According to Hugh Thomas, author of 'A History of the World', the greatest medical advance in history has been garbage collection. The greatest psychological advance in history is just around the corner and will also have to do with cleaning up. Cleaning up lies and "coming out of the closet" is getting more attention these days. Some day we will look back on these years of suffocation in bullsh*t in the same way we look back on all the years people lived in, and died from, their garbage.
