Prayers on their way! Bionic Pet Talker indeed! When I had some brain surgery (pre-Pet Talk days) I was tempted to ask if, while they were in there, they could add a chip or two - maybe one that'd enable me to be a polyglot, or at least be better co-ordinated, but alas, they declined, and resealed the "hatch," too. Some day, humans'll be upgradable! Here's hoping your knee will be!
