Epidemics

I am not too concerned about Swine flu. But I think there is a cause for concern.
3 years ago - Chinese year of the Cow saw us with Mad-Cow disease.
2 Years ago - Chinese year of the Bird and we had Avian Flu.
This year - Chinese year of the Pig and we are suffering from Swine Flu.

Next year is the Year of the Cock! Anybody else worried?
