At Marco's Training School, I all give him training about how to deal with shark.

We have both eyes forward. They have on the sides. Stand in front of a shark, it cannot see you. It's got a blind eye. All that you have to do is to be right ahead of a shark and freeze for some time. Either he'll just swim past you or move away. But you need that little confidence in yourself to stare in his eyes. Animals normally attack you when they can smell the release of adrenaline in you.

Which is fear. Fear. When you feel fear, they'll be thinking to attack.

They can smell your fear. You can be that in a tropical water scenario, we will not have those sharks which will come and unprovocatively attack you. We are in safe waters.
