Had much worse in the past,
that might count for something, in major flu outbreaks it generally the older populations that get milder symptoms as they've encountered flu in earlier outbreaks and their immune system deals with it better. Similarly, someone like yourself who works in a populous workplace (like schools, colleges, hospitals) will encounter a lot of bugs too. God knows I did when i worked in a prison . People who've had less exposure in the past tend to get much more severe symptoms. I know people who had blood squirting out of their arses* in the 60's outbreaks, but their parents generation who lived through the really dire epidemics in the early 20th century just shrugged it off.
*I don't think those are the 'flu-like' symptoms my packet of lemsip are referring to.
Incidentally, my folks have just been release back into society after being quarantined for a week - full spacesuit visits the lot. The came up clear for swine flu, although their symptoms were the same. The virus is wide spread enough now that people won't routinely get tested anymore, they'll just be treated and asked to behave as if they have (ie. told to avoid giving lurgy to anyone else). There are definately a lot of coughs and colds around just now too
