The old woman walks on the Tunis street, pulling a trolley made from the remains of a child's pram. She gathers discarded bread and sells it by weight to a livestock feed processor. "I work from sunrise to sunset, summer and winter," Aljia says. On the best of days, the elderly widow makes just one or two dinars. "I do not find pleasure in this exhausting work, but who would provide for me if I stopped moving?" she asks.
