In this fascinating study of people and their diets, 80 profiles are organized by the total number of calories each person puts away in a day. Featuring a Japanese sumo wrestler, a Massai herdswoman, world-renowned Spanish chef Ferran Adria, an American competitive eater, and more, these compulsively readable personal stories also include demographic particulars, including age, activity level, height, and weight.

In the spring of 1965, within weeks of 3,500 American Marines arriving in Vietnam, a 39-year-old Briton named Larry Burrows began work on a feature for LIFE magazine, chronicling the day-to-day experience of U.S. troops on the ground – and in the air – in the midst of the rapidly widening war. The photographs in this gallery focus on a calamitous March 31, 1965, helicopter mission; Burrows’ “report from Da Nang”, featuring his pictures and his personal account of the harrowing operation, was published two weeks later as a now-famous cover story in the April 16, 1965, issue of LIFE.

People throw turnips at the Jarramplas as he comes out from the church beating his drum during the Jarramplas Festival on January 20, 2016 in Piornal, Caceres province, Spain. The centuries old Jarramplas festival takes place annually every January 19-20 on Saint Sebastian Day and this year they expect to use more than 20 thousand kilogrames of turnips. Even though the exact origins of the festival are not known, various theories exist including the mythological punishment of Caco by Hercules, a relation to ceremonies celebrated by the American Indians that were seen by the first conquerors, to a cattle thief ridiculed and expelled by his village neighbours. It is generally believed to symbolize the expulsion of everything bad. (Photo by Pablo Blazquez Dominguez/Getty Images)

“Newton was born in Berlin, the son of Klara “Claire” (Marquis) and Max Neustädter, a button factory owner. His family was Jewish. Newton attended the Heinrich-von-Treitschke-Realgymnasium and the American School in Berlin. Interested in photography from the age of 12 when he purchased his first camera, he worked for the German photographer Yva (Elsie Neulander Simon) from 1936. The increasingly oppressive restrictions placed on Jews by the Nuremberg laws meant that his father lost control of the factory in which he manufactured buttons and buckles; he was briefly interned in a concentration camp on “Kristallnacht”, November 9, 1938, which finally compelled the family to leave Germany. Newton's parents fled to South America. He was issued with a passport just after turning 18, and left Germany on December 5, 1938. At Trieste he boarded the “Conte Rosso” (along with about 200 others escaping the Nazis) intending to journey to China. After arriving in Singapore he found he was able to remain there, first and briefly as a photographer for the Straits Times and then as a portrait photographer”. – Wikipedia
