So, the SARS thing.
a) just a really bad flu hyped up to catastrophic proportions by the media
b) a plague set upon the world by either terrorists, a pissed off god or aliens
c) a sure sign that the end times are coming and pretty soon people will start disappearing, leaving only the heathens to roam the earth begging for forgiveness.
d) none of the above, but I have my own theory that I will take the time to spell out for you in great paranoid detail.
