How Old Is the Average Country?

Daniel_Stuckey writes with a snippet from his piece at Vice: "I did some calculations in Excel, using independence dates provided on About.com, and found the average age of a country is about 158.78 years old. Now, before anyone throws a tizzy about what makes a country a country, about nations, tribes, civilizations, ethnic categories, or about my makeshift methodology, keep in mind, I simply assessed 195 countries based on their political sovereignty. That is the occasion we're celebrating today, right?"
