Excluding the currently active normal vaults (101, etc etc)...
How are the other Vault survivor's still ALIVE? First of all, let's just say Gary.
How are the Gary clones still alive? It's been 200 years since the bombs dropped, they should all be dead by now. The same for the Vault where they pumped drugs into it. I could believe that the insane survivors had kids with each other and so on, I suppose, I'm just wondering if anyone else has an opinion on this or agrees that it's a bit weird. I looked around for any other ideas on this, and no one seems to have brought it up. Am I missing something?
