Fatal shark attack

I feel very sorry for him and his family. He seemed like a nice guy. I have 3 kites for about 4 years now and still haven't learned how to kite surf because of my fear of sharks. I just cant stop thinking about what is in the water. I did however buy a diving knife kit that I can strap to he back of my arm with rubber belts and I can grab the knife whenever I need to. I feel just a bit safer but would like to get a second smaller one I can put on my knee. It was on amazon for like 10$. Even still I am still afraid of sharks. I wish I just knew how to surf so I can stay up on the board and know how to relaunch quickly. Hopefully his family does well.
