Nasrudin and some others were in the town square one day, and the topic of conversation turned to how they changed since they were younger. Some of them talked about how they were wiser, and some talked about how they were weaker. Nasrudin spoke up and said, “Not only am I wiser than I used to be, I’m as strong as I was in my youth.”
“Are you sure?” One of them asked.
“Yes. I’ve tested it,” Nasrudin replied.
“How did you test it?” they asked.
“Well, there is this big rock outside my house. I couldn’t lift it when I was young, and I still can’t lift it now.”
