once upon a time, the world ran out of wifi. in that same moment, millions and trillions and septillions of people died. the world could not live without wifi. the only surviviors were those who. . . there were no survivors. that day, Hades wished he could be dead himself. the end :)
That would be a practical exercise. Practical means the actual doing or use of something rather than with theory and ideas. So it would apply to real life situations.
