great job on the challenge.

Everyone in charge of that project should have read/seen Tuck Everlasting.

Anyway, good story!

Very clever..
