Straight from the book, Flu Pandemic and You: A Canadian Guide, by Vincent Lam and Colin Lee, a tip for avoiding the swine flu pandemic is to buy (and ride) a bicycle, among other things.
Get a bicycle (automobiles keep you from interacting closely with people, but there is the potential problem of fuel shortages).
The reasoning being that bicycles help you to maintain your distance from other (possibly infected) people. I like how they suggest an apocalyptic scenario where so many people will fall ill that we will run out of fuel.
