This reminds of Fallout 3, doesn't it:

So, is the naive illustration of "preparation for nuclear war" depicted in F3's pre-war remains really just ironic fiction?
Imagine the impact of a 10 km asteroid on Earth, or an allout nuclear war,. or a lethal global epidemic. Would you book a place in one of these?
What if doomsday lasts longer than 1 year, which easily is the case in the above scenarios - does the worst case then become an even worse case?
I wouldn't go into one of these, considering the mentioned scenarios. Depending on the circumstances, survival can be more horrifying than the perspective of death. I would prefer to stay with and assist those I feel love and/or loyalty for, and once the time has come consider honourful suicide, or just let things happen to me, depending on what "things" are.
At one time, all things come to an end, and we all have to leave the show. The only real question is
how we leave it: yelling, strampling, and hysterically acting, or - well,
differently.
