The 75-year-old lady Um Mukhtar cooks in the graveyard at a large cemetery slum at the foot of al-Muqattam hill in Cairo, Egypt, Nov. 16, 2016. Some five million Egyptians, according to official statistics, live in cemeteries due to chronic housing crisis shortage in Cairo, a city with 25 million populations. Owners of the tombs allow families to stay in the graveyards without charge as they can guard and clean the tombs. For them, poverty has erased the boundary of the living and the dead.
