The sea area with sharks around the beach. Most people often worry. And the need to think it were coming at the beach? Or it will attack us when it cannot know. But if the locals that he may be accustomed to it than to not feel anxious very much. But go back to the sea area that rarely sharks appear or none at all. People will not feel worried about it when going to swim or play around on the beach. But if I answer would say worry because we ourselves swimming is not hard and always worry about everything in the sea, especially dangerous animals like sharks.
