I don't spend every waking moment stopping lots of things that could kill us all. Nuclear war, climate change, gain-of-function research.

I just don't care that much about things that kill everyone. I don't think almost anyone does. In the Cold War, the vast majority of the population was not doing absolutely everything to achieve bilateral disarmament. This would lead you to believe that they didn't really expect nuclear war. But maybe they were just apathetic and helpless.
