...you scan the Sunday newspaper classifieds hoping to see a 70+ pound anvil
...you think _Dies the Fire_ by S.M. Stirling would be a good idea
...your survival kit includes a mortar and pestle
...you refuse to buy a fuel-injected vehicle
...your library consists of books older than you are
etcetera
