The exam was marked by the announcement that the panda's incredibly large head would necessitate its euthanasia in order to prevent an otherwise shortened and miserable life. "The time is now," stated Belinda Foster, pediatric assistant at the zoo, "to end this sad tragedy before it takes its logical downturn." (Associated Press)
