I am not a swimmer yet. I was born a swimmer. It would be unwise of me to relax in water. If I relax in water, I might lose control. I may not have adequate lung capacity to swim.
Deep water works differently than shallow water.
My mind works differently in deep water than it does in shallow water. It would be unwise of me to relax in deep water. If I relax in deep water, something dreadful will happen. I don't get another one. I can't control my body well in deep water.
