Martin: Extreme sports are popular all over the world. People enjoy the adventure and fun. I am one of them. I like extreme sports because they are exciting. I tried paragliding before and I enjoyed it. Then, I tried water extreme sports such as diving, kayaking and rafting. They are all exciting, but I enjoy exploring the fish and sea animals the most. I thinK it is more amusing than all other sports. I also take photos of different kinds of fish.
