Doctors detected a tumor on Inge’s brain when she was a small child. She lost her sight completely at age 10. Davor was born almost totally blind; he has 5% sight. I met this couple on the Adriatic island of Hvar, known for its ancient castle walls, slippery stone walkways and hilly paths. When I expressed my amazement that they could navigate this town’s crazy maze of shops and houses with just a cane, they laughed and said they were born here – they know every inch of the place like the backs of their hands.
