In what country would you have the best chance of living to an old age? Of course, that depends on many things.
But we do know that Austria has a higher percentage of senior citizens in its population than any other country on earth. Close to 15 percent of all Austrians are over the age of 65. In the United States, 11 percent of the population is over that age.
On the other hand, there are about ten countries with a senior citizen population of less than 3 percent!
