On the common sneeze

I sneezed myself awake last night and spent the rest of a dark hour worrying that I have come down with the dreaded lurgie. I spent two hours on London double deckers getting across town yesterday, shuddering at every hard surface I had to touch and glancing in horror at each fellow passenger that happened to cough. But I refuse to add to the situation by worrying about it, although perhaps it may be a good thing to have swine flu while it is still a relatively mild strain... Ah, the power of fear!
