“I am old, not senile,”
“I am in the prime of senility.”
“Death is coming—but hopefully not before old age, decrepitude, and senility. ”
“Anyone who claimed that old age had brought them patience was either lying or senile.”
“She appeared to be ageless the type that would continue, unchanging, until she was an old woman when she would suddenly become senile and die”
“I'm not senile," I snapped. "If I burn the house down it will be on purpose.”
