One word: Italy.
Italy? OK
They have nearly twice as much percentage of their population over age 65 compared to the US. (22 %vs. 13%)plus they are all living on top of each other (500 people per square mile vs 100 people per square mile ) compared to the U.S. . Their healthcare system is socialized which means lesser quality.
