Obviously swimming in the ocean when sharks are around is dangerous and you are playing a reverse odds lottery. But statistically speaking not swimming due to sharks is kind of like not flying out of fear of an airplane accident. Drowning is WAYYY more likely to kill you (so is driving to the beach etc..) and sharks aren't even near the top-10 of animals that kill people. Its the fear and mysterious vulnerability of being in the water that freaks people out about shark attacks and maybe that Jaws is one of the best movies ever.
