I'm sure you're not the only one but what is there that we can really do about it? Worrying about it seems somewhat counterproductive - though with nasty bugs like H1N1 (and its future mutations), SARS and some form of avian flu, I have bought a few boxes of N95 face masks and hand sanitizers just in case. Some days I figure it's excessively paranoid, on others, I figure that an insurance policy for something catastrophic that costs under 50 bucks is a pretty good deal.
