Italians swear by the medicinal value of the natural iodine content in the sea. It cures everything from an upset stomach to brain cancer, they say. In the summer Italians wade in the low end of the sea, lapping up the iodine, storing it for the long months ahead when they will live, cruelly, in an iodine-deficient environment. Here's Xtina at that nature riserve of Torre Guaceto. I liked it because of the incredible snorkeling in the reefs just off to the right.
