Cuban farmhand Bienvenido Castillo, nicknamed Lilly, takes the cows to the pasture on his neighbour's dairy farm in Aranguito near Havana, before sunrise May 21, 2012. Lilly has been working as a cow herder and animal breeder for the past 25 years. In spite of his age at 74-years-old and having underwent a colostomy, he works some 16 hours and walks at least 9 miles (14 km) a day. The milk from the cows he raises is collected and brought to a state cooperative and then distributed to schools, old folks' homes and state rationing shops. Picture taken May 21, 2012.
