Once upon a time, a king used to rule over the Greeks. Every king in other countries is fit and healthy. But this king was a different one, he is a lazy king. One day, the king fell ill many doctors came to cure him. But they all failed to do so because they knew that the king has fallen sick because he does not exercise if they say to the king they think that the king would ignore them and would punish them. But there was a very clever doctor. He went to the king said that he could cure him. The king agreed without thinking because he wants to be healthy again. The doctor checked him after that he went out of the room,after some time he came with heavy balls. He went to the king told him that this is a magic ball and also told him that he should lift this ball every morning or evening. The king followed the doctor’s advice after, some days the king saw many changes in him. He paid the doctor a huge amount and also appointed him as the royal doctor. The foolish king never realized that the balls which the doctor gave to him was not magical but an ordinary ball!
