Honolulu has been named the second-healthiest city in the country in which to live and retire by AARP Magazine.

The world's largest-circulation magazine said Honolulu residents spent more time exercising than almost any other city it surveyed and that an "impressive" 95 percent of residents are covered by health insurance. It also noted Honolulu has one of the highest life expectancy rates of any city.

The magazine looked at 20 measures of vitality, including clean air and water along with availability of healthcare and healthy eating habits to come up with its list of the top 10 healthiest places to live in the nation.

Ann Arbor, Mich., was named the healthiest city because of exercise rates and the high numbers of physicians per residents.
