I read an interesting story last week. One day, a diver is enjoying the sea 20 feet below its surface. He noticed a man at same depth, but without any equipments. The diver went below other 20 feet, and the man joined in him a few minutes later. She went below 20 feet again, and after several minutes, the man following him again. This confused the diver, but he took a blackboard out and wrote, “How on earth are you able to stay this deep with nothing to help you?” The man took the blackboard, rubbed that the diver had written and wrote, “I’m drowned, you fool!”
