Well the good thing is mr Nappy, if we continue your bright spirit, if it is indeed true that the world would come to an end the 21th of December -which is not the case obviously- there isn't any guarantee you will see that day at all....You could be hit by a train, a car, an elk, a meteorite, an umbrella, a child, a hartattack or anything else that makes an end to your earthly existence....Isn't that comforting? You do not need to worry whether you'll make it to 21-12-12....
