What if you were involved in an event that is "other than" the best ever for yourself or family? A giant wave 200 ft high crashes on the shore, a meteor hits the Earth, a hurricane strikes nearby, these are not necessarily negative events they can be challenges. Now suppose you are in an area where there is a need for a military quarantine because of a pandemic outbreak of a deadly virus. And suppose you don't want to stay in the quarantined area. You would need to take immediate action to get out. Going by vehicle would not be an option most likely unless you were very fast and there were many backroads available. A more likely reality would be that you may need to hike through a wooded area away from roads. Weighing your available options and making a fast decision would help you acheive your desired goal.
