Hindsight is 20/20. If you weren't alive during the cold war, you're going to have no idea how terrifying it was. I was born just after it ended, but my parents grew up in the tick of it, and their fears and strange ticks they developed in the days of "Duck and Cover" under your desk where prevalent in how they raised my siblings and I.
