Details are as follows:

Santiago, an old Cuban fisherman, has not caught a fish for 84 days. On this day, he met with good luck. He caught a huge marlin. He twisted six sets of ropes together to drag the fish, and almost broke the rope. Just as the old man was happy to go home, he met a shark. Sharks keep attacking big fish. The old man struggled with the shark alone on the boat, beating, poking and stabbing, exhausted. Sharks still eat all the places where big fish can eat. The old man dragged the huge fish skeleton back to the shore. But the old man said, "People are not used to be defeated." You can destroy a man, but you can't defeat him. "The old man's words became the spiritual symbol of the image of" tough guy "in American literature.
