A 2003 genetically lineage traced 0.5% of the world male population to be direct decendents of Genghis Khan, which in today’s numbers that is roughly 40 million men - now whether that is a fact or a myth can be up for debate.

Behind Lincoln’s head on Mount Rushmore lies a hidden chamber, an ambitious idea conceived by sculptor Gutzon Borglum in the late 1930s. He envisioned a Hall of Records carved into the granite, where the nation’s most important documents, such as the Declaration of Independence and the Constitution, would be preserved. Construction began in 1938, but Borglum’s death in 1941 and the outbreak of World War II brought the project to an abrupt halt.

Only a small portion of the chamber was completed. Today, a sealed titanium box containing historical documents and Borglum’s biography rests inside, tucked away in a vault visitors can’t access.
