A one hundred and twelve-year-old Holocaust survivor is the world's oldest living man. Israel Kristal has been given that official title by the Guinness Book of World Records.
Chaim Kristal, son of Israel Kristal: "My father is a very optimistic person. When he saw a glass with half water, he is very pleased with the half of water that is full. He never sees half who is empty, he never see."
Israel was born in Poland. He moved to Israel in 1950 after surviving the Auschwitz death camp.
