Today I worked on my thesis for about four hours, had a light lunch, then walked to the supermarket in a different direction. And I only got slightly lost once. One thing I have lost as I've got older is my once-excellent bump of direction. But today it was a good lost: I the found renaissance fort that was built into the Arab-Roman city walls to protect the city from the pirate attacks that caused it to decline in the 16th and 17th centuries. Today it's a museum of modern art.
