I relax my throat and take a very deep inhale into the pit of my stomach, then exhale completely. Inhale again, and repeat. “All the way in and all the way out,” says Pinheiro. “Keep going! Keep breathing!” • • • There it is, again. And here I am, again. That ringing in the ears. The heavy-metal double-bass drum thumping in my chest. The warm static flowing to my shoulders and face. The wave comes, washes over and runs up, then turns around and recedes, back to the ocean.
