In this June 12, 2017 photo, a woman stands in front of a mural on the slope in Central district, Hong Kong. Once known as Victoria after the British queen, Hong Kong island's waterfront formed the core of the British settlement after Hong Kong island was handed over as a colony in 1842. Today as Hong Kong approaches the 20th anniversary of its return to China, it remains a bustling commercial and financial center as well as the location of the main government offices. However, along the streets that angle sharply upward toward the mountains above, a more relaxed pace of life endures. (AP Photo/Kin Cheung)

Zulmira Jesus poses for a portrait at a street in Povoa de Agracoes, near Chaves, Portugal April 19, 2016. In the villages of Agracoes and Povoa de Agracoe, the steady drip-drip of emigration has brought down population numbers from more than 50 residents to fewer than a dozen each. These remaining villagers share the same glum acceptance that, after they have gone, their villages will die out too. It is the same desolate picture in scores of other backwater settlements in Portugal's interior, north to south. (Photo by Rafael Marchante/Reuters)
