To celebrate the world population hitting 7 billion, the BBC has put together this awesome app that tells you what number person you are to have "ever lived" and of those "currently alive" on earth. According to the app, I'm the 78,568,420,721st person to have lived since history began, that's a big number!

You'll also learn other interesting facts about population growth, death rates, etc. Find out your number after the jump and share it in the comment area.
