And now for something completely different!
From the NZ Herald comes word that China has warned its citizens against using the rack to lengthen their legs after several such operations resulted in disfigurement. The operation involves breaking the patient's legs and then stretching them on a rack.
I always thought the rack was an instrument of torture, not a surgical device. However, there is a vertically challenged dictator just across the border in North Korea who could benefit greatly from this procedure.
