Another possibility

We loved living near the ocean in Central America. We would drive to the nearest beach and swim. However, it was not the safest place to swim, they had undercurrents. One time I got caught in one and came down on the bottom on my head. It was difficult to breathe and to talk for weeks. Could this be the cause. I don’t know. I mentioned it to one of my doctors, I think they blew me off.

The smell of the salty air is so healing. Just to watch it is relaxing, as it carries your troubles out to sea with it.
