Until recently, Zvi was a happily married seventy-year-old engineer with no worrisome ailments beyond those of age. His road projects connected one place to another and opened tunnels of light deep in the mountains. But lately he forgets some names. A visit to the neurologist confirms it: first signs of his decline. Zvi, encouraged by his wife and the specialist, will not give up.
