“The most serious health problem in the U.S. today is obesity.” Sounds familiar, doesn’t it? But that pronouncement about obesity’s primacy in the hierarchy of national health problems is not new. Rather, it’s the opening line to a remarkable article published 60 years ago in LIFE magazine. This photographs made by Martha Holmes to illustrate that March 1954 article, titled “The Plague of Overweight.” Photo: Dorothy Bradley (left), photographed for LIFE magazine article on obesity, 1949.

In this May 24, 2016 photo, a young boy descends the Qullqip'unqu mountain looking out at the tens of thousands of pilgrims gathered to celebrate the three-day festival Qoyllur Rit’i, translated from the Quechua language as Snow Star, in the Andean Sinakara Valley, in Peru's Cusco region. The celebration that mixes Catholic and indigenous beliefs honors Jesus as well as the area’s glacier, which is considered sacred among some indigenous people. While the native celebration is far older, the Christian part of the ritual stretches back to the 1700s, when Jesus is said to have appeared to a young shepherd in the form of another boy.
