Those of us who lived during the cold war spent 40 years where we originally practiced duck-and-cover (my parents) and then understood the futility of the idea.

Those of us who lived during the cold war spent 40 years where we originally practiced duck-and-cover (my parents) and then understood the futility of the idea. We came to rely on the belief in MAD and relegated that worry (no longer fear) to the back of our minds. You are worrying about a non-zero (but small) chance of nuclear war when there are so many easier ways to die in this world (riding in a car). Instead of being scared, demotivated and depressed about war in the Ukraine, find a way to spend that nervous energy productively. Maybe join the Ukraine IT Force?
