WHY NOT ALL OF THE ABOVE?

Most endtime texts love talking about a pestilence/disease wiping out a portion of the planet as part of armageddon. I believe it's referred to as "Wormwood" in Revelations. It also mentions a "star falling" in another act. A friend of mine who reads a lot of the other folks' versions has talked about similar interpretations. I mean, wouldn't it be crazy if we got wiped out by an antibiotic-resistant common cold, or gonorrhea?! And THEN get smacked by an errant asteroid shortly after? We're screwed, hubskibros.
