Look! Another reason to be thankful. Evidently we've had another close call with an asteroid: an object discovered just two days ago, that approximates the size of the one which hit Siberia a century ago and leveled 800 miles of forest. Ever see "Deep Impact?" Since we don't need Morgan Freeman to stand in as our black President anymore, I guess we'd better make sure we're not recruiting septuagenarians to the space program; otherwise it'll be life imitating art, and the entire Eastern seaboard will be wiped out. Prozac, anyone?
