"This disease eats our kidneys from inside us," Martinez said. "We don't want to die, and we feel grief because we already know that we're hopeless." Jesus Ignacio Flores of Nicaragua started working when he was 16, laboring long hours on construction sites and in the fields of his country's biggest sugar plantation.
Three years ago his kidneys started to fail and flooded his body with toxins. He became too weak to work, wracked by cramps, headaches and vomiting.
On Jan. 19 he died on the porch of his house. He was 51.
