On the way to the Dead Sea, Zohar warned us that the water was greasy because of the natural salts concentrated therein (magnesium, potassium, sodium, etc.). We should shower immediately after our dunk. Zohar, who seems a bit of a worry wart anyway, but has 39 grownups to herd, also advised that we not dive in, or swim, not to splash, to watch for the rocks underwater, and to never, never let the water into your eyes. Something dreadful would ensue. We were no longer sure that a dip was a good idea. We were nearly ready to pull the senior citizen card.
