Many years ago I became an advanced open water diver. If you’ve never been scuba diving, it is the most peaceful, beautiful experience. It’s just you, the sound of your breathing, and all the wonders the ocean has to offer. Two of the reasons I chose to learn to dive are that I am claustrophobic and I am afraid of sharks. You’d think that a person with both these things would avoid diving, right? Yes, except that I cannot tolerate my choices being ruled by fear.
