Having been one who grew up during through the cold war in the 80s, it's just something you have to accept. I remember in 4th grade on the playground, the kids (me) were debating with the teacher whether it was better to stand outside and get nuked or go inside and live through the aftermath.

Having said that and having lived through all this before and nothing happened, I wouldn't worry too much. Also read Alas Babylon, it's pretty good and related.

On a side note, we could also get hit by an asteroid at any time with no notice, so there's always something to make you unease if you dwell on it.
