Man with a great-great-great grandchild

For some reason, I've been wondering lately if anybody lived to see children beyond great-great grandchildren. Apparently, you can. A British man is now the world's oldest man, at 113 years old. He's a WWI veteran and a founding member of the Royal Air Force. According to Reuters, "Allingham's life has spanned three centuries and six monarchs, starting with Queen Victoria. He has five grandchildren, 12 great-grandchildren, 14 great-great grandchildren and one great-great-great grandchild." I tried to link the photo, but had trouble. Here's the link to the story, but trust me, he's old-looking. He looks a bit like the Emperor.
