I'm not saying that everyone should swim with sharks, but sometimes you have to jump over your own shadow in order to learn something that you will never forget for the rest of your life. Then you know you can conquer your fears. ↗
Watching Jaws just scared the living daylights out of me when I was young. I know a lot of people my age who are still petrified of sharks because of that film. ↗
I mention this fact as tending to support what I have often heard stated, namely, that a shark's sense of smell is so keen that, if men ever bathe in seas where they are found, a shark is almost sure to appear directly afterwards. ↗
