George Burgess, the director of the International Shark Attack File at the University of Florida, announced today that fatal attacks from the toothy predators dropped to a two-decade low worldwide. Only a single swimmer was lost in 2007, compared to four each in the two years before. Granted, that doesnt mean sharks are leaving us alone completely. The number of attacks actually increased from 2006 to 2007, jumping from 63 to 71.
