Can't promise a perfect memory, but I've read almost every contribution made over the past 2 years, and I like to see where people are from. People seem to have different problems depending where they are at. Sometimes it's environmental, sometimes social.
I was reminded how westerners and easteners (US) handle earthquakes. An eastener asked me how I knew the difference between an earthquake and the 60 ton press going off. BTW this feels like someone dropping the floor and inch and you suddenly falling back to it, every 5 seconds. I related back to when the ground really shook... yes I worked at a place right next door the train tracks. When ever freight trains when by, we had to pass out valium to the easteners. Back then the answer was quite simple, if the shaking lasts for a minute then it's a train, relax, if it only lasts a few seconds then panic run out of the building screaming with arms held high.

Now the typical western response is to pick up ones coffee roll the chair back into the aile just in case the desk falls over and to get out from under the lights.
