PI,
Coelacanth. It's a rare prehistoric fish, that was thought to be extinct. It's my father's safety word. You see, his side of the family has the trait of longevity. They also have a proclivity for sinility. My father doesn't want to go that route. Everytime we meet, I ask him the safety word and he responds "coelacanth". When the day comes that he can't remember, I have agreed to take him to the woods and put him down. The only issue I see, I've drilled this word into his head, it will probably be the only thing he is yelling when he does go senile. Oh well, feel free to use it anyway.
