Utah is known for its fabulous skiing, beautiful national parks (five of them, the most in the country) and clean living, but it's also recognized as one of the best states for successful aging according to an index released by the Milken Institute on November 18. Provo was ranked third and Salt Lake City was ranked fifth of 352 U.S. cities in their index, which realizes that most Americans want to age at home and in place as opposed to moving somewhere else to retire.
