Allen does a great job of demystifying sharks and shark attacks, offering factual information and solid explanations for shark behavior while still indulging our curiosity for gruesome details with personal stories. The reality is that sharks occupy a vital role in the ecology of the seas by removing the weakest, the sick and the dead so that the fittest survive. The shark is evolution in action, the epitome of natural selection. After reading about shark attacks for an hour or two, you might not want to set foot in anything more adventurous than your bathtub. Never swim alone.
Sharks are more likely to attack a lone person.
Don't swim where sharks congregate, such as between sandbars, near steep drop offs or near channels. Don't swim in dirty or turbid water. Don't wear shiny jewelry because the reflected light resembles the sheen of fish scales. So I guess we win. Bees, wasps and snakes kill more people than sharks do.
