We’re alive because nothing bad happened to us. And nothing bad happened because a lot of good things happened. Vaccines. Food safety laws. Automobile and road safety regulations. Not sexy. Not headline news. Just life-saving.

Preparation, prevention, regulations, and safeguards prevent catastrophes all the time, but we seldom think or hear about it because “world continues to function” is not interesting news. We have to rely on statistical analysis and the expert opinions of planners and officials in order to evaluate both crucial next steps and the effectiveness of preparatory measures after the fact, and that can be challenging for us to pay attention to. So we tend to forget that preparation & prevention is necessary and discount it the next time around.
