A tourist is traveling with a guide through one of the thickest jungles in Latin America, when he comes across an ancient Mayan temple. The tourist is entranced by the temple and asks the guide for details. The guide states that archaeologists are carrying out excavations and are still finding great treasures. The tourist then queries how old the temple is.
"This temple is 2,503 years old," replies the guide.
Impressed at this accurate dating, he asks how he knew this precise figure.
"Easy," replies the guide. "The archaeologists said the temple was 2,500 years old, and that was three years ago."
