For example, residents of the Seton Hill and Downtown neighborhoods have one of the shortest life expectancies, living, on average, just under 64 years. The inhabitants of the totalitarian dictatorship in North Korea have similar life expectancies. In contrast, those in the Roland Park area can expect to live on average more than 83 years, much like the denizens of The Most Serene Republic of San Marino, a tiny nation surrounded by Italy.
