Well, that video is a great illustration of why it is safer in the ocean than in a car.
About fear: I don't believe it helps the fearful person when other people dismiss the validity of the fear or sugar-coat the facts:
more people are killed by cows every year than by sharks.

People in the water do not get killed by cows; they don't get hit by vending machines. People in the water do drown and they do get attacked by sharks. While swimming in the ocean, you are far more likely to get bitten by a shark than you are to be involved in an car crash.
So why do I continue to dive and hunt in the ocean? Because I have educated myself on how drownings and shark attacks are most likely to occur and I take steps to avoid those situations. I have great respect for the awesome power of nature and I am humble in my complete powerlessness and total lack of importance in the big picture. That way I can enjoy swimming in shark habitat, skiing in avalanche terrain, and paddling mighty rapids. Death from an avalanches is not a statistical probability for the general public, but it is the leading cause of death to people who are in avalanche-prone terrain.
Be fearful of sharks, tread lightly in their house, and don't throw food scraps overboard when your boat is anchored near where people swim. End of sermon.
