When you go scuba diving it is a good idea NOT to wear watches, jewelry, or anything shiny! Fish and sharks are attracted to shiny objects. If you are ever in a situation where a shark is swimming at you, DON'T try to swim away! Instead swim at it so it knows you are not scared of it.
My young(but smart) cousin told me these tips. I will now feel much safer when I am surfing and scuba diving!
