Original caption: "Kabul University students changing classes. Enrollment has doubled in last four years."
The physical campus of Kabul University, pictured here, does not look very different today. But the people do. In the 1950s and '60s, students wore Western-style clothing; young men and women interacted relatively freely. Today, women cover their heads and much of their bodies, even in Kabul. A half-century later, men and women inhabit much more separate worlds.
