Possible*

Sensible planning for unlikely realities can pay off big in the long run. If gravity is suddenly reversed, or the dead rise and consume the living, do you have a plan? The panic of the moment is not conducive to effective decision making.

Spend a few moments each day jotting down rational solutions to unconventional "emergencies," such as the discovery of robots from another planet (or this planet) bent on total destruction. In the midst of the chaos of the unprepared, your prior proper planning could save not just your own ass, but the ass of mankind.
