I've always been scared of sharks. It seems like the most natural thing in the world to be afraid of. I instinctively haven't forgotten what it was like for my ancestors to swim around in that big, scary ocean, before they ever went up on land.
Either way, tons of people dive, not just in local lakes, but frequently out in the sea or even near land at a beach attached to the "open sea".
How do they dare to do this? Do they simply go by statistics, saying that there are few or no known shark attacks in this area for the last X years? Of course, this says nothing about those who dive without telling anyone beforehand, or don't even dive, but simply just were in the water, swimming, when a shark got them and pulled them far away, never to be seen or heard from again.
Maybe sharks "normally" don't hang around the beaches, although I would if I were a shark, since a bunch of juicy humans hang around there. Nevertheless, the fact remains that nothing physically stops the sharks from simply going to that area, or ending up there by random chance. And then it's game over if they see me.
Few deaths probably are as frightening as trying to scream for help under water as you see these unsympathetic, remorseless predators of the sea coming for you, opening their jaws to let you see the razor-sharp teeth a split second before you are bitten, bleeding as it shakes your helpless body around and pulls it away. Shudder.
To tell you the truth, I would never even dive or swim in a lake surrounded by land, far away from the shore. Who knows what's down there in the dark, unknown water? I'm not even sure I want to know...
Do people simply have no concern for their own safety? Do they consider it "worth it" to risk getting eaten by a fierce watery beast just to get to experience being under water like their ancestors millions of years ago? I will admit that it probably would be fun, if sharklessness could be guaranteed, but I'd just be worrying and fearing for my life every second of the experience and it would ruin any enjoyment down there. No "promises" by "experts" or statistics would convince me otherwise.
