I have talked myself right out of the water more than once after feeling something bump my leg.
Yes, it is irrational, but the idea of sharks near my legs scare the heck outta me.
My neighbor pilots choppers out of Clearwater and goes out over the beaches on the weekends quite a bit. He’s taken pictures from the chopper showing people in the water seemingly oblivious to the hammerheads swimming a few yards away. We can’t see into the water very well when we’re in it up to our chests, but I assure you there are more sharks in the shallows than you’ll ever know. That fact alone should make you comfortable about being around them. Humans are not on shark menus.
