We know 42 is the answer to life, the universe, and everything. It's also the answer when you ask how many national emergencies the US has right now. Why so many? Can you name any of them? Don't they expire at sometime or another? Well, first we have to define "national emergency." The idea is not in the Constitution at all, and it was only codified in the 1970s, but that bill was quite broad and led to what we have now. The US President can declare a national emergency, and then do all kinds of things that may or may not have anything to do with the emergency at hand. Whether or not that's a good thing depends on the situation, but since we have 42 current "situations," that's an awful lot of power to hand to one person. Half as Interesting takes the regulations the way they exist now and runs them with some utterly ridiculous possible scenarios. Let's hope that cooler heads prevail.
