There are 7 billion people alive today. In 1900, the world population is estimated to have been only 1.5 billion. So projecting further backwards in history, it would seem that probably quite a large percentage of all humans that ever lived are alive now. This means that a majority of all butt wipes, dick wads, pricks, bastards, assholes, dumb fucks, thugs, thieves, murderers, and cads who ever lived are still alive and in our midst right now. Nice...
