Nice illustration. My first thought however when reading "The average human height is approximately 6 feet (2 meters)" was: "Wow, Americans are tall!". (Given my geography, I'm used to human sizes given in meters). Then I visited www.unitconversion.org and found out that 6 feet is more like 1.82 meters and 2 meters are over 6 feet and 6 inches. A nice sideeffect of this nitpicking (sorry about that by the way) is that I now know that my own height is 230 barleycorn and the weight I don't want to exceed is 500'000 carat. Gotta love round numbers
Thanks for making me learn something today!
