I remember watching Saturday morning cartoons as a kid. I watched my cartoon heroes face all kinds of perils. I learned that if you venture into the ocean, you will be immediately circled by sharks. If you wander too far into the woods, you will soon be sucked into quicksand. Finally, if you end up on a tropical island, you will be captured by cannibals.
Since those idyllic days, I became a SCUBA diver. I have spent a lot of time swimming, snorkeling, and diving in the ocean. I have seen sharks, but they have never surrounded or circled me.
