Henry Allingham has died at aged 113. He was reputed to be the oldest man in the World.
He may also have been one of the last 3 or 4 survivors of World War I.
In his later years, he was a tireless advocate for Peace. I think that he understood the following WWI "statistics".
The total number of casualties in World War I, both military and civilian, were about 37 million: 16 million deaths and 21 million wounded. The total number of deaths includes 9.7 million military personnel and about 6.8 million civilians. The Entente Powers (also known as the Allies) lost 5.7 million soldiers and the Central Powers about 4 million.
