In this April 23, 2015 photo, Salama Osman, left, a migrant worker, rides a train back to his job as a "bawaab" or doorkeeper in a Cairo apartment building, near his home village of Abu al-Nasr, about 770 kilometers (480 miles) south of Cairo. Osman, 46, is returning from one of his two trips a year back home. The money he makes in Cairo can support his wife, Amira, and his four children, forcing him to continue his life in the big city.
