Um, what??…

Korean scientists think they have determined what caused a 39-story Seoul skyscraper to shake violently for 10 minutes, causing the building to be evacuated for two days. Earthquake? Nope. Gale-force winds? Sorry. Volcanic activity? Unh-uh. No, the culprit, they say, was 17-middle-aged gym rats working off the midriff bulge in a Tae Bo class. Apparently, while dancing and boxing to “The Power” by Snap on July 5, the exercisers not only shook their booties, they shook the building.

Just goes to show you really do have to be prepared for anything. Whether it’s a real earthquake or just your coworkers groovin’ to Tae Bo, you better know how to drop, cover, hold-on.
You’ve got the power (sorry, I couldn’t resist) to be prepared.
