Several weeks ago I wrote that Debbie, the world’s oldest polar bear, had suffered a number of strokes. Her zoo keepers in Winnipeg decided she had suffered enough and painlessly ended her life. I also mentioned a good friend who, unlike Debbie, had endured an agonizing death. And I asked readers whether we needed a Society For The Prevention Of Cruelty To Humans (SPCH). I’ve spent hours reading the huge response, surprised by the reaction.
