City workers transport a load of sandbags to be used in re-enforcing a levee gate past the Yazoo & Mississippi Valley Railroad Station May 11, 2011 in Vicksburg, Mississippi. The Mississippi river at Vicksburg is expected to crest at a record 58.5 feet. Heavy rains have left the ground saturated, rivers swollen, and have caused widespread flooding in Missouri, Illinois, Kentucky, Tennessee, and Arkansas. (Photo by Scott Olson/Getty Images)

Hauling cocaine out of the remote valley is about the only way to earn decent cash in this region where a farmhand earns less than $10 a day. Beyond extinguishing young lives, the practice has packed Peru's highland prisons with cocaine backpackers while their bosses evade incarceration. (Photo by Rodrigo Abd/AP Photo)

Factory landlord Lawrence Taylor (L), portraying a Colour Sergeant from the King's Royal Rifle Corps, part of the Rifles Living History Society, performs a drill with Connor Young (R) of the Queen's Own Royal West Kent Regiment Living History Group as they recreate the life of a First World War soldier at the Eden Valley Museum in Edenbridge in southeast England May 10, 2014. Lawrence has always had an interest in military history and specifically “The Rifles” – his veteran father's WWII regiment. When he became a re-enactor he chose not to re-enact WWII as many of the veterans are still alive, and he felt uncomfortable as he remembers his father would have flashbacks and nightmares about the war. United by a fascination with military history and a fondness for dressing up, groups such as the Rifles Living History Society and the Queen's Own Royal West Kent Regiment Living History Group get together to recreate aspects of life during the First World War. Reuters photographer Luke MacGregor photographed members of the groups, both as they took part in living history events and at their day jobs. (Photo by Luke MacGregor/Reuters)

In this March 31, 2019 photo, an Egyptian student borrows a Bedouin wedding dress to pose for a photograph with Bedouin men from the Hamada tribe, in Wadi Sahw, Abu Zenima, in South Sinai, Egypt. Four Bedouin women are for the first time leading tours in Egypt’s Sinai Peninsula, breaking new ground in their deeply conservative community, where women almost never work outside the home or interact with outsiders. The tourists can only be women, and the tours can’t go overnight. Each day before the sun sets, the group returns to the Hamada’s home village in Wadi Sahu, a narrow desert valley.

“The Eiffel Tower (French: La Tour Eiffel, nickname La dame de fer, the iron lady) is a puddle iron lattice tower located on the Champ de Mars in Paris. Built in 1889, it has become both a global icon of France and one of the most recognizable structures in the world. The tower is the tallest building in Paris and the most-visited paid monument in the world. Named for its designer, engineer Gustave Eiffel, the tower was built as the entrance arch to the 1889 World's Fair. The tower stands 324 metres (1,063 ft) tall, about the same height as an 81-storey building”. – Wikipedia
