Top 6 Inventions Of All Time?

It's Monday, the start of another week. Thinking about productivity and stumble across Raconteur's list of the top 6 inventions of all time. Strangely, paper was excluded from the list even though 3 of the inventions all revolve around it (writing, printing, and language). Personally, I would expand expand the list to 10 and include paper, indoor plumbing, refrigerator, and airplane.
